Optical Fiber Cable With Cross-Section for OPGW
Optical Fiber Cable With Cross-Section for OPGW
OPGW (Optical Ground Wire) cable is used in power transmission lines for both protection against lightning and data transmission, meeting the demand for high-capacity communication. The ground fiber optic cable itself is an insulator and is immune to power transmission line and lightning induction, external electrical noise and crosstalk.
Typically OPGW cables contain single-mode optical fibers with low transmission loss, allowing long distance transmission at high speeds. The outer appearance of OPGW is similar to aluminium-conductor steel-reinforced cable (ACSR) usually used for shield wires.
1. Central Tube Optical Ground Wire (OPGW)
The Central Tube optical fiber 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.

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.
