Cage Stranding Machine

(1) 630 Cage Strander

Application Scenario

This equipment is mainly used for cabling of insulated cores for control cables, signal cables and small-sized plastic power cables, as well as non-metallic wrapping operations.

Performance Parameters

· Diameter of insulated single wire: 1.8~12 mm (minimum conductor cross-sectional area: 0.5 mm²)

· Rotation speed (stepless adjustable): 6-bobbin: 10~90 r/min 12-bobbin: 9~80 r/min 18-bobbin: 9~72 r/min

· Equipped with synchronous stranding function and synchronizing tubes installed on the stranding cage. The inner diameter of synchronizing tubes fits wire diameters from 1.8 mm to 12 mm. 6 synchronizing tubes for 12-cage version, 12 synchronizing tubes for 18-cage version.

Functional Features

· Planet gear type back-twist structure realizes 100% mechanical back twisting.

· Hysteresis tension control: regulated by current signal. Each bobbin frame is independently controlled via PLC closed-loop control, maintaining constant tension from full spool to empty spool.

· Fully enclosed sound insulation protective cover, with door limit switches fitted on all access doors.

(2) 800 Cage Strander

Application Scenario

Designed for stranding and armoring of non-metallic rods and metal wires, mainly including steel wires, plastic-coated steel wires, aluminum-clad steel wires, aluminum alloy wires, steel tube optical fiber units and other similar materials.

Performance Parameters

· Single wire diameter: 1.5~6.0 mm

· Cage configuration: 800 model / 16+24+56 cradles

· Rated rotation speed (stepless adjustable): 16-bobbin: 35 r/min 24-bobbin: 30 r/min 56-bobbin: 25 r/min

Functional Features

· Back-twist mechanism adopts planetary gears and synchronous pulleys with independent parallel back-twist design. Hardened ground gears are applied for long service life and low running noise.

· Double-end support structure for the main stranding cage ensures stable operation and high efficiency.

· Hysteresis tension control system with current-based regulation. Independent PLC closed-loop control for each bobbin frame keeps tension consistent during the entire unwinding process.

· Drive system: main motor connected with shift gearbox + hardened gear reducer + gear box assembly. This structure buffers direct impact on the gear box, extends gear service life, and delivers reliable and stable power transmission.

· Built-in synchronous stranding function with synchronizing tubes mounted on the stranding body.
