Causes And Hazards Of Heating Of Cable Waterproof Joints

When using Nylon Cable Gland, it is inevitable that the connector will heat up. Once this happens, you need to be alert and cool it down in time, otherwise it will cause danger. Today we will talk about the causes and hazards of connector heating.

1. Hazards of heating of joints

1. Overheating, burns, short circuit, power outage

2. Waste of electric energy

3. Cause explosion, fire

4. Endanger personal safety

2. Causes of heating of joints

Human factors

1. The contact surface is not properly handled during installation and connection

2. Rough cable stripping causes damage to the conductor

3. The core of the conductor is not properly handled during the connection process

4. Insufficient pressure during crimping

5. There are gaps during connection

6. The insulation and sealing of the cable joint are not properly handled

Objective factors

1. The actual contact area is too small

2. The contact surface is oxidized and corroded under the influence of the natural environment

3. Fatigue looseness and micro-vibration of the contact surface

4. Poor protective materials

3. Prevention of heating of joints

Use qualified power compound grease and apply it in accordance with regulations.

According to actual data collection, it is found that power grease can play an important role on metal joints, such as anti-corrosion, anti-fatigue and anti-wear. However, if you want to get this protection for a long time, the power grease used should be qualified and of high quality.

If unqualified power composite grease is used, it will not only fail to play a protective role, but will increase the corrosion of the joint and even the contact resistance, which will bring adverse effects.

It can be said that it is very important to do a good job in preventing the heating of cable waterproof joints.
