Single-phase Transformer Core

The single-phase transformer core is mainly used in residential distribution, industrial control equipment, and power supply devices. Its shape is usually a two-limb rectangular core-type structure. Two vertical limbs connect through upper and lower yokes to form a closed rectangular magnetic path. This simple and compact structure is suitable for single-phase voltage transformation. We produce these cores using genuine grain-oriented silicon steel coils from Baowu and Ansteel. The thickness options are 0.23mm, 0.27mm, or 0.30mm based on your requirements. Our single-phase transformer core is built for efficiency.

Our company has 26 years of experience in single-phase transformer core production. Single-phase transformers usually have smaller capacities than three-phase units. However, the dimensional precision requirements are equally strict. The window size of the rectangular core is especially important. It directly affects whether the coils can be assembled smoothly. Our shearing lines use CNC automation. They precisely control the dimensions of every silicon steel sheet. After lamination, we use special gauges to verify the window dimensions. This ensures that the coils fit without sticking or excessive gaps. Our single-phase transformer core is made with precision.

Focus on Joint Quality and Gap Control

Our quality inspection focuses on the joint quality between the limbs and yokes. The magnetic circuit of a single-phase transformer is relatively simple. Changes in magnetic resistance at the joints have a greater impact on overall performance. Therefore, we carefully control the overlap length and offset distance during lamination. This prevents through gaps. Our inspectors use feeler gauges to check the joint gaps on a sample basis. They record the measurement data. Each batch has complete inspection records for quality traceability. Our single-phase transformer core is built with attention to every joint.
