COMMON QUESTIONS

SHENXING Cable Service FAQs

Want to learn more? Check out our electrical cable most frequently asked questions.

What environments is this anti-corrosion steel core aluminum stranded wire overhead cable suitable for?

This cable is suitable for various environments, especially in areas with strong corrosiveness such as humidity, high salt spray, acid rain, etc., such as coastal, tropical, heavy industrial areas and other harsh environments. The anti-corrosion coating can effectively prevent rust and extend the service life of the cable.

What are the special precautions for the installation of this cable?

During installation, the cable should be prevented from contacting the ground or sharp objects to prevent damage to the anti-corrosion layer. The tension should be kept uniform during the laying and stretching process to ensure that each section is firmly fixed. At the same time, it is recommended to use additional anti-corrosion materials such as waterproof tape or heat shrink tubing at the joints to ensure the anti-corrosion effect of the joints.

What is the service life of the anti-corrosion steel core aluminum stranded wire overhead cable?

Under normal installation and maintenance conditions, the service life of this cable can reach more than 20 years. Its anti-corrosion design is particularly suitable for extending the service life, especially in high humidity and high corrosion environments, and the cable life can be further extended through regular maintenance.

What is the maximum tension that this overhead cable can withstand?

The steel core structure of this cable gives it excellent tensile strength. The specific tension tolerance range depends on the cable specifications and diameter, and can usually meet the long-distance, high-tension overhead requirements. For detailed tension data, please refer to the product specification or consult our technical support team.

How to perform routine maintenance to extend the service life of the cable?

Routine maintenance includes regular inspection of the integrity of the cable's anti-corrosion coating, the sealing of the connection joints, and the tension and grounding of the cable. If the anti-corrosion coating is found to be worn or the joints are loose, they must be repaired in time to avoid environmental damage to the cable.
