Sales description of automotive high-voltage cables

详情

It mainly includes:  battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment, and its wiring harness system. The electric vehicle high-voltage wire is used to connect the charging port to the battery, inside the battery, between the battery and the engine and other components, as well as battery energy storage equipment and other areas, as a carrier for power transmission. Due to the harsh environment of in-vehicle applications, electric vehicle high-voltage cables have very high performance requirements. It must undergo strict power cable testing for use and achieve high standards for production requirements.

The high-voltage system of electric vehicles is characterized by high voltage, high current circuits, and safety. Its importance cannot be overstated. Human contact can cause injury. Meanwhile, the design and layout of the car's high-voltage wiring device is very important. In addition, green travel is a concept currently promoted. Nowadays, short-distance public transportation is gradually replaced by new energy vehicles, and the requirements for the high-voltage cables of new energy vehicles are getting higher and higher.

Application:  In automobiles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air-conditioning power.

High voltage cable consists of sheath, braid, tape, conductor and insulation layer (from outside to inside). This includes also shielded and unshielded cables. Of course, considering the harsh environment of high-voltage cables, the requirements for use in various regions vary greatly, and the relevant professional and technical personnel should be consulted before use to understand the size of high-voltage cable specifications and the length of the cable required.

Voltage issues:  The main difference with ordinary automotive cables is that the frame must be set to a rated voltage of **0V, while in commercial or bus applications the rated voltage can be up to ***0V. ; Current cables for vehicles driven by internal combustion engines are designed for a rated voltage of *0V. For current issues, depending on the different specifications of different cables carry different currents, from *0A**0A of current, etc.

Temperature issues:  Except for the engine compartment or hot compartment of the vehicle, the rest of the temperature is usually used to withstand **5°C, while high-voltage cables for new energy sources are usually higher. than the normal value, such as **5℃ or **0℃. Different places have different requirements for cables.

Operating life:The accepted standard for cables is ***0h, a value commonly used in tests for long-term aging. In the field of high-voltage applications in the field of high-voltage applications will have special requirements, may exceed ***0 h, in the specified temperature cumulative operating time even up to ****0 h.

Safety markings:High-voltage electricity will bring certain risks to the user, high-voltage cables should be visually distinguished from ordinary cables, and also marked with safety warning signs.

The above can be distinguished from the surface of the logo, so that the user can have a security guarantee.
