Constant Force Springs

3M Constant Force Springs are a range of solderless connections for earthing or grounding use on:
• Lead and aluminium cable sheaths
• Cable screening tapes or wires
• Steel or aluminium armour wires
The spring is easily applied by rolling onto the cable core or outside diameter, whereupon it continues to exert a constant radial pressure.

Applications:
– For power, control or telecom cables
– For use on lead or aluminium sheaths and copper screened cables
