REFERENCE STANDARDS

UTE C 93-526 and UTE C 93-527-2

STRUCTURE

1- Conductors :
Each conductor consists of solid copper having a diameter of 0.4, 0.6 and 0.8 mm

2- Insulation of conductors :
Conductors are insulated by a solid polyethylene layer.
The insulator is direct and such thick so as the electric specifications are respected.

3- Stranding :
- Element of cabling: insulated conductors are assembled in Star Quads
- Cabling elements:
· Quads are assembled in concentric cables having a capacity of 8 pairs, 14 pairs and 28 pairs.
· Cables with 56 pairs are assembled in basic bundles of 14 pairs
· Cables having a capacity higher than 56 pairs are assembled in basic bundles of 28 pairs

4- Core wrapping
A dielectric polyester tape is applied over the cable core.

5- Screen
Over the cables core cover is applied an aluminium tape.

6- Drain wire
The Drain wire consists of tinned copper and has a diameter of 0.5 mm.

7- Outer sheath
The sheath consists of low density polyethylene. It is black and contains 2.5 +- 0.5 mm of carbon black. It is complying with the European standards requirements EN 50290-2-24.
