Heat-shrink tubing CellPack 266438, 30 cm length, single piece

CellPack 266438 heat-shrink tubing is designed for electrical insulation and cable protection. The tube is 30 cm long and supplied as a single piece, offering mechanical protection and strain relief for wires, splices and connectors. It is suitable for repair, maintenance and assembly tasks in electronics and electrical installations where a heat-shrink sleeve provides a durable insulating layer and improved cable routing.

Advantages

The tubing provides reliable mechanical protection and electrical insulation after heat shrinking. Its heat-shrink material conforms to irregular shapes and creates a tight, protective cover that resists abrasion and moisture ingress. The product supports quick and safe assembly processes and is suitable for field repairs as well as workshop applications. Use of an appropriately sized sleeve ensures effective strain relief and long-term stability of connections.

Suitable for

• Insulating and protecting single conductors, splices and connector joints
• Strain relief on wires and cable assemblies
• Repair and maintenance of electronic devices and electrical installations
• Improving cable routing and mechanical protection in assemblies

Key specifications

• Product type: heat-shrink tubing
• Length: 30 cm
• Pack content: 1 piece
• Function: electrical insulation, mechanical protection, strain relief
• Application: repair, maintenance, assembly in electronics and electrical installations
• Material behaviour: heat-shrinkable to conform to irregular shapes

How to use

Select a tubing diameter that fits over the conductor or connector before shrinking, allowing for shrink ratio. Position the sleeve over the area to be insulated, then apply heat evenly (for example with a heat gun) until the tubing has fully conformed and sealed around the component. Allow the sleeve to cool to achieve final mechanical stability. Ensure the work is performed following applicable safety procedures and local electrical standards.

Usage recommendations

Check cable voltage and insulation diameter before use: 12 kV cable terminations must be used for 7.2 kV cables; verify the minimum diameter over conductor insulation to ensure compatibility. Use appropriate personal protective equipment and heat tools rated for electrical work.
