3-phase earthing device
Ref. SS 428 91 01, SS-EN 61230
Conductor clamp JK 27 is connected to ball bolt Ø 20, Ø 25, Ø 30, T-bolt, rail 1-25 mm, rope/pipe Ø 6-25 mm. To operate the clamp, insulating rods MGV, MDV/MSV and grippers JGS are used. The conductive parts of the clamp are made of aluminum bronze. Steel parts are made of stainless steel. The wire rope is connected to the clamp with a cable lug and M8 (25-50 mm2) / M12 (70-95 mm2) screw connection. 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 JK153 is used on steel structures with material thickness max. 20 mm and are also approved for painted surfaces. The screw on this clamp is provided with insulation to prevent current penetration.
