Cage Screening Rigid Stranding Machine Without Backtwist

Rigid Cage Stranding And Screening Machine Without Backtwist

1. The rigid strander is the machine par excellence for manufacturing power conductors. It is the strander that combines quality, productivity and flexibility compared to other stranding methods. We have developed a wide range of ancillary equipment such as semi-automatic loading systems, compacting heads, pre-formers, post-forming heads, capstans, take-ups that enables us to offer a complete catalogue of solutions for:

Stranding of soft Cu and AAC bare round conductors, either straight, pre-spiralled sectoral or Milliken segments.
Stranding of aerial bare conductors in various constructions: AACC, ACSR and other similar designs, with round or trapezoidal wires.
Multi-wire screening of medium and high voltage conductors
Armouring with Galvanized Soft Steel Wires.
MACHINE PERFORMANCE

Max. Linear Speed: 71 m/min

2. A driven pintle system, independently motorized by AC motors, which allows the operator to unload/load one bobbin at a time. The transmission is mechanically irreversible by a high ratio worm reducer to secure safe locking.
An automatic diameter control feature lets the machine speed up when the rotating mass decreases which in turn increases the average speed of the rigid stranding line
UPS and Dynamic Regenerative Drive System to bring the entire machine to a controlled stop during a power failure without product damage.
Safety PLC with Remote I/O for ease of maintenance and troubleshooting.

3,.Gear transmission to minimized noise
Auxiliary motor speed reducer for optimized cage loading / unloading
Rugged monolithic rotor construction provides mechanical reliability and excellent performance under the most extreme conditions
Semi - Automatic Loader. Semi-automatic unloading / loading device (one per cage) without the intervention of the operator
The Compacting Heads are specially designed for tight tolerances required for the manufacture of bare sector elements for Milliken conductors
Wire tension settable from HMI
Wire tension kept constant from full to empty reels
Wire break detector for each reel
Strands can be produced in a single or multi-pass by connecting the cages in tandem mode

4.The machine can be equipped with a special forming plate for trapezoidal wires for the production of ACSR/TW overhead conductors.
Pre-formers for Al alloy production and steel armouring.
Post-formers for aerial strands.
Binding and longitudinal taping heads for water blocking tape applications.
The line can be equipped with various kind sof loading devices, depending on the available space: side trolleys or hydraulic platforms.
For screening applications there are available a full range of eccentric, concentric and tangential taping heads for plastic, copper, aluminum, and steel tapes
