Product Description

Supplier Electric High Voltage 36kv Sf6 Gas Load Break Switch Lbs 

Product Description
GSC-36 is an indoor high-voltage SF6 load switch with a rated voltage of 36kV/40.5kV. It uses SF6 gas as the arc extinguishing and insulation medium, including three contactors for switch and grounding. It has the characteristics of small volume, easy installation and operation, and strong adaptability to the environment. Indoor high-voltage SF6 load switch GSC-36 and SF6 load switch with fuse combination GSC-36 can protect and control the electrical equipment of power supply substations and substations, especially suitable for ring main cabinets, cable branch cabinets, and distribution switch stations.
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.
 

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.
