Oil-Immersed Distribution Transformer

scope of application：

Oil-immersed transformers utilize oil as the primary insulating medium and cooling medium,

featuring various cooling methods such as self-cooling, air-cooling, water-cooling, and forced oil

circulation systems. Key components include the iron core, windings, oil tank, oil reservoir, breather, explosion-proof pipe (pressure relief valve), radiator, insulating bushings, tap changers, gas relays,

thermometers, and oil purifiers. These transformers are particularly suitable for power grid upgrades

in urban and rural areas as well as industrial and mining enterprises, and are especially

recommended for use in modular transformers and prefabricated substation transformers. Product model description:

Power wan xiang Electric technological superiority：

Our company manufactures the S11-M three-phase fully sealed distribution transformer, an energy- efficient product featuring advanced performance technology, innovative manufacturing processes, reliable

structure, and aesthetically pleasing design. 1 、 The product's iron core utilizes high-quality, highly magnetic grain-oriented cold-rolled silicon

steel sheets. Compared to the Type 9 product of equivalent capacity, it achieves a 30% reduction

in no-load loss, over 30% decrease in no-load current, and noise reduction of 5-8 dB(A). 2、 The product coil adopts a novel winding method, featuring robust construction, high mechanical

strength, strong short-circuit resistance, and safe, reliable operation. 3 、 The product adopts a corrugated oil tank design, where the volume change of transformer oil is regulated

by the elasticity of corrugated plates. This eliminates the need for an oil storage cabinet, ensuring complete isolation between transformer oil and air, thereby extending the transformer's

service life. 4 、 Compact in size, occupying minimal floor space,

featuring an aesthetically pleasing design, and requiring

reduced maintenance. SH15 (SBH21/SBH25) series

Oil-Immersed Amorphous Alloy Distribution Transformer

The SH15-M series amorphous alloy oil-immersed transformers represent a next-generation energy- efficient product developed to meet market demands. Featuring a magnetic circuit constructed with advanced

amorphous alloy materials that exhibit superior magnetic conductivity and ultra-low specific losses, these

transformers can replace silicon steel core transformers in both outdoor and indoor power distribution

systems. Their technical specifications achieve industry-leading performance benchmarks domestically, demonstrating over 60% reduction in no-load losses compared to S11-type distribution transformers. The fully

sealed design ensures complete isolation of insulating oil and dielectric media from ambient air, enabling

reliable operation in humid environments. This innovative solution serves as an ideal power distribution

equipment for urban and rural power networks. The product's performance parameters comply with JB/T10318-2002 \"Technical Parameters and

Requirements for Oil-Immersed Amorphous Core Distribution Transformers\". Compared to the S11 model,

this product exhibits only 33% no-load loss while maintaining identical load loss characteristics. This

significantly reduces operational costs for users, demonstrating exceptional social and economic benefits. The 10kV-grade amorphous alloy core sealed distribution transformer developed by our company can

replace silicon steel core transformers and is widely applicable to both outdoor and indoor power distribution

systems. Compared with similar products, this transformer demonstrates significant improvements in technical

parameters including no-load loss, no-load current, load loss, operational noise, top oil level temperature rise, and high/low voltage winding temperature rise. It is particularly suitable for rural areas with low load rates and

insufficient power supply, as well as regions experiencing significant load fluctuations and challenging

maintenance conditions. Featuring a fully sealed structure, the transformer ensures insulation oil and dielectric

materials remain protected from atmospheric pollution, enabling reliable operation in humid environments. This makes it the most ideal distribution equipment for 10kV power lines in both urban and rural areas. 4
