Three-dimensional Wound Core

The three-dimensional wound core has a triangular three-dimensional shape and comes in a closed state. Compared to traditional flat laminated cores, this structure offers better magnetic circuit symmetry and higher three-phase balance. It effectively reduces no-load loss and noise levels. This makes it popular for energy-saving distribution transformers. We use high-permeability grain-oriented silicon steel coils from Baowu and Ansteel. The continuous winding process creates a core without joints. The magnetic flux path is smooth and efficient. Our three-dimensional wound core delivers superior performance.

Our company has 26 years of core manufacturing experience. We have a deep understanding of wound core production. The main challenges in making a three-dimensional wound core are achieving symmetry in the triangular frame and maintaining uniform winding tension. Too much tension can damage the silicon steel coating. Too little tension leads to loose laminations. Our operators receive special training. They adjust the winding parameters based on the steel thickness and grade. We use high-precision testing equipment to measure roundness, flatness, and three-phase height differences. This ensures every product meets your expectations. Our three-dimensional wound core is the result of this precision.

Applications and Capacity Coverage

This core type is used in both dry-type and oil-immersed transformers. We offer full sequence coverage from SCB12 to SCB18 for dry types. We also cover S11 to S22 for oil-immersed types. The capacity ranges from 25kVA to 10000kVA. The voltage rating goes up to 110kV. The three-dimensional wound core is especially suitable for residential areas, commercial complexes, and hospitals. Its low noise levels and balanced magnetic circuit make it a great choice. Our three-dimensional wound core helps you meet strict noise regulations.

Flexible Production and Specialized Packaging

Our production schedule is flexible. Our monthly capacity is 1,200 tons. We can handle large-volume orders from our clients. From order confirmation to delivery, we keep you informed. For urgent projects, we can prioritize production to shorten the waiting time as much as possible. For packaging, the triangular shape needs special care. We use custom-made wooden pallets and anti-collision corner guards. This protects the product from compression and deformation during storage and transport. Our three-dimensional wound core arrives in excellent condition.
