22kv Current Transformer

Cold-rolled silicon steel sheet :22kV current transformer often uses cold-rolled silicon steel sheet as its core due to its excellent magnetic properties. These materials exhibit high permeability and low core loss, making them ideal for efficient energy transfer. They have lower hysteresis loops and magnetization losses compared to other options, resulting in less energy waste and lower power consumption.

Epoxy resin: Epoxy resin is a versatile and widely used material in various industries due to its excellent dielectric properties and mechanical strength. It is particularly favored as the primary insulation material for 22kV current transformers.

The dielectric properties of epoxy resin refer to its ability to resist the flow of electric current. This property is crucial in ensuring the safe and efficient operation of electrical equipment. Epoxy resin’s high dielectric strength allows it to withstand high voltage levels without breaking down, making it an ideal choice for insulation in current transformers.

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, which are made by pouring epoxy resin into molds, provide reliable insulation for current transformers. The casting process ensures a uniform and seamless insulation layer, which effectively prevents electrical breakdown and leakage. This insulation layer also acts as a barrier against environmental factors such as moisture, dust, and chemicals, further enhancing the protection of internal components.

Copper : Copper conductors are typically used for windings in 22kV current transformers. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.
