Product Introduction:

This product has the performance of low no-load loss, low no-load current and low noise, and the power saving effect is remarkable. It improves the voltage quality and the reliability of power supply, and is a green energy-saving equipment that is conducive to environmental protection, and is the latest product for the promotion and use of urban and rural power grid technology transformation projects. The S13-M.RL and S11-M.RL series fully sealed three-phase coiled core transformers produced by the company are different from the traditional planar laminated core transformers. Sales Hotline: 13508930968

Its core is composed of a three-phase column yoke arranged in a three-dimensional triangle with a single frame piece. Each cylinder is continuously rolled from high-quality cold-rolled silicon steel strip, and the width is cut in a straight or curved line by a CNC cutting machine. The strip is wound on the core winder to form a near-circular or folded arc frame, and then it is annealed by vacuum nitrogen filling to eliminate the processing stress, reorient the lattice, increase the magnetic permeability, and improve the electromagnetic performance; The high and low voltage coil uses a special winding machine, which is directly wound on the paper tube of the iron core column, the overall structure is solid and compact, the body is insulated and laminated with upper and lower iron yokes, and the screw is pulled around to tighten the coil to make it stable and reliable, and can withstand the impact of sudden short circuit.
