Background

The power cable is used for transmitting and distributing electric energy, is commonly used for urban underground power grids, power station leading-out lines, power supply in industrial and mining enterprises and power transmission lines under river-crossing seawater, and has a gradually increasing proportion in the power line. With the development of society, people are increasingly conscious of safety and environmental protection, and the requirements on the safety and reliability of cables are higher and higher. And on occasions with higher requirements on the using environment of the line, such as the situation that a fire disaster occurs on the line, the power is continuously maintained for a certain time, and the power is supplied to the lighting equipment and the reminding equipment when the fire disaster occurs and the evacuation is carried out. However, the flame retardant performance of the existing cable is insufficient, and long-time flame retardance can not be realized when a fire disaster happens. And the general cable can emit toxic gas when burning, which is not environment-friendly enough. Therefore, we propose a halogen-free low-smoke environment-friendly copper-core power cable to solve the above problems.
