Heat Shrink Tapes
Radiform heavy duty heat shrink tape provides high-voltage insulation and robust environmental sealing for complex cable joints, terminations, and structural busbars. Designed by Radiform Australia, this premium protective wrap accommodates irregular configurations and uneven substrates that standard heat shrink tubing cannot slip over. The dual-purpose composite matrix acts as both a primary dielectric shield and a permanent moisture barrier, ensuring long-term operational safety across utility, industrial, and electrical engineering infrastructure.

Core Engineering & Installation Advantages
High-Voltage Dielectric Integrity
This cross-linked polyolefin composite tape delivers exceptional electrical insulation performance, making it completely safe for operational AC environments scaling up to 25kV. It is heavily utilised for retrofitting switchgear assemblies, reinforcing busbar clearances, and fortifying heavy industrial distribution panels where pre-formed boots or rigid sleeves are impractical to install.
Advanced Hot-Melt Adhesive Fusion
The interior surface features a highly calibrated hot-melt glue layer that liquefies under targeted heat activation. As the tape shrinks tightly around the component, the adhesive flow fills air gaps and amalgamates the overlapping wrap layers into a single, continuous, and completely waterproof protective sleeve.
Linerless High-Speed Application
Engineered without a separate backing tape or clear release liner, this design removes field installation steps and eliminates waste cleanup on busy job sites. The non-tacky formulation ensures the tape is easy to unspool and slide into tight spaces without prematurely sticking to itself, tools, or nearby hardware prior to the final heat-shrinking process.
Permanent Cable Sheath Repair
The heavy 1mm material thickness serves as a rugged sacrificial layer with high mechanical resistance to surface cuts, impacts, and long-term abrasion. This makes it an ideal wrap-around maintenance solution for repairing damaged outer jackets on underground cables, trailing mining cables, and exposed conduit infrastructure without requiring line cuts.
Frequently Asked Questions
Can this tape be used to insulate bare copper busbars in medium voltage cabinets?
Yes. Radiform heavy-duty tape is purpose-built for busbar insulation systems carrying operational voltages up to 25kV. Wrapping bare copper rails with this adhesive-lined material decreases the required physical phase-to-phase and phase-to-earth clearances, allowing electrical engineers to construct more compact switchgear enclosures
How does Radiform heat shrink tape seal irregular configurations or T-joints?
Standard cylindrical heat shrink tubing requires an open cable end and struggles to conform snugly to multi-directional branches or dramatic diameter changes. Because this material is wrapped as a flexible flat tape, installers can layer it in alternating directions over T-junctions, structural bolts, or asymmetrical couplings before applying heat to activate the full cross-linking shrinkage and internal glue flow.
Will the tape degrade or unravel if exposed to outdoor environments?
No. The heavy-duty polyolefin backing material is engineered to resist chemical exposure, moisture ingress, and thermal stress. For permanent outdoor or high-sunlight utility installations, choosing the black UV-stabilised variant ensures the long-term integrity of the polymer structure against solar degradation and weathering.
