JK80-JLA30 (JSFD)
JK81-JLA30 (JSCD)
3-phase earthing device
Ref. SS 428 91 01, SS-EN 61230
Conductor clamps JK 80 and JK 81 are connected to a ball stud. 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 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 30 is made of hot-pressed electrolytic copper. JLA is connected to fixed connectors to earth, JVF and JBF.
