![]() Similarly mechanical style conductor connectors are commonly used to joint conductors with divergent cross section areas – often called “reducer connectors” the shearbolt type connectors permits the “step-down” jointing of cables within the range accommodation of the connector. Typical applications could involve the transition cable jointing of BS5467 XLPE SWA copper conductor to existing imperial PILC SWA aluminium conductor cables in an underground application (or direct burial) in a cable trench.ģ.3kV cable joints utilising heat shrink technology and mechanical shearbolt connectors are available for the jointing of power cables up to 3.3kV in accordance with IEC 60228 and IEC 60502 – this includes the cable jointing of circular to sectoral conductors. Thorne & Derrick can make recommendations to overcome the potential problems encountered when cable jointing aluminium to copper cables and provide guidance on best practice to avoid potential corrosion problems within resin cable joints up to 3.3kV. What To Consider When Jointing Cables With Various Types Of ConductorĪ common question posed by LV cable jointers concerns the conductor jointing of dissimilar metals or core construction in underground cable joints. ![]()
