Recently, the DTE-1250D bunching machine manufactured by Jiangsu Handing has successfully passed the in-house complete machine test. All performance indicators meet the design specifications, laying a solid foundation for formal delivery and commissioning at the customer’s site.

Core Parameters

This bunching machine adopts an integrated control system. It supports processing of copper, aluminum and aluminum alloy conductors, with a maximum capacity for 7-strand concentric stranding. The maximum processing cross-section is 50 mm² for copper conductors and 70 mm² for aluminum conductors. It is equipped with a closed-loop constant tension control system and an external rotary compacting die, as well as multiple safety devices including wire breakage protection, overload protection and safety door interlock.

Equipment Function

The DTE-1250D bunching machine is mainly used for the conductor stranding process of power cables and control cables. It twists and compresses multiple single wires into shape to realize integrated processing of concentric conductor stranding. Conductors produced by this machine feature uniform lay length and stable outer profile, which are well compatible with the subsequent insulation extrusion process. It meets the mass production requirements of conductors in various specifications and enables quick changeover for different cable sizes.

Core Advantages

Low vibration and low noise at high operating speeds with outstanding stability for long-duration continuous operation. The closed-loop constant tension control effectively prevents conductor stretching, wire skipping and wire breakage. Compacted conductors achieve excellent roundness and high consistency of finished products. The lay length can be set directly on the HMI with automatic calculation and adjustment. Spool change and specification commissioning are simple and fast, greatly reducing changeover downtime. Complete safety interlock protection with sensitive braking response effectively eliminates production risks. In addition, one machine is compatible with multiple conductor materials for strong versatility, suitable for the production of mainstream medium and low-voltage cable conductors.

This test has verified the process stability and continuous production capacity of the equipment.
