Material Selection and Procurement
Due to our rich experience in production and manufacturing for power transformer, we have a wealth of selection advantages and price advantages in the selection of raw materials and suppliers. The quality and price of the products are advantages for us.
  • Core Material: Grain-oriented electrical steel is typically selected for the transformer core due to its high magnetic permeability.
  • Copper/Aluminum Windings: High-conductivity copper or aluminum is chosen for the windings.
  • Insulation Materials: Insulating paper, pressboard, and varnishes are selected based on their dielectric properties.
  • Tank and Enclosure: The materials for the tank and enclosure (usually steel) are selected for durability and corrosion resistance
Core Construction
In order to assure the implementation ofthe advance design and manufactural tech-nology,some key equipments,moulds andtools had been repleced,moulds andimprovedwith the new technologies to meetthe requrements of product quality.
  • Core Cutting: The steel sheets are cut into specific shapes and sizes according to the design.
  • Core Assembly: These sheets are stacked together to form the transformer core, usually in a step-lap formation to minimize losses.
