Technical Specifications & Performance Data
Kampa’s high voltage transformer series covers a broad range of rated HV levels and power capacities, designed to meet various grid requirements. Typical voltage ratings include 66kV, 110kV, and 220kV, with MVA ratings tailored to your specific needs.
| Parameter | Details |
|---|---|
| Rated Voltage (HV) | 66kV / 110kV / 220kV |
| Power Ratings (MVA) | Customized as per application |
| Insulation Level (BIL) | Lightning Impulse Withstand Voltage (e.g., 350kV, 550kV) Power Frequency Withstand Voltage per IEC |
| Cooling Systems | ONAN (Oil Natural Air Natural) ONAF (Oil Natural Air Forced) OFAF (Oil Forced Air Forced) – based on MVA load |
| Temperature Rise Limits | In line with IEC 60076 standards |
| Voltage Regulation | On-Load Tap Changer (OLTC) Off-Circuit Tap Changer (OCTC) |
The insulation system is designed to handle high BIL (Basic Insulation Level) values, ensuring robust performance against lightning impulses and power frequency stresses. Cooling methods vary by transformer load and ambient conditions, from natural cooling (ONAN) to forced cooling (OFAF), guaranteeing stable operation even under heavy loading.
Voltage regulation is expertly managed with options for both OLTC, which enables voltage adjustments under load, and OCTC for offline tap changes, enhancing flexibility and grid stability.
For highly reliable HV power transformers, Kampa also offers solutions integrating advanced cooling and voltage regulation technologies. You can explore related equipment like our medium and high voltage power solutions for a comprehensive approach to your electrical grid needs.
