China Reliable Cable Accessories Manufacturer
The cable accessories produced by TAILI are important components used for installation, connection, sealing, protection and management of electrical or data cables. By connecting the cables, connecting them to equipment or protecting them from moisture and stress, they ensure the safe, reliable and efficient transmission of power or signals. Examples include connectors, seals, terminations and ropes, etc. They restore the performance of the cables at the joints and terminations, extend the service life of the cables, and maintain the integrity of the system in power grids, substations and industrial facilities, together with the cables forming a complete and functional network.
Why are cable accessories necessary?
1. Electrical connection function: Ensure reliable connection of the cable conductors with those of other devices, maintaining a low-resistance and low-loss path.
2. Insulation recovery function: At the cut ends of the cable, the accessory must provide insulation strength equal to or even stronger than that of the cable itself to withstand the system voltage.
3. Electric field control function (the core technology): This is the essence of the accessory design. After the cable is cut, the uniform electric field distribution inside it will be severely distorted, resulting in extremely high electric stress concentration at the conductor ends (a sharp increase in electric field intensity), which is highly likely to cause insulation breakdown. The accessory re-establishes the uniform electric field distribution through structures such as stress cones and stress tubes.
4. Sealing protection function:
- Longitudinal waterproof and moisture-proof: Prevent water from entering along the cable interior or interface, leading to a decline in insulation performance.
- Radial sealing: Prevent corrosion of the connection points by the external environment (moisture, chemicals).
5. Mechanical protection function: Provide certain mechanical support, shock resistance, and tension resistance to protect the vulnerable connection points.
How to choose the suitable cable accessories?
1. Determine the type and specification of the cable
•The accessories should be consistent with the purpose of the cable
•The voltage and current of the accessories should be the same as those of the cable
•The conductor material and cross-sectional area of the accessories should be the same as those of the cable
•The structure of the accessories should be consistent with that of the cable, single-core/multi-core, whether armored or not, whether shielding is required.
2. Analyze the usage environment
•Indoor/outdoor, outdoor requires consideration of sun protection, waterproofing, and dustproofing
•Buried/overhead, buried should be resistant to moisture and corrosion, overhead should be resistant to weathering and UV radiation.
3. Evaluate the performance of the accessories
•Electrical performance: Ensure uniform electric field distribution, reliable insulation performance, low dielectric loss
•Thermal performance: The contact resistance at the connection point should be small and stable, with good heat dissipation, and able to adapt to thermal expansion and contraction.
•Mechanical performance: High strength, resistant to wear, able to withstand the stress during installation and operation.
•Weather resistance/corrosion resistance: Anti-aging, strong environmental tolerance
4. Select the appropriate accessory type
•Cold shrink accessories: Silicone rubber/epoxy rubber, with elasticity, contract after installation, good sealing performance, commonly used for medium and high voltage.
•Heat shrink accessories: Contract after heating, suitable for various voltages and environments.
•Pre-assembled accessories: Easy to install, stable quality, suitable for high voltage.
•Separable connector: Connect the cable to equipment (such as switch cabinets, transformers, etc.), requires matching conductor material and conductor cross-sectional area.
5. Consider installation and maintenance
•Construction convenience
•Maintainability

It is mainly used to safely and reliably connect two sections of cables together.
Heat Shrink Tube
Heat shrink tube is a kind of intelligent polymer material sleeve that contracts upon heating. You can buy this product from Taili factory in China. It utilizes the elastic memory effect to tightly wrap around objects after being heated, thereby achieving insulation, sealing, protection and identification functions.
Cold Shrink Cable Termination Kit
This Cold Shrink Cable Termination Kit is an advanced, efficient and safe cable connection technology, offered by China manufacturer Taili. Through its unique physical principle, it offers excellent insulation, sealing and reliability, while significantly simplifying the installation process and enhancing operational safety.
Cold Shrink Cable Joint Kit
Cold Shrink Cable Joint Kit, one of Taili Factory's high-quality products, is a crucial technology in modern cable engineering. Through the cold shrink technique, it provides a fully enclosed, fully insulated, and fully sealed solution for the middle connection part of the cable, ensuring the continuity of the entire cable line and the reliability of its long-term operation.
Cold Shrink Tube
A cold shrink tube is a tubular sleeve made of pre-expanded elastic material. Taili has its own factory to produce this product. During installation, no heating is required. Just remove the internal support, and it will automatically contract and tightly wrap around the object's surface, achieving the functions of insulation, sealing, protection and stress dispersion.
