Simple introduction to the use of elevator rubber power cord

1. The rubber power cord should be hung freely before use, and fully withdrawn. The rubber power cord's reinforcing core should be fixed and bear the tensile force at the same time.

2. Multiple rubber power cords should be laid in rows. During operation, the rubber power cords move up and down with the elevator, and they frequently move and bend, requiring softness and good bending performance;

3. The rubber power cord is laid vertically and requires a certain tensile strength;

4, the work environment has oil pollution to be fireproof, rubber power cords are required not to ignite;

5. Requires small outer diameter and light weight.

Structure

1) Use 0.2mm round copper single wire stranding, insulation, and conductors wrapped around the insulation layer, twisted in the same direction when the cable is formed to increase the flexibility and bending performance of the rubber power cord;

2) A rubber power cord reinforced core is added to the rubber power cord to withstand mechanical tension. The reinforced core is made of nylon rope, steel wire rope, and other materials to increase the tensile strength of the rubber power cord;

3) YTF rubber power cord uses a neoprene-based sheath to improve the weather resistance and non-flammability of the rubber power cord.

How to identify the quality of the power cord

First, look at the quality certificate of home appliances If the quality of the home appliance is qualified, then the quality of the power cord of the home appliance should also be tested, and there will be no major problems. Second, check the cross-section of the wire In the cross-section of the w...
