Frequently Asked Questions (FAQ)
What is a Completely Self-Protected (CSP) distribution transformer?
A completely self-protected (CSP) distribution transformer is designed with internal protective mechanisms, including a load signal lamp and an HJ international cap breaker, which protect the system from overloads and faults without requiring external protective devices.
What standards do your single-phase pole transformers comply with?
Our transformers are manufactured and tested in strict accordance with recognized international standards, specifically IEEE & ANSI C57.12.00, IEEE & ANSI C57.12.20, and IEEE & ANSI C57.12.90.
Where are these transformers commonly installed?
They are ideal for pole-mounted installations to supply electricity for lighting systems, agricultural production, and industrial factories in rural areas, remote villages, railways, and urban power grids.
What is the difference between Amorphous core and CRGO core options?
Amorphous core transformers offer significantly lower no-load loss values compared to standard CRGO (Cold Rolled Grain Oriented) core transformers, making them highly efficient for modern power grids looking to reduce energy waste.
Can the voltage and capacity specifications be customized?
Yes, while we offer a standard product range capacity from 10 to 500kVA and standard primary/secondary voltage ratings, any technical parameters can be fully customized according to your specific grid requirements.
