OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. It’s working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.

The OPGW consists of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure. 

1. Easy to maintain, easy for line span, its mechanical property can meet a big line span
outer OPGW is metal armoring, with no influence for high pressure electro-corrosion and degradation

2. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv

3. OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines

4. Its applications are: high pressure over110kv, with a longer span (usually over 250M)

According to the technical conditions, we can get the required products without changing the cable structure and composition ratio of aluminum steel section.
Compared with aluminum tube structure, the OPGW cable with thin-walled stainless steel tube structure can bear greater lateral pressure and impact. Stainless steel with low conductivity, high strength, and good corrosion resistance makes the fiber in good protection.
Stainless steel tube filled with ointment can prevent the moisture or water infiltration, and let the cable have a good temperature characteristics through adjusting the fiber length.
Aluminum clad steel wire with High-strength and low-conductivity can bear the load of OPGW dead weight and external load. According to charge skin effect principle, the dredge of overload or fault short circuit current is conducive to the protection of the optical fiber.
Fiber optic cable and conventional overhead ground wire has similar mechanical and electrical characteristics. The dual function of optical cable facilitates the replacement of old ground wires, and the design and installation of the new ground wires.
The well-controlled fiber length ensures the cable can withstand high load and large span.

Packaging Detail:  Wooden drum or iron wooden drum

Delivery Detail: 30days after confirmation of order and payment

In 1995, first test run of Huiyuan ADSS cable put into operation in Sichuan power grid.  After nearly 20 years test, the line still runs safely, which creates the longest run record of domestic ADSS cable.

In 1996, the first domestic ADSS cable with high-voltage electrical corrosion sheath ran safely on the 220KV line till so far.

After years of development, Huiyuan has become a special optical cable provider in the western region and an influential company in China. Its featured products have four series, including power fiber optic cable (ADSS, OPGW, OPPC); micro air blown cable, fiber optic unit and micro air blown cable tube; various types of sensing cable and detection cable; Lp user oriented fiber and optical fiber ribbon.
