Frequently Asked Questions (FAQ)
Q: What standards do these power transformers comply with?
These transformers comply with several major national and international standards, including GB 1094 (Parts 1, 2, 3, and 5), GB/T25446-2010, GB311.1-1997, IEC 60076, and ANSI/C57.12.00.
Q: What are the rated high voltage options for these transformers?
The rated high voltage options include 10 kV (with 11, 10.5, 6.6, 6.3, or 6 kV variants) as well as 20 kV configurations, depending on the product model and specifications.
Q: What connection groups are available for the transformers?
The standard connection groups include Dyn11, Yyn0, or Dyn11/Yyn0. When the core is a three-phase column, the Yyn0 connection group can also be configured according to customer needs.
Q: Can I request custom high voltage tapping ranges?
Yes. While the standard tapping ranges are ±5% or ±2×2.5%, three-phase transformers with other custom high voltage tapping ranges can be provided based on specific user requirements.
Q: What is the standard insulation level and frequency of these transformers?
The insulation level is rated at LI75AC35/LI OAG5, and the system operates at a standard rated frequency of 50Hz.
