One of Chinese manufacturer of Custom Current Transformer, offering excellent quality at a competitive price, is Dahu Electric. Feel free to get in touch.
Cold-Rolled Silicon Steel Sheets: Custom current 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 Custom current 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 Custom current transformer. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.
Material (Epoxy Resin ): Custom 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.
DAHU Electric’s Custom current transformer is a crucial device in indoor switch gear. It offers a powerful solution for current measurement, electrical energy monitoring, and protective relays in both single-phase and three-phase AC systems. It operates smoothly at 50Hz or 60Hz and can handle equipment voltages up to 12kV. The design and functionality of the Custom current transformer make it an essential component of the power system. It accurately measures current, monitors energy consumption, and provides protection in case of power system failure. With the Custom current transformer, users can monitor the power system’s real-time operation and take necessary actions promptly to ensure its safe and stable operation.
Our product plating of screws and bottom plate reaches 8um/min, which is more moisture-proof and rust-proof. The gloss is better.
