Exploring the mystery of charging pile cables: high conductivity and weather resistance, smooth charging

 The product introduction of charging pile cables is generally explained from the aspects of its definition, structure, performance characteristics, application scenarios, etc.:

Definition and use:

Charging pile cables are cables specially designed for power transmission between electric vehicle charging piles and vehicles. They are mainly used to safely and efficiently transmit the power of charging piles to the battery system of electric vehicles to realize the charging function of electric vehicles.

Structural composition:

Conductor: High-purity copper or aluminum is usually used as the conductor material to ensure good conductivity and low resistance, and reduce the loss during power transmission. In order to increase the softness and bendability of the cable, the conductor is generally twisted with multiple strands of fine copper wire or aluminum wire.

Insulation layer: The insulation layer uses materials with good insulation properties, such as cross-linked polyethylene (XLPE), polyvinyl chloride (PVC), etc., which can effectively isolate the conductor from the external environment and prevent safety accidents such as leakage and short circuit. At the same time, the insulating material should also have the characteristics of high temperature resistance, wear resistance, and aging resistance to ensure the stable performance of the cable during long-term use.

Shielding layer: Some charging pile cables will be equipped with a shielding layer, which is generally made of copper wire mesh or aluminum foil. Its function is to prevent the electromagnetic interference generated by the current transmitted inside the cable from affecting external equipment. At the same time, it can also prevent the external electromagnetic field from interfering with the signal inside the cable, thereby improving the cable's anti-interference ability.

Sheath layer: The sheath layer is the outermost protective structure of the cable, and is usually made of materials with good weather resistance, oil resistance, wear resistance and mechanical strength, such as chloroprene rubber (CR), thermoplastic elastomer (TPE), etc. The sheath layer can protect the internal structure of the cable from external physical damage, chemical corrosion and climate change, and extend the service life of the cable.

Performance characteristics

High conductivity: ensure that electrical energy can be transmitted efficiently, reduce charging time, and improve charging efficiency.

Good insulation performance: can withstand high voltage without leakage, ensuring the personal safety of users and the normal operation of equipment. Generally has high insulation resistance and electrical strength.

Strong anti-interference ability: through the design of the shielding layer and other structures, it can effectively resist external electromagnetic interference, ensure the stability and reliability of the charging process, and prevent errors or interruptions in the charging signal.

High and low temperature resistance: It can maintain good physical and electrical properties in the temperature range of -40℃ to 90℃ or even wider, ensuring normal operation at different ambient temperatures.

Wear and aging resistance: It has strong mechanical strength and wear resistance, and can withstand frequent dragging, bending and other uses without being easily damaged; at the same time, in the long-term use process, it can resist the influence of factors such as oxidation and ultraviolet rays, and is not prone to aging and deterioration, extending the service life.

Flame retardant performance: It has good flame retardant properties. When encountering a fire source, it can extinguish itself to avoid the spread of fire, reduce the risk of fire, and ensure the safety of charging places.

Application scenarios

Public charging piles: It is widely used in charging piles in public parking lots, highway service areas, commercial areas and other places in cities to provide charging services for various electric vehicles. It needs to meet the charging needs of electric vehicles of different brands and models, and has high requirements for the versatility and compatibility of cables.

Private charging piles: Charging piles installed in user-owned parking spaces in residential areas, villas, etc. are mainly used to charge users' personal electric vehicles. The use environment is relatively fixed and single, and there are certain requirements for the safety and durability of cables.

Dedicated charging piles: such as charging piles set up for specific types of vehicles (such as buses and logistics vehicles) in bus stations and logistics parks. Since these vehicles have high charging power and high frequency of use, the current carrying capacity and reliability requirements of charging pile cables are more stringent.

About relevant standards: Charging pile cables need to comply with a series of national standards and industry standards, such as the new national standard GB/T, European standards, American standards and other customized cable specifications...
