1. This heat shrink termination sleeve is made of a high-grade cross-linked polyolefin material with excellent insulation and very good resistance to tracking.
2. When shrunk with heat, the heat shrink anti-tracking tube will be sealed quite closely, which is a great way to provide waterproofness and moisture proofing, at the same time the tube is highly resistant to chemical corrosion and the elements, too.
3. With a minimum tensile strength of 10MPa and a minimum elongation of 300%, this heat-shrinkable anti-tracking tubing combines outstanding mechanical strength with superior flexibility.
Due to the sudden changes in conductor cross-section at the location of the wire end and cable terminal crimping, as well as the crimped edges and uneven shapes, commonly known insulation covering materials (PVC tape and regular sleeves) are not capable of producing a flawless fit that is fully sealed against the cable. Hence, either there is continuous or dispersed air gap at the contact interface. The air gaps are at risk of causing partial discharge, even though their occurrence is very low at normal voltage condition. Moreover, the insulation material's electro-aging degradation is ultimately caused by these long-term effects.
Solution:
With our heat-shrink termination sleeve you will get rid of those problems that are listed above through the heat-shrinkable material's shape memories of cross-linked polyolefin. When heating and shrinking, a constant radially inwardly directed shrinkage force is created, with which the tube wall is allowed to intimately seal the terminal crimping area, the conductor insulation layer interface section, and the irregular areas to form a completely seamless solid insulation seal.
In addition, its properties, such as an ultimate tensile strength of ≥10 MPa to counteract the mechanical stress and an elongation at breaking of ≥300% to ensure complete covering of any irregularly shaped part, were also fully taken care of.
Heat Shrink Anti-Tracking Tube:
Heat-shrinkable anti-tracking tubing serves as insulation for wire and cable junctions as well as cable terminations. Made by the material that has high insulation and the flame retarding property of polyolefin, this is the heat shrinking material. When applied to wire and cable terminations, this product is heated so that it tightly wraps around the terminals and cable connections and forms a solid insulting layer and seal. Thus, it efficiently protects against moisture from the outside, leak, short circuit, or chemicals and dust. In this manner, it also guarantees safe and stable long-term electrical insulation for connections. Heat-shrinkable anti-tracking tubing is widely used, for example, in the fields of power, industrial equipment, automotive electronics and home appliances.

Advantages of Heat Shrink Termination Tubes:
1. Non tracking insulation made of excellent quality cross-linked polyolefin material has excellent dielectric properties, providing reliable insulation protection for cable terminals. It features such characteristics that dielectric strength of 50/60 Hz and 1 minute water resistance conform to IEC 60243, volume resistivity conforms to IEC 60093, and the dielectric constant is ≤3.0, so the risk leakage can be very well reduced by this kind of materials. Such kind of insulations are widely used in the application of medium- and low-voltage and high-voltage electrical equipment, cable terminations, busbar insulation protection, etc.
2. Complies with IEC 60587 1A3.5 tracking resistance standards, and can well prevent the problem of tracking caused by moisture, dust, salt spray, and long-term electrical stress, it greatly reduces creepage and flashover risks. Compared to common insulation materials, it can keep better insulation properties for a longer period of time in high-humidity, high-pollution, and other outdoor situations, so cable terminations and electrical appliances work much more reliably.
3. When the heat shrinkage terminates, the shrink-fitted heat shrink termination tube conforms tightly to the shape of the cable head and thus forms a dependable insulation layer which completely stops the ingress of water, dust and such. With water absorption ≤ 0.5% and no corrosion after copper corrosion test running at130℃ for 168 hours, it demonstrates good chemical corrosion resistance and weatherability so that one could be confident about the long-term performance under outdoor condition, power system and harsh industrial environments.
4. The product takes the shape of a normal heat-shrink type. As a result, using a heat gun, one can install it very easily without having to do a lot of other things, leading to high construction efficiency. By tensile strength of the product being more than or equal to 10 MPa and its break elongation being more than or equal to 300%, combining super strong and flexible material, it can evenly wrap terminals of various specifications during shrinkage forming a strong and reliable insulating protective layer that won't crack due to installation or vibration.
