Oxygen free copper grades are widely used for copper conductors because the minimized impurities will have the least impact upon the electrical conductivity performance, and our custom hollow conductors have electrical conductivity (IACS %) between 100% and 102%. Our oxygen free copper conductors are immune to hydrogen embrittlement and ensures safe joining with all brazing and welding methods. Our tight production control means we can control the whole manufacturing process from casting to signing the inspection certification and ensure the consistency of our product from batch to batch. Fabmann has been working with famous copper material manufacturers to produce top-notch hollow conductors, square & rectangular copper and copper alloy tubes, solid square or rectangular copper bar for the most demanding applications.

Insulation Service
Fabmann can provide insulation service for you , and our standard insulation material for hollow conductor is polyester imide + glass fiber which can easily reach working temperature 200°C with minimum voltage breakthrough over 5, 000V. Custom copper conductors with Insulation is essential for the safe and reliable operation of magnets, and it helps to prevent electrical breakdown, improve heat dissipation, protect against environmental factors, enhance mechanical strength, and reduce corona discharge. Without proper insulation, hollow conductors would be susceptible to a variety of problems that could lead to power outages, equipment damage, and safety hazards. Fabmann can help you to choose the most economic way of insulation, and the following insulations are the popular ones for hollow conductor insulation:
Insulation for Hollow Conductor
√ Sintered Polyester Imide Film
√ Polyester Imide Film with Enamel
√ Polyester Imide Film with Enamel + Glass Fiber
√ Polyester Imide Film with Enamel + Industrial Non-woven Fabric
All of these insulation materials can give very good insulation performance, in particular, polyester Imide with glass fiber can achieve highest thermal class 240.
