Indoor high voltage AC grounding switch JN22B 40.5KV 31.5KV for switchgear from JUCRO Electric
♦ Main use
JN22B-40.5/31.5 indoor high voltage grounding switch (hereinafter referred to as grounding switch) is a new product developed by the company. Its performance meets the requirements of national standard GB1985-2004 "AC high-voltage isolating switch and grounding switch" and IEC62271-102:2002. It is applicable to three-phase rated voltage 40.5kV, AC 50Hz power system, and KYN61-40.5 high voltage switch. Cabinets and other high-voltage switchgears are used together as a grounding protection for high-voltage electrical equipment maintenance.
The JN22B-40.5/31.5 indoor high voltage grounding switch is improved on the basis of the above grounding switch. The structure is simple and compact, the performance is consistent, and it is easy to operate at a small angle.As with the JN15-12 series, JN15-12 connections and transmissions are available.
♦Using environmental conditions
