Conductive Components for Nuclear Power

Yantai Wanlong Vacuum Metallurgy Co., Ltd. is one of the most reliable manufacturers and suppliers of conductive components for nuclear power in China. With abundant experience, we are committed to providing high quality customized products for global clients. Welcome to buy bulk premium conductive components for nuclear power from our factory.

This module covers the high-purity copper and copper-alloy conductive components for 1000MW nuclear power generator units, including conducting rods, conductive joints and Havel fittings. All products are manufactured via forging, heat treatment and precision CNC machining, featuring dense internal micro structure, tight dimensional tolerance and stable positioning. They serve as the core current-carrying and mechanical-connection parts inside large generators, reliably transmitting heavy current, bearing combined electrical and mechanical loads, and maintaining stable performance under high-current, thermal stress, clamping force and vibration conditions.

Outstanding electrical and thermal conductivity with low resistivity; sufficient mechanical strength, good thermal-fatigue resistance and low contact resistance. The material maintains stable dimensional and mechanical properties under high-current and temperature-rise conditions, with good anti-fatigue and anti-creep performance suitable for long-term continuous operation. Strict non-destructive inspection is performed to comply with nuclear power quality control and inspection specifications.

Primarily used as the core conductive and connecting components for 1000MW nuclear power generator units, including rotor-end conducting rods, conductive joints and Havel fittings for connection and mechanical fastening. Also widely applied in large thermal power generators and other high-power electrical equipment for heavy-current transmission and conductive connection.

• Integral forging minimizes internal defects such as porosity and inclusions, greatly improving reliability under long-time high-speed rotating working conditions.
• Optimized heat treatment balances electrical conductivity, mechanical strength and creep resistance, ensuring stable performance under combined electrical and mechanical loads.
• Precision CNC machining achieves tight dimensional tolerance and excellent surface finish, ensuring seamless matching with rotor-end fittings and end rings during assembly.
• Low contact resistance and reliable connection effectively reduce contact heating and avoid local overheating under large current conditions.
• Good anti-fatigue, anti-creep and anti-corrosion performance, suitable for high-temperature, high-humidity, radiation and vibration environments.
• Full traceability covering raw material inspection, forging records, heat treatment reports and non-destructive testing (NDT), fully meeting nuclear industry traceability requirements.
• Custom size, structure, contact form and surface treatment available according to customer drawings and generator operating parameters.
