The uses of cable accessories
Cable accessories have the following functions:
1. Connection: Achieve reliable connection between cables, equipment or other electrical components.
2. Insulation: Provide necessary insulation protection to prevent leakage and short circuits.
3. Sealing: Prevent the influence of external factors such as moisture and dust on the cable to ensure long-term stable operation.
4. Protection: Protect cables from mechanical damage and environmental influences, and extend their service life.
5. Compensation: Provide necessary flexibility and compensation when the cable expands or contracts due to temperature changes or when the foundation settles.
Advantages of our cable accessories
High-performance material:
Use high-performance liquid silicone rubber material, enhance the stress cone structure, the electric field distribution is uniform and reasonable, the voltage level can reach 27.5kV insulation level, there is a certain safety margin, cost-effective;
Prevent the retraction of cable insulation:
Aiming at the problems of smooth conductors and large insulation retraction of profile conductor cables, the length of the high-voltage inner shielding tube at the intermediate joint is optimized and extended by approximately 30% compared to traditional cable accessories. This can effectively prevent accidents where the high-voltage conductor falls out of the shielding range of the inner shielding tube due to insulation retraction of the cable.
Reliable electric field shielding:
The outer shield of the intermediate joint is 2.5mm semi-conductive shield layer with high temperature and high pressure integrated injection molding, solid bonding and reliable electric field shielding. Avoid the breakdown failure that occurs when the traditional spray semi-conductive layer falls off or expands, resulting in unreliable shielding.
FAQ
01.What does cable accessory include?
02.What's the difference between heat shrink tubing and cold shrink tubing?
Heat shrink tubing is usually made of thermoplastic polyolefin. After heating, it shrinks to its original size and is wrapped around cables or joints. It is commonly used for cable joints, insulation and protection. Installation requires the use of a hot air gun or other heating tools.
Cold shrink tubing is usually made of elastic polymers. Used at room temperature, the sleeve itself is pre-stretched and loosened during installation to return to its original shape. It is mostly used for the sealing protection of cable terminals and joints. No heating is required. Just put it on directly. The installation is more convenient.
03.What are the differences in shrinkage ratio and weather resistance among heat shrink tubing made of different materials？
04.What is the material of your heat shrink cable?
05.The advantages of cross-linked polyethylene (XLPE) over other insulating materials:
