Hollow Copper Conductors are available in a variety of cross-sections from complex to standard profile shapes. As with all our existing products Hollow Copper Conductor is available material and various other copper alloys. Our Hollow Copper Conductors are made from high-conductivity, oxygen-free copper OF-OK®, which is a high purity copper with an electrical conductivity of at least 100% IACS. If higher softening temperatures or creep strengths are required, we recommend the use of silver bearing copper grades CuAg 0.03% or CuAg 0.1%, which are based on OF-OK copper.
These copper grades offer high electrical and thermal conductivity and their freedom from oxygen ensures excellent braze-ability and weld-ability, making them superior to oxygen-bearing copper grades.
The conductor sections are manufactured by melting and drawing processes. The same are available in oval holes, quarrel holes, round hole and as per customer’s specific requests.
