APPLICATION

The cable is determined for outdoor aerial lines, for building of telecommunication networks, installation of LANs and cable TV networks and information systems in power engineering and industry. The cable can be used for outdoor mounting, for aerial lines between buildings. Typical gap distance between two grips is from 80 up to 300 m. Also cable for greater gap distances can be supplied by agreement.

PROPERTIES

• FULL DIELECTRIC SELFSUPPORTING CONSTRUCTION
• MAX. NUMBER OF FIBRES 48
• MAX. NUMBER OF CORES 6
• ARAMIDE STRENGTH ELEMENTS
• PE JACKET
• FOR GAP DISTANCES FROM 80 UP TO 300 M

The design of cables allows high tensile loads. The filled cores provide very good longitudinal waterproofing. Maximal gap distance depends on wind conditions.

PACKING, DELIVERING, STORAGE, TRANSPORT

Optical cables are supplied twisted on wooden or metal drums with diameters of 500 to 1500 mm, shorter lengths twisted to coils.

To every supplied length is attached test protocol and tag with these data:

- producer´s mark
- cable identification
- cable length in meters
- production date
- stamp of quality control

The whole cable can be marked with description on a jacket on request of a client.

Cables can be stored in general in open-air area or in warehouses. They cannot be exposed to thermal radiation and they cannot be stored together with flammable liquids or solvents or with products containing them.

It is necessary to assure that cables are not damaged by mechanical or other effects by transport.
