Why do cable trays age? How should we handle it?

What are the reasons for the aging of cable trays during use? What should we do to prevent the aging of cable trays? Below, we will analyze in detail the causes and solutions of cable tray aging.

What are the reasons for the aging of cable tray suppliers?

1. Insulation humidity conditions; This situation is also very common, usually occurring at the cable joints of buried pipelines or drainage pipelines.

2. Corrosion of chemical raw materials; Cables are directly buried in areas with acid-base effects, which usually result in corrosion of the cable's armor or outer protective layer. The maintenance layer is subjected to chemical or electrolytic corrosion for a long time, leading to maintenance layer failure, insulation reduction, and cable failure.

3. Long term overload operation; Excessive temperature can accelerate insulation aging and insulation breakdown.

4. Cable joint failure; Cable joints are weak links in cable lines, and direct personnel errors (poor construction) often lead to cable joint failures. In the manufacturing process of cable joints, if any joint is not tightly crimped. Insufficient heating of the original network can cause insulation degradation of cable heads, leading to malfunctions.

5. Environmental and temperature factors: The external environment and heat sources around cable trays and cables can also cause high cable temperatures, and in severe cases, insulation breakdown can lead to explosions and fires.

How to deal with the aging of cable tray suppliers? We can use hot-dip galvanizing process. Zinc has excellent corrosion resistance, and the immersion life of zinc depends on the corrosion resistance and corrosion rate of its galvanized layer. Galvanizing technology is also possible. For cable trays without special requirements, galvanizing process is simpler and cheaper than hot-dip galvanizing. In powder coating technology, PVC materials are usually powder coated, polyester powder or anti-corrosion powder, with a coating thickness of about 60m. For large components, due to the limitations of galvanizing equipment, only anti rust paint can be used for treatment. When we use cable trays, if we cannot make timely judgments when faults occur, it may cause losses. Therefore, we need to regularly maintain them to reduce the occurrence of faults.

The above is the reason and treatment process for cable tray aging that I have introduced to you. The installation of cable trays should be carried out according to actual needs.
