The 24-core opgw optical cable weighs one meter
The approximate weight of a 24-core OPGW cable is typically around 0.35–0.47 kg/m (0.24–0.32 lbs/ft), depending on design and materials.
Cable Construction and Weight Factors
A 24-core OPGW cable consists of a central stainless steel tube housing the optical fibers, surrounded by aluminum-clad steel (ACS) wires or a combination of ACS and aluminum alloy wires for mechanical strength and grounding purposes . The weight of the cable depends on:
- Number of fibers: 24 cores in this case.
- Metallic layers: Single or double layers of ACS or aluminum alloy wires.
- Overall diameter: Typically ranges from 11–13 mm for 24-core designs.
- Protective coatings: Stainless steel tube and aluminum sheath add to the total weight.
Typical Weight Range
Based on industry examples and similar OPGW designs:
- Weight per meter: Approximately 0.35–0.47 kg/m.
- Weight per foot: Approximately 0.24–0.32 lbs/ft.
- Reel weight: A standard 2–3 km reel of 24-core OPGW can weigh 700–1,400 kg, depending on the exact construction and length .
Applications
24-core OPGW cables are used for:
- High-voltage transmission lines (110 kV and above) as a ground wire.
- Data, voice, and video transmission along power lines.
- Monitoring systems such as lightning waveform detection, unmanned substation monitoring, and power line protection systems .
Notes
- Exact weight may vary by manufacturer and specific design; always refer to the manufacturer's datasheet for precise calculations.
- Installation planning should consider sag, tension, and mechanical load in addition to cable weight. This weight estimate provides a practical guideline for engineers and planners handling 24-core OPGW cables.
