How to making pivot cable?
1. What is pivot cable?
It's used to deliver power to center-pivot irrigation systems. Copper conductors are totally insulated and protected against the weather thanks to an outer jacket made of black sunlight resistant polyethylene, offering an excellent moisture resistance. It's available in 7wire, 9 wire and 12 wire.
2. What structure of pivot cable?
Specifications will be to be able to produce 11 core, 9 core, and 3 core with CAT5 cable.
3. What machine for final twisting process?
Planetary Strander: It can be seen that in the final twisting process, due to the different diameters of the insulation wires and their larger division, the same size of wire reels cannot be used, and the twisting cage of the machine cannot be in the same shape. At the same time, the process requires a one-time twisting to complete all steps, and only planetary type cable laying machines are most suitable.
4. What machine model of planetary stranding machine?
JLY-630X3+400X9: 630mm reel for three big cable more 2mm diameter. 400mm reel for small cable 0.5-3mm diameter.
JLY-800X3+630X6: 800mm reel for three big cable more 4mm.
Using different structures of twisted cages based on the diameter of the cable.

6. What other useful of this machine?
The structure of new energy charging station cables is similar to PIVOT CABLE, and they are also twisted with insulated wires of different sizes and diameters.
7. Auxiliary machines:
During the manufacturing process, non-metallic and metallic shielding is required, while filling devices are required to maintain the cable's shape. At this time, in addition to adding a filling device to the stranding cage, a separate wrapping device is also required. Common ones include tangential wrapping and concentric wrapping, which are selected according to the material of the wrapping tape.
