Frequently Asked Questions
What is a Completely Self-Protected (CSP) transformer?
A Completely Self-Protected (CSP) transformer is equipped with built-in protection mechanisms against lightning, overloads, and short circuits. It includes an internal high-voltage fuse link, a low-voltage circuit breaker, and an external surge arrester, eliminating the need for external customer-installed protective equipment.
What are the primary applications for these single phase pole transformers?
These transformers are designed for outdoor pole-mounted distribution lines. They are widely used to supply electricity to lighting systems, agricultural production, and industrial plants in remote rural areas, scattered villages, railways, and urban power grids.
What is the difference between Amorphous core and CRGO core transformers?
Amorphous core transformers utilize an advanced alloy metal core that significantly reduces no-load losses (core losses) compared to traditional CRGO (Cold Rolled Grain Oriented) silicon steel cores, making them highly energy-efficient and cost-effective over their operational lifespan.
Can the primary and secondary voltage ratings be customized?
Yes. While our standard designs cover common voltages (such as 13800V/7967V primary and 120-240V secondary), we can customize the capacity, voltage ratings, tapping ranges, and other parameters to meet the specific requirements of your regional power grid.
What standard specifications do these transformers comply with?
Our transformers are fully designed, manufactured, and tested in accordance with international standards, specifically IEEE & ANSI C57.12.00, IEEE & ANSI C57.12.20, and IEEE & ANSI C57.12.90.
