OPGW Typical Designs of Central AL-covered Stainless Steel Tube

Optical Ground Wire (OPGW) Mainly used for power communication with accessories,relay protection,automatic transmission,installation together with high-voltage lines. 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.

 

Fiber Type: G652D; G655C;

Fiber Count: 12-144 Core

Application: for communication lines of 66KV, 110KV, 115KV, 132KV, 150KV, 220KV,400KV, 500KV, and new overhead high-voltage transmission system.

Standard: IEEE 1138、IEC 60794-4、 IEC 60793、TIA/EIA 598 A

ApplicationsAerial, Overhead, Outdoor

Main Features

1. High quality IEC607948 IEEE1138 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 lightning.
4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing a high-pressure line over 110kv.
5. Apply to the transformation of old lines.
