FZW13A-12/T630 Outdoor AC High Voltage Load SwitchDetailed product description：

FZW13A-12/T630 outdoor AC high voltage load switch (hereinafter referred to as load switch) is a control device in a rated voltage 12kV, 50Hz AC three-phase high voltage distribution network. Its main purpose is to disconnect and close load currents in power lines, circulating currents in ring power grids, inductive currents of no-load transformers, and capacitive currents of capacitor banks (or cables); It also has the ability to handle short-circuit currents and withstand the electric and thermal effects of short-circuit currents.
The load switch is operated by a spring mechanism. There are two types of spring mechanisms: motor energy storage (electric) and manual energy storage (manual). The electric spring mechanism is operated by a motor (or manually operated) to store energy for closing, an electromagnet, or manual opening; The opening and closing of manual mechanisms are all done manually. The performance of the spring mechanism is very reliable.
The load switch adopts a vacuum arc extinguishing chamber device, which is suitable for frequent operation places and has the characteristics of long service life, maintenance free, no explosion, and no fire hazard. The load switch adopts an air silicone rubber composite insulation structure, which has reliable insulation performance, no hidden dangers such as oil and gas leakage, and strong adaptability to environmental conditions. The shell of the load switch comes in two types: stainless steel and ordinary steel.
This load switch can also be combined in the form of load switch isolation switch, load switch isolation switch ZnO lightning arrester, etc. according to the user's needs, and supplied in the form of combined electrical appliances. Load switches can be equipped with 2-3 current transformers of 630A-50A (rated current)/5A according to user requirements.
