In the ever-advancing world of power cable manufacturing, process optimisation and quality assurance are key. A notable new development is the introduction of the By-Product PreFilter – a critical component designed to improve efficiency in nitrogen gas circulation systems.

The PreFilter plays a vital role in maintaining the performance and cleanliness of the gas loop. It effectively collects and reduces the build-up of residue, ensuring smooth operation and safeguarding cable surface quality throughout the production process.

Constructed as a pressure-rated vessel, the unit comprises a container body with multilayer chambers, integrated cooling systems, pipework, instrumentation, and valves. This robust assembly is highly efficient in collecting by-products that could otherwise compromise performance.

A sequence-controlled valve automatically releases liquid waste into a designated collection tank, and the unit can be easily disconnected for cleaning – reducing downtime and supporting streamlined maintenance.

The benefits of incorporating a PreFilter into your production line are substantial:

  • Longer running lengths
  • Extended intervals between maintenance cycles
  • Reduced surface defects on finished cables
  • Optimised heat exchange within the gas cooling circuit
  • Efficient removal of by-products

By ensuring a consistently clean gas environment, the PreFilter enhances both productivity and end-product quality – helping manufacturers meet the increasingly stringent demands of the global power cable market.

New in Fibre Optics- OEL 42 – FO Line for Drop Cable

This line configuration expands the fibre optic portfolio for indoor cable applications. It features well-proven technology and innovative capabilities. The line produces all fibre optic indoor cables, including tight buffers, simplex/duplex, drop cables, and distribution cables. The high-speed fibre pay-offs handle bare fibres, tight buffers, and even reinforced elements such as FRPs and aramid yarns.

The extruder’s high output provides homogeneous and linear flow with all plastic materials used in FO cable production. The brand-new TM1250 take-up operates with a wide range of reels and cables, while maintaining a compact footprint. All components can be integrated with existing machinery to transform any loose tube line into a flexible, multipurpose line.

Benefits

  • Flexible line configuration for different FO cables, including drop cable
  • Well-proven extrusion technology
  • Space-saving take-up for wide reel and product range
