Aluminum foil for transformer windings is an important conductive material in the field of power transmission and electrical equipment, developed specifically to enhance the operational efficiency and structural stability of transformers. This product uses high-purity aluminum as the base material, possessing both excellent electrical and thermal conductivity, as well as outstanding mechanical plasticity and processing adaptability.
Aluminum Foil For Transformer Features
Low cost: Aluminum is cheaper than copper and weighs only 1/3 of copper, which can significantly reduce the overall cost of transformers and the difficulty of transportation.
Thermal stability: Adopting a foil winding structure, it has a large heat dissipation area and uniform heat distribution, which can effectively suppress the generation of hot spots. Even though aluminum has lower thermal conductivity than copper, it can still meet the thermal stability requirements of some equipment.
Process adaptability: It facilitates automated winding. Foil coil winding machines can achieve high-precision and high-efficiency production, adapting to the needs of large-scale manufacturing.
Applications
Transformers: The material cost of aluminum foil is far lower than that of copper foil, which can significantly reduce the manufacturing cost of transformers and meets the core demand for economy in medium and small capacity transformers. Its density is only 1/3 that of copper, and its lightweight property greatly reduces the weight of equipment, adapting to the requirements for convenience in installation and transportation of dry-type transformers, new energy transformers, and other such equipment.
