Product Description

Cold-Rolled Silicon Steel Sheets: 10kV voltage transformer usually uses cold-rolled silicon steel sheets as its core. These materials are cold-rolled and have excellent magnetic properties, such as high permeability and low core loss, which makes them ideal for current transformers. By using cold rolled silicon steel sheet as the core material, the current transformer can achieve efficient energy transfer, thereby improving the efficiency of the system. Compared to other materials, cold-rolled silicon steel sheets have lower hysteresis loops and magnetization losses, which means less energy waste and lower power consumption.

Epoxy resin: Epoxy resin has excellent dielectric properties and mechanical strength, is the first choice of 10kV voltage transformer 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 10kV voltage transformer. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.

Material (Epoxy Resin ): 10kV voltage transformer 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.

Product Superiority

Our product plating of screws and bottom plate reaches 8um/min, which is more moisture-proof and rust-proof. The gloss is better.
