Difference between metal cable gland and nylon cable gland

      The metal cable gland can operate well under various environments such as high temperature, high humidity, high vibration and high impact.

1. Connection method: this connection method refers to the connection method of waterproof joint male and female connector and hardware contact part of wire and cable. In addition to shielding joint, the performance of metal and nylon PA66 shell is similar. Nylon material is cheaper than metal material, and the structure is more reasonable.

2. Electrical performance: rated voltage, rated current, contact resistance, insulation resistance, etc. shall be in accordance with the specified standard value. Under this condition, the performance of metal and nylon cable gland is similar.

3. Environmental parameters: Environmental parameters mainly include ambient temperature, humidity, temperature change, atmospheric pressure and corrosive environment. The environment during storage, transportation and use has a significant effect on the performance of cable glands. Therefore, you can choose whether or not to use a metal shell based on actual environmental conditions.
