Amorphous-Alloy 3D Wound-Core Oil Transformer
Ultra-efficient oil transformer pairing amorphous-alloy cores with 3-D wound-core technology — no-load losses cut to a fraction of silicon-steel units (e.g. 100 kVA at just 60–75 W), 30–2500 kVA.
- Core built from amorphous alloy with 3-D wound-core technology
- No-load and load losses sharply reduced; major electricity savings in operation
- Stable and reliable — the 3-D wound core raises short-circuit withstand and overall stability
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The S(B)H□-M·RL series oil-immersed amorphous-alloy three-dimensional wound-core transformer combines the advantages of amorphous-alloy energy-saving material and green three-dimensional wound-core technology — a high-efficiency, energy-saving product. It complies with the GB/T 1094 series, GB/T 25446-2010 and GB 20052-2024.
