The cable sheath protection grounding box is suitable for high-voltage power cable systems, which can realize the crossoveland interconnection between the metal sheaths of three-phase high-voltage cables, protect the outer sheath insulation of high.voltage cables from overvoltage damage, and effectively improve the power supply of power cable lines. reliability.The overall structure of the product is simple and reliable in sealing. The outer shell and the main internal structure are weldedwith stainless steel, The insulating parts are treated with moisture-proof, The qrounding connection row is made of copper withexcellent conductivity, According to the reguirements, all assemblies are compressed by bolts, which is easy to install andfacilitates the disconnection between the metal sheath of the cable and the ground wire during the preventive testThe grounding box can be installed outdoors or in cable trenches, and is not affected by various abnormal climates.
Tech DataThe workina principle of the protector, The core component of the product is the cable sheath protector, and the protector iscomposed of an oxidation resistance sheet with excellent nonlinearity.ln the normal working state, the resistance piece hasa high resistance value, and when the overvoltage wave is immersed, the resistance piece has a low resistance value. Evenif a large current flows, the voltage value across the protector is stilimited within the allowable range.lt effectively protectsthe insulation of the outer sheath of the cable and prevents it from being damaged by overvoltage.
