The 3M resin pressure System is comprised of several components that are used for constructing splices jackets on medium voltage power cables for harsh environments. 3M Scotchcast Electrical Insulating Resin 4 is a key component of the system, which can be used as the primary insulation for shielded and non-shielded splices rated up to 8kV.

The resin is a two-part epoxy, packaged in a special Unipak container that provides the exact mixing ratio for making a strong, dependable and long-lasting splice or splice jacket. The versatile resin system accommodates a variety of splice configurations and cables.

A resin pressure system splice is suitable for submerged locations (e.g. manholes and vaults). Underground direct burial and aerial applications.
