Guang'an outdoor isolation switch manufacturers GW4-35 / 630 single-ground high-voltage isolation switch

Guang'an outdoor isolation switch manufacturers GW4-35 / 630 single-ground high-voltage isolation switch disconnectors type rod series switch with surge arresters, silicone rubber, I plant a series of questions for the existence of the original GW4 switch, according to current national and international standards modified design from a new switch. Switch itself with earth switch can effectively prevent the "live hang ground and closing with the ground" and other misuse, operators are no longer separate ground wire. The product is its excellent electrical and mechanical properties, is the current level of outdoor switch 10-35KV updated products. 2, the scope of the switching circuit for three-wire AC 50Hz, for there is no voltage division together with the load circuits. The basic use of the following conditions: (1) the altitude does not exceed 3000m, ambient temperature is not lower than -40 ℃ not higher than + 40 ℃. (2) wind speed of not more than 35mm / S, the earthquake intensity does not exceed 8 degrees. (3) adapted to the big cities, mining and other polluted areas nearby. (4) have not adapted to fire and explosion hazard, there is severe vibration and impulsive, have serious corrosion of metals and chemicals place insulation materials. Isolation switch from the base insulating pillars and conductive parts and operating mechanism and other components. Each pole has two pillars, each pillar, each equipped with a conductive upper knife. Two parts in contact with the knife contacts the middle of the two pillars. Each equipped with the lower strut bearing sleeve, driven actuator, can make the knife horizontally rotated 90 degrees, so as to achieve the requirements of sub-closing. Isolation switch is unipolar, but also through a link can be linked together into a three-pole three-pole type. Equipped with CS11 (ungrounded) CS8-6D (single ground) CS17 (double ground) type manual operating mechanism. (Can be equipped with electric mechanism needed) is easy to see from the structure introduction, this isolation switch structure is reasonable, flexible and comfortable actuator; be unipolar, but also three-pole to use, easy to install; touch also open away from large, insulated safety reliable. Also based on user needs, ungrounded or grounded or double-sided equipped with pick
