JN15-24/31.5-210 High Voltage Earthing Switch 3 Pole Indoor AC 24KV for MV Switchgear

JN15-12kv/24kv(40.5kv) Indoor AC High Voltage Earthing Switch

Product Introduction

The JN15 series indoor HV earthing switch incorporates advanced domestic and international technologies. Compliant with GB 1985 AC HV disconnect switch and earth switch standards, as well as IEC62271-102 standards. Designed for power systems rated below 12/24/40.5kV at 50/60Hz AC, this apparatus provides earthing protection for various types of HV switchgear. The complete earthing switch consists of a base, supporting insulator, main axis, main blade, fast spring, and fixed/moving contacts. Optional electronic display available upon request.
