1. Heat shrink cable repair sleeves are ideal for fixing scratches or damage on cables, pipes, or equipment. They can quickly restore the protective features of the cables.
2. Heat shrink wire repair sleeves provide excellent insulative protection as well as a sealing function, protecting against moisture and external environmental corrosion.
3. Heat shrink repair sleeves extend the life spans of damaged cables by giving them a strong physical structure, thus making the cables more reliable in the long haul.
One problem of long-term operation of cables is that the outer sheath is gradually damaged through mechanical wear, installation damage, UV aging, and complex environmental conditions, which leads to the invasion of water, dust, and corrosive substances inside the cable, leading to the degradation of insulation performance and possibly causing extended downtime along with an increase in maintenance and replacement costs.
Our cable repair sleeve is made with high-performance cross-linked polyolefin material that, via the heat shrinking process, wraps tightly around a damaged cable area so as to form a highly sealing protective layer. It works so well that in many cases it can completely restore the cable's insulation, waterproofing, and mechanical protection properties thereby prolonging its life.
Introduction to the Heat Shrink Repair Sleeve:
This cable accessory is used for repairing the cable sheath and its insulation, and sealing. It is composed of cross-linked polyolefin, and its advantages include superior insulation and resistance to harsh weather and climate. When installing this sleeve, one uses a hot air gun through which the heating of the sleeve leads to contraction of its size until it tightly covers and protects the cable. It can be employed for different line types and their repairs: power cables, communication cables, control cables, etc., and also in a number of fields such as industrial equipment, buildings projects, automotive wiring systems and outdoor electrical installations.

Advantages of Wire Repair Heat Shrink:
1. Sealing and protection performance.
The cable heat shrink repair sleeve, after heating and shrinking, strongly sticks to the cable surface and creates a waterproof and dustproof sealed protective layer. That protects the cable from moisture and other environmental factors. Its water absorption rate is ≤0.1% (ISO 62), which means it hardly absorbs water at all, that is the best possible condition for the prevention of water penetration. Also, the eccentricity of the sleeve is ≤30% (ASTM-D-2671), which means, it will have even shrinkage so a tighter sealing will occur.
2. Convenient installation method:
For installation, we simply need the application of heat through devices such as a hot air gun. Therefore, no complicated machinery nor the involvement of skilled workers is a requisite, making it ideal for the quick onsite repairs as well as the repair of cables confined in small areas. The longitudinal shrinkage of the goods is ≤10% (ASTM-D-2671), and the alteration in size after heating is predictable which results in ease of accurate setting and installation and also a decrease in adjustment problems.
3. Long-lasting and reliable protective performance:
We use high-performance cross-linked polyolefin materials, possessing excellent insulation properties, heat resistance, and mechanical strength. After heat aging at 130℃ for 168 hours, the change rate of tensile strength and elongation at break is ≤±20% (ASTM-D-5510), demonstrating excellent heat aging resistance. The dielectric strength is ≥15kV/mm (IEC 60243), and the volume resistivity is ≥1×10¹³Ω·cm (IEC 60093), indicating outstanding insulation performance. It can continuously protect the cable in complex environments, improve cable operational stability, and extend service life.
Applications of Cable Repair Heat Shrink:
· Power System Applications.
These tools are used to carry out regular checks as well as simple repairs of medium and low voltage cables. It also helps repair cracks and scratches in the outside layer of the cable.
· Telecommunications Industry Applications.
Applicable for repairing the outer sheath of fiber optic cables, telephone cables, and communication lines, creating an effective waterproof and water proof protective layer to stop communication lines from external environmental factors such as wind, sun light, rains and so on, thus maintaining the stability of signal transmission.

About CCMT:
Founded in 1986, the company mainly focuses on power and communication cable accessories. Through 40 years of technological accumulation and market exploration, we now operate as a professional cable accessory supplier covering research & development, manufacturing, sales, and customer service in one.
We have a cutting-edge manufacturing base with an area of 10,000 square meters where more than 200 employees are professionally engaged. A perfect production system has been set up, which spans from one of the fundamental processes - extrusion, to molding, injection molding, and expansion. We have over 40 professional machines that can satisfy both large purchasing and one-off order demands of different kinds of clients.
Depending on the nature of the product, our monthly production capacity ranges between a certain amount and remains consistent . We have 13 plastic extruders for heat shrink repair sleeve tape. We can produce cable repair heat shrink at a maximum rate of 10,000 meters per month. Outputs for other product lines vary; you may get more information after contacting us.
