Electrical transformers; liquid dielectric, having a power handling capacity exceeding 10,000kVA

HS v2022 Code: 850423

About electrical transformers; liquid dielectric, having a power handling capacity exceeding 10,000kva

HS code 850423 covers electrical transformers with liquid dielectric, having a power handling capacity exceeding 10,000kVA. These transformers play a crucial role in the transmission and distribution of electricity, enabling the efficient and reliable transfer of power across vast distances. As a key component of the electrical infrastructure, this industry is essential for supporting the broader economy and powering various sectors, from manufacturing and commercial operations to residential communities.

Production process

The production of electrical transformers with liquid dielectric involves several specialized techniques. The core of the transformer is typically made from high-quality electrical steel, which is carefully cut, stacked, and assembled. The windings, which are responsible for the transformation of voltage, are then carefully wound around the core using copper or aluminum conductors. The transformer is then sealed and filled with a specialized insulating liquid, such as mineral oil or synthetic ester, to ensure efficient heat dissipation and insulation. Finally, the transformer undergoes rigorous testing and quality control measures to ensure its performance and safety.

Production inputs

The production of HS code 850423 transformers requires a range of specialized inputs, including high-grade electrical steel, copper or aluminum conductors, insulating liquids, and various other components such as bushings, tap changers, and cooling systems. Additionally, the manufacturing process relies on specialized machinery and equipment, as well as skilled labor to ensure the precise assembly and testing of these transformers.

Production outputs

Electrical transformers with liquid dielectric and a power handling capacity exceeding 10,000kVA, as described by HS code 850423, are primarily used in the transmission and distribution of electricity across high-voltage power grids. These transformers are essential for stepping down the voltage from the high-voltage transmission lines to the lower voltages required for distribution and end-use consumption. The output of this industry is consumed by a wide range of industries, including 271 Electricity, gas, steam and air conditioning supply, 351 Manufacture of electric motors, generators, transformers and electricity distribution and control apparatus, and 421 Construction of utility projects.
