rn 3M™ Scotchcast economy resin joint is our no nonsense resin joint replacing our BK joints. Comprising of a two part shell and our standard close mix two part resin bag. Scotch® 23 Self Amalgamating tape is used to seal the crotch of the cable. The cable cores are then cut to length. If necessary the joint shell is large enough to accommodate the crossing of phase cores.

rn
rn The insulation is then removed and connectors are installed. A number of our kits come complete with connectors for ease of selection. However any connector can be used providing they suit the requirements of the cable and fit dimensionally within our joint. Scotch® 23 Self Amalgamating tape is used to over tape the connectors. Layers are applied tightly around each connector over lapping onto the primary insulation on each side of the connector position. For cables up to 1kV, 3 half lap layers are applied.

rn Ideal For General Purpose Street Lighting & Service Cable Jointing
rn
rn To avoid awkward manipulation of armour wires while trying to fit worm drive clips over support rings, we have chosen to use constant force springs as our preferred earthing method – a quick and easy solution requiring the minimum of fuss and no extra tooling. Scotch® 23 Self Amalgamating tape is used to over tape the constant force springs. Ensure it is applied in the same direction as the constant force spring.
rn
rn  
rn
rn The cable sheath is then abraded to remove any contaminants to ensure the resin bonds to the cable jacket. Unlike our standard and premium joints, the economy range utilises a traditional two part mould shell that requires the cutting of the stepped ends to fit the required cable diameter. Scotch® 23 Self Amalgamating tape is used to seal the conical ends of the mould to the cable sheath.
rn
rn  
rn
rn Our resin compound has been re-developed to comply with EU environmental and user safety regulation changes, and are all REACH & ROHS compliant. When pouring the resin into the mould ensure the gloves provided are worn to avoid potential skin contact. The Scotchcast Standard resin joints are ideal for general purpose street lighting & service cable jointing.
