Fiber Optic Cable for OPGW Power Electric Transmission Line

Publish Date 2015-11-25
Introduction
The stainless steel tube is surround/stranded by single/double/three layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.There are three main designs: Stranded Stainless Steel Tube OPGW, Central Al-covered Stainless Steel Tube OPGW,  Aluminum Tube OPGW.
Characteristics
1.For :  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;
Apply to the transformation of old lines.   

2.For :  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.

  3.For :  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 transmission properties.
Good anti-lightening performance.  

Standards
Comply with standard YD/T 1997-2009,ICEA-596,GR-409,IEC 60794,ETC.
