Parallel groove clamps are mainly used for transmitting current between the interconnected conductors, for example for connection loops on terminal poles or tapping off bus-bars to equipment on substations. From this function it is therefore obvious that the electrical conducting properties and the corrosion resistance are the main factors for consideration in the design. Besides this main area of application parallel groove clamps are also used for safety loops and therefore they must provide an adequate mechanical holding strength. If conductors made of different materials are to be connected this can be done by using bimetallic tubes. This range of connectors is designed to connect two paralell conductors in order to do a derivation of a secondary conductor, or to close a loop of one conductor to fit it on an insulator. These connectors are composed of two parts : Upper body and lower body, they have two paralell grooves to receive the conductor(s).One, two or three bolts are passing throught the bodies between the grooves. In aluminium clamps, the two bodies are made out of high strength aluminium alloy. In copper clamps, the bodies are made out of high strength electrolitic copper. In bimetallic clamps, the two bodies are made out groove is made with allumiunm alloy and welded by hot forged bimetallic sheet . The bolts are made out of hard steel (8.8) and Dacromatized. To warranty a reliable tightening, a pressure pad and a spring washer are inserted under the bolt head.
