JK80-X-JLA34 (JSEK-FM)
JK81-X-JLA34 (JSEK-CM)
3-phase earthing device
Ref. SS 428 91 01, SS-EN 61230
The conductor clamps JK 80 and JK 81 are connected on a ball stud. 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 conductor clamp is equipped with stainless steel disk washers, which provide a constant contact pressure. The wire rope is crimped to the earthing device. The cable is made of highly flexible ESTPR-insulated copper conductor and provided with tight cable connections, which prevents moisture penetration into the cable. Cable lug JLA 34 and branch piece JFG 4 are made of hot-pressed electrolytic copper, handle nut of stainless steel. JLA is connected to fixed connectors to earth, JVF and JBF.
