Product Description

S13series oil-immersed power transformer

1. HV winding is made with polyvinyl acetal wire enamel wire, layer type, double-sided glue dots paper are used as the layer insulation between layers, it will stick together after dry, so that the HV winding to solidify to a solid after dry. HV winding ampere-turns arranged by our specific technology, it will reduce axial strength during short circuit happen.
2 Corrugated tank structure used in the transformer design. The imported corrugated tank production line can produce the corrugated sheet and welding seam automatically, the weld the tank rim and bottom on the welding desk, it will be performed the leakage test after welding process finished one tank by one tank, and a finally leakage test for whole transformer to ensure the quality of sealing.
3. The oil will be filling in the transformer under vacuum condition, strictly and advanced technology greatly improved the insulation strength of transformer.
4. Lastest invention technology are used on designing of transformer bushing, no pressure pin and plate on the outside, it avoids oil leakage, steel rust and etc, the structure is reasonable and contour artistic.
5. Oil level gauge with magnetic plate structure, it can fully isolation the oil tank and air, can ensure the quality of transformer oil not to effect by ultraviolet radiation.
6. Bar-type No Circuit Tap Changer used on the transformer design, it is easy to be operated. It can be automatically and quickly switched, and have obviously feeling during switched by hand. Effectively solve the problems of switch as other tap-changer. Client can also add a lock to prevent the non-normal random switching according their requirement.
