Description

Cable retractor for new power system

technical field

The invention belongs to the technical field of power auxiliary equipment, and in particular relates to a cable retracting and unwinding device for a novel power system.

Background technique

A power system with the basic characteristics of clean and low-carbon, safe and controllable, flexible and efficient, intelligent and friendly, and open and interactive. As an important element in the new power system, the cable is mainly used for the transmission of strong electric energy in the generation, distribution, transmission, transformation and power supply lines. In the process of construction and maintenance of new power systems, it usually involves the arrangement of cables. The cables are wound through the cable reel, and then transported to a suitable location for unwinding.
