AG’s Cable joining Resin kits provide a robust, watertight and long-lasting solution for straight-through electrical cable joints. Designed for professional electrical installers, these kits deliver excellent electrical insulation, mechanical protection and environmental sealing for low-voltage cable connections in demanding conditions.

Cast resin jointing remains one of the most trusted methods for cable repair and joining, particularly where joints are exposed to moisture, ground movement, vibration or harsh outdoor environments.

Key Features & Benefits

• Straight-Through Cable Jointing
  Designed to securely join two cable ends inline, forming a fully encapsulated and insulated connection.

• Cast Polyurethane Resin System
  The two-part resin cures to form a solid, void-free mass that provides outstanding electrical insulation and mechanical strength.

• Watertight & Weatherproof
  Once cured, the resin joint offers excellent longitudinal and transverse water sealing, making it suitable for underground, outdoor and wet installations.

• Transparent Moulding Shells
  Impact-resistant clear shells allow visual inspection during installation to confirm complete resin fill before curing.

• Safe & Simple Installation
  The resin mixing and pouring system is designed to minimise air pockets, helping installers achieve consistent, reliable results every time.

• Complete Ready-to-Use Kit
  Supplied with all required components for installation, reducing downtime and eliminating the need for additional accessories.

Typical Applications

Cast resin cable joint kits are widely used across a range of electrical installations, including:

• Low-voltage power cable joining and repair

• Underground electrical services

• Outdoor lighting cable installations exposed to moisture

• Industrial and commercial electrical systems

• Infrastructure, utilities and maintenance work

These kits are suitable for use with many common cable insulation types, including PVC, XLPE, PE and EPR.

What’s Included in a kit?

Each resin joint kit is supplied as a complete system and typically includes:

• Two-part polyurethane casting resin with mixing/pouring system

• Durable transparent moulding shells

• Insulation tape and surface preparation materials

• Protective gloves

• Step-by-step installation instructions

(Connectors not included unless otherwise stated.)

Why Choose Cable Joining Resin Kits?

Compared to alternative jointing methods, cast resin cable joints provide superior durability, long-term sealing and mechanical protection. Once cured, the joint becomes a solid, maintenance-free connection that performs reliably over time, even in harsh or high-risk environments.

These kits are ideal for installers who need a dependable, professional-grade solution for critical cable joining applications.
