Compact Rigid Strander For Building Wire And Control Cable Up To 169 Wires

Compact Rigid Strander For Building Wire And Control Cable Up To 169 Wires

Description

The rigid cage strander is the machine par excellence for manufacturing conductors for power cables. This the strander combines quality, productivity and flexibility compared to other stranding methods.
JLK series is built under the BEYDE brand, a world leader in rotating machines for energy cables which has supplied more than 150 rigid cage stranders to the top energy cable producers.

The rigid cage stranding and screening machine allows for the production of conductors used in aerial cables, low/medium/ high voltage cables, submarine cables, wind power cables, Milliken segments, ACRS cables and screening.

Key Features and Advantages

High Capacity & Large Section: Capable of accommodating a large number of pay-off reels, twisting dozens or even hundreds of wires simultaneously. This enables high production efficiency, making it especially suitable for high-volume manufacturing of large-section conductors and cable cores.

High Structural Rigidity:

Its sturdy metal frame design provides exceptional rigidity, capable of withstanding the immense torque and tension generated during the stranding of large-section, high-strength wires, ensuring stable operation.

High Stranding Precision: Modern rigid frame stranders are equipped with precision drive systems, tension control systems, and length counters, guaranteeing uniform lay length, compact structure, and consistent tension across all wires.

Integrated Functions: Modern machines also integrate additional functions such as pre-twist, back-twist, online diameter measurement, filling, or taping (serving).

Comparison with Tubular Stranders

The main differences between the Rigid Frame Strander and another common stranding machine – the Tubular Strander – are as follows:

Structure: The Rigid Frame Stranding Machine adopts an open-frame structure, while the Tubular Strander features a closed tubular structure.

Applicability: The Rigid Frame Strander focuses more on large-section, high-speed, and high-volume wire and cable production. The Tubular Strander is better suited for small-section production scenarios requiring high flexibility (easy specification change) or where a fully enclosed environment is necessary.

Pay-off Reels:

The Rigid Frame Strander typically uses larger pay-off reels (e.g., PN630, PN800, PN1000) to meet long-duration continuous production needs.

Rigidity:

The overall rigidity of the Rigid Frame Strander is significantly higher than that of the Tubular Strander.

The rigid frame strander, with its high-rigidity frame + multi-reel design, has become the preferred equipment for manufacturing MV/HV power cables and large-section bare wires. Its technical characteristics meet the stringent process requirements for high-end products such as new energy cables and UHV transmission conductors. Renowned cable equipment manufacturers like BEYDE offer a series of rigid frame stranders with various specifications and configurations. BEYDE's equipment demonstrates distinct advantages in reliability, production efficiency, automation level, and operational convenience, catering to diverse manufacturing requirements for power cables and bare wires across different clients.

The primary function of the rigid frame strander is to twist multiple individual wires (conductors) or strands together according to specified direction and lay length, forming larger-section stranded conductors, cable cores, or cables. Its core workflow is as follows:

Pay-off:

At its heart are one or more robust rotating metal frames equipped with multiple pay-off reels (bobbins), typically featuring tension control devices, which supply individual wires or strands.

Stranding:

The entire frame rotates at high speed, causing all mounted pay-off reels to rotate with it. Simultaneously, the central core wire (or cable core) advances linearly along the machine axis.

Forming:

The combination of the frame's rotary motion and the wire's linear advance causes the surrounding individual wires to twist tightly onto the central core at the preset helix angle (i.e., the stranding lay length).

Take-up:

The finished stranded product is wound onto the take-up reel.
