OPGW with PBT Tube

The PBT Loose Tube Optical Ground Wire (OPGW) is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. Good anti-corrosion performance.Material and structure are uniform, good resistance to vibration fatigue.  

Product Name: PBT Loose Buffer Tube Type OPGW

Fiber Type:  G652/G655

Fiber Count: 2-72 Core

Applications: Reconstruction of old power lines and low voltage level lines. Coastal chemical industrial areas with heavy chemical pollution. 




Package & Tansportation

OPGW Description:

1. OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire.

2. OPGW cable is suit for installation on new power lines with double function of ground wire and communication, especially for installation on normal voltage and extra high voltage power lines. OPGW can replace conventional ground wire of old power lines with increasing fiber communications function.

3. OPGW cables conduct short circuit current and provide lighting resistance.

4. OPGW cables are usually two structures. The central tube OPGW cable can obtain maximum optical fiber excess length in a smallest steel tube. The diameter of stainless steel tube is bigger than that of ACSR wire and aluminum alloy wire. The stainless steel tube is placed in the center of the stranded structure of the OPGW cable. Stranded OPGW cable can obtain secondary excess length; the diameter of stainless steel tube is consistent with diameter of aluminum alloy wire.

Structure Design:

opgw -pbt


Reconstruction of old power lines and low voltage level lines.
Coastal chemical industrial areas with heavy chemical pollution.

Main Features: (addition to the features of stainless steel tube OPGW cable)

  1. Can meet high electrical performance requirements, and have excellent corrosion resistant performance.
  2. Applicable to coastal areas and areas with heavy pollution.
  3. Short-circuit current has little effect on the fiber.

Applicable Voltage Range:

Power lines with voltage level of 220KV and above.
