Frequently Asked Questions (FAQ)
Q1: How much load can a 150 kVA transformer support?
A1: A 150 kVA transformer can support up to 120–135 kW of load, depending on power factor and usage type. It’s suitable for small to mid-sized facilities.
Q2: Should I choose oil-type or dry-type for my 150 kVA transformer?
A2: If your installation is indoors and safety is a concern (like in hospitals or malls), dry-type is better. For outdoor or heavy-duty industrial use, oil-type provides better cooling and efficiency.
Q3: Can I use this transformer in areas with extreme temperatures?
A3: Yes, the 150 kVA transformer can be built with temperature-resistant insulation and cooling systems to perform reliably in harsh environments.
Investing in a 150 kVA transformer means choosing reliability, safety, and energy efficiency. Whether for expanding your factory power infrastructure or building a power distribution network for your commercial premises, this transformer offers the perfect balance of performance and affordability.
