Zenith Weldaids Tubular Stranding Machine

the tubular stranding machine consists of bearing stands made of welded steel for the tube bearings. Up to reel size of 630mm .the stranding rotor is built up from welded tubes with wire guidings outside the tube. The reels are held in cradles, which are positioned inside the tube. A light beam along the complete length of the machine monitors, if the pneumatically (optional)operated reel-pintles are securely closed and the cradles are in safe condition. The machine is equipped with wire break detectors for each segment, pneumatic disk-breaks and individual drives for the stranding rotor, the capstan and the take-up. The operator's desk gives full control over parameters like rotor-speed, lay-length and production length.

it is used for the production of: copper, aluminum, aluminum alloy strand, overhead strands
