Cable Joint Application Notes – 3M Scotchcast cable joints are suitable to connect, repair and joint DC solar cables – this includes solar cables with XLPE insulation and halogen-free polyolefine outer sheath and semi-rigid Class 2 aluminium conductors to the following standards. The low voltage power distribution cable is suitable for direct buried installations.
3M straight connection joints provide excellent electrical insulation and mechanical protection – high weathering, tear, abrasion and impact resistant DC solar cable joints for unamoured and armoured (AWA SWA) type power cables.
