FAQ

Frequently Asked Questions

Expert answers regarding procurement, maintenance, and technical engineering of power distribution transformers.

1. What is the fundamental difference between oil-immersed and dry-type transformers?
Oil-immersed transformers utilize liquid mineral oil or synthetic ester for cooling and insulation, making them highly cost-effective and durable for outdoor substation layouts. Dry-type models use cast resin or vacuum pressure impregnation (VPI) for insulation, offering superior fire safety profiles that suit indoor installations in commercial centers or hospital projects.
2. How do amorphous alloy cores reduce operational costs compared to silicon steel cores?
Amorphous alloy cores feature a highly random atomic configuration. This structure drastically reduces magnetic friction during cycle switching, lowering no-load losses (hysteresis losses) by up to 70% to 80% compared to traditional silicon steel. This design leads to notable energy savings for utility networks that run continuously.
3. What field diagnostic tests are recommended for newly arrived transformers?
Key field diagnostics include insulation resistance checks, winding resistance measurements, voltage ratio verification, vector group checks, and Dielectric Oil Breakdown Voltage (BDV) tests. Performing these baseline tests ensures the core and winding assemblies remained secure and moisture-free during transit.
4. Can Henan Pirooz Power design custom voltage setups for specific industrial grids?
Yes, we provide fully customized transformer designs tailored to specific system configurations. We adjust primary/secondary voltages, impedance percentages, cooling configurations (ONAN/ONAF), vector configurations, and tap-changer options (NLTC/OLTC) to meet the requirements of your application.
