What is Elevator Cable? What are the domestic and international manufacturers of elevator cables?

First, what is the elevator cable? Elevator cable is an electrical component necessary for elevator operation. It is a cable that connects various electrical devices in the elevator to each other, including the motor, controller, speed limiter, door machine and so on. The safety and reliability of elevator cables are very important due to the large amount of data and signals that need to be transmitted when the elevator is in operation. In the following article, we will take an in-depth look at the structure, characteristics, application and maintenance of elevator cables. Elevator cable structure conductor: elevator cable conductor is generally used copper or aluminum wire, copper conductor transmission performance is better than aluminum wire, but the cost is relatively higher. The cross-sectional area of the conductor determines the transmission capacity of the current, so in the choice of elevator cable needs to be based on the elevator's power and load conditions to choose the appropriate conductor cross-sectional area. Insulation: The insulation layer of elevator cables is usually made of polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), cross-linked polyvinyl chloride (XLPVC) and other materials, which have good electrical insulation properties and durability. Different insulation materials have different effects on the working temperature and service life of the cable, so when choosing elevator cables, you need to consider the environment and working conditions of the cable and choose the appropriate insulation materials. Sheath: The sheath of elevator cable is usually made of polyvinyl chloride (PVC), polyurethane (PU), polyethylene (PE) and other materials, which have good mechanical strength, abrasion resistance and chemical resistance. The sheath of the elevator cable can also be added according to the need to add flame retardants and other special additives to improve the fire performance of the cable. Characteristics of elevator cablesThe characteristics of elevator cables mainly include the following aspects: good fire performance. Elevator cables usually need to have good fire resistance to ensure that the elevator can operate normally in the event of a fire and will not cause harm to personnel. High mechanical strength. Elevator cables need to withstand high-frequency motion and vibration, so they must have sufficient mechanical strength and abrasion resistance to ensure that the cables will not break in the long run. Good anti-interference performance. The signals transmitted within the elevator cable are susceptible to external interference, so it needs to have good anti-interference performance to ensure the reliability and stability of elevator operation. Wide range of adaptation. Elevator cables are suitable for different types of elevators, including freight elevators, passenger elevators, escalators and so on. High safety. Elevator cable is an important part of elevator operation, so it must have a high degree of safety to ensure the safety of people when the elevator is running. The types of elevator cables can be divided into many kinds according to different uses and structures, and the following are the common ones: rotating elevator cable: this kind of elevator cable is mainly used for high-speed elevators and skyscraper elevators, and due to the rotation of the elevator during the lifting process, this kind of cable must have high flexibility and bending performance. At the same time, it also needs to have good protection to prevent damage by external forces. This cable is usually made of high-strength copper stranded wire and high-quality PVC insulation. Elevator control cable: This cable is usually used to control the operation and stop of the elevator, including the opening and closing of the elevator door, floor display, call buttons and so on. This cable is usually made of copper single stranded or stranded wire and PVC or polyethylene insulation. Elevator power cable: This kind of cable is used for transmitting high voltage and low voltage current required by the elevator, mainly including the power supply of the elevator motor and electric braking system. This type of cable is usually made of copper single stranded or stranded wires and special insulating materials to prevent damage and danger to the cable due to high voltage currents. In addition to these common types of elevator cables, there are also other special-purpose elevator cables, such as fire-resistant elevator cables, elevator shielded cables, and specially shaped elevator cables. It should be noted that the installation and maintenance of elevator cables must be carried out by professional electrical engineers or elevator maintenance personnel.
