Conductor clamp JFS 21 is connected to hook JKS and JKR. To operate the clamp, insulating rods MGV, MDV/MSV and gripper JGS are used.
The conductive parts of the clamp are made of hot-pressed electrolytic copper. Steel parts are made of stainless steel. The conductor clamp is equipped with stainless steel disk washers, which provide a constant contact pressure. The ESTPR-insulated copper conductor is provided with tight cable connections, which prevent moisture ingress into the cable. The cable is crimped to the earthing device. Cable lugs JLA 33 are made of hot-pressed electrolytic copper. JLA is connected to fixed earthing connectors, JVF and JBF.
