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.

3. Product environmental conditions

1. Altitude: 1000-3000 meters
2. The ambient temperature is not higher than + 40 ° C, and the minimum temperature is not lower than -35 ° C (alpine area is not lower than -40 ° C).
3 The wind speed does not exceed 34m / s.
4. The seismic intensity does not exceed 8 degrees.
5. The thickness of ice coating should not exceed 10mm.
6. Pollution-resistant products are suitable for heavily polluted areas.
7,  Not suitable for places with flammable substances, explosion danger, chemical corrosion and severe vibration.
