Central Al-Covered Stainless Steel Tube OPGW Design | Enhanced Optical Ground Wire for Overhead Power Lines

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.

Characteristic and Application

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.

Typical Parameters

• Cable Type (OPPC-XX/YY): Various OPPC (Optical Phase Conductor) models.
• Current Rating (measured in Amps, likely the maximum current each cable can carry under different temperature ranges).
• Temperature Ranges: Different operating temperatures: 40-70°C, 40-80°C, and 40-90°C.
• Other Values: The remaining values are likely related to different specifications, such as power loss, tensile strength, or specific electrical characteristics at those temperatures.
