HS v2022 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 electricity transmission and distribution infrastructure, enabling the efficient and reliable transfer of power across long distances. They are essential components in various industrial, commercial, and residential applications, contributing to the overall functioning of the broader economy.

Production process

The production of electrical transformers under HS code 850422 typically involves a multi-step process. First, the core of the transformer is constructed using high-grade electrical steel laminations, which are stacked and assembled. The windings, 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 enclosed in a tank filled with a liquid dielectric, such as mineral oil or synthetic fluid, which helps cool the unit and insulate the internal components. Finally, the transformer undergoes rigorous testing and quality control measures before being shipped to customers.

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 stacking tools, and testing apparatus, are essential for the manufacturing process. Skilled labor, including electrical engineers and technicians, is also a critical 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 a wide range of applications, including power transmission and distribution networks, industrial facilities, and large commercial buildings. The output of this industry may be consumed by other industries, such as 853610 Electrical apparatus for switching or protecting electrical circuits, 853620 Automatic circuit breakers, and 853630 Other apparatus for protecting electrical circuits.
