Stainless steel tube as optical unit in the center of the structure, the outer layer is in a certain pitch-diameter ratio and a certain number of aluminum-clad steel wires or aluminum alloy wires are stranded.

Stainless steel optical unit is in the inner position. Compared with the central stainless steel tube, larger cable diameter and larger capacity of the optical fiber. It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection.

Product feature  The fiber is well protected by mechanical and thermodynamics.  Excellent capability against side and outstanding short circuit current capacity.  Optical fiber is not under stress when it is subject to the maximum permissible stress.  Layer-stranded single wire provides excellent mechanical and electrical properties.  Match with common ground wires.
