AERIAL CABLES

ALL DIELECTRIC SELF SUPPORTING METAL FREE CABLES

FEATURES/ADVANTAGES

Light weight permits larger spans.

Ideal for direct installation on poles and buildings.

Meets IEC 60794,EIA/TIA,ITU T,EN 187000, RUS 1755.900 & Telecodia GR -20 Internationa standards.

Suitable to install upto 125 KV electrical lines.

( A )UNITUBE DESIGN

Loose tube containing fibres and jelly is centrally located. The strength members (FRP) are embedded in the HDPE sheath. A layer of non metallic strength member (aramid yarn) between the inner and outer HDPE sheath provides the extra tensile strengths required for aerial installations.

C) MULTITUBE DESIGN DOUBLE SHEATH CONSTRUCTION

Loose tubes containing fibres and jelly are S-Z stranded around a central strength member.A layer of non metallic strengths member (aramid yarn) provides the extra tensile strengths required for aerial installations on poles.

D) FIGURE - 8 DESIGN:

The loose tubes containing fibres and jelly are S-Z stranded around a central strength member.A bunch of stranded steel wires are sheathed with core to make the figure -8 construction, ideal for aerial installation.
