Product Details
Outdoor AC high voltage disconnector GW4 series are outdoor HV apparatus of three-phase 50Hz in electrical power system of rated voltage 126-252kV, acting as switching operation under no-load condition as well as electrical separating between electrical apparatus being tested and live circuit.
The product tallies with the requirements of GB1985 and IEC62271-102.
Main Features:
1. Simple in structure, superior in characteristics and reliable in operation;
2. High reliability by adopting self-supporting structure of contacts;
3. No need to check and adjust during operation, contact pressure does not change consistantly;
4. Better in self-cleaning capacity;
5. Touching pressure of contact is increased automati-cally when passing through short circuit current;
6. Superior in anti-rust features by adopting the design of anti-corrosion;
7. Better in the stability of structure for whole body;
8. Simple in assembling, easy in adjusting.
