3M Scotchcast resin (470W) cable joints are designed to cable joint multi-core armoured (SWA or GSWB), polymeric (XLPE EPR) low voltage power cables.
3M cable joints provide electrical insulation and mechanical protection with either compression or mechanical connectors.
3M LVI-1 power cable joints have now replaced the 3M LA range of cable joints.
3M LVI-1 Resin Cable Joint Kits - Maximum Cable ODs (mm)
3.3kV Power Cable Jointing
Up-rating 3M Scotchcast resin cable joints for connecting unscreened 3.3kV power cables is achieved by increasing the Scotch 23 self-amalgamating tape to 5 half-lapped layers over each connector.
For smaller cables where pre-insulated connectors are used, it is not required to cover the connectors with Scotch 23 tape.

3M LVI-1 Resin Cable Joints - Description
3M Scotchcast LVI-1 resin inline cable joints are delivered with a one part translucent mould body for simple and easy handling by cable jointers.
Distances inside the joint body can be checked easily. All necessary dimensions, such as cable application range, are covered in the cable jointing instruction.
The two foam sealing elements can be adapted to the required cable diameter by removing the pre-cut adapter rings.
Scotchcast resin 470W is supplied in two chamber bag with integrated spout and aluminium guard bag for protection against humidity.
The re-openable seam and integrated spout with membrane provides a unique Closed Mixing and Pouring Cable Joint System.
After the seam of the two chamber resin bag is opened, the resin components can be mixed. To pour the cable jointing resin into the mould body, the spout is connected with the dome by turning 180 degrees.
While turning, the membrane is cut open to pour the Scotchcast 470W resin into the cable joint - the Closed Mixing and Pouring Systems provides resin handling without any skin contact by cable jointers.
