Short description Resin joint kit for polymeric or paper‑insulated single‑ or multi‑core cables. The kit includes a stepped housing and a room‑temperature curing polyurethane resin. The assembly ensures mechanical protection and reliable sealing. Compliant with CENELEC HD 623 and CEI EN 50393.

Product overview The ELCOBLOK GTU kit comprises a molded containment housing with graded cable entries to adapt to conductor diameters and an injectable or pourable polyurethane resin that cures at room temperature. Designed for branch and standard splices on low‑voltage networks up to 1.2 kV.

Applications

• Branch and inline splices on LV distribution networks (up to 1.2 kV)
• Repairs and retrofit joints for polymeric (XLPE) or paper‑impregnated cables
• Indoor and outdoor installations where mechanical protection and sealing are required

Installation Installation consists of preparing and stripping the cable ends, positioning conductors in the stepped housing, filling the chamber with the supplied polyurethane resin and allowing it to cure at ambient temperature. No special ovens are required; follow manufacturer's curing times and safety instructions.
