Fiber Optic
Closures

High Quality Fiber Optic Closures made in Austria.

Fiber Optic Transition Closure Upright Installation

for OPPC up to 145kV

Features

  • NBG’s OPPC transition closure is suitable to connect max. 2 OPPC’s up to 96 fiber count with a fiber optic cable.
  • The closure consists of a top and a bottom closure. The fibers to connect the top and bottom closure, are preinstalled inside the insulator.
  • Thanks to the integrated current shunt, which guarantees low ohmic resistance, when using 2 OPPCs
  • The load current will not run through the closure body, when using 2 OPPCs.
  • The position of the OPPC input can be changed on site easily

Fiberoptic Inline Closure

for OPPC up to 145kV

Features

  • NBG’s OPPC inline closure is suitable to connect 2 OPPC’s up to 48 fiber count.
  • Typically mounting place is the current loop of the OPPC on a tension tower.
  • The integrated current shunt, guarantees low ohmic resistant.
  • The load current will not run through the closure body.
  • Due to small outer diameter influences of wind are minimized.
