Product introduction

This product implements the national standard GB1094 "Power Transformer" and GB/T6451 "Three-phase oil-immersed power transformer technical parameters and requirements."
The S11 series is a three-phase oil-immersed distribution transformer. The core material is selected from DQ133-30 (type 9),30QG120 (type 11), 23RK090 (type 13), 23RK080 (type 14)and other cold -rolled silicon steel sheets. The core material used in actual production is not lower than the pattern requirements.
The product adopts a fully sealed corrugated oil tank structure. The transformer oil and the surrounding air do not contact, so the transformer oil will not absorb the external moisture, and thus will not reduce the insulation strength, in addition, oxygen can not enter the fuel tank, thus avoiding the aging of the insulation material, improving the service life of the product also improves social benefits.

Product features

Energy Savings: The S11 type has an average 30% reduction in no-load losses compared to the GB/T6451. an average 25% reduction in load loss, and an average 20% reduction in operating costs.
Long service life: The transformer oil tank adopts a fully sealed structure, and the fuel tank and the box edge can be bolted or welded to death, and the transformer oil does not come in contact with air to extend the service life.
High operating reliability: Improvements are made to the components of the fuel tank seal, increasing reliability and improving the process level to ensure the reliability of the seal.
Small footprint The S11-M series transformer tank uses a corrugated plate radiator. When the oil temperature changes, the thermal expansion and contraction of the corrugated plate can replace the role of the oil conservator. The corrugated plate tank has a beautiful appearance and a small footprint.
