JN15 Earthing Switch
Description
The JN15 earthing switch is designed and manufactured based on the advanced new techniques of both domestic and overseas. It consists of such main components as the base, supporting insulator, main axis, spring, fixed and moving contact. As a highly reliable earthing electrical switchgear, this indoor earthing switch meets the standards IEC 62271-102: High-Voltage Switchgear and Controlgear, Part 102: Alternating Current Disconnectors and Earthing Switches. It could be applied in a power system of a rated voltage 12kV, 24kV, or 40.5kV, and a rated current of 50Hz or 60Hz and provide reliable earthing protection to the system.
