Stranded Stainless Steel Tube Optical Fiber Ground Wire OPGW

Description

Optical fiber ground wire is a type of cable structure with an optical transmission composite and overhead ground wire for power transmission. It works in power transmission lines both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and short circuit currency conduction. The optical fiber ground wire consists of stainless steel tube optical unit, aluminium cladding steel wire and aluminum alloy wire. It has layer stranding structure. We can design the structure according to different environment conditions and customer’s requirements. This structure has the double function of ground wire and communication, commonly known as optical fiber ground wire.

1. Central Tube Optical Ground Wire (OPGW)
The Central 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. are the most widely used cables ,their esign is fully adapted to the most common electric line needs.

2. Stranded Optical Ground Wire (OPGW)
The Stranded Optical Ground Wire (OPGW) is stranded by double or three layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.

Specification

3.Characteristics

Stranded Stainless Steel Tube OPGW

• High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability.
• Engineering support supervising and providing its own line of accessories hardware.
• Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lighting
• 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.

Central (Al-covered) Stainless Steel Tube OPGW

• High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability.
• Engineering support supervising and providing its own line of accessories hardware.
• Larger tensile strength and fault current capacity to reach a better balance of electrical and mechanical performance.

4.Aluminum Tube OPGW

• Good anti-corrosion performance.
• Material and structure are uniform,good resistance to vibration fatigue.
• Short circuit current has small effect on the optical fiber transmission properties.
• Good anti-lightening performance.
