Product Overview

This series of copper busbar annealing furnaces features a large-capacity, high-uniformity thermal field design, specifically developed for long or high-volume busbar heat treatment. Using a sealed stainless steel muffle tank combined with advanced high-vacuum systems and N₂/Ar/H₂ atmospheres, it ensures busbars remain under absolute protection during heating (up to 950°C) and cooling, eliminating oxidation issues like surface reddening or blackening.

Key Application Values

• Superior Softening: Precise control of the annealing process provides T2 copper busbars with ideal elongation and bending properties, preventing installation cracks.
• Conductivity Assurance: Zero-oxygen heat treatment avoids oxidation of internal impurities, ensuring high conductivity (IACS).
• Surface Consistency: Multi-zone independent temperature control ensures consistent color and hardness from end to end, even for multi-meter busbars.
• Cost Efficiency: Non-oxidation annealing eliminates the need for expensive pickling, achieving eco-friendly production and significantly lowering per-unit costs.
