Our Tecniflex cables for fixed installation have also been designed and developed in the multicore version with an armouring braid, Tecniflex AR.
This type of armored cables is suitable for the use in an industrial environment, both as control cables and for powering electrical equipment.
The mechanical protection called “armouring” has the aim of ensuring the maintenance of these special cables performance even in critical environments and situations, such as in presence of rodents or various types of mechanical stresses.
TECHNICAL AND MECHANICAL REQUIREMENTS OF ARMORED CABLES
The conductor insulations and the outer jacket are made by a high quality PVC mixture, they are self-extinguishing, according to IEC 60332-1-2, and have good resistance to the most industrial oils and chemical agents.
The technical and mechanical requirements are:
- Bare copper conductors, class 5 according to IEC 60228
- Black numbered or UNEL PVC insulations, with or without green/yellow conductor
- Zinc plated steel armouring braid
- PVC transparent jacket TM2 type
- Working voltage 450 / 750V
The cross-sections of these special armored cables start from 2 to 34 poles with sections between 0.5 and 16 mm2.
The coverage of the zinc plated steel braid is 65%, up to 80% with reference to 2×1,5 and 7G4 cross-sections.
