3M ScotchcastTM constant force springs are manufactured from anti-magnetic, sprung 301/302 stainless steel and suitable for a range of solderless mechanical earthing or grounding applications:
- Cable screening connections on Medium (MV) and High Voltage (HV) cables
- Lead (Pb) or corrugated aluminium (CAS) sheath earthing
- Earthing of steel (SWA) or aluminium (AWA) armour wires at any voltage
The 3M force springs are easily applied by rolling onto the material to be earthed, exerting a constant pressure with the cable, even under load conditions.
