Product Description

Cold-Rolled Silicon Steel Sheets: 12kV CT 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 has excellent dielectric properties and mechanical strength, is the first choice of 12kV CT insulation material. Epoxy castings provide reliable insulation that protects internal components from electrical breakdown and environmental factors..


Copper : Copper conductors are typically used for windings in 12kV CT. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.


Material (Epoxy Resin ): 12kV CT 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.
