What is 10kV level S22-M series fluid-immersed distribution transformer?

The S22-M Series 10kV Fluid-Immersed Distribution Transformer is a state-of-the-art solution designed for efficient power distribution in industrial, commercial, and utility applications. Engineered to meet the highest standards of energy efficiency and reliability, this transformer series complies with global performance benchmarks while excelling in harsh environments such as petroleum, metallurgy, chemical plants, and dusty industrial zones.

Key Features

Advanced Core Design

Utilizes high-permeability grain-oriented cold-rolled silicon steel for the core, ensuring minimal magnetic loss and optimized energy conversion efficiency. The core adopts a fully inclined joint stacking structure, reducing flux leakage and enhancing overall stability36.

Low Energy Consumption

40% lower no-load losses and 15% reduced load losses compared to traditional standards (GB 6451-1999), achieving Grade 1 energy efficiency certification8.

Enhanced material selection, including B20R065 silicon steel and T1-grade copper windings, ensures ultra-low power dissipation and long-term cost savings6.

Robust Construction & Safety

Winding Technology: Non-impregnated corrugated oil ducts and compressed tape binding improve thermal management and mechanical strength3.

Tank Design: Sealed corrugated-wall tank eliminates the need for an oil conservator, preventing moisture and oxygen ingress. Vacuum oil-filling technology ensures moisture-free insulation for extended service life38.

Safety Protections: The units are equipped with pressure relief valves (30–2000kVA models) and optional gas relays for fault alarms or tripping3.

Low Noise Operation

Noise levels below 60dB and 20dB lower than national standards, making it ideal for urban residential and commercial areas8.

Environmental Adaptability

Suitable for high-humidity, corrosive, and dusty environments. The fully sealed design resists pollutants and ensures stable operation in coastal or industrial zones.

Applications

Industrial Power Systems: Ideal for metallurgy, chemical plants, textiles, and heavy industries.

Renewable Energy Integration: Supports photovoltaic, wind, and nuclear power grid connections.

Urban Infrastructure: Deployed in residential complexes, hospitals, schools, and commercial centers for stable power supply.

Harsh Environments: Dust-prone, humid, or coastal locations due to corrosion-resistant construction.

Advantages Over Competitors

Superior Efficiency: Outperforms S11 and S13 series with 25% lower no-load losses and 60–80% reduced no-load current.

Compact & Lightweight:

Advanced manufacturing techniques enable a 30% smaller footprint compared to conventional models.

Maintenance-Free Design:

Vacuum-sealed oil tank eliminates routine oil testing, reducing operational costs.
