COPPER CONDUCTOR TECHNICAL SPECIFICATION

SOLID COPPER CONDUCTOR (CIRCULAR) – CLASS 1

A solid copper conductor consists of a single, circular strand designed for high performance in electrical applications. It offers superior mechanical strength and stable conductivity, making it ideal for use in transformers and other electrical equipment. With a minimum conductivity of 101% IACS, it ensures efficient and reliable current flow in demanding environments.

RIGID STRANDED CONDUCTORS – CLASS 2

Rigid Stranded (Class 2) are made of multiple strands of high-purity copper, providing moderate flexibility while maintaining excellent mechanical strength. Designed primarily for fixed installations, they offer reliable 101% IACS conductivity and are easier to handle than solid conductors in larger cross-sections.
