Overview

This iron core oil immersed transformer series consists of three-phase distribution transformers with 3D wound cores for high efficiency operation. Compared with series S9, 80% of no-load currents and 30-40% of no-load loss can be decreased. Theses power distribution components are applicable for the power supply and lighting systems of agricultural, mineral, petrochemical and other industrial fields.

Product Features

Product Item	Three-dimensional volume iron core oil-immersed transformer	Folding iron core oil-immersed transformer
Material Saving	Waste-free processing, that is when suit cutting, material utilizing rate is 100% and can save the silicon steel sheet using quantity by 25~30% and copper using quantity by 5~8%.	Material utilizing rate of silicon steel sheet is not high and waste materials are higher.
Loss and no-load current	Three-dimensional volume iron core three-phase magnetic circuit without seam, magnetic flux direction is completely consistent with silicon steel sheet crystal orientation, substantially reduce no-load loss and no-load current.	There are a lot of air gaps formed by seams in magnetic circuit, this kind of air gaps increase the reluctance of magnetic circuit, and thus increase the losses and no-load current.
Balance of three phase	Three-dimensional volume iron core are formed by three same single frames. Three core limbs are arranged in stereo by an equilateral triangle, three magnetic circuits’ length is consistent and also the shortest, the loss of three core limbs is consistent and so the three phase is balanced.	Not balanced
Third harmonic	Reduced	Not reduced
Electromagnetic intensity	Low	High
Anti-short circuit ability	Strong	Common
Production efficiency	There are 5-6 process less than folding iron core, so production efficiency is higher and quality is more stable.	Low
Volume	A small covering area	Large
Guard against theft	The iron cores are not easily accessed without professional tools.	Resistance against theft is not high.
