Description

CROP parallel groove clamp 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. A further area of application is the damping of vibrations as PG-clamps are used to attach the bretelle damper. PG-clamps can be used as a jumper spacer and in that case they are connected by a steel bar. It is also possible to connect two conductors of different sizes by using reduction tubes. If conductors made of different materials are to be connected this can be done by using bimetallic tubes.
