?Product description of opgw overhead optical fibre cable

 

1.The central stainless steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs.

 

2.The stainless steel tube is stranded by double or three layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.

 

3.The central Al-covered steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.Al-covered Stainless Steel tube design increases the cross section of AL,to reach a better fault current and lightning resistance performance.Apply to the transmission line which requires small diameter and large fault current.

 

4.The Aluminum tube 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.
Feature:

1. Stainless-steel optical fiber unit of central loose tube or layer stranding structure 

2. Aluminium alloy wire and aluminium clad steel wire armored

3. Coated with anticorrosive grease between layers

4. OPGW can support heavy load and long span installation

5. OPGW can meet the ground wire's requirement of mechanical and electric by adjusting proportion of steel and aluminium

6. Easy to produce the similar specification of exist ground wire can replace the exist ground wire

Application:

1. OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines. Its applications are:high pressure over 110kv, with a longer span (usually over 250M)

 

2. Easy to maintain, easy for line span, its mechanical property can meet a big line span

 

3. Outer OPGW is metal armoring, with no influence for high pressure electro-corrosion and degradation

 

4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in

 

constructing high pressure line over 110kv
