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 grip locators 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 cable lug and M8 (25-50mm2) / M12 (70-95 mm2) screw connection. For the 95 mm2 cable, the JFG 4 connector is used (see JK27-X-JLA33).
The cable is made of highly flexible ESTPR-insulated copper conductor and provided with tight cable connections, which prevents moisture penetration into the cable.
The JLA 33 cable lug is made of hot-pressed electrolytic copper, the connector (JFG 4L) sheath is made of insulating plastic. JLA 33 is connected to fixed connectors to earth, JVF and JBF.
