FZW35-40.5./J1250-12.5 Outdoor high-voltage vacuum isolation load switchDetailed product description：

FZW35-40.5/J1250-12.5 outdoor AC high-voltage vacuum isolation load switch is suitable for AC 35KV, 50HZ power systems, mainly used for breaking load current (1250A), transformer no-load current, cable current, capacitor current, and closing short-circuit current (31.5), with functions such as breaking, isolating, connecting, and switching. Used in conjunction with fuses as a replacement for circuit breakers for transformer protection, reducing costs, it is an updated product in urban and rural power grid renovation, especially suitable for unmanned substations.

FZW35-40.5/J1250-12.5 Outdoor High Voltage Vacuum Isolation Load Switch Product Features
1. Long lifespan:
The vacuum arc extinguishing chamber of the load switch adopts a fixed type, and only the moving contact end of the arc extinguishing chamber moves when the switch is activated. Similar domestic products adopt the overall action structure of the vacuum arc extinguishing chamber, which greatly increases the service life of this product (more than 10000 times);
2. Low circuit resistance:
When the production port is working normally, the vacuum arc extinguishing chamber is connected in parallel to the main circuit, and the vacuum arc extinguishing chamber of similar new products is connected in series to the main circuit. Compared with parallel and series, the circuit resistance is greatly reduced.
3. Good sealing performance:
The arc extinguishing chamber action mechanism of the product is installed in a sealed aluminum alloy box, effectively preventing the impact of harsh outdoor conditions on the operating components.
4. Strong corrosion resistance:
The electric operating mechanism box of the product adopts a stainless steel shell, and the exposed standard parts are made of stainless steel; The exposed metal parts are treated with hot-dip galvanizing, which enhances the corrosion resistance of the switch.
5. Diversified operational methods;
Not only electric, but also mobile phone operation adopts a pull ring structure, which can be operated by using an insulated pull rod. Specially suitable for pole mounted assembly of circuits without operational power supply.
6. Small size and heavy weight: length X width X height (1700X1400X1200mm); Weight 200kg
