HS v2017 Code: 850434

About transformers; n.e.c. in item no. 8504.2, having a power handling capacity exceeding 500kva

hs code 850434 covers transformers with a power handling capacity exceeding 500kVA, which are essential components in high-voltage electrical transmission and distribution systems. These transformers play a crucial role in the efficient and reliable delivery of electricity, enabling the transfer of power from generation sources to end-users across the power grid. As a key infrastructure asset, transformers in this HS code category are vital to the functioning of modern economies and the development of industrial, commercial, and residential sectors.

Production process

The production of transformers covered under hs code 850434 typically involves a multi-step process. It begins with the manufacturing of the core, which is made from high-quality electrical steel laminations. The windings, which are composed of copper or aluminum conductors, are then carefully wound around the core. The windings are insulated to prevent short circuits and ensure safe operation. The assembled core and windings are then placed in a tank filled with insulating oil, which helps to cool the transformer and provide additional insulation. Finally, the transformer is fitted with accessories such as bushings, tap changers, and monitoring devices to ensure optimal performance and safety.

Production inputs

The main inputs required for the production of transformers under hs code 850434 include high-grade electrical steel for the core, copper or aluminum for the windings, insulating oil, and various electrical and mechanical components such as bushings, tap changers, and monitoring devices. Specialized machinery and equipment, such as winding machines, core cutting and stacking machines, and oil filling and testing equipment, are also essential inputs for the manufacturing process.

Production outputs

Transformers produced under hs code 850434 are primarily used in high-voltage electrical transmission and distribution systems, where they are responsible for stepping up or stepping down voltage levels to ensure efficient and safe power transmission. These transformers are often used in substations, power plants, and industrial facilities. The output of this industry may be consumed by other 850421 Liquid dielectric transformers, 850422 Liquid dielectric transformers, having a power handling capacity exceeding 650kVA, and 850423 Liquid dielectric transformers, having a power handling capacity not exceeding 650kVA industries, as well as the broader 8504 (Electrical transformers, static converters (for example, rectifiers) and inductors) industry.
