Interlock Earth

The Interlock Earth from PBwel

The Long Blue Interlock Earth from PBwel has been designed to solve a pressing need in the Rail Industry.

The equipment has been specially enhanced in order to address the potentially fatal procedure of removing the equipment in the incorrect order of use. To ensure that the Line End clamp is removed prior to the Earth End clamp, it incorporates a special key which must be used to remove the Earth End clamp. The tamper-proof lock arrangement is an integral part of both clamps and P&B Weir can provide up to 20 combinations. This is to deter ‘master keys’ being used to fool the system.

This interlock earth is for providing temporary earth bonds between overhead catenary or contact conductors and earthed rail sections or recognised earthing points.

The CE63 (J117-NSE) Earth End clamp is a steel fabricated clamp for application to all rail types, steel framework and earthing points. The clamp is fitted with disc springs to ensure secure location. All components are plated to provide adequate protection on site.
