How to Choose a Sheathing Extrusion Line for LAN Cable Production

The outer sheath affects more than a LAN cable’s appearance; extrusion consistency and sheath concentricity are also important quality considerations. When evaluating a Sheathing Extrusion Line, buyers should compare actual production speed, material compatibility, and tension control rather than relying on headline machine speed alone.

LINT TOP’s SJ65/25 model supports PVC, PE, and LSZH/HFFR materials, with a maximum structural speed of 150 m/min and an actual production speed of up to 100 m/min. Its high-speed screw and adjustable eccentric crosshead are designed to provide stable output and uniform sheath dimensions. The line also includes cooling, traction, pay-off, take-up, and tension-control systems to support continuous production. An optional longitudinal wrapping device allows aluminum foil Mylar tape or Mylar tape to be applied for suitable cable designs.

Before investing in a Sheathing Extrusion Line, confirm your cable dimensions, target output, reel sizes, and required sheath concentricity with the supplier. Ask for trial-production results using your own specifications, as well as details of installation, commissioning, and acceptance testing. Matching the equipment to actual production needs helps avoid unnecessary capacity costs while supporting consistent finished-cable quality.

How to Choose a Rigid Frame Strander for High-Quality Cable Production

For large-section copper and aluminum conductors, stranding quality affects cable performance and production efficiency. A Rigid Frame Strander with individual motor drives offers an alternative to traditional ground-shaft transmission, reducing mechanical complexity, operating noise, and maintenance demands.

Each cage and capstan has a separate motor, allowing stepless stranding-pitch adjustment to accommodate different conductor designs. Automatic bobbin loading and unloading, together with pneumatic tension control, can shorten changeover time and maintain more consistent wire tension as bobbins empty.

When evaluating a Rigid Frame Strander, compare conductor sizes, cage configuration, achievable pitch range, and loading automation. These practical factors help determine whether the machine fits your production requirements and long-term operating goals.
