Oil-Immersed Distribution Transformer Description
Preferred Product for Eco-Friendly & Energy-Saving Urban-Rural Power Grid Renovation
This Oil-Immersed Distribution Transformer—a high-performance Amorphous Alloy Distribution Transformer—adopts an oil-filled sealed structure, sharing the same working principle as standard sealed power transformers. The core of this Amorphous Alloy Distribution Transformer is made of amorphous alloy, a high-performance isotropic soft magnetic material composed of iron, nickel, cobalt, silicon, boron and carbon. It features low magnetizing power and no structural defects that hinder domain wall movement. The strip thickness of the amorphous alloy core is extremely thin (only 0.027mm), with the stacking factor reduced to 0.75~0.8 accordingly. Its resistivity is 3~6 times that of silicon steel sheets, and its hardness is 5 times that of silicon steel sheets. It should be noted that the amorphous alloy material used in this Amorphous Alloy Distribution Transformer is particularly sensitive to stress, requiring precise manufacturing processes for the Oil-Immersed Distribution Transformer.
Oil-Immersed Distribution Transformer Core Features
- Ultra-low No-load Loss:The Amorphous Alloy Distribution Transformer adopts advanced amorphous alloy core material, whose no-load loss is 60%-70% lower than that of traditional silicon steel core transformers. This advantage enables the Oil-Immersed Distribution Transformer to greatly reduce long-term operation energy consumption and electricity costs, aligning with the energy-saving needs of urban and rural power grid renovation.
- Multi-voltage Compatibility:This Oil-Immersed Distribution Transformer—a dedicated Amorphous Alloy Distribution Transformer—covers 6.3kV, 10.5kV, and 11kV rated voltage levels. It is suitable for various power distribution scenarios such as urban grids, industrial parks, and rural power networks, with strong versatility that eliminates the need for additional voltage-matching equipment.
- Reliable Oil-immersed Structure:The Oil-Immersed Distribution Transformer features a sealed oil-immersed design, which ensures excellent insulation performance and heat dissipation effect for the Amorphous Alloy Distribution Transformer. It can adapt to harsh working environments (high temperature, humidity, dust) and has a service life of over 20 years, ensuring long-term stable power supply.
- Low Noise Operation:The Amorphous Alloy Distribution Transformer has low magnetostriction characteristics. Combined with optimized coil winding and tank structure design of the Oil-Immersed Distribution Transformer, the noise level is controlled below 50dB(A), fully meeting the noise requirements of residential areas and urban built-up areas.
- High Short-circuit Resistance:The coil of this Amorphous Alloy Distribution Transformer is made of high-quality copper wire with tight winding structure, and the body of the Oil-Immersed Distribution Transformer is reinforced by anti-short-circuit design. It can withstand short-circuit impact without deformation and ensure safe and stable operation of the power grid.
- Easy Installation & Maintenance:The Oil-Immersed Distribution Transformer has a compact structure and light weight, and this Amorphous Alloy Distribution Transformer is equipped with complete accessories (oil level gauge, pressure relief valve, temperature controller), supporting on-site quick installation. Its sealed structure reduces the frequency of oil replacement and daily maintenance workload, lowering the later operation and maintenance costs for users.
