What is Charging Pile Cable? Who are the domestic and international manufacturers of Charging Pile Cable?

A. What is a charging pile cable? Charging pile cable is a kind of electric power transmission cable used for electric vehicle charging, which is an important part of connecting the battery of the electric vehicle with the charging equipment. On the charging pile, it connects the charging pile and the electric vehicle, transmits the electric energy from the grid to the electric vehicle battery, and realizes the function of charging. Charging pile cables are characterized by high voltage, high current and high frequency, and need to have high safety and reliability. Charging pile cables are mainly composed of conductors, insulation materials, sheaths and connectors. The conductor is the part responsible for delivering the current, and commonly used conductor materials include copper and aluminum, etc. Multi-stranded stranded wires are generally used to withstand large current loads. The insulation material separates the conductor from the sheath, preventing current leakage and safety issues such as electric shock. Currently commonly used insulation materials are polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), etc., with good electrical properties and abrasion resistance. Sheath is to protect the cable from external damage to the part, commonly used sheath materials such as silicone rubber, polyurethane and so on. The connector is the part that connects the cable to the charging pile and the electric vehicle, and the connector needs to have high strength and abrasion resistance, and be able to withstand multiple insertions and bending and other stresses. In the design and manufacture of charging pile cables, a number of factors need to be taken into account, such as current load, voltage level, charging speed, durability, safety and so on. The conductor cross-sectional area and insulation thickness of the cable need to be determined according to the current load and voltage level, and the length and cable diameter of the cable need to take into account the installation location of the charging pile and EV and the charging speed and other factors. At the same time, in order to ensure the safety of the charging pile cable, it is also necessary to carry out rigorous testing and verification of the design and materials of the connectors to ensure that they can withstand the stress of multiple plugging and bending, and that they will not have safety problems such as fire and electric shock. The wires of a charging pile cable usually consist of multiple strands of copper wire, as copper is a metal with good electrical conductivity. In order to ensure the conductivity and safety of the cables, copper wires need to go through a strict selection and processing process. On the surface of the wire, there is usually a layer of insulating material coated to ensure the safety and durability of the line. This insulating material is usually polyethylene, polyvinyl chloride or silicone rubber. In addition to the wires, another important part of the charging pile cable is the plugs and connectors. Plugs and connectors need to have reliable connectivity and durability to ensure that electricity can be transmitted stably between the charging pile and the electric vehicle. Plugs and connectors are usually made of metal materials, such as copper, stainless steel, or aluminum alloy. In addition to the above components, charging pile cables also need to have good protective materials to protect the cables from damage by environmental and mechanical factors. For example, the charging pile cable needs to be high temperature resistant, waterproof, fireproof, tensile strength and abrasion resistant to cope with a variety of harsh climatic and working environments. Charging pile cable is an indispensable part of the EV charging process, and its safety and reliability have a very important impact on the efficiency and safety of EV charging.
