Product Description

Applications:
Ideal for replacing existing ground wires and upgrading aging transmission lines.
Suitable for use on lower-grade lines such as GJ50/70/90, among others.
Main Features:
Compact cable diameter and lightweight design minimize additional load on towers.
Centralized steel tube construction prevents secondary mechanical fatigue damage.
Offers low resistance to lateral pressure, torsion, and tensile forces (single-layer structure).
Remarks & Test Descriptions:
To facilitate cable design and accurate pricing, please provide the following essential information:
A. Voltage level of the power transmission line
B. Required fiber count
C. Cable structure diagram and overall diameter
D. Required tensile strength
E. Short-circuit current capacity
Type test
Type testing may be exempted if the manufacturer provides certificates for similar products tested by an internationally recognized and independent testing organization or laboratory.
If type testing is required, it will be conducted based on a mutually agreed-upon test procedure between the purchaser and the manufacturer.
Routine test
Optical attenuation coefficients are measured on all production cable lengths in accordance with IEC 60793-1-CIC using the backscattering (OTDR) method.
Standard single-mode fibers are tested at wavelengths of 1310 nm and 1550 nm, while non-zero dispersion-shifted (NZDS) fibers are tested at 1550 nm.
Factory test
Factory acceptance testing is performed on two cable samples per order, witnessed by the customer or their representative.
The quality requirements and evaluation criteria are based on applicable standards and pre-agreed quality plans.

Packaging Requirements:
- 1:All cables shall be wound on treated wooden spools that are not returnable
- 2:Cable ends must be firmly secured to the spool and protected with waterproof shrink caps
Each spool must contain the following:
A protective outer layer of plastic wrapping
Reinforcing wooden slats to ensure stability
At least 1 meter of free cable end reserved for testing
A standard spool length of 3000mm (with a permissible tolerance of ±2%)
Cable Identification:
The outer jacket must display:
- 1、Unique sequential numbering every 1m (±1% variance permitted)
2. Additional repeating markings at 1-meter intervals must include:
Product code and fiber count
Manufacturer identification
Production date (month/year)
Total cable length
Standard Packaging Dimensions:
| Length | Container | Size (L×W×H) | Net Mass | Total Mass |
|---|
| 2 km | Wood spool | 90×75×90 cm | 156 kg | 220 kg |
| 3 km | Wood spool | 100×68×100 cm | 240 kg | 280 kg |
| 4 km | Wood spool | 109×75×109 cm | 300 kg | 368 kg |
| 5 km | Wood spool | 129×72×129 cm | 400 kg | 480 kg |
Technical Reference:
- 1、 Standard cable diameter: 10.0mm
- 2、Maximum span distance: 100m
- 3、Contact sales team for complete technical specifications
Spool Marking Standards:
Permanent markings (minimum 25-30mm height) must appear on both sides of each spool:
- 1、 Company name and trademark
- 2、Contained cable length
- 3、Cable specifications (type/fiber count)
- 4、Winding orientation
- 5、Weight measurements (gross/net)
Note: All wooden packaging materials must undergo proper fumigation treatment prior to use.

The following are some of the actual photos of the workshop


1. What is OPGW-3 fiber optic cable used for?
OPGW-3 is an optical ground wire designed for high-voltage power transmission lines, combining electrical grounding with fiber optic communication. It protects against lightning and supports real-time data transmission for grid monitoring.
2. What is the structure of the OPGW-3 cable?
It features a central stainless steel loose tube that houses optical fibers. The tube is surrounded by aluminum-clad steel wires, which provide tensile strength and conduct grounding current, ideal for aerial high-voltage environments.
3. What fiber types and core counts are supported?
OPGW-3 supports 12 to 144 cores with G.652D or G.655C single-mode fibers, commonly used in long-haul, backbone, and substation communication networks.
4. What are the benefits of stainless steel tube construction?
The central stainless steel tube provides:
5. Is the cable suitable for long-span installations?
Yes. OPGW-3 is designed to withstand long spans, high tension, and extreme environments, making it ideal for transmission towers and utility corridors over rough terrain.
