Typical Designs of Lightning Resistant Central
Stainless Steel Tube OPGW with Compressed Wires
The central stainless steel tube is surrounded by double layers of aluminium clad steel wires(ACS),the inner layer aluminium clad steel wires are compressed,the outer layer aluminium clad steel wires are all compressed or all round.
Compressing round AS wires into sector AS wires during stranding.
Compared with round AS wires stranding, sector AS wires stranding can increase the cross section and fault current capacity while the cable diameter is the same.
Compared with round AS wires stranding, sector AS wires stranding can dramatically increase the diameter of outer wires to enhance the lightning performance.
Apply to the transmission line which requires small diameter and large fault current.
Apply to heavy thunderstorm areas.
Fiber Count & Max Configuration:
Cables typically range from 16 to 48 fibers, depending on the model.
Cable Diameter:
Diameters range from 11.75 mm to 22.5 mm, with the smallest cables being those with 16 fibers (OPPC-70/10) and the largest having 48 fibers (OPPC-240/55).
Cable Weight (kg/km):
Cable weights vary significantly, from 281 kg/km (OPPC-70/10) to 1037 kg/km (OPPC-240/55). Heavier cables generally have more fibers and larger diameters, which correspond to higher strength and greater electrical capacity.
Tensile Strength (RTS in kN):
Ranges from 24.3 kN (OPPC-70/10) to 102.5 kN (OPPC-240/55). This indicates the maximum force the cable can withstand before breaking. Larger diameter cables tend to have higher tensile strength, making them more suitable for areas with higher mechanical stress.
Current Carrying Capacity (Amperage):
OPPC-70/10: 216-299 A (depending on temperature)
OPPC-110/25: 299-418 A
OPPC-150/25: 351-495 A
OPPC-185/25: 395-561 A
OPPC-230/40: 455-652 A
OPPC-240/55: 467-672 A
Varies based on the cable size and fiber count:
Current carrying capacity increases with the cable size and the number of fibers. The amperage varies slightly based on the temperature (40-70°C, 40-80°C, 40-90°C), with higher temperatures generally resulting in a decrease in current capacity.
Smaller cables (e.g., OPPC-70/10): Lower fiber count, smaller diameter, lighter weight, and lower tensile strength, but suitable for lower current applications.
Larger cables (e.g., OPPC-240/55): Higher fiber count, larger diameter, heavier weight, and significantly higher tensile strength and current carrying capacity, making them ideal for areas requiring more power transmission and mechanical durability.
1.Cable Sheath Marking
Unless otherwise specified, the cable sheath marking shall be as follows:
Color：White
Contents：ZION, the year of manufacture, the type of cable, cable number, length marking Interval: 1±0.2% m
Outer sheath marking legend can be changed according to user's requests.
2.Reel Length
Standard reel length: 2/3 km/reel, other length is also available.
3.Cable Drum
The cables are packed in fumigated wooden drums or plywood drums.
4.Cable Packing
Both ends of the cable will be sealed with suitable plastic caps to prevent the entry of moisture during shipping, handling and storage. The inner end is available for testing.
