Copper Aluminum Steel Wire Rigid Frame Strander For LV/MV/HV Power Cables

Rigid Stranding Machine:

The machine is used for stranding copper, Aluminum. Stranding unilay and reverse concentric, round, compressed, compacted or sector shaped conductors to be used for the cable manufacturing or for the Over Head Conductors. Rigid stranding lines are ideal machine for making conductors of large size for LV/MV/HV power cables and over head conductors (AAC/AAAC/ACSR). Prepared for Bobbin Dia. 630mm to 710mm with automatic side or floor loading system at 45°as well as special systems adapted to customer need. Confuguration from 19 to 127 wire.

Equipped with contant tension control system and intelligent brake system:

By Tracking(Supersonic) the length of wire wrapped on bobbin, the length of wire remaining on bobbin will be detected and transmitted to PLC. The PLC will control the in-taking air by proportional valve and make the tension of wie constant following the length of wire remaining. Two groups controlling the tension of brake dics for paying-off to ensure the pressure on dics equal. Pneumatic brake system is controlled by intelligent brake system. When energency stop of machine, the speed signal of each cage will be trasmitted to PLC by sendsor. PLC will make calculation automatically and provide different brake force to each cage by proportional valve accordingly. Then the different cage will stop synchronized.

The convert control system to guarantee loading successfully in one time:

The trolly is controlled by converter, the operation is slow-faset-slow, it means the trolley starts slowly, moves qualicy and approachs cage slowly. It can make trolley running stable, reliable and precision. Mechanical and electrical positioning.

Equipped with motorized full security cover:

Fully covered unit ensure safe of opetation. The cover will open when Loading/unloading or stop of line. It's motorized simply

Electrical Control System:

The synchronal control system for separate motorized strander is different with other similar strander system by other makers. It's easy to operator by setting-up of all parameters on touch screen. All process parameters can be recollected. Unique pro and date collection system ensure machine running stable and realiable. The precision of lay length is less than 3% when emergency stop and less than 1% when normal stop of line (Profibus communication control).
