Product Description

Cold-Rolled Silicon Steel Sheets: 10kV current transformers commonly utilize cold-rolled silicon steel sheets for their core. These materials possess excellent magnetic properties, such as high permeability and low core loss, ensuring efficient energy transfer and minimal power dissipation.

Epoxy Resin: Epoxy resin is a preferred insulating material for 10kV current transformers due to its superior dielectric properties and mechanical strength.Epoxy resin casting provides reliable insulation, protecting internal components from electrical breakdown and environmental factors.

Copper : Copper conductors are typically used for windings in 10kV current transformers. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.

Material (Epoxy Resin ): 10kV current transformers are housed in enclosures made of epoxy resin. Epoxy resin has excellent insulation properties, can effectively prevent current or voltage crossing, to ensure the safe operation of the circuit.It has high temperature resistance and can adapt to the working requirements in high temperature environment.

It has good corrosion resistance, can resist the erosion of some chemical substances, and extend the service life of the transformer.It has good sealing performance, so the epoxy transformer usually has good waterproof and moisture-proof performance and is suitable for use in humid environments.Compared to traditional oil-immersed transformers, epoxy transformers generally have a lighter weight and are easy to install and maintain.
