Grounding Clamp. Pins and Ball-Socket Clamps for Temporary Grounding

Transcription

1 Grounding Clamp Pins and Ball-Socket Clamps for Temporary Grounding Pins and Ball-Socket Clamps have been designed to solve several temporary grounding situations, where the physical space or the contact surfaces are limited. In cubicles, mainly those with rectangular profile busbars, where the conventional grounding clamps dimensions make them unfeasible to use, the ball-socket clamp is suitable due to its versatile conception and easy operation. This clamp is quite useful in electrical systems, such as: - Cubicles; - Indoor and outdoor substations; - Rolling bridge; - ive line vehicles; - Painted Transmission ines Structures, where there is no electrical contact with the conventional clamps; page 332

3 Pin-Ball for Temporary Grounding Points The Pin-Balls are intended for permanent installation on busbars, on busbars joints, on terminals or on any other parts of the electrical system, establishing the points required for the suitable grounding of such systems. Therefore, it is recommended to order it in sufficient quantities for these applications. In order to better suit customer requirements, Pin-Balls are available in 7 different dimensions and positions of the connection ball.
