Accordingly, when the cable drum design, we should consider the following factors:
Cable specifications and types:
1.Cable sectional area was from 1.0 to 240mm2, the cable diameter directly influences the axial dimension of the reel and power requirements. When cable section is more than 35 mm2, should not choose the non-electric drum (counterweight can be extended to 50mm2), flat cable can only choose axial single reel. Cable should be YCW type (power cable) and CEFR type (such as control signal cable), softer and it has a certain tensile strength. The outer diameter of the cable and single weight makes to be accurate.
2.Coiling length
The coiling length affect radial dimension of the reel and the power demand, the longer length is, the higher requirements for power.
Non-electric cable winding drum is difficult to accomplish long reeling trip.
Ground power berth also directly affect the selection of cable drum, common berth has end power and middle power supply. Neutral power supply can't choose non-electric magnetic coupling (JQC series).
