What Factors Will Accelerate The Aging Of Cable Waterproof Joints?

Nylon Cable Gland Damage and failure will directly affect the normal use of the cable. The service life of the connectors produced by regular manufacturers is about fifteen years. However, due to the complexity of the actual use environment and conditions, the actual service life of many connectors cannot reach this period. So what factors will accelerate the aging of the connector?

1. Oxidation.

The cable waterproof connector itself has a certain expansion coefficient, but due to the different materials used in the connector, the gaps produced are also different. If the manufacturer does not ensure the sealing of the connector during production, it is easy to cause gaps in the connector, resulting in the connector being not waterproof inside, and moisture or water droplets will enter the connector, causing the shielding oxide layer to be gradually oxidized.

2. Insulation dampness.

This is one of the common factors that cause the aging of cable waterproof connectors. It is more likely to occur at direct buried or pipe joints. When the connector quality is unqualified, or moisture enters the connector during installation, the connector is damaged by the electric field, causing the insulation layer of the cable to be damaged.

3. Accumulated charge.

If the material of the cable waterproof connector used is inconsistent with the material used for the inner and outer conductors of the cable, it is easy to generate accumulated charge. When the material of the cable changes from copper to aluminum or alloy, the original low-resistance medium becomes a high-resistance medium, and accumulated charge will be generated at this time. The accumulated charge will cause electric field distortion, which will cause the connector to age.

In summary, the factors that cause the accelerated aging of the cable waterproof connector are oxidation, insulation moisture and accumulated charge. Of course, there are many other relatively small factors in actual use that will affect the service life of the connector, which are not briefly described here.
