3M LVI-1/x Scotchcast Resin Cable Joints (470W Resin) – Armoured XLPE SWA Cables

3M Scotchcast Resin Cable Joints LVI-1/x Series (470W Resin) - Armoured XLPE SWA Cables

3M Scotchcast Resin Cable Joints LVI-1/x Series (470W Resin) – Armoured XLPE SWA Cables


3M LVI-1/x Scotchcast resin cable joint kits are used for jointing multi-core steel wire armoured (SWA) polymeric low voltage power cables, including XLPE wire armoured and EPR wire braided cables (600/1000 volts).

3M LVI-1 Scotchcast cable joints incorporate electrical insulation and mechanical protection and are compatible with both compression (crimp) or mechanical shearbolt connectors for conductor jointing of copper or aluminium cores.

Jointing kits can be used for indoor and outdoor, underground direct burial and submerged applications in non-hazardous area locations – straight and transition joints (jointing dissimilar cable insulation types) including EPR, XLPE and PILC cable are available utilising Scotchcast resins.

3M Scotchcast hazardous area cable joints are available for jointing power, pilot and instrumentation cables in Zone 1 and Zone 2 potentially explosive atmospheres – hydrocarbon resistant and Cold Shrink types of cable joint are available for hazardous area locations (HAZLOC).

BS5467 & BS6724 Power & Wiring Cables & Joints

3M Scotchcast cable joints are suitable for both BS5467 and BS6724 cables in both direct burial (underground cable trench) or free air installations onto cable containment – however should the joints be installed onto BS6724 cables where a fire would create dense smoke and toxic fumes causing a major threat to both life and equipment a zero halogen cable joint should be installed.

3M Scotchcast Resin Cable Joints

Scotchcast Joints – Safe & Reliable Resins

3M Scotchcast LVI-1/x resin inline or straight cable joint kits are supplied with a one part translucent mould body for simple and easy handling. Distances inside the cable joint body can be checked easily.

All necessary dimensions, including kit application range, cable preparation are given in the detailed 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 delivered in a two chamber bag with integrated spout and aluminium Guard Bag for protection of the resin against humidity.

The re-openable seam and integrated spout with a membrane provides a 3M Closed, Mixing and Pouring (pictured) cable jointing system.

After the seam of the two chamber bag is opened, the Scotchcast resin components can be mixed.

To pour the resin into the mould body, the spout is connected with the dome by turning 180°.

While turning, the membrane is cut open to pour the resin. The 3M Closed Mixing and Pouring System provides resin handling without any skin contact – for protection against pollution, a closure cap is applied onto the dome. After curing, the remaining joint resin in the bag can be disposed as household waste.

3M Scotchcast 470W Resin

Scotchcast 470W resin is in compliance with EU regulation 1907/2007/EC (REACH) and has a shelf life of at least 36 months when stored between 10°C and 40°C with a humidity level < 75 % in the originally sealed bag.

The expiration date of each product appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, it is the responsibility of the user to determine applicability of the resin.

Complete range of Scotchcast Resins are available to protect and encapsulate cable joints operating at LV MV HV including zero halogen, fire resistant, hydrocarbon resistant and seawater resistant types.
