Product Description

Indoor 36kv High Voltage Sf6 Gas Load Break Switch

Product description

GSC-36 high/medium voltage SF6 load break switch, with a rated voltage of 12kv, 24kv or 36kv, can response and protect power system when there is an error. The switch can be either manual operation or electrical operation, and earthing function is optional. Switch fuse combination can protect the whole system.
Compact size, easy installation and free of maintainence make the switch suitable for wide applications, especially for ring main unit.  It also can work with vacuum circuit breaker to make a switchgear combination for excellent performance with favorable cost.

1.normal operating conditions

a)Ambient air temperature is not more than 40 ºC, and at 24 h closed to the average no more than 35 ºC. Minimum ambient air temperature 25 ºC.
b)The effects of sunlight can be ignored
c)No more than 3000m above sea level.
d)Ambient air is not significantly contaminated by dust, smoke, corrosive and/or flammable gases, vapors, or salt fog. If the user does not have special requirements, the manufacturer may consider that these situations do not exist.e)The humidity conditions are as follows:
--The average relative humidity measured within 24h is no more than 95%.
--The mean value of water vapor pressure measured within 24h shall not exceed 2.2kPa.
--The average monthly relative humidity should not exceed 90%.
--The average monthly water vapor pressure does not exceed 1.8kpa. In such conditions appear condensation occasionally.
f) The vibration or ground motion from the outside of the switching equipment and the control equipment has no obvious relationship with the normal operation mode of the equipment. If the user has no special requirements, the manufacturer may not consider these situations.
