Cable Joints
Heat Shrink Kits or submersible pump kits from Radiform are also suitable for above ground LV cable joints. Resin Kits from HellermannTyton utilise a long shelf life polyurethane resin and feature a safe filling system. Wrap Around adhesive lined heat shrink from Radiform allows cable sheath repairs without cutting cables, they are also useful when re-entry to a cable joint may required, rated to 1kV.

Submersible Heat Shrink Cable Joints
Terminating or splicing low-voltage cables in wet, buried, or saturated settings introduces severe engineering risks, as standard connection covers lack the sealing capacity to block continuous moisture tracking. Our high-performance Radiform Submersible Pump and Heat Shrink Kits completely overcome these vulnerabilities by utilizing heavy-duty cross-linked polyolefin sleeves lined with a thick layer of internal hot-melt adhesive that flows into wire gaps under heat to create a permanent, hermetic barrier. Specifically engineered to maintain absolute circuit isolation under permanent underwater submersion, these professional-grade heat shrink joint kits are also highly versatile and perfectly suited for implementing reliable above-ground low-voltage cable joints on commercial assets, solar frames, and machinery chassis.
Submersible Polyurethane Resin Cable Joint Kits
When your projects require an impenetrable structural block against severe ground movement, rocks, and persistent chemical exposure, our premium HellermannTyton Resin Cable Joint Kits deliver maximum-capacity encasement. These advanced kits utilise a high-quality, long shelf life polyurethane resin housed inside a clear casting shell that enables instant visual confirmation of the fill level. Engineered with a specialized, closed-cycle safe filling system, these resin kits allow installers to mix and inject the compound directly into the joint without exposure to liquid chemicals, curing into a rock-solid, impact-resistant block that completely seals out water, mud, and corrosive soils across buried mainline networks.
Wrap-Around Jacket Repairs and Accessible Joint Reconstruction
Executing mid-span insulation repairs on long cable runs or pre-terminated assemblies becomes completely impractical when using standard tubular heat shrink sleeves that must be slid on from an open cable end. To solve this field maintenance challenge with total efficiency, our specialised Radiform Wrap-Around Adhesive-Lined Heat Shrink Repair Sleeves feature an innovative open sheet layout that wraps directly around the target damage like a secure cuff. Held firmly in place prior to heating by a supplied set of heavy-duty stainless steel fastener rails, these rugged 1kV-rated repair wraps contract tightly over damaged cable jackets while activating a thick internal adhesive wall to restore complete structural integrity without requiring technicians to cut or disconnect any active copper conductors. This open wrap design is equally valuable when future circuit re-entry to a cable joint may be required, allowing maintenance crews to safely slice through the sleeve to inspect connections and wrap a fresh repair cuff over the assembly afterward to minimize operational system downtime.
Frequently Asked Questions
Can Radiform submersible pump kits be safely used for above ground cable joints?
Yes, while our specialized Radiform heat shrink joint kits are heavily engineered and tested to withstand continuous hydrostatic pressure underwater, their outstanding UV stabilisation and thermal resistance parameters make them perfectly suitable for above-ground extra-low voltage and low-voltage electrical circuit joins exposed to the harsh Australian climate.
What advantage does the HellermannTyton resin filling system offer to installers?
The definitive advantage of the HellermannTyton resin cable joint kits is their innovative safe filling system. This closed-mix architecture allows technicians to thoroughly blend the premium polyurethane resin and hardener within a sealed two-chamber bag and inject it into the joint shell via an integrated nozzle without ever coming into direct physical contact with raw liquid chemicals, eliminating workshop safety hazards.
Why should I choose a wrap-around heat shrink sleeve instead of cutting the cable to add a standard heat shrink tube?
Cutting a heavy multi-core power cable to slip on a standard heat shrink tube introduces unnecessary electrical termination nodes, takes significant labor time, and creates potential points of failure. A Radiform wrap-around sleeve allows you to execute a code-compliant, permanent 1kV outer jacket repair directly over a mid-span scrape while keeping the underlying copper conductors perfectly continuous and undisturbed.
How do wrap-around repair sleeves facilitate future re-entry to an electrical joint?
If a technician needs to inspect, reconfigure, or troubleshoot an inline connection node that has been sealed with a wrap sleeve, they can simply cut the polymer casing away along the stainless steel rail line to access the wires. Once maintenance parameters are successfully completed, the joint can be re-sealed instantly by wrapping a fresh Radiform repair sleeve over the area, completely avoiding full cable replacements.
