OKGT-c with aluminum clad steel tube

Fiber optic cable incorporated in ground wire OKGT-c for suspension on overhead power line support with voltage 110 kV and higher.

Application:

Сable is designed for suspension on overhead power line support with voltage 110 kV and higher. It performs two functions: to transmit information and to protect the phase conductors from a lightning strike, which may damage the transmission system. This design op OKGT-c cable is used in areas with high corrosion activity.

  1. Optical fiber
  2. Stainless steel loose tube filled with hydrophobic gel
  3. Aluminum jacket of steel loose tube
  4. Stranded aluminum clad steel wires and/or aluminum alloy wires

DESCRIPTION:

An optical ground wire with aluminum alloy wires and/or aluminum clad steel wires stranded over a jelly-filled optical unit. There are one or more layers of armoring wires. The first layer is replaced by a layer of aluminum applied to a steel tube. There are one or more layers of armoring wires. In case the number of fibers exceeds 12 ring marking is used and/or bundling with identification yarns.
