Description

Standard: IEC 60794; VDE 0888
CONSTRUCTION:
Optical fibers:
SM – single mode optical fibers (9/125 µm)
(G.652D, G.655, G.657A1/A2)
MM – multi mode optical fibers (50/125 or 62,5/125 µm) according to ITU-T Recommendation
Material of fibers:
a) core – Silicon glass: (SiO2) doped with Germanium Dioxide (GeO2);
b) cladding: Silicon glass (SiO2)
c) primary protection: Dual layer of UV-cured acrylate resin
Secondary protection of fibers: Filled loose polymer tube of PBT elastomer, filled with tixotropic jelly mass, loose laid fibers within tube – SZ stranded
Tube material: Polyester PBT-Polybutylene Terephtalate
Fibers and tubes designation: IEC 60304, TIA/EIA-598; DIN VDE 0888
Cable core:
Central tube: cable core is without FRP and in one tube placed max. 24 optical fibers. Cable core is dry.

Watertight element: Dry cable core (without jelly)

Belt insulation: one or more layers termoplastic or swellable tapes, helicoidally or longitudinally wrapped
Armouring of cable: strength member element of aramid fibers in 2 layers (doped with swellable powder are used as additional water and mechanical protection). Aramid fibers are wrapped with polyester tape.
Sheath ripcord: one or more ripcord placed under outer sheath
Outer sheath: HDPE – high density polyethylene, black

APPLICATION:
Self supporting for power lines (non metallic cable) are use for outdoor application, cable are waterproof, UV resistant, metal-free air hanging cable, suited for fixing on poles.
The permissible temperature range:
– during installation: from -30°C to +60°C
– during operation: from -30°C to +70°C
– during storage and transport: -40°C to +70°C
Min. permissible bending radius:
– Operation: 20D
– Fixed: 15 D (D – diameter of cable)
Tensile strength (kN): On customer’s request, depending on the span between poles.
