HS v2017 Code: 850422

About electrical transformers; liquid dielectric, having a power handling capacity exceeding 650kva but not exceeding 10,000kva

hs code 850422 covers electrical transformers with liquid dielectric, having a power handling capacity exceeding 650kVA but not exceeding 10,000kVA. These transformers play a crucial role in the transmission and distribution of electrical power, enabling the efficient and reliable transfer of electricity across power grids. As a key component of the energy infrastructure, this industry is essential for supporting economic growth and development across various sectors.

Production process

The production of electrical transformers covered under hs code 850422 typically involves a multi-step process. First, the core of the transformer is constructed using high-quality electrical steel laminations, which are stacked and assembled. The windings, made of copper or aluminum conductors, are then 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 liquid dielectric, such as mineral oil or synthetic fluid, to provide cooling and insulation. Finally, the transformer undergoes rigorous testing and quality control measures to ensure its performance and safety.

Production inputs

The main inputs required for the production of electrical transformers under hs code 850422 include high-grade electrical steel for the core, copper or aluminum for the windings, and liquid dielectric materials such as mineral oil or synthetic fluids. Additionally, specialized machinery and equipment, such as winding machines, core assembly tools, and testing equipment, are essential for the manufacturing process. Skilled labor, including electrical engineers and technicians, is also a crucial input for this industry.

Production outputs

The primary output of the industry covered by hs code 850422 is electrical transformers with liquid dielectric, having a power handling capacity exceeding 650kVA but not exceeding 10,000kVA. These transformers are used in various applications, including power transmission and distribution, industrial facilities, and commercial buildings. The output of this industry may be consumed by other industries that require reliable and efficient power distribution, such as 271110 Electricity generation, transmission and distribution and 271120 Manufacture of electricity distribution and control apparatus.
