Intro to Silicon Steel Current Transformer Core TRANSMART

Silicon steel CT CORES have good magnetic permeability, low cost, mature manufacturing processes, and are widely used in current transformers. Low magnetic saturation induction strength, and they have higher losses at high frequency.

Due to their high magnetic permeability and low cost, silicon steel CT CORES are suitable for mass-produced current transformer products. The thermal stability of silicon steel CT CORES is excellent, allowing them to withstand high temperatures, and their low coefficient of thermal expansion maintains stability in shape and size even at high temperatures. This makes silicon steel CT CORES suitable for use in many high-temperature environments, such as transformers, motors, and other applications where they are widely employed.

The shape of the silicon steel CT core can be rectangular or toroidal, with or without cutting, depending on the specific technical design and requirements.
