Specifications And Requirements For The Use Of Metal Waterproof Cable Connectors

Nylon Cable Gland What specifications and requirements should be followed during use?

1. The cable conductor should have low resistance when connected and have a certain mechanical strength. There should be no sharp corners at the connection. Generally, the cable conductor is connected by crimping. During crimping, the gap between the inner diameter of the crimping tube and the outer diameter of the wire core should be controlled at 0.8-1.4mm. After crimping, the resistance value of the joint should not exceed 1.2 times the cross-sectional conductor. The connecting tube and the wire core conductor should be smooth without burrs or sharp corners.

2. The inner semiconductor shielding needs to be handled well, because the body of the cable has an inner shielding layer. When connecting the joint, a part of the inner semiconductor shielding of the cable should be left out to ensure that the inner semiconductor can achieve continuity.

3. The outer semiconductor shielding needs to be done well. The insulation part of the cable and the metal heat-proof cable joint mainly plays the role of uniform electric field. The port part of the outer semiconductor should be uniform and neat, and can have a good transition with the insulation layer. The outer semiconductor shielding of the joint and the cable body can be effectively connected.

4. The shape and size of the reaction force cone should be accurate during construction. Special cutting tools are required to ensure that the shape and size of the reaction force cone meet the actual construction requirements. After forming, thick glass can be used for scraping and sandpaper can be used for smoothing.

In addition, the sealing and mechanical properties of the metal waterproof cable joint must be guaranteed, because this is the basic condition for the safe and stable operation of the cable. In order to avoid dust and moisture entering the joint, in addition to purchasing joint products with good quality and high protection performance, a protective box can be installed at the joint connection.
