A Permanent Fix: A Sparky's Guide to Cable Joining & Repairs

A damaged cable on a job site can bring an entire project to a grinding halt. When you're faced with a severed underground cable or a compromised industrial line, a simple tape-up job is not a safe, compliant, or professional solution. For a permanent, waterproof, and rock-solid fix that will stand the test of time, you need a professional cable joining and repair kit.

At SCHNAP, our trusted range of Cable Joining & Repair solutions provides everything Aussie sparkies and contractors need to get critical circuits back online safely and reliably.

The Gold Standard for Underground Repairs: Resin Kits

For underground and direct-burial cable repairs, the Scotchcast resin kit is the industry standard for a reason. These all-in-one kits are the ultimate solution for a permanent, "bury-and-forget" repair.

  • How they work: The kit includes a clear plastic mould that snaps around the repaired cable joint. A two-part polyurethane resin is then mixed in its bag and poured into the mould.
  • The Result: The resin sets rock-hard, creating a completely waterproof, impact-resistant, and permanent encapsulation of the joint, providing full electrical insulation and mechanical protection.

Other Tough Repair Solutions

Our range also includes other heavy-duty options to suit various applications:

  • Fibreglass Repair Sets: A durable alternative, often used for repairing the outer mechanical sheath of a large cable, providing excellent abrasion and impact resistance.
  • PVC and Nylon Fittings: A selection of high-quality fittings for general-purpose junctions and terminations in less demanding environments.

Built for the Toughest Aussie Sites

Our cable joining and repair solutions are selected for performance in the real world, from standard residential installs to the most demanding industrial and hazardous areas. Every kit and component is designed to be tough, reliable, and compliant with Australian standards, ensuring your repair is as good as the original cable.
