Frequently Asked Questions
What are the main applications of these self-protected distribution transformers?
They are primarily used to supply electricity for lighting systems, agricultural production, and industrial factories in rural, remote, or scattered villages. They are also ideal for pole-mounted distribution lines for railways and urban power grids.
Which international standards do your transformers comply with?
Our transformers strictly comply with standard industry regulations, specifically IEEE & ANSI C57.12.00, IEEE & ANSI C57.12.20, and IEEE & ANSI C57.12.90.
What capacity range do you offer for distribution transformers?
We offer transformer capacities ranging from 10kVA up to 500kVA for standard applications, with options for other specific capacities depending on custom requirements.
Can the primary and secondary voltages be customized?
Yes. Standard primary voltages range from 2400V through 34500GrdY, 19920V, and secondary voltages include options like 120/240V, 240/480V, 139/277V, and 600V. Any other specific voltage configuration can be custom-engineered.
What is the difference between your Amorphous core and CRGO core options?
Both core types offer distinct loss efficiency. Generally, the Amorphous core option provides significantly lower no-load loss compared to the traditional CRGO (Cold Rolled Grain Oriented) steel core, helping to reduce long-term operational energy waste.
What safety features are integrated into the Completely Self-Protected (CSP) models?
Our CSP models are equipped with an HJ international cap breaker along with a load signal lamp, ensuring reliable self-protection and real-time load status monitoring for distribution networks.
