Product Description

Key Advantages of Transformers Below 35kV

1. High Efficiency & Low Loss

• Amorphous alloy cores cut no-load loss by 70%+ vs. traditional models; new silicon steel sheets reduce losses by 10-20%, meeting GB20052-2020 standards and CQC certification.
• Low noise (e.g., 49dB for SCBH15) via optimized magnetic design, minimizing environmental impact.

2. Strong Anti-Short-Circuit Design

• Reinforced windings (copper foil/spiral structure) and balanced ampere-turn distribution enhance mechanical strength and short-circuit resistance.
• Stable mechanics: Positioning mechanisms and locknuts prevent displacement/loosening, enabling maintenance-free operation.

3. Reliable & Versatile

• Oil-immersed: Vacuum oil injection for stable insulation; sealed tanks with corrugated radiators suit humid/polluted environments (e.g., metallurgy).
• Dry-type: Fire-retardant epoxy windings, oil-free design, ideal for high-rises/airports; moisture-resistant, direct load-center installation.
• Wide adaptability: Operates in -25°C~+40°C, ≤1000m altitude, with anti-corrosion surface treatments.

4. Long Life & Low Maintenance

• No-core-lifting design; sealed tanks (oil) or oil-free structures (dry) eliminate regular upkeep, reducing costs.
• Durable materials (amorphous alloy, high-temperature wire) ensure 30+ years of service with minimal heat/magnetic loss.

5. Eco-Friendly & Safe

• Green materials: Recyclable cores, RoHS-compliant insulation, and reduced carbon/noise emissions.
• Safety: Flame-retardant dry types; pressure relief valves in oil types prevent faults, meeting international standards (IEEE C57.12.01).

Applications

Suitable for substations, industry, commercial centers, renewables, metallurgy, petrochemicals, and fire/moisture-sensitive sites, combining efficiency, reliability, and environmental benefits.
