Tubular Strander Type JG-630 Mainly For The Production Of Compacted And Non-Compacted Strands

1. Application

This machine is suitable for steel core aluminum stranded wire, steel stranded wire or stranded wire. The two-section integrated production process of the stranded pipe cage, small turning radius, both ends of the bearing support, can ensure stable operation and long service time.

2. Feature

2.1 Tube rotating on encircling bearing or roller.

2.2 Machine able to work in torsion or total back twist with the possibility of variable back twist.

2.3 Wire tension kept constant from full to empty payoff reel.

2.4 Wire/strand break detector for each payoff.

2.5 Pneumatic pintle equipped with safety locking system.

What it is and typical use

A tubular (tube) stranding machine forms ACSR​ and other stranded conductors by rotating a precision tube (cage) around a fixed core. It is widely used for bare copper/aluminum, steel wire, ACSR/AAAC, and can also serve as a high‑speed strander for insulated cores with an added taping head. Typical line composition includes: central payoff, tubular stranding cage, assembly die, meter counter, traction (capstan), take‑up with traverse, and PLC/HMI​ control. Machines commonly support both torsion​ and total back‑twist​ modes with variable back‑twist, constant‑tension payoff, and per‑bobbin break detection

Sizing and selection guide

Define ACSR structure and target: number of aluminum strands and steel core wires, finished OD, required lay length/pitch, and whether you need back‑twist (planetary)​ or zero back‑twist.

Match single‑wire capability: ensure max single‑wire diameter/strength​ (e.g., Al φ1.5–5.0 mm, Cu φ1.3–4.6 mm, steel φ1.3–4.0 mm​ for many high‑speed tubers) and the machine’s max stranded OD​ (e.g., up to φ15 mm​ on high‑speed models).

Set haul‑off and capstan: choose a capstan diameter​ and line speed​ consistent with your production target and pull force (e.g., line speed 20–100 m/min​ on high‑speed models; dual capstans such as Ø1200 + Ø1000 mm​ for larger ACSR).

Reel logistics: confirm PN sizes​ for in‑cage bobbins and take‑up to match plant handling (e.g., PN1250–PN2000​ common on 400–630 class machines; PN1600​ typical on 630/1+6 ACSR lines).

Control and quality: plan for PLC/HMI​ with tension, pitch, and length control; add in‑line OD/geometry​ and eccentricity monitoring as required
