The performance requirements that the cable needs to meet must be clearly determined

1. Anti-ultraviolet, anti-sun and aging means the same thing. The biggest reason for the aging of outdoor cables is ultraviolet radiation;

2. Other factors that affect the service life of the cable:

It is resistant to rain shower, weak acid and alkali, high temperature, etc. It will inevitably be affected by rain, fog, moisture and other long-term exposure to the sun when used outdoors. If it does not have hydrolysis resistance, it will cause problems such as leakage and short circuit. To the safety of life and property; with the intensification of industrialization, the harsh environment of acid rain has appeared in many areas, and this requirement should be taken into account to avoid a certain degree of corrosion to the cable, which will cause more hidden dangers; in addition, the Southeast Asian region It is located in the tropics, and its temperature is high all the year round. It is required that the cable should not be softened when used in high temperature, resulting in problems with withstand voltage and insulation performance.
