Description

Description

User benefits:

AXQ/TXXI is a halogen free, XLPE-insulted and HFFR sheathed cable with circular, stranded aluminum conductor. The cable is designed according to SS 424 14 18. The conductors have resistance according to IEC 60228 class 2. The sheath is marked "NEXANS GS AREA mm2 1kV Ds2d2a2 year+month". AXQ/TXXI meets the requirements for flame class Dcas2d2a2 according to CPR.

 

Lifemark(TM) recycling marking

The external surface of the outer sheath is embossed with a text which specifies all components in the polymers and prepares the cable for future recycling.

Quality system

Designed, manufactured and tested in accordance with ISO 9001.
