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.

| ADSS and OPGW cable |
Characteristic of opgw cable:
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 lightening
4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing
high pressure line over 110kv;
5. Apply to the transformation of old lines.
