FAQ
 

Q1: What application scenarios is the Oil Immersed Transformer suitable for?

A: It is suitable for high-voltage transmission and distribution, industrial production facilities, substations, and other environments that require high load capacity and excellent heat dissipation performance.
Technical Advantage: With 18 years of industry experience, we use a three-dimensional wound core technology to reduce no-load losses by 15% compared to traditional lamination processes, while achieving ±0.5mm precision stacking to ensure long-term stable operation.
User Case: In a large steel plant expansion project, our oil immersed transformer (5000kVA) ensured the stability of continuous power supply thanks to its high load tolerance and low loss characteristics.

Q2: What parameters should be considered when choosing a Dry-type Transformer?

A: Key parameters include rated capacity (50kVA-5000kVA), voltage level, and temperature rise limits.
Core Advantage: We use epoxy resin + fiberglass insulation materials, with a fire resistance rating reaching UL94 V-0 standard, making it ideal for high-safety environments such as shopping malls and hospitals.

Q3: How does an Amorphous Alloy Transformer reduce electricity costs in remote areas?

A: By using amorphous alloy tape cores, no-load losses are reduced by 50%-70% compared to traditional silicon steel transformers, making them particularly suitable for rural grids with fluctuating loads.
