3-phase earthing device
Ref. SS-EN 61230
Earthing device JKP250-X1-JK23H is intended for earthing of cables to high-voltage cable cabinets with touch-proof cable terminations 250 A. The system makes it possible to earth cable terminations without touching them with your hands!
Conductor clamp JKP is connected to the E-connector as well as to the touch-proof termination. To operate the clamp, insulating rods MGV, MDV/MSV and pliers DSG 65 are used. The conductive parts of the clamp are made of copper. Sheath made of insulated plastic.
The wire rope is connected to the clamp with a cable lug. The cable is made of highly flexible ESTPR-insulated copper conductor and provided with tight cable connections, which prevents moisture penetration into the cable. Earth clamp JK 23H is intended for connection to ball bolt Ø 20 mm, T-bolt, rail 1 – 20 mm, rope/pipe Ø 6 – 20 mm.
