Many people do not know the way to install cable connectors correctly, so next let's see the brief introduction of installing cable glands.

1. Metallic shield and ground processing

The main function of metallic shield in cable connector is to conduct cable short-circuit fault current and shield the electromagnetic interference from the electromagnetic field to adjacent communication equipment. When the equipment is running, the metallic shield should be in the zero potential with a ground condition. When the cable fails, metallic shield has the ability to conduct short-circuit current in a very short time. The connection of ground lead can be welded. The metallic shield and fitting armoured cable gland on the two ends of the cable body should be firmly welded and the terminal head should be done in a reliable way.

2. The seal of glands and the protection of machines

The seal of glands and the protection of machines are the guarantee to ensure a safe and reliable operation of the glands. A fitting armoured cable glands can be installed to prevent moisture from infiltrating into the gland. In addition, joint protection slot or cement protection box should be built around the gland.

3. Construction in rainy, snowy, foggy or gale weather

Construction in the extreme environment, the temperature, humidity and dust on the site should be under control. The air humidity should not be greater than 70% and the temperature should not be lower than zero degrees Celsius. Gale weather will bring heavy dust which may fall on the insulation layer to cause partial discharge then resulting in insulation breakdown. The solution for this situation is to put the cable accessories in a sealed tent and complete the production and installation in controlled temperature and humidity conditions.
