Electrical transformers; liquid dielectric, having a power handling capacity not exceeding 650kVA
HS v2022 Code: 850421
About electrical transformers; liquid dielectric, having a power handling capacity not exceeding 650kva
HS code 850421 covers electrical transformers with liquid dielectric, having a power handling capacity not exceeding 650kVA. These transformers play a crucial role in the power distribution infrastructure, enabling the efficient transmission and transformation of electrical energy across various industries and residential applications. As a key component in electrical systems, the 850421 transformers are essential for maintaining a stable and reliable power supply, supporting economic growth and development.
Production process
The production of 850421 transformers involves several key steps. First, the core of the transformer is constructed using high-quality electrical steel laminations, which are stacked and assembled to create the magnetic circuit. The windings, typically made of copper or aluminum, are then carefully wound around the core. The windings are insulated to prevent short circuits and ensure safe operation. The transformer is then sealed in a tank filled with a dielectric liquid, such as mineral oil or synthetic fluid, which helps to cool the unit and provide insulation. Finally, the transformer is tested for performance, safety, and compliance with industry standards before being shipped to customers.
Production inputs
The main inputs required for the production of 850421 transformers include electrical steel for the core, copper or aluminum for the windings, and dielectric liquids such as mineral oil or synthetic fluids for cooling and insulation. Additionally, specialized machinery and equipment, such as winding machines, core stacking tools, and testing equipment, are essential for the manufacturing process. Skilled technicians and engineers are also required to ensure the proper design, assembly, and quality control of these transformers.
Production outputs
The primary output of the 850421 transformer industry is, of course, the liquid-filled transformers themselves. These transformers are widely used in power distribution systems, substations, and industrial applications. The output of this industry may be consumed by other industries that require power transformation, such as 853610 Electrical apparatus for switching or protecting electrical circuits, 853620 Boards, panels, consoles, desks, cabinets and other bases for electric control or the distribution of electricity, and 853630 Electrical signaling, safety or traffic control equipment for railways, tramways, roads, inland waterways, parking facilities, port installations or airfields.
