3-phase earthing device
Ref. SS 428 91 01, SS-EN 61230Conductor clamp JK 27 and earthing clamp JK 27 V are 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 conductor clamp, insulating rods MGV, MDV/MSV and grippers JGS are used.
The conductive parts of the clamps 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 (25-50mm2) / M12 (70 mm2) screw connection. For the 95-120 mm2 wire rope, the JFG 4 branch piece is used (see JK27-X-JK27V).
The don cable is made of highly flexible ESTPR-insulated copper conductor and provided with tight cable connections, which prevent moisture penetration into the cable. The sheath of the branch piece (JFG 4L) is made of insulating plastic.
