Due to the short circuit of the high-temperature fan outside the cable, short circuits occurred in all parts of the cable. Generally, this is caused by poor cable quality due to wind exposure, resulting in severe damage to the cable at the defective points; however, obvious traces will still remain. Once a short circuit occurs in the cable tray, the entire cable may be burned out, and the slack of the cable at the defective point is slight.

When replacing the cable tray, conduct on-site observation at the construction site before starting work to confirm the issues with the tray. In fact, compared with replacing the tray, how to maintain and preserve it is an important aspect in daily use.

Daily Maintenance:

Regularly wipe off surface dust with a clean, soft cloth.

Regular Maintenance:

Uniformly wipe the exterior with a special wax polish, then buff with a clean, soft cloth after a while to ensure flexible operation, rust resistance, and oxidation resistance. As a general rule, maintenance can be performed quarterly.

Wipe hardware accessories and metal handles with a small amount of oil and dry them to prevent moisture damage. This should be done after wiping off dust from the frame with a soft cloth.

For Galvanized cable trays:

Use a dry, clean soft cloth and special maintenance wax.

During daily maintenance, avoid wiping the painted surface, mirrors, and glass with damp cloths or hard objects.

Avoid contact with acidic, alkaline chemicals, and oily substances.

Keep the room well-ventilated and dry.

The cable tray should be protected from high temperatures and humidity.

Avoid contact with corrosive liquids such as alcohol and nail polish remover.
