The upper and lower iron yokes are made of insulating cardboard; the balance pad is made of laminated wood for insulation; the lead bracket is made of laminated paper; all the fasteners are effectively locked lock nuts.

The strip is wound on a core winding machine to form a nearly circular or folded circular arc frame, and then vacuum-annealed to eliminate processing stress, reorient the lattice, improve magnetic permeability, and improve electromagnetic performance; special for high and low voltage coils.

The S13-M.RL The winding machine is directly wound on the iron core paper tube. The overall structure is solid and compact. The body adopts upper and lower iron yoke insulation and laminated wood. The screw is tightened around the coil to make it stable and reliable. It can withstand sudden short-circuits. impact.

The S13-M.RL series fully sealed three-phase three-phase wound core transformer is different from the traditional planar laminated core transformer. The iron core is composed of a three-phase cylindrical yoke with a three-dimensional triangular arrangement of a single frame piece.
