The cable sheath protection grounding box contains cable sheath protector, connecting copper bar, copper terminal and so on, which is used for the protective grounding of cable sheath. The main protector adopts ZnO cable sheath protector, and the sealing structure adopts silicone rubber seal to achieve higher sealing and waterproofing requirements. All of them are cast aluminum or stainless steel shell, the conductor connector is plated with tin copper, and the bolt is pressed, and the installation is simple. It is convenient for the cable metal sheath to be removed from the protector during the preventive test. The protective grounding box can be installed in outdoor operation without any abnormal weather. The cable sheath protection grounding box is divided into single phase grounding protection box, three-phase three wire grounding protection box (usually referred to as grounding protection box), and three-phase six wire grounding protection box.
