Characteristics and application requirements of wire harness

For the wiring harness of elevator, safety insurance system is a test. In recent years, we learned from the news that many elevator injuries have occurred, mainly because of the elevator aging or system problems, leading to accidents. It is self-evident that the elevator harness plays an important role in the safe and stable operation of the elevator. What are the requirements of elevator wire harness in the process of processing? How to ensure the product quality? Let's listen to the analysis of wire harness processing factory


Bundle requirements:
1. The cable shall be freely suspended and fully retracted before use, and the cable reinforcement core shall be fixed and bear the tensile force at the same time;

2. Multiple cables shall be arranged in rows. In the process of operation, the cable moves up and down, the elevator moves, moves and bends frequently, which needs good flexibility and bending performance;
3. When the cable is placed vertically, it needs a certain tensile strength;
4. The working environment is oily and fireproof, and the cable is not required to be flame retardant;
5. Small outer diameter and light weight are required.

Structural features of elevator harness:

1. 0.2mm round copper single strand is used, and the insulation layer is wrapped between the insulation and the conductor. When the cable is twisted in the same direction, the flexibility of the cable increases. Bending property;

2. The reinforced core is made of nylon rope and steel wire rope to increase the tensile strength of the cable;

3. YTF cable uses chloroprene rubber sheath to improve its weatherability and non flammability
