Case History
On February 10, 2015, our long-term South AfricanY required lightning impulse tests for their transformers. Nanao Electric successfully delivered a 900 kV impulse voltage generator within 20 days.

NAIVG Compliance Standards:

Software Interface:
NAIVG-DIMS3000B Cross-Section Measurement, Recording & Analysis Software Interface

Key translation choices:

1. Maintained Chinese standard codes with official English titles

2. Used proper hyphenation in technical terms (e.g., "Impulse Potential Generators")

3. Standardized measurement units (900 kV with space separation)

4. Kept software model name intact (NAIVG-DIMS3000B)

5. Applied consistent capitalization in standard references

Would you like me to refine any specific technical terminology

Certification Compliance
Full adherence to ISO 9001:2000 International Quality Management System.
