Overview:
GW (12)/630-20 outdoor AC high voltage isolate switch (hereinafter referred to as isolating switches) are our company on the basis of the original product, and is designed to update, make the structure more reasonable and more reliable operation. This switch applies to the frequency of 50Hz and of rated voltages up to 12KV or 40.5KV power system. Switching device in outdoor high-voltage power distribution equipment lines, for line voltage, open circuit when no load, pollution-proof isolation switch appears in the running of these pollution problems. Switching three-electrode interaction, well over the same period, and a striking arc devices, equipped with spring, the fast opening. The switches are compared to similar products, breaking, making small inductance and capacitance current advantages.
The use of environmental conditions:
1, ambient air temperature maximum + 40 degree, minimum-25 degree, temperature does not exceed 32K;
2, altitude: 3000m and the following areas;
3, wind pressure does not exceed 700P. (The equivalent wind speed 34m/s);
4, air pollution levels: 4.1 of article IV of the GB5582 level;
5, ice coating thickness does not exceed 10MM.
