\n\n\n\n
A100 kVA 11kV\/400V transformer is a critical component in electrical distribution systems, widely used in industrial plants, commercial facilities, rural electrification, and utility substations. It steps down medium voltage (11,000 volts) to a usable low voltage (400 volts) for distribution to equipment, buildings, and loads.\n\n\n\n\n\n\n\n
What Is a 100 kVA 11kV\/400V Transformer?\n\n\n\n
This transformer type is designed to convert11 kilovolts (kV) on the primary side to400 volts on the secondary. The power rating of100 kVA (kilovolt-amperes) defines its capacity to handle electrical load without overheating or performance issues. Depending on its design, this transformer can be oil-immersed or dry-type.\n\n\n\n\n\n\n\n
Price of 100 kVA 11kV to 400V Transformer\n\n\n\n
Theprice of a 100 kVA 11kV\/400V transformer typically ranges between$1,200 to $2,500 USD, depending on:\n\n\n\n
\n
Type: Oil-immersed vs. dry-type\n\n\n\n
Insulation level and efficiency rating\n\n\n\n
Core material (copper vs. aluminum winding)\n\n\n\n

How to Choose the Right 100 kVA 11kV\/400V Transformer\n\n\n\n
\n
Confirm the voltage compatibility with your incoming line (11kV)\n\n\n\n
Choose copper winding for better conductivity, aluminum for lower cost\n\n\n\n
For indoor use, go for dry-type; for outdoor, oil-immersed is more rugged\n\n\n\n
Ensure the cooling and protection class matches your ambient conditions\n\n\n\n
Look for BIS\/IEC\/ANSI compliance based on your region\n\n\n\n\n\n\n\n\n\n\n\n\n
Frequently Asked Questions (FAQ)\n\n\n\n
Q1: What is the typical lifespan of a 100 kVA transformer? A: Around 25-30 years with proper maintenance and environmental conditions.\n\n\n\n
Q2: Is copper or aluminum better for transformer windings? A: Copper has better conductivity and durability, but aluminum is more cost-effective.\n\n\n\n
Q3: Can I install a 100 kVA transformer indoors? A: Yes, a dry-type transformer is designed for indoor use with fire-retardant properties.\n","protected":false},"excerpt":{"rendered":"
