1. The rubber power cord should be hung freely and fully twisted before use. The rubber power cord's reinforcing core should be fixed and bear the tension at the same time;
2. Multiple rubber power cords should be laid in rows. During operation, the rubber power cords move up and down along with the elevator. They move and bend frequently, requiring softness and good bending performance;
3. The rubber power cord is laid vertically and requires a certain tensile strength;
4. If there is oil pollution in the working environment, fire prevention is required, and the rubber power cord is required to not extend combustion;
5. Small outer diameter and light weight are required.
structure:
1. Use 0.2mm round copper single wire bundle to twist, wrap the isolation layer between the insulation and the conductor, and twist in the same direction when forming the cable to increase the flexibility and bending performance of the rubber power cord;
2. Add rubber power cord reinforcing core to the rubber power cord to withstand mechanical tension. The reinforcing core is made of nylon rope, steel wire rope and other materials to increase the tensile strength of the rubber power cord;
3. YTF type rubber power cord adopts neoprene as the main sheath to improve the weather resistance and non-flammability of the rubber power cord.
