Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of 100kva single phase transformer in China. If you're going to wholesale durable 100kva single phase transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
This 100kVA single-phase transformer is an ONAN oil-immersed overhead unit, the rated power of this transformer is 100kVA, it steps down 13.2kV medium-voltage input to 120/240 V split-phase grounded-neutral low-voltage output, supporting residential neighborhoods, agricultural sites, light-commercial facilities, telecom stations and off-grid solar power distribution.
Constructed with high-permeability grain-oriented silicon-steel core and premium enameled copper windings, this 100kVA single-phase transformer achieves ≥98.25% full-load efficiency with low no-load and load losses. Mineral-based insulating oil delivers reliable cooling and insulation. Its anti-corrosion galvanized or corrugated steel tank adopts outdoor-grade powder coating, resisting moisture, UV and mechanical impact for harsh outdoor conditions. Designed for single-pole or double-pole installation, the unit weighs 420-500 kg with compact cylindrical dimensions, compatible with standard utility mounting hardware. Operating ambient temperature ranges from -40 °C to +50 °C for diverse climates.
