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

HS v2017 Code: 850423

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

hs code 850423 covers electrical transformers with liquid dielectric, designed to handle power 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. They are an integral component of modern electrical infrastructure, supporting the growth and development of industries, communities, and economies worldwide.

Production process

The production of 850423 transformers involves a multi-step process. First, the core is constructed using high-quality electrical steel laminations, which are stacked and secured. The windings, made of copper or aluminum, are then carefully wound around the core. The windings are insulated to prevent short circuits. The transformer tank is then filled with a specialized insulating liquid, typically mineral oil or a synthetic alternative, which helps dissipate heat and provides additional insulation. Finally, the transformer is tested for performance, safety, and compliance with industry standards before being delivered to the customer.

Production inputs

The production of 850423 transformers requires several key inputs. High-grade electrical steel is needed for the core, while copper or aluminum is used for the windings. Specialized insulating liquids, such as mineral oil or synthetic alternatives, are essential for cooling and insulation. Additionally, the manufacturing process requires advanced machinery and equipment, including winding machines, core stacking tools, and testing equipment to ensure the transformers meet rigorous quality and safety standards.

Production outputs

850423 transformers are primarily used in high-voltage electrical transmission and distribution systems. They are often found in substations, power plants, and industrial facilities, where they step down the voltage to levels suitable for commercial and residential use. The output of these transformers is consumed by a wide range of 850421 Electrical transformers; liquid dielectric, having a power handling capacity not exceeding 650kVA, 850422 Electrical transformers; liquid dielectric, having a power handling capacity exceeding 650kVA but not exceeding 10,000kVA, and 853710 Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or the distribution of electricity.
