(OPGW OPPC ADSS) Overhead Optical Cable

(OPGW OPPC ADSS) Overhead Optical Cable

Overhead Optical Cable (OPGW OPPC ADSS) is suitable for Communication Systems.

An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable in overhead power lines. Such cable (OPGW OPPC ADSS) combines the functions of grounding and communications.

Application

Communication System

Overhead Optical Cable Type

  • OPGW (optical fiber composite overhead ground wire)
  • OPGW cables have the dual functions of ground wire with communication capabilities.
  • OPPC (optical fiber composite phase conductor)
  • OPPC cables have the dual functions’ performance functions of phase conductors with communication capabilities.
  • ADSS (all-dielectric self-supported cable)
  • ADSS cables are a kind of non-metal optical fiber cables suspended directly between two points without any supporting elements.

Central Type Stainless Steel Tube OPGW

Type

Central Type Stainless Steel Tube OPGW

Fiber Core

8/12/16/24/36/48/96

Structure

The stainless steel tube is hermetically sealed by seamless welding; the central stainless steel tube is surrounded by single or double layers of metal wires. The tube is filled with water-resistant gel. This tube provides complete protection to the fibers from longitudinal and lateral water/moisture ingress. The interstices in between the stainless steel tube and the metallic wires are filled with anti-corrosive grease for protection from corrosion.

Application

Photovoltaic / wind power plant / transmission line / substation

AL-covered Stainless Steel Tube OPGW

Type

AL-covered Stainless Steel Tube OPGW

Fiber Core

8/12/16/24/36/48/96

Structure

Optical fibers are placed in a hermetically sealed stainless steel tube covered with an aluminum layer. The central aluminum-clad stainless steel tube is surrounded by single-layer or double-layer metal wires. Good anti-corrosion performance, suitable for the highly corrosive environment, no need to use anti-corrosion grease.

Application

Photovoltaic / wind power plant / transmission line / substation

 

Aluminum Tube OPGW

Type

Aluminum Tube OPGW

Fiber Core

8/12/16/24/36/48/96

Structure

Optical fibers are placed loosely in plastic tubes embedded in a hermetically sealed aluminum tube. The aluminum tube is surrounded by single or double layers of metal wires. The structure has good corrosion resistance for its uniform materials.

Application

Photovoltaic / wind power plant / transmission line / substation
