Ball Pin and Ball Shell Clamp

Ball Pins and Shell-Ball Clamps for Temporary Grounding

The ball-shell pin and clamp have been developed to solve numerous temporary grounding situations where physical space or contact surfaces are limited.

In cubicles, especially with rectangular busbars, where conventional earthing clamps have dimensions that make their use unfeasible, the ball-shell clamp stands out due to its versatile design and ease of operation.

This clamp is in great demand in electrical installations such as:
– cubicles;
– sheltered and weathered substations;
– overhead cranes;
– live line vehicles;
– painted transmission line structures where optimum electrical contact cannot be achieved with conventional clamps.

Ball pins are intended for permanent installation in busbars, busbar junctions, terminals or other parts of the electrical installation, establishing the necessary points for proper temporary grounding. It is therefore recommended that they be purchased in sufficient quantities for this use.

To better suit users’ needs, they are available in seven different lengths and in the position of the connecting ball.
