Import Bare Conductor Opgw — Buy in wholesale FOB from Supplier in China

OPGW (Optical Ground Wire) bare conductor cable integrates a central stainless steel tube containing optical fibres with concentric layers of aluminium-clad steel (ACS) and/or aluminium alloy wires, providing simultaneous earth conductor and fibre-optic communication functions for high-voltage overhead transmission lines. Hangzhou Easy Electric Supply Cable Limited manufactures five construction variants: central tube with single or double armour; stranded single or multitube with double or three armour layers; central Al-covered stainless steel tube; aluminium tube; and central type aluminium tube, each with ACS-only or mixed ACS/aluminium alloy wire configurations. The source description specifies single, double, and triple armour layer options across these architectures, with no stated fibre count, tube diameter, or wire gauge data for this listing.

The central stainless steel tube, typically 1.0-2.0 mm wall thickness (standard for OPGW), houses single-mode or multimode optical fibres with gel filling for moisture and vibration protection. Aluminium-clad steel wires provide the tensile core and electrical conductivity, with aluminium alloy layers added to reduce weight and improve conductivity where mechanical load permits. Al-covered stainless steel tube variants enhance corrosion resistance in coastal or polluted environments. The aluminium tube variant offers improved thermal conductivity and lighter weight, though with reduced tensile strength compared to steel-tube counterparts. Typical ACS wire grades include 20.3% IACS conductivity (aluminium cladding over steel core), with aluminium alloy wires at 53% IACS (standard industry values).

Utilities and grid operators deploy OPGW on transmission towers at 110 kV and above, replacing traditional earth wires to add communication without additional right-of-way. Applications include SCADA, teleprotection, and broadband backhaul for rural electrification. Buyers should confirm fibre count, attenuation at 1310/1550 nm, short-circuit current rating (kA, 1s), and rated tensile strength (RTS in kN) directly with Hangzhou Easy Electric Supply Cable Limited, as these critical parameters are not stated in the source. Standard Incoterms and lead times require supplier confirmation.

Hangzhou Easy Electric Supply Cable Limited is located in Hangzhou, Zhejiang Province, China, with its address at Virgo Building, Wuchang Xixi Software Park. The supplier holds a Harbor trust tier on the platform. The response rate is recorded at 0.00 percent with an average response time of 0 hours, indicating no response history is available through the platform's messaging system. The listing provides no information about factory size, year of establishment, annual output, workforce numbers, or export markets served.

The company offers five distinct OPGW construction architectures, suggesting specialisation in optical-fibre composite overhead earth conductors rather than general cable manufacturing. No certifications (IEC, IEEE, or fibre-specific), test reports, or client references are listed. Buyers should verify ISO 9001 quality management status, IEC 60794-4-10 or IEEE 1138 compliance for OPGW, and factory inspection protocols before committing to volume orders. The product range appears technically focused, with no evidence of downstream installation or engineering services.
