Cable terminal head 10KV intermediate connector

The following are some factors that may affect the life of 3M cold shrink cable terminations: Fortune: 1368 6888 035

1. Installation quality: If the construction personnel do not operate according to the correct installation process and specifications during the installation process, such as inadequate cleaning, inaccurate installation position of the cold shrink terminal, and unstable installation of components, it may cause partial discharge, overheating, mechanical damage, etc. during the operation of the terminal, thus shortening the service life.
2. Cable quality: the quality problems of the connected cable itself, such as defects in the insulation layer, excessive conductor resistance, damage to the cable sheath, etc., will have adverse effects on the cold shrink terminal during operation, resulting in reduced life.
3. Operating environment: factors such as temperature, humidity, dust, corrosive gases or liquids in the operating environment will also affect the life of the cold shrink terminal. High temperature environment may lead to accelerated aging of insulation materials; high humidity environment is easy to make the terminal head damp, reducing insulation performance; corrosive substances will erode the material of the terminal head; excessive dust may cause partial discharge and other problems.
4. Mechanical stress: If the cable is often subjected to tensile, bending, torsion and other mechanical stresses during operation, it will be transmitted to the terminal head, which may lead to insulation damage and sealing failure of the terminal head under long-term action, affecting its service life.
5. Overvoltage: Overvoltage in the power grid, such as lightning overvoltage, operating overvoltage, etc., if it exceeds the withstand capacity of the terminal head, it may cause insulation breakdown and seriously affect its service life.
6. Load current: Long-term overcurrent load operation will increase the heating of the terminal head, accelerate the aging of the insulating material, and shorten the service life.
7. Maintenance: Lack of regular inspection, maintenance and maintenance, failure to detect and deal with problems in the operation of the terminal head in time, will also affect its service life.
