Overhead Bare Electric Cable ACSR Steel Reinforced Aluminum AAC Conductor

Product Description

Product Overview

Bare conductor is a type of metal conductive wire without any insulating sheath, mainly manufactured from copper, aluminum and steel-aluminum composite materials such as ACSR, AAC and AAAC. Benefiting from the insulation-free structure, it boasts excellent heat dissipation, stable electrical conductivity, low cost and convenient daily inspection. Our bare conductors strictly comply with IEC, GB and ASTM international standards, with reliable tensile and anti-fatigue performance. They are extensively used in overhead power transmission lines, substation busbars, lightning protection grounding systems and high-current industrial equipment connections, being an economical and reliable conductive material for power grid construction and industrial power supply projects.

Scenario Coverage

Bare conductors are extensively used in overhead transmission and distribution lines of power grids, busbar systems in power stations and substations, lightning protection and equipment grounding networks, high-current connecting components for metallurgy and electrolysis industries, temporary overhead power lines on construction sites and internal conductive parts of heavy-duty bus ducts, perfectly fitting outdoor power delivery projects and large-load industrial power connection demands.
