�� Rated capacitive current for breaking: 20 times the rated current of the fuse
�� Fuse specification: 1-50A
Note: �� represents the rated current value

Structure and its characteristics
This type of fuse is composed of an outer arc extinguishing tube, an inner arc extinguishing tube, a fuse, an outer tension spring, and an action indicator board; The external arc extinguishing tube is composed of epoxy glass cloth tube and reverse white steel paper tube, which meets the requirements of capacitive high current breaking performance. The internal arc extinguishing tube is the first to use high-efficiency release agents. When the fuse melts and an arc is generated, the release agent releases high-efficiency non combustible gas, which greatly increases the ionization speed of the release agent compared to the arc ionization speed, quickly extinguishing the arc. Then, it is combined with an external tension spring to pull out the fuse tail wire. Therefore, its arc extinguishing ability is significantly higher than the ability to produce gas arcs solely through reverse steel paper tubes. In addition, the insulation material used for the fuse has an extremely low water absorption rate, making it less susceptible to moisture and deformation, and suitable for indoor and outdoor installation and use.

Altitude: The installation site has an altitude of no more than 1000m.
Atmospheric conditions: The average relative humidity measured within 24 hours shall not exceed 95%. And taking into account the condensation caused by temperature changes. The surrounding air is not affected by dust, smoke, corrosive or flammable gases, water vapor, or excessive pollution.

Application and scope of XRNT-35KV high-voltage current limiting fuse:
This product is suitable for indoor and outdoor AC 50Hz systems with a rated voltage of 12kV. It serves as a protective component for transformers and other power equipment against overload or short circuit.

Structure and working principle of XRNT-35KV high-voltage current limiting fuse:
A fuse is composed of a base, fuse tube, melt, impactor, filler, etc. The base is connected to external wires and forms an insertion structure with the fuse contacts, making it easy to replace.
High voltage current limiting fuses are used for full range protection, which can reliably break all fault currents between the current causing melt melting and the rated breaking current. They utilize the high breaking capacity of current limiting fuses, rather than the good small current overload protection characteristics of non current limiting fuses. By combining the breaking characteristics of two types of fuses and combining them into one, they complement each other's strengths and weaknesses, and obtain good protection characteristics for full range breaking.

Basic parameters of XRNT-35KV high-voltage current limiting fuse:
The basic parameters of the fuse are shown in Table 1 and Table 1

RNCX-15/200-12.5 type drop out fuse

[Drop out fuse]RNCX-15F Drop out fuse

2026-6-11 13:29:13

The RNCX type drop out fuse is a gas injection type distribution network fuse, whose main function is to provide protection for equipment on the distribution line that may be damaged due to fault current or overcurrent. Capable of meeting load current and capacitor current, designed and tested according to standards such as GB 15166.3, IEC 282-2, ANSI C37-41, NEMA SG2, etc.

Rated parameters of RNCX-15F drop out fuse:
The rated parameters of a fuse are rated operating voltage, rated short-circuit breaking current, and continuous operating current.
Rated voltage: represented by the line to line voltage of the system, i.e. single voltage representation (such as 12kV). The modified fuse can be applied in systems where the line voltage does not exceed the rated voltage. The base (or insulator) of the fuse shall be classified according to the rated BIL. The rated value is marked on the side of the porcelain sleeve (see Figure 1-9).
The nameplate on the melting tube indicates the rated voltage, rated current, and rated short-circuit breaking current parameters, which depend on the form of equipment ordered. Users can only use it correctly within the specified rated parameters.
Rated short-circuit breaking current: the maximum symmetrical fault current that can be successfully broken by a fuse at rated voltage. This parameter is marked on the nameplate together with the rated voltage.
Rated continuous current: The maximum rated current of the base of the RNCX fuse is 300A, and the fuse tube is divided into 100A and 200A.

RNCX-15F	fifteen	two hundred	twelve thousand and five hundred	one hundred and twenty-five	forty-five	three hundred and thirty	nine	61×35×16

RNCX-15F drop out fuse structure:
The structure of the fuse allows the use of GB standard fuses and pressure relief caps. The melting tube can be removed or inserted into the base by hook rod operation. An isolation knife can be used to replace 100A or 200A fuse tubes, thereby turning the fuse into a 300A isolation switch, and vice versa. The isolation switch can also be operated with a hook rod.
Fuses can be equipped with standard mounting brackets. Can be installed on standard columns. Pay attention to the installation angle.
4�� Operation:
Drop out fuses are high-voltage equipment that are typically operated using standard specialized tools. And attention should be paid to the correctness and safety of the operation. Use a hooked rod to pull and push the hook and loop of the melting tube (Figure 1) to complete the opening and closing operation. The opening and closing operation requires fast and stable operation to reduce the burning damage of the contact (Figure 1-2) caused by arcing. (Note: Operation safety regulations must be followed when operating any equipment)
If the drop type RNCX uses the S&C load disconnect tool, it can be used as a load disconnect device. RNCX is equipped with hooks that meet mechanical and electrical requirements (Figure 1-11). The rated load breaking parameters displayed on the nameplate of the load breaking tool indicate its function and its ability to cut loads under given circuit conditions. At the same time, confirm that the rated voltage parameters on the tool nameplate are consistent with the system voltage. To use the disconnect tool correctly and safely, please refer to the instruction manual or operating procedures that come with the disconnect tool.
Before putting the fuse into use, any obvious damage should be visually inspected, such as bent components or broken porcelain bushings (Figure 1-10) during transportation. At the same time, check the alignment between the melting tube and the base.
5�� When using GB standard fuses to reinstall the melting tube, attention should be paid to:
1) When using a used melting tube, it is necessary to check and confirm whether there are enough fibers left inside the melting tube to complete the cutting fault operation. The fuse installed with a fuse will burn the fibers inside the melting tube during continuous operation, thereby increasing the inner diameter of the melting tube.
If the inner diameter of the melting tube is greater than the following dimensions, it must be replaced:
100A melting tube, 0.65 "(16.5mm) 12.5kV/100A melting tube, 0.9" (23mm)
200A melting tube, 0.94 "(24mm)
2) Fuses of 100A and below can only be used in 100A fuse tubes. Fuses of 100A and below used for 200A melting tubes will result in serious consequences such as inability to disconnect due to overheating or low current faults.
3) The arc extinguishing tube, which is part of the fuse assembly, must not be bent or damaged before installation. Damaged melting pipes will result in the inability to disconnect small currents.
4) The pressure relief cap (Figure 1-4) should be fastened to the button head of the fuse to obtain the ideal current channel. Loose pressure relief caps can cause an increase in circuit resistance, leading to overheating or melting of fuses.
5) The fin shaped ejection plate (Figure 1-5) increases the tension of the fuse and is used to assist in the ejection of the fuse. For this, it should be locked behind the cast iron ring and pressed down by a fuse. Pull out the fuse with force (it can withstand a tensile force of about 44N), wrap the tap clockwise on the bolt, and press it under the compression nut, which has a torque of 13-20N. m. The remaining part of the tap should be cut off.
6) The pressure relief cap cannot be reused. When the fuse cuts off the fault, the top of the pressure relief cap will be broken, and it will no longer be able to secure the top button of the fuse. The components that need to be replaced are limited to caps, fuses, and fuses.
7) Although drop out fuses are designed for outdoor use, do not keep the fuse tube in a constantly open state. In this way, the opening of the melting tube is upward, which makes it easy for water to accumulate in the tube, causing the fibers to expand and leading to failure during disconnection.
8) The contacts of the fuse are silver plated and coated with a protective layer of silicone grease. Old silicone grease and accumulated dust should be cleaned up in a timely manner. The protective layer can be renewed by applying a thin layer of silicone grease. When dealing with severe natural corrosion, fine sandpaper can be used to polish the contacts. It is not recommended to use sharp metal tools as they may damage the silver plating layer.
6�� Open the box
Drop out fuses are packaged and transported in thick cardboard boxes. Be careful to avoid damaging the equipment during unboxing and installation.
Insulators are wet manufactured porcelain insulators, which are very sturdy but can also break when they come into contact with sharp objects. Once broken, it may lead to unreliable electrical insulation. Please pay special attention and handle with care!

[Drop out fuse]PRW12 Drop out fuse

2026-6-11 13:28:48

PRW12 drop out fuse and load drop out fuse are outdoor high-voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the main branch of the distribution line, used for short-circuit and overload protection of transformers and lines, as well as for breaking and closing load currents. The drop out fuse consists of an insulation bracket and a fuse tube. The static contact is installed at both ends of the insulation bracket, and the dynamic contact is installed at both ends of the fuse tube. The fuse tube consists of an inner arc extinguishing tube and an outer layer of phenolic paper tube or epoxy glass cloth tube. Load drop type fuses enhance the elasticity of auxiliary contacts and arc extinguishing covers, used for opening and closing load currents.
When a drop out fuse operates normally, the fuse tube is tensioned by the fuse to form a closed position. When the system malfunctions, the fuse quickly melts and forms an arc due to the fault current. The arc extinguishing tube is heated by the arc and decomposes a large amount of gas, creating high pressure inside the embassy and forming a longitudinal blow along the pipeline. The arc is quickly stretched and extinguished. After the fuse is blown, the lower moving contact loses tension and flips down twice, locking the mechanism and releasing the fuse tube, causing the fuse tube to fall and form a clear breaking position. When a load needs to be pulled, use an insulating rod to pull the contact. At this time, the active and stationary contacts are still in contact. Continue to pull the contact with the insulating rod, and the auxiliary contacts also separate. An arc is generated between the auxiliary contacts, and the arc is elongated in the narrow slot of the extinguishing hood. At the same time, the extinguishing hood produces gas. When the current crosses zero, the arc is extinguished.

purpose
PRW12 drop out fuse is suitable for use in 35kV and below voltage frequency 50Hz power systems as overload and short-circuit protection for transmission lines and power transformers. It is only used for opening and closing rated load currents and has a mechanical life of �� 2000 times.

Terms of Use
1. Suitable for environments with an upper limit of 40 �� and a lower limit of -30 ��.
2. Altitude not exceeding 1000m, wind speed not exceeding 35m/s
3. Fuses are not suitable for the following locations
3.1 Places with fuel or explosion hazards.
3.2 Places with severe vibrations or impacts.
3.3 Areas with heterogeneous electrochemical gas interactions and severe air pollution and smoke.

Structure Introduction
A fuse is composed of two main parts: a base and an arc extinguishing device. The lower end of the arc extinguishing tube is equipped with a spring bracket that can rotate, which always keeps the fuse in a tight state to ensure the self-locking of the arc extinguishing tube in the closed position. In case of overload or short circuit between the line and the transformer, the fuse melts and quickly withdraws from the arc extinguishing tube. The arc extinguishing tube is designed with a step-by-step exhaust to solve the contradiction of breaking large and small currents on the same fuse.

Principle of operation
The RW6G-60 outdoor high-voltage drop out fuse mainly consists of an upper static contact, an upper moving contact, a fuse tube, a lower moving contact, a lower static contact, and a rod insulator. During normal operation, the fuse locks the movable joint between the melting tube and the moving contact, so the melting tube is in the closed position under the pressure of the upper static contact. When the fuse is blown, an arc is generated inside the melting tube, and the arc extinguishing tube lining the melting tube produces a large amount of gas under the action of the arc. At the zero crossing of the current, a strong ionization effect is generated, which extinguishes the arc. Due to the melting of the fuse, the movable joint is released, causing the melting tube to sag and rapidly fall under the pushing force of the upper and lower elastic contacts and the weight of the melting tube itself, forming a clear isolation gap.

The RW10-10F RM10-10F (F) type fuse is suitable for overload and short-circuit protection of AC 10 kV distribution lines and distribution transformers for the purpose of switching rated load currents. The RW10-10F type is a type I product with a leakage ratio of 2.2. The RW10-10F (M) type is a salt spray resistant product with a leakage ratio of 3.3, suitable for use in high pollution areas, and has the same technical parameters as the 10F type. .

Structural characteristics of RW10-10F series drop out fuses
A fuse is composed of two main parts: a base and an arc extinguishing device. The working contact is designed as a bridge structure, and the lower end of the arc extinguishing tube is equipped with a rotatable spring bracket, which always keeps the fuse in a tight state to ensure the self-locking of the arc extinguishing tube when it is in the closed position. When the line or transformer is overloaded or short circuited, the fuse melts, and the spring bracket quickly extracts the fuse from the arc extinguishing tube under the action of the torsion spring. To reduce the burning time and consumption of arc extinguishing materials.
The fuse tube adopts a step-by-step exhaust structure. When breaking small fault currents, due to the closed upper end, a single end exhaust is formed, which maintains a large pressure inside the tube to extinguish the small fault currents. When breaking large short-circuit currents, the upper end is flushed open to form two end exhaust, reducing the pressure inside the tube and preventing mechanical damage to the fuse tube when breaking large short-circuit currents. Therefore, this product can reliably break any current between the upper limit current capacity and the lower limit current capacity.
The fuse is equipped with an arc extinguishing chamber and arc contacts, which can open and close the rated load current and act as a load switch. During the opening and closing operation, the arc is generated on the arc contacts and extinguished in the arc extinguishing chamber to protect the working contacts from arc burns. The arc extinguishing chamber is made of a new type of engineering plastic compression.

2026-6-11 13:19:02

RW3 and RW11 pollution resistant outdoor AC high-voltage drop out fuses consist of two main parts: insulators and melting tubes. During normal operation, the movable joints of the contacts are locked in the closed position by the fuse. After the fuse is blown, the movable joint loses tension, and the fuse tube quickly falls under the action of its own weight and elasticity, forming a clear isolation gap.
