Heatshrink

Licensed electricians and contractors rely on quality heatshrink solutions for professional cable management, insulation, and protection across residential, commercial, and industrial projects. iSupply Electrical stocks an extensive range of heatshrink tubing, cable ties, and specialized insulation products designed to meet Australian electrical standards while keeping your projects on schedule and within budget.​

Professional Cable Management Solutions

Heatshrink tubing provides essential electrical insulation for wire splices, terminals, and connections, preventing short circuits and protecting against moisture, dust, and abrasion. From thin-wall heatshrink in various diameters to heavy-duty stainless steel cable ties rated for harsh industrial environments, this category delivers the cable management components electricians need for secure, compliant installations.​

Our heatshrink product range includes CABAC thin-wall tubing kits (3-25mm), specialized yellow/green earth sleeving, and complete heat shrink kits for field applications. For demanding industrial and commercial projects, PowerJoint busbar insulation tubing and constant force springs provide medium-voltage insulation solutions that meet rigorous safety requirements.​

Cable Ties for Every Application

Professional-grade cable ties are essential for organizing wiring in distribution boards, switchboards, and cable trays. Our selection includes standard nylon ties in multiple lengths (280mm, 356mm) with double-lock mechanisms, plus premium SS316 stainless steel ties ideal for outdoor, marine, and corrosive environments. UV-resistant loom tubing and coated cable ties extend service life in solar installations and exposed applications.​

Frequently Asked Questions

What size heatshrink tubing do I need for electrical cables?

Heatshrink tubing shrinks approximately 2:1 or 3:1 when heated, so select tubing with an internal diameter at least 20-30% larger than your cable diameter before shrinking. For standard electrical connections, 9.5mm to 25mm thin-wall tubing covers most residential and light commercial applications, while 50mm+ diameters suit larger industrial cable bundles.​

Are stainless steel cable ties necessary for outdoor electrical installations?

SS316 stainless steel cable ties resist corrosion, UV degradation, and temperature extremes far better than standard nylon ties, making them essential for outdoor switchboards, solar installations, and marine environments. Standard nylon ties with UV-resistant coatings provide adequate protection for covered outdoor applications at lower cost.​

What’s the difference between thin-wall and medium-voltage heatshrink?

Thin-wall heatshrink (like CABAC XLP series) provides basic electrical insulation and mechanical protection for low-voltage wiring and cable splices. Medium-voltage busbar insulation tubing offers significantly thicker walls and higher dielectric strength for switchgear, distribution boards, and industrial busbar systems where higher voltages require enhanced insulation properties.​

Can I use heatshrink tubing for cable repairs on-site?

Heatshrink tubing provides excellent emergency repair solutions for damaged cable insulation, allowing electricians to restore protection without replacing entire cable runs. Adhesive-lined heatshrink creates waterproof seals ideal for outdoor repairs, though permanent solutions should be implemented during scheduled maintenance.​

How do I apply heatshrink tubing correctly?

Cut heatshrink to length allowing 10-15mm overlap on each side of the connection, slide over the cable before making your splice, then position it centered over the joint. Apply even heat using a heat gun at the shrink temperature (typically 120°C) starting from the center and working outward to eliminate trapped air. Avoid overheating which can damage the tubing or underlying insulation.​​
