I. Structure and Materials:
Conductor: Usually made of multiple strands of fine copper wire twisted together to improve electrical conductivity and flexibility, meeting the requirement of frequent bending of the cable during elevator operation.
Insulation Layer: Common insulating materials include polyvinyl chloride (PVC) and cross-linked polyethylene (XLPE), etc. PVC is widely used due to its good electrical and processing properties, while XLPE has gradually become the mainstream choice because of its excellent electrical and heat-resistant properties.
Filler: Generally non-hygroscopic materials such as nylon and polyester fibers are used to fill the internal gaps of the cable and enhance the overall strength of the cable.
PB Layer: Usually a metal mesh structure or metal foil, which can prevent electromagnetic interference and lightning surge, ensure the stability of signal transmission, and is often used in occasions with high requirements for signal transmission.
Outer Sheath: Serves to protect the cable. Common materials include PVC, polyurethane (PU) and nylon, etc. PU is widely used due to its excellent wear resistance, aging resistance and oil resistance.
II. Main Characteristics:
Bending Resistance: When the elevator runs, the traveling control cable moves up and down frequently along with the car, so it needs to have good bending resistance and withstand multiple bends without damage.
High Tensile Strength: The cable needs to bear its own weight and the tension generated during elevator operation. Steel wires or other reinforcing cores are usually added to improve the tensile strength.
Good Insulation Performance: It can maintain good insulation performance under various environmental conditions during elevator operation, ensuring the safety and reliability of power transmission and signal transmission, and preventing faults such as electric leakage and short circuit.
Wide Temperature Adaptation Range: Generally, it can work normally in an ambient temperature range of -40°C to 70°C. Some types of cables can still maintain flexibility at a low temperature of -15°C.
III. Application Scenarios:
Home Elevators: Usually use PVC-insulated elevator traveling cables, focusing on durability and economy, which can meet the basic needs of home elevators.
Commercial Elevators: Due to high usage frequency and heavy load, double-steel-wire load-bearing core cables are commonly used. They can provide overall electrical control under long-distance suspension, while bearing mechanical stress, and have good PB anti-interference effect.
Hospital Elevators: With extremely high requirements for safety and stability, high-performance XLPE-insulated elevator traveling cables are often used, which can effectively reduce the failure rate and ensure the long-term stable operation of the elevator.
