Description
Product Description
Cold-Rolled Silicon Steel Sheets: Because of its excellent magnetic properties, cold-rolled silicon steel sheet is often used as the core material of toroidal current transformer. These materials have high permeability and low core loss, making them efficient for energy transfer. They have lower hysteresis loops and magnetization losses compared to alternatives, resulting in less energy waste and lower power consumption.
Epoxy resin: Epoxy resin has excellent dielectric properties and mechanical strength, is the first choice of toroidal transformer insulation material. Epoxy castings provide reliable insulation that protects internal components from electrical breakdown and environmental factors.
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.
Copper : Copper conductors are typically used for windings in toroidal current transformer. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.
Material (Epoxy Resin ): Toroidal current transformer use enclosures made of epoxy resin, which has excellent insulation properties and can prevent current or voltage crossing for safe circuit operation. It is also resistant to high temperatures and corrosion, and has good sealing performance for waterproof and moisture-proof capabilities. Epoxy transformers are lighter and easier to install and maintain compared to oil-immersed transformers.
