Hollow Conductors

No one could offer as wide a variety of Hollow conductor tool forms than Luvata.

Luvata’s hollow conductors come in a wide range of sizes. They start from 4 x 4 mm (< 0.1 kg/m) and continue up to above 100mm in width (>20 kg/m). They can be produced in a variety of shapes.

Process

The finished product is obtained by drawing the conductor through a die, which is specific for each section and which always uses a mandrel in the bore. This method ensures fine tolerances and a smooth surface finish both in the bore and on the outside. Eddy Current is one of our tests used and supplementary tests are available upon request.

Material for Hollow conductors

Our hollow 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 brazeability and weldability, making them superior to oxygen-bearing copper grades.

Copper hollow conductors are most commonly used in electric motors and generators in the power generation industry.

Delivery forms

• straight lengths
• loose coils
• pancake coils
• spools

Long continuous lengths result in a reduced number of joints and have the benefits of lower costs and reduced risk of leakage.

Packaging

• wooden boxes
• bundles
• coils
• spools
• reels
