The cable drum powered transfer trolley cable carrier is sufficiently spaced from the reel to eliminate the need for a cable assembly

There are many factors affecting the current carrying capacity of cable drum powered transfer trolley, such as working voltage, current type, frequency, cable structure, cable arrangement on the reel, etc.; high operating temperature, ambient temperature and heat dissipation conditions allowed by the main core. Therefore, on the basis of a large number of tests, the current carrying capacity of the cable is comprehensively analyzed, and the reasonable service life of the cable insulation under certain working conditions is considered.

When the actual conditions of use and test conditions are inconsistent, they should be corrected to take into account the differences between the two. Therefore, there are two issues to consider when choosing cable specifications:

First, how to determine the actual working current through the cable drum powered transfer trolley.

Second, determine the main correction factors that affect the current carrying capacity.

On electric flat cars, each manufacturer uses a narrower reel that is about six times the width of the cable. In this case, if the cable carrier is sufficiently spaced from the winding reel shaft, it is not necessary to use a cable arrangement and the surface of the reel is guided by a spiral lining. Although there is no control of the cable arranging device at the time of winding, since the distance from the introduction roller is large and the introduction angle is small, the subsequent cable layers can be arranged one by one. The large electric track flat car has a long transport distance and a large input power, and uses a power cable with a large cross section and a large diameter.

This type of electric scraper must be equipped with a wide reel and cable arrangement. The cable drum powered transfer trolley is arranged with a single support and dual supports, and the drive shaft has a single shaft and a double shaft, etc., and the force is determined by the structure. The winding radius is an important parameter in the overall design of the track flat car. The spatial position of the cable drum powered transfer trolley and the design of the power unit should be considered. Another part of the reel design is the transmission of electrical energy through which electrical energy is transferred to the body.
