Earthing & Short-circuiting Kit for High Voltage Power Systems | 18.7kA/s | 20kA/s

Earthing & Short-Circuiting Kit for High Voltage Power Systems 18.7kA/s

PORTABLE EARTH KITS

Earthing kits are components that establish both direct and indirect connections, through connecting links or cables, between earthing and short-circuiting bars and the ground. These Kits range from overhead line clamps, low-voltage switchboard jumper clamps and live-end and earth-end earth clamps.

Pfisterer’s earthing and short-circuiting kits are vital while working on electrical switchgear because they ensure user safety while also safeguarding the switchgear. When earthing and connecting a temporary short-circuit-proof link to switchgear components, use only high-quality equipment.

Earthing and Short-circuiting devices have been manufactured by Pfisterer for decades, ensuring electrical safety, dependability and quality that are in accordance with IEC 61230 standards.
