Line clamp JFS 21 is for connection to hooks JKS and JKR. Insulating poles MGV, MDV/MSV and operating socket JGS are used to operate the line clamps. The line clamps conducting parts are made of hot pressed electrolytic copper. Steel components are made of stainless steel. The line clamps have stainless steel spring washers to ensure constant contact pressure. The earthing cable, made up of a highly flexible ESTPR-insulated copper strands, has sealed cable connections, which prevent humidity from penetrating the cable. The earthing cable is connected by compression to the earthing device. Earth clamp JK 153 is used on steel constructions with a thickness up to 20 mm and is also approved for painted surfaces. The screw on this clamp is insulated.
