30% more speed

TELE-FONIKA Kable has several CCV-lines in their Bydgoszcz factory for insulating and cross-linking of medium, high and extra high voltage XLPE insulated cables. In spite of the large number of lines TELE-FONIKA lacked capacity and wanted to increase the productivity without sacrificing the cable quality. How did the company achieve 30% more production speed across its product range? 

TELE-FONIKA Kable, Poland

TELE-FONIKA Kable is the largest cable company in Eastern Europe. It is a recognized and trusted provider of copper and aluminum cables & wires, and fiber optic cables.The first Maillefer CCV-line delivered to TELE-FONIKA Kable dates back to 1985 and our long-lasting cooperation has continued ever since. 

Increased productivity

TELE-FONIKA Kable has a new, state-of-the-art high voltage CV line producing up to 3000 mm², 500 kV cables. It includes a modern Maillefer material handling system. Thanks to the Neutral Zone Postheater, they have reached speed increases of up to 30% across the product range. TELE-FONIKA Kable benefits from the increased capacity and reduced operator cost per cable kilometer.

Mr. Tomasz Draganek,
Director of the Bydgoszcz Plant,

“We have a long relationship with Maillefer, and we have many Maillefer CCV lines in our factory. The new high voltage CV line is in full operation, producing up to 3000 mm2, 500 kV cables. The Neutral Zone Postheater has significantly increased productivity. It has worked so well that we have placed an order for a second postheater for another production line”



The solution - Speed increases with the Neutral Zone Postheater

The Neutral Zone Postheater is a patent pending method invented by Maillefer. It is offered for EHV CCV lines, like the one delivered to TELE-FONIKA Kable. Using the Neutral Zone Postheater minimizes drooping of the insulation even at high conductor temperatures. This significantly increases line speed while maintaining the roundness and centricity of the insulated conductor.

A Neutral Zone Postheater together with the latest extruder screws provides real opportunities to boost productivity. For new CV lines, increased line speed is not the only alternative. With the Neutral Zone Postheater, the actual heating section can be shorter for an equivalent line speed, resulting in a reduced height of the extruder platform and lower building costs.
