Electrical transformers; liquid dielectric, having a power handling capacity not exceeding 650kVA

HS v2017 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 power distribution systems, enabling the efficient transmission of electricity from generation sources to end-users. As a key component of the electrical infrastructure, this industry is essential for supporting economic growth and development across various sectors.

Production process

The production of electrical transformers with liquid dielectric involves several key steps. First, the core of the transformer is constructed using high-quality steel laminations, which are stacked and assembled to create the magnetic circuit. The windings, made of copper or aluminum, are then carefully wound around the core. The transformer is then sealed and filled with a dielectric liquid, typically mineral oil or a synthetic fluid, which helps to insulate the windings and dissipate heat. Finally, the transformer is tested for performance and safety before being packaged and shipped to customers.

Production inputs

The main inputs required for the production of hs code 850421 transformers include high-grade steel for the core, copper or aluminum for the windings, and dielectric liquids such as mineral oil or synthetic fluids. Additionally, specialized machinery and equipment, such as winding machines, core stacking tools, and testing equipment, are essential for the manufacturing process. Skilled labor, including electrical engineers and technicians, is also a critical input for this industry.

Production outputs

Electrical transformers with liquid dielectric, as described by hs code 850421, are primarily used in power distribution systems to step down or step up voltage levels. These transformers are often found in substations, power plants, and industrial facilities, where they play a vital role in ensuring the reliable and efficient transmission of electricity. The outputs of this industry may be consumed by a wide range of other industries, including 271 Electricity, gas, steam and air conditioning supply, 281 Manufacture of machinery and equipment n.e.c., and 351 Electric power generation, transmission and distribution.
