Manufacturing Process
Composite conductors are primarily used in windings of oil-immersed transformers, reactors, and other electrical equipment, especially suitable for:
Large power transformer windings: Meets the requirements for long continuous winding, enhancing overall winding performance.
Reactor windings: Compact structure and neat arrangement, ideal for reactor designs requiring high inductance and low losses.
High-reliability electrical equipment: Suitable for applications with strict requirements for electrical insulation and mechanical strength.
Customized winding structures: Flexible arrangement and insulation material options based on electrical and structural needs.
High power density equipment: Ideal for winding designs with limited space but high current-carrying capacity requirements.
How to Choose Composite Conductors
Material Type
Copper vs aluminum – Copper is preferred for high conductivity, while aluminum offers a lightweight and cost-effective alternative.
Insulation Thickness
Thicker insulation can handle higher voltages but may reduce flexibility.
Temperature Rating
Ensure the wire can withstand the maximum operating temperature of your application.
Mechanical Properties
Evaluate the wire' s flexibility and tensile strength based on winding and installation needs.
