Product Description

1. GW4 type 12kv, 24kv, 40.5kv, 66kv, 72.5kv, 126kv outdoor AC high voltage disconnected switch

 

GW4-12, 24, 40.5, 66, 72.5, 126 series outdoor AC high voltage disconnected switch (hereinafter referred to as disconnected switch). It is suitable for power systems with a frequency of 50HZ and a rated voltage of 12,24,40.5,66,72.5,126. The anti-fouling disconnected switch can meet the requirements of users in heavily polluted areas, it can effectively solve the problem of pollution during the operation of the disconnected switch. The disconnected switch and the attached grounding switch are each equipped with an independent operating mechanism. In order to ensure the correct operation sequence between the disconnected switch and the grounding switch, this product is equipped with a mechanism interlocking device. The 35-110KV grounding switch is divided into Type I and II, 15 / 220KV is type II. The dynamic thermal stability of the type II grounding switch is the same as that of the disconnected switch.

2. product  specifications:

1. According to the presence or absence of a grounding switch, it is divided into: ungrounded, single grounded, double grounded
2. Divided according to the area of use: ordinary type, anti-fouling type. Features of this series of disconnectors:
(1) The electrical connection terminal is transitioned through a soft connection, and the conductive contact is reliable;
(2) The ground knife adopts an external closing arrangement to ensure the reliable insulation distance of the ground knife to the other live end during the closing process;
(3) GW4-220 is equipped with a folding ground knife to reduce the space outside the ground knife.
