HEAVY-DUTY AND WATER-PROOF LINK BOXES FOR CROSS BONDING OF EXTRA HIGH VOLTAGE CABLE SYSTEMS

摘要

The invention relates to a heavy-duty and water- proof link box (100) for cross bonding of metallic sheathes of extra high voltage cable system consisting domed rivet nuts (12) and a sealing gasket (3) which provide sealed and tight connection between enclosure body (1) and enclosure cover (2) and prevent ingress of water or dust into link box (100) even when it submerged in water and protect the integrity of link box (100) when internal arc fault occurs and adjustable sealing plugs (4) which provide sealing for cable gland (14) and coaxial bonding and earthing cables (18, 19) and act as an interface between cable gland (14) and coaxial bonding cables (18) / earthing cable (19) for water-proof penetration of coaxial bonding cables (18) / earthing cable (19) into enclosure body (1) and coaxial cable fixing clamps (5) and cable end fixing clamps (6) for tightly fixing and separating inner conductor (18A) and wire screen (18B) of coaxial bonding cables (18) and single cable fixing clamp (7) for fixing earthing cable (19).
