GW5-40.5 (72.5/126KV) series isolation switch

> Overview
The series of outdoor high-voltage isolating switches are three-phase AC outdoor high-voltage electrical appliances composed of three independent single poles. They are used for opening and closing circuits when the shared voltage is no load.
This series of products can be equipped with a grounding switch, which is divided into two types: single grounding and double grounding. The grounding switch is divided into type I and II according to the short-circuit current capacity it can withstand.
The basic environmental conditions for product use are as follows
The lifting height shall not exceed.
The highest ambient temperature is not higher than ℃ and the lowest ambient temperature is not lower than ℃.
The pressure does not exceed the equivalent of wind speed/.
The degree of cracking does not exceed.
The ice thickness does not exceed.
The creepage ratio of column insulators is not less than that of the ordinary type and that of the anti-pollution type, according to the "Pollution Level of External Insulation of High-Voltage Power Equipment".
The installation site should be free of flammable substances, explosion hazards, chemical corrosion and severe vibrations.
Technical Data
This series of products complies with the national standard "AC High Voltage Isolating Switch" and factory technical conditions
. The technical parameters are shown in the table
Product Structure
Series Isolating Switches Composed of three monopoles. Each single pole is composed of two rod-type pillar insulators respectively fixed on a base, with an intersection angle of . It is mainly composed of a conductive part, a pillar insulator base, a grounding switch and a manual operating mechanism. Its dimensions are shown in the table.

Conductive part
The conductive part is fixed on the upper end of the porcelain bottle and consists of left and right contact outlets and grounding Composed of static contacts.
Base
The base is composed of the base bevel gear base and the adjusting screw.
Hand operated mechanism
The hand operated mechanism is divided into three types: ungrounded, single grounded and double grounded. The mechanism is equipped with an interlocking plate to realize the interlocking between the main cutter of the isolating switch and the ground cutter. The hand-operated mechanism is equipped with an electromagnetic lock and its accessories.
