3M Cable Joints – Y Branch Cable Joints (Scotchcast Resin 40)
cABLE JOINTS FOR LV POWER CABLES
3M Y branch resin cable joint kits 92-NBB x are designed to be used for 1-core up to 5-core non shielded (unarmoured), polymeric, low voltage energy cables.
3M Y branch 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.
3M Scotchcast hazardous area cable joints are available for jointing power, pilot and instrumentation cables in Zone 1 and Zone 2 potentially explosive atmospheres.
3M Cable Joints – Y Branch Cable Joints (Scotchcast Resin 40) features
- 3M Scotchcast 40 resin is supplied in transparent two chamber bags with integrated Closed Mixing and Pouring (CMP) system
- Two part (upper and lower) mould shelves with Snap Fit closing system for quick and easy handling
- Transparent Mould Body for easy control of connector distances in the joint
- Pre cut foam sealing elements to provide reliable sealing to the Mould Body without tooling for all cable application diameters
- Closure cap to prevent any pollution
3m Cable Joint description – Y branch cable joints
3M Y branch 92-NBB 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 40 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 40 Resin
Scotchcast 40 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.
