Import Central Stainless Steel Tube Opgw — Buy in wholesale FOB from Supplier in China

The Central Stainless Steel Tube OPGW (Optical Ground Wire) integrates optical fibers within a stainless steel tube, surrounded by single or double layers of aluminum-clad steel wires or a mix of aluminum-clad steel and aluminum alloy wires. This design provides superior protection for the optical fibers against moisture, lightning, and extreme environmental conditions, making it ideal for high-voltage power transmission lines. The stainless steel tube ensures long-term reliability, while the outer layers offer mechanical strength and electrical conductivity.

OPGW cables are engineered to meet rigorous standards, including ITU-T G.652 for single-mode optical fibers and IEC 60794-4-10 for aerial optical cables along electrical power lines. Typical designs include single-layer and double-layer configurations, with fiber counts ranging from 12 to 60 and diameters from 7.8 mm to 18 mm. Standard weights for these cables vary between 243 kg/km to 910 kg/km, depending on the fiber count and structural design. The rated tensile strength (RTS) and short-circuit capacity are critical performance parameters, with typical RTS values ranging from 40.6 kN to 141 kN and short-circuit capacities from 4.7 kA²s to 132.2 kA²s.

These cables are primarily used in the construction and upgrade of high-voltage power lines, particularly those operating above 110 kV, where reliability and durability are paramount. Buyers include power utility companies, electrical infrastructure contractors, and telecom providers seeking to deploy fiber-optic networks alongside power transmission systems. Trade terms often involve bulk orders with customizable specifications, and buyers should confirm compatibility with their existing power line infrastructure and environmental conditions.
