The mobile cable reel refers to a removable cable reel wound with wire and cable. The cable reel is equipped with a national standard socket or an industrial socket. It has a leakage protector and a power indicator. It is used as an outdoor power supply. The cable reel should have a cable reel bracket and handle, and the larger cable reel has casters.

The cable reel is divided into two types: non-electric and electric according to the driving mode; according to the cable arrangement, it is divided into axial single row and axial multi-row; according to the position of the collector slip ring, it is divided into slip ring built-in type and slip ring There are two types of exterior type; according to the winding material, it is divided into Kaihui cable reel and hose reel. Among them, non-electric type includes: elastic (TA) type, weight (ZC) type, magnetic coupling type (JQC); electric type includes: magnetic coupling type (JQD), torque motor type (KDO), hysteresis type (CZ) And frequency conversion control (BP) and so on. The working principle of the flexible cable reel is similar to the steel tape measure, and the coil spring cable is powered by the coil spring. When the cable is pulled out, the volute spring is tensioned to store energy. When the external force is withdrawn, the spring releases energy and the reel will automatically rewind the cable.
