Versatile, Reliable Insulation Restoration

These cable repair products are purpose-built for quick field repairs or emergency cable restoration. Their robust composition ensures high dielectric strength, excellent tensile strength, and strong resistance to chemicals, oils, fungus, and UV exposure. The flexible material conforms to irregular surfaces, making it ideal for restoring insulation integrity, preventing moisture ingress, and securing cable joints in both indoor and outdoor environments.

Easy, Efficient Installation for All Applications

Installation is simple: wrap or slide the heat shrink product over the damaged area, then apply heat with a hot air gun until the product conforms and seals. Optional adhesive lining ensures waterproof, airtight protection. Products are available in individually packed sleeves or bulk rolls, in various colors and sizes to suit LV/MV single and multicore cable repairs. Shelf life is up to 36 months under recommended storage.

FAQs of Cable Repair Products:

Q: How do I use heat shrink cable repair products for damaged cables?

A: To use these products, first clean and prepare the damaged cable area. Place the heat shrink sleeve, wrap, or spiral over the section. Then, using a hot air gun, apply heat evenly until the material shrinks to fit snugly. The integral hot melt adhesive lining activates to create a waterproof and environmentally sealed repair.

Q: What types and sizes are available for different cable repairs?

A: Cable repair products are available in various shrink ratios (3:1 or 4:1), diameters (10mm to 100mm), lengths (1m, 2m, 5m, or custom), and colors (black, red, blue, yellow, green). Wrap-around, spiral, and patch variants cater to single core, multicore LV/MV cables, and irregular cable surfaces.

Q: When should I use heat shrink repair products instead of replacing the entire cable?

A: These products are best used for quick field repairs, emergency restorations, or when replacing the entire cable would be time-consuming or costly. They are designed to restore insulation integrity, prevent further damage, and provide waterproof and UV-stable protection in both outdoor and indoor applications.

Q: Where can these products be applied, and are they suitable for outdoor use?

A: Heat shrink repair sleeves and wraps are suitable for power and telecommunication cables, including those installed outdoors. Their robust construction provides resistance to chemicals, oils, fungus, and UV exposure, making them ideal for harsh environments and outdoor installations.

Q: What tools are recommended for effective installation?

A: A hot air gun is the most recommended tool for shrinking and activating the adhesive lining. Scissors or a cutter can be used to trim the product to the required length prior to installation. No special chemicals or equipment are required beyond standard safety gear.

Q: What are the main benefits of using these cable repair products?

A: Benefits include high insulating capability, excellent flexibility for irregular cables, quick installation, strong environmental and water resistance, flame-retardant properties, and long-term durability. They also offer RoHS compliance and can be stored for up to 36 months if kept at recommended conditions.

Q: What should be considered for storage and shelf life of these products?

A: Store the products at temperatures between -10C and +50C in a dry, cool environment. When stored as recommended, they maintain a shelf life of up to 36 months without degradation of performance or reliability.
