High Impact Wire And Cable Machinery , Production Line For
Corrugation Sheath Cable
This tube welding and corrugating line is specially designed to
produce aluminum corrugation tube
sheath to middle and high voltage cables and other cables with
special requirement. The helical
corrugation tube sheath is gas and liquid proof which strengthens
high impact and pressures stability while ensures bend ability of cable. As the advantages like low
consumption, high accuracy and high efficiency is quite obvious over traditional cable armouring
methods, this producing line is being adopted by vast HV cable manufacturers and communication cable
The producing takes metal strip as basic material and follows tube
forming, seam welding and
corrugation process route. The whole line utilises PLC control
system to maintain the producing with high efficiency and low defects, meanwhile requiring less manpower
involved. The whole line works in synchronization as following.
Cable core bobbin and strip bobbin are lifted on each pay-off
stand. The design of the strip pay-off
depends on the packaging of the metal strip supply.
The cable tip gets dragged into forming machine and keeps passing
along the center line. Oxidized aluminum strip margin gets cut off before it enters into forming
machine for a better welding quality.
3. Strip Forming
The cable keeps forwarding while the strip keeps forming into a
tube shape around the core cable.
When the cable is well arounded with the aluminum tube, they enter
into the welding machine
simultaneously to get the seam welded. There is an electromagnetic
detection device inspecting
The caterpillar works as dragging force of combined cable and
sheath tube as well as pushing force for them enter into corrugation machine.
6. Tube Corrugation
After welding, the core cable is actually protected already by the
flat tube. But flat tube is not tough
enough as corrugation tube in against pressing, shocking, striking
damages etc. Then the core cable
with welded aluminum tube is sent into corrugation machine. The
corrugation pitch is adjustable
according to different mechanical requirements
7. Put away the completed cable with corrugation tube into giant
Main parts of the complete line as following list.
1. Date setting is thorough touch screen, it’s simple and easy
2. Control utilizes PLC to maintain high speed and high accurate
3. Position of welding head is adjustable in three directions
4. Ten groups of pressing cylinders included in caterpillar ensures
a powerful drag
5. Low producing consumption and less manpower involvement
