Reliable Waterproof Cable Joining for Professional Installations
The CABAC Cast Resin Straight Through Cable Joint GTA5 provides a dependable solution for joining and repairing single and multi-core telephone, signal, and low voltage power cables with an outer diameter range of 26–39mm. Designed for professional electrical applications, this cable joint delivers long-lasting protection against moisture, dirt, and harsh environmental conditions.
With a compact watertight design and high electrical insulating properties, the GTA5 cable joint is suitable for installations where cable reliability is critical. It can be used for underground cable networks, cable trays, rail installations, and water-submerged environments, helping electricians and contractors complete secure cable connections in demanding conditions.
Durable Polyurethane Resin Protection for Long-Term Performance
The CABAC cast resin system uses a specially formulated unfilled polyurethane resin that provides excellent adhesion to various cable materials. Unlike rigid epoxy resins that may experience stress cracking, the flexible properties of polyurethane resin allow better stress equalisation caused by differences in thermal expansion between cable components.
The resin system provides strong mechanical protection while maintaining reliable electrical insulation. Its easy visual inspection before and during resin pouring helps installers achieve a consistent, void-free fill for improved joint performance.
The GTA5 cable joint complies with VDE standards, ensuring it meets recognised requirements for quality and safety in cable joining applications. It is also designed for convenient storage, with a guaranteed shelf life of up to three years when stored at recommended temperatures.
Trade-Friendly Design for Efficient Cable Repairs
Built for electricians and contractors, the CABAC Cast Resin Straight Through Cable Joint includes practical installation features that simplify cable joining tasks. Snap-lock components and pre-shaped cut-offs allow quick sealing around cables, while pouring spouts assist with efficient resin filling.
This cable joint is ideal for repair work, new installations, and maintenance projects where reliable cable protection is required. Available through iSupply Electrical, trades can access quality CABAC electrical accessories with competitive pricing and fast delivery options across Australia.
