Single-phase Folded-corner Core

The single-phase folded-corner core is mainly used in single-phase distribution transformers, dry-type transformers, and reactors. Its shape is usually a two-limb rectangular frame. The magnetic path consists of two vertical limbs and upper and lower yokes. The folded-corner process creates a right-angle transition at the corners through special cutting and lamination. This structure improves window space utilization. It also makes coil assembly and fixing easier. We use genuine grain-oriented silicon steel coils from Baowu and Ansteel. This ensures that the material orientation at the corners is fully utilized. Our single-phase folded-corner core is a quality product.

Our core products have been exported to many countries around the world. We have extensive experience in export packaging and logistics. For the regular shape of single-phase folded-corner cores, our packaging process is well-established. The inner layer uses rust-proof paper and VCI vapor rust-proof film. The middle layer uses foam cushioning material. The outer layer uses strong wooden crates or fumigated pallets. This three-layer protection effectively resists salt spray corrosion and stacking pressure during sea transport. Our single-phase folded-corner core arrives at your facility in like-new condition.

Precision Control at the Corners

Our shearing lines can precisely cut the special shaped sheets needed for folded corners. The laminations at the corners use a staggered overlap method. This prevents local saturation in the magnetic path at the corners. Our quality inspectors use feeler gauges and calipers to check the gap and flatness of each batch. We know that the corner quality directly affects the transformer's no-load current and core heating. Only by controlling every detail can we deliver a product that meets your expectations. Our single-phase folded-corner core is built with attention to detail.

Full Service from Pre-Sale to After-Sale

Before the sale, our technical team confirms the window dimensions and mounting hole positions with you. These details are important for efficient coil assembly and final assembly. During production, we provide regular updates on progress. For domestic clients, we can also provide on-site installation support after delivery. We believe that professional craftsmanship and thoughtful service together form the reason why clients choose us. We look forward to providing reliable core support for your single-phase transformer projects.
