Bare conductors are the backbone of overhead transmission and distribution systems, ensuring efficient and reliable electricity flow across utilities, industrial grids, and infrastructure projects. Designed to carry high current with minimal losses, bare aluminum conductors are widely used by power utilities, EPC contractors, grid developers, and government power authorities across the world. As a global manufacturer of overhead conductors and power cables, HNBF Power delivers high-performance AAC, AAAC, ACSR, and other bare conductor solutions engineered to meet demanding operational environments and international standards.

What is a Bare Conductor?

A bare conductor is an uninsulated metallic cable used primarily for overhead transmission and distribution lines. Typically manufactured using aluminum or aluminum alloy strands, sometimes reinforced with steel for added tensile strength, bare conductors provide high conductivity, lightweight structure, excellent corrosion resistance, and long service life. They are ideal for long-span installations and harsh outdoor applications.

Types of Bare Conductors Commonly Used in Power Projects

AAC (All Aluminum Conductor)

Suitable for short-span urban areas and distribution lines where high conductivity is essential.

AAAC (All Aluminum Alloy Conductor)

Offers higher strength and corrosion resistance than AAC, making it suitable for coastal, industrial, and high-corrosion zones.

ACSR (Aluminum Conductor Steel Reinforced)

Manufactured with a steel core surrounded by aluminum strands, ACSR provides superior tensile strength for long-span overhead transmission lines and high-voltage networks.

HNBF Power manufactures all these bare conductors in compliance with IEC, ASTM, BS, and other international standards, ensuring consistent quality performance.
