Frequently Asked Questions (FAQ)
Q1: What standards do these distribution transformers comply with?
Our single-phase pole-mounted and completely self-protected distribution transformers comply strictly with international standards, specifically IEEE & ANSI C57.12.00, IEEE & ANSI C57.12.20, and IEEE & ANSI C57.12.90.
Q2: What is the capacity range of your single-phase pole-mounted transformers?
We offer a versatile product range with transformer capacities starting from 10 kVA up to 500 kVA to support diverse power requirements.
Q3: Can the primary and secondary voltages be customized?
Yes. While our standard designs cover common voltages (such as primary voltages from 2400V to 34500GrdY and secondary voltages like 120/240V, 240/480V, 139/277V, and 600V), we can customize the transformer specifications to match your exact grid requirements.
Q4: What is the difference between Amorphous core and CRGO core options?
We provide both core types. Amorphous core transformers feature significantly lower no-load loss (W) compared to CRGO core transformers, making them highly energy-efficient and cost-effective over long-term operations.
Q5: What applications are these completely self-protected (CSP) transformers designed for?
These transformers are ideal for providing electricity for lighting systems, agricultural production, and industrial factories in rural places, remote locations, and scattered villages. They are also highly suitable for pole-mounted distribution lines for railways and urban power grids.
Q6: What cooling method and frequency do these transformers support?
Our transformers utilize the ONAN (Oil Natural Air Natural) cooling type and support single-phase frequencies of both 50Hz and 60Hz.
