Description
Product Description
Cold-Rolled Silicon Steel Sheets: 11kV CT 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 11kV 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 11kV CT. These materials offer high electrical conductivity and mechanical durability, enabling efficient transmission of current signals while withstanding operational stresses.
Material (Epoxy Resin ): 11kV 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.
Product Details
The 11kV CT produced by CHENGHE Electric is a device that plays a key role in indoor switchgear, providing a powerful solution for current measurement, electrical energy monitoring and protective relays in single-phase and three-phase AC systems. These systems operate seamlessly at 50Hz or 60Hz, meeting a wide range of electrical requirements for equipment voltages up to 12kV. The design and functionality of the 11kV CT make it an integral part of the power system. It is able to accurately measure current, monitor electrical energy consumption, and provide protection in case of failure in the power system. By using 11kV CT, users can monitor the operating status of the power system in real time and take necessary measures in time to ensure the safe and stable operation of the system.
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.
