EV High-Voltage Cable introduction:电动汽车高压电缆介绍:

在电动汽车上，高压电系统主要负责启动、行驶、充放电、空调电源。主要包括电池系统、动力总成、高压电控系统、充电系统、高压设备及其线束系统。电动汽车高压线用于连接充电口与电池、电池内部、电池与发动机等部件以及电池储能设备等领域，作为电力传输的载体。由于车内应用环境恶劣，电动汽车高压电缆的性能要求非常高。电动汽车用电缆的应用特点:布线空间小，大电流高电压，高低温环境，散热性差，有盐雾和电磁场的恶劣行驶环境，油污和化学品，低烟无卤阻燃，
On electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. It mainly includes battery system, powertrain, high-voltage electronic control system, charging system, high-voltage equipment, and its wiring harness system. Electric vehicle high-voltage lines are used to connect the charging port and the battery, the interior of the battery, the battery and the engine and other components, as well as battery energy storage equipment and other fields, as the carrier of power transmission. Due to the harsh application environment in the vehicle, electric vehicle high-voltage cables have very high performance requirements. Application characteristics of cables for electric vehicles: small wiring space, high current and high voltage, high and low temperature environment, poor heat dissipation, bad driving environment with salt spray and electromagnetic field, oil pollution and chemicals, low smoke halogen-free flame retardant,

Transport and storage of cables and matters needing attention电缆的运输存储及注意事项

When cables are used with all means of transportation, such as water, land and air, please pay attention to the following matters during transportation and storage:
Prevent moisture from invading the cable, and the cable ends are tightly encapsulated.
Prevent serious bending and other mechanical damage.
Prevent exposure to high temperature and sunlight, and prohibit laying flat cable reels.
Special hoisting equipment shall be used for cable hoisting. It is strictly forbidden to hoist the wire reel horizontally or directly push the cable from high altitude.
The rotation direction of the cable tray is consistent with the rotation sign on the side of the cable tray, and it is forbidden to reverse.
In the process of cable laying, such as quality accidents caused by human beings (such as external protection)
Layer damage) should immediately repair or notify the company’s after-sales service department.
电缆使用与水、陆、空一切运输工具，在运输存 储过程中注意一下事项:
1.防止水分侵入电缆，电缆端头紧密包封。
2.防止严重弯曲及其他机械损伤。
3.防止高温及阳光下暴晒，禁止平放电缆盘。
4.电缆吊装使用专用吊装设备，严禁平吊线盘或，直接从高空推卸电缆。
5.电缆盘旋转方向与电缆盘侧面旋转标志一致，严禁倒转。
电缆敷设过程中如人为造成质量事故等(如外护
层损伤)应立即修复或通知本公司售后服务部门。

Installation and maintenance of cables电缆的安装维护

No special conditions are required for installation and maintenance, which are the same as those for ordinary cables.
安装维护无需特别条件，与普通电缆安装维护条件相同。
