Product Description
Optical Fiber Composite Overhead Ground Wire (OPGW) is an overhead ground wire containing optical fibers,
combining dual functions of an overhead ground wire and optical communication transmission.
It is primarily used for communication lines in 110kV, 220kV, 500kV, and 750kV high-voltage
power transmission systems as well as newly constructed lines. OPGW can also be used to replace
existing ground wires on traditional overhead high-voltage transmission networks, adding
optical communication channels, conducting short-circuit currents, and providing lightning
protection. Special customized structural designs are available upon request to meet specific client requirements.
Product Features
Advanced Stainless Steel Tube Technology: Advanced tube manufacturing filled with water-blocking compound provides
optimal protection for optical fibers.
Low Interference: Minimal mutual interference between short-circuit current and power grid/communication system.
Fiber Excess Length & Lay Length Control: Precise fiber excess length and cable core lay pitch ensure fibers remain
strain-free under maximum working tension.
Compact & High Tensile Strength: Compact structural design featuring high tensile strength and mechanical resistance
Easy Installation & Direct Replacement: Matching specifications with common ground wires make installation highly
convenient for direct replacement of existing ground wires.
Customizable Structural Options: Tailored layer-stranded or central-tube designs to adapt to various power line
capacities and span lengths.

Values are typical reference data taken from the official Huifiber datasheet. Confirm the final specification against the datasheet before ordering.
Huifiber OPGW (Optical Ground Wire) cable combines ground wire protection and optical fiber communication for high-voltage transmission lines (110kV-750kV)
Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.
Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.
Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
