2. Large working range
The operation range after the cable car and the high-voltage telegraph pole are connected for one time is as follows: 600-1000 m (300-500 m working range of the cable car on the left and right of the utility pole).
3. Long service life of cable
Because the power supply cable is thicker (the outer diameter is about 100mm), the mass is larger (the mass per meter is about 15kg), the step fall is large (the maximum height is about 80m), when the cable is placed, if no traction rope exists, the cable is pulled by manpower only, the cable is stressed greatly (the gravity is more than 1 ton when the length of 80m is long), the cable can be deformed and extended, in addition, the cable can not be rubbed with the wall surface of the step in an avoidable way, the damage of a cable sheath (an insulating layer) is easily caused, the service life of the cable is shortened, the maintenance workload is increased, and even the cable is.
Because flexible arm and cable guide component have been add to this device, when the cable was transferred from high step, the cable atress was little, and can avoid the friction of cable and step wall, can not cause the damage of cable. Therefore, the service life of the cable is long.
4. High working efficiency
The cable winding and unwinding device is convenient to operate, flexible to move (remote control) and high in working efficiency.
5. Low labor intensity
Manual cabling is high in labor intensity, time and labor are consumed, and safety is extremely poor. The cable winding and unwinding device lays cables, is convenient to operate (remote control), not only has low labor intensity and can greatly liberate labor force, reduce the number of personnel, but also has high efficiency and work safety.
