Motorized cable reel which is used for large size and long distance cable, which can be in synchronous operation with the mobile electric apparatus to coil up or spool off the cable. In view of its drive modes, there are torque motor type, long term locked torque motor type, hydraulic coupling type, magnetic hysteresis type and variable frequency motor type. The control loop of the reel provides the interface to the main control loop to keep in synchronous operation with the electric apparatus to coil up or spool off the cable. Its torque adjuster is employed to adjust the cable tension and make the cable durable.
There are so many motorized cable reels available which can coil up or spool off the electric cable under 500V and high voltage cable for 6kV and 10kV.
