China Optical Fiber Composite Overhead Ground Wire OPGW
cable,12/24/36/48 core
Description:
OPGW Cable, Optical Fiber Composite Overhead Ground Wire, also
known as Fiber Composite Overhead line. The optical fiber is placed
in the
ground line of overhead high voltage transmission line and used to
form the optical fiber communication network on the transmission
line. This
structure has the double function of ground wire and communication,
commonly known as OPGW optical cable.

Characteristics:
Stranded Stainless Steel Tube OPGW
1. High quality standards for designing, testing and producing with
grade A materials available to ensure long-term reliability.
2. Engineering support supervising and providing its own line of
accessories hardware.
3. Seal stainless steel tube superior protection to the fiber
optical to moisture and extreme environmental conditions such as
lighting
4. To construct OPGW must cut power,resulting in greater loss,thus
OPGW must be used in constructing high pressure line over 110kv.
5. Apply to the transformation of old lines.
Central (Al-covered) Stainless Steel Tube OPGW
1. High quality standards for designing, testing and producing with
grade A materials available to ensure long-term reliability.
2. Engineering support supervising and providing its own line of
accessories hardware.
3. Larger tensile strength and fault current capacity to reach a
better balance of electrical and mechanical performance.
Aluminum Tube OPGW
1. Good anti-corrosion performance.
2. Material and structure are uniform,good resistance to vibration
fatigue.
3. Short circuit current has small effect on the optical fiber
