For The UK Rail Industry
Interlocked Long Blue Earth Clamps | Network Rail Approved By PBwel
The PBwel range of LV MVH HV electrical safety 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 and customised solutions for any Rail Portable Earthing requirement.
This interlocked Long Blue Earth Clamps are for providing temporary earth bonds between overhead catenary or contact conductors and earthed rail sections or recognised earthing points. The Long Blues have 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 earthing clamps, and PBwel can provide up to 20 combinations, this is to deter ‘master keys’ being used to fool the system.
This interlocked Long Blues are 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.

Interlocked Long Blue Earth Clamp: specially enhanced to address the potentially fatal procedure of removing the equipment in the incorrect order of use
Long Earths
Long Blues are generally 8 metre in length. However, any earth lead length can be provided if specified for non-Network Rail work. Although an S9B to J117-D configuration is standard, Long Blues can also be supplied with CE62 Clamps (not Network Rail approved).
Interlock Earths
Interlocked Earths provide the same connections as a regular Long Blue; however, the earthing clamps utilise a lock-and-key system where the Earth End is removed using the Line End. This ensures that Engineers do not accidentally disrupt the path to earth prematurely as the Earth End can only be removed by using the Line End clamp.
Line end clamps are available in an S9B style or CE5 style (designated S9Bi and CE5i respectively).
