Our Railway Equipment Shorting Straps are used to short the positive and the negative circuit of a D.C. feeder section. Each short circuiting strap consists of three J117 rail clamps fitted with suitably rated interconnecting flexible copper leads. The clamps are constructed from steel and are zinc-galvanised to provide protection from the site atmospheres. Secure location of both ‘flat-bottomed’ and ‘bull-head’ rail types are provided by a hardened tip above the rail and a grooved block beneath the rail. The hardened tip fits into the operating screw with an insulating bush to ensure that the correct contact path is made.The grooved block fits directly on top of the copper busbar ensuring a very low contact resistance. The busbar sits upon a stack of disc spring washers, which should be fully compressed when the clamp is applied. These washers apply a pre-loaded pressure upon the rail in order to maintain firm contact.
