OPGW Central Tube Optical Ground Wire 12-48 core singlemode fiber optic cable

Features:
1. High quality standards for designing, testing and producing with grade A materias 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.
