Applications of Horizontal Winding Machine
The horizontal winding machine is a classic piece of equipment for transformer coil manufacturing, suitable for most standard power transformers. Its characteristic is that the coil rotates on a horizontal axis, allowing operators to observe and operate from ground level or a platform. 2026-03-31
Vertical Winding Machine — Pit Type vs. Floor Type Comparison
For large power transformers or special coils (e.g., railway locomotive coils), vertical winding machines are superior to horizontal ones. They use gravity to counteract centrifugal force, solving the problem of radial loosening in large coils. 2026-03-31
Detailed Technical Analysis of Expanding Mandrel Series
The expanding mandrel is the core tooling that ensures tightness between coil turns and roundness. It solves the industry pain point of the mandrel "getting stuck" and being impossible to remove after winding 2026-03-31
