Product Description

Cold-rolled silicon steel sheet :Because of its excellent magnetic properties, it is widely used as the core material of 33kV current transformer in electric power industry. Cold rolled silicon steel sheet has the characteristics of high permeability and low core loss, which makes it excellent in energy transmission. They are able to efficiently conduct magnetic fields, convert electrical energy into magnetic energy, and transmit it to other electrical devices.


Epoxy resin: Epoxy resin is a widely used material with excellent dielectric properties and mechanical strength. Especially suitable as 33kV current transformer primary insulation material. The dielectric properties of epoxy resins refer to their ability to resist the flow of current, which is essential to ensure the safe and efficient operation of electrical equipment. Due to its high dielectric strength, epoxy resins can withstand high voltage levels without breaking down, making them ideal for current transformer insulation.


In addition to its dielectric properties, epoxy resin also offers exceptional mechanical strength. It has a high tensile strength, which means it can withstand significant mechanical stress without deforming or breaking. This makes it highly reliable in protecting internal components of current transformers from external forces and vibrations.


Epoxy castings are made by pouring epoxy resin into a mold to provide reliable insulation for current transformers. The casting process ensures a uniform and seamless insulation layer that effectively prevents electrical breakdown and leakage. In addition, insulation blocks moisture, dust, chemicals and other environmental factors, further enhancing the protection of internal components. This manufacturing method ensures the quality and reliability of the castings, making it one of the commonly used insulation materials in the power industry.


Copper : Copper conductors are typically used for windings in 33kV current transformers. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.
