J-H(St)H …Bd VDE 0815

PRESENTATION

These cables are suitable for indoors telecommunication fixed installation. These cables are halogen free and flame retardant. They are used in locations with fire hazard to reduce damage in case of fire.

STANDARDS

VDE 0815 standard.

CABLE MANUFACTURE

1- Conductors :

Each conductor consists of a solid wire of annealed, grade A copper, having a diameter of 0,6 mm or 0,8 mm.

2- Insulation :

Each conductor is insulated with a FRNC compound

3- Standing :

- Four conductors to form a star quad.
- Five quads to form a bundle.
- Bundles assembled in layers.

4- Wrapping :

A polyester wrapping tape is applied over the cable core.

5- Screen

Over the wrapped core is applied a plastic coated aluminum foil.

6- Drain wire

The drain wire is an annealed copper having a diameter 0,6 mm for cables with conductor diameter 0,6 mm and 0,8 mm for cables with conductor diameter 0,8 mm.

7- Sheath

The sheath is an FRNC compound.
