S13 transformers have introduced a most ideal core configuration, performance silicon steel strips, and advanced manufacturing processes and are manufactured via optimized design and elaborate processing. Now the product line has been qualified by strict testing made by a national authoritative test center and has attained a domestically leading level in quality and in performance.
In the structural and technical aspects, the iron core is not perforated and built with 45-degree mitered joints, with the limbs tied with semi-dry unidirectional weftless fiberglass adhesive tapes, having the characteristics of low height and low loss.
When storing the transformer, the oil level should be kept above the tank cover, and the storage conditions shall be regularly checked. For transformers transported with the conservator tank disassembled, the tank must be installed to keep certain oil pressure and oil volume, so as to adapt to temperature changes.
In order to reduce partial discharge and improve product reliability, the oil-filling process under vacuum, the vacuum requirement for oil filling, the evacuation time, and the oil filling speed are strictly controlled to ensure that the oil temperature is not lower than 60℃
