The PBwel range of equipment for use on the Rail track and the OHL network has been specifically designed with the UK Rail Industry and has proven track record of many decades service. As well as supplying a standard range of approved equipment, PBwel also can design new solutions for any Rail Portable Earthing requirement.
The Interlocked Long Blue Earth from PBwel has been designed to solve a pressing need in the Rail Industry.
The equipment has been specially enhanced 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 before 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 PBwel can provide up to 20 combinations, this is to deter ‘master keys’ being used to fool the system.
This interlocked long blue 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 a secure location. All components are plated to provide adequate protection on site.
Interconnecting Leads are made of 50sqmm multi-stranded Aluminium with Aluminium palm type compression terminations and blue Arctic-grade PVC insulation. The S9BI Line End clamp is made from Aluminium alloy and stainless-steel fasteners.
Insulated Operating Poles are glassed fibre insulating poles with open weave handgrips bonded to the lower pole section. Available in standard 4ft (1.22 metre) sections with machined joints to provide rigid assembly by double-sided snap action, spring-loaded locking device. The S9D type light-alloy operating socket should be fitted; the socket is then used to rotate the Line End clamp’s operating screw, to secure to the line.
