Lines for the production of rubber-insulated conductors and cables, and particularly CV lines for the production of medium, high and extra-high voltage cables, are the focus of TROESTER's range of manufacturing machinery.

The Triple Cross Head enjoys an outstanding reputation, with the result that an ever increasing number of lines - including those of competitors - are being fitted with this extrusion head.

TROESTER has also patented its own unique design for CV lines: the TWINROT system. This comprises two rotating belt-type caterpillars with a braking-tension function in the catenary line, allowing adherence to excellent tolerances in the production of cables up to 500 kV. The TWINROT system thus permits the production of high voltage cables on catenary lines, which otherwise would have to be produced in tower systems, or by expensive MDCV systems.

These technical advantages make TROESTER one of the most prominent suppliers in the field of power cable production machinery. In addition to its CV systems and to satisfy market requirements, TROESTER offers a silane-based system for the production of medium-voltage cables.

Continuous refinement and new developments guarantee the latest production techniques for the insulation and sheathing of LV, MV, HV and EHV cables with various thermoplastics and elastomers.

The excellent results produced by extrusion technology, coupled with optimal control and regulation systems characterize TROESTER as a competent manufacturer of complete systems as well as individual machines (caterpillars, capstans, accumulators, winders) in the cable sector. The company's extensive know-how provides all customers with flexible options regarding the retrofitting and conversion of existing systems with TROESTER machines, through to the implementation of new cable system technologies.

• Extruders with high outputs, optimally engineered to the process-specific requirements of each system;
• Modern material management (storage, drying, conveying and precision feeding / feed equipment for all materials);
• Use of a triple cross head (successfully used in over 100 lines) to achieve excellent cable tolerances and the option of integrating conductor pre-heating;
• Reduced costs and times for machine downtime, improved product quality and shorter cycle and change-over times;
• Leading-edge automation designs
