Product Description
7500/10000kVA Three Phase Substation Power Transformer Dual Secondary 13800V to 7200Y/4160V ＆ 4160Y/2400V Outdoor Mobile Configuration ANSI IEEE Standards
Product Overview
Designed for mobile, utility and industrial distribution projects, this three phase sealed substation power transformer provides two medium-voltage output circuits from a 13800V primary source. The unit is rated 7500 kVA under KNAN cooling and 10000 kVA under KNAF cooling, with dual outputs of 7200Y/4160V and 4160Y/2400V for separate 5000/6650 kVA and 2500/3350 kVA load groups. Copper windings, silicon-steel core construction, Midel 7131 synthetic ester fluid, off-circuit taps and a full monitoring/protection package support specification matching, outdoor installation and project review.

Product Highlights
- Dual-secondary voltage architecture
One 13800V delta primary supplies both 7200Y/4160V and 4160Y/2400V secondary systems, allowing one transformer to support two medium-voltage distribution levels.
- Defined split-load capacity
The split secondary windings provide 5000/6650 kVA and 2500/3350 kVA under KNAN/KNAF operation, giving engineers a clear basis for downstream load planning. - KNAN/KNAF cooling flexibility
The transformer operates at 7500 kVA under KNAN natural cooling and reaches 10000 kVA when the cooling fan assembly is operating in KNAF mode.
- Qualitrol pressure-protection package
The Qualitrol rapid pressure rise relay detects sudden internal pressure changes and provides alarm or trip contacts. The Qualitrol pressure relief device helps release excessive tank pressure and improve transformer protection.
Standard Features
- Qualitrol Rapid Pressure Rise Relay: Detects rapid internal pressure rise and sends an alarm or trip signal.
- Qualitrol Pressure Relief Device: Releases excess internal pressure to protect the transformer tank.
- Oil Level Indicator: Displays the transformer oil level inside the tank.
- Nameplate: Displays key ratings and identification information.
- Temperature Controller: Monitors winding temperature and controls alarms, trips or cooling fans.
- Thermowell Housing: Houses the temperature sensor for monitoring transformer oil temperature.
- Terminal Box: Houses electrical terminals and connection components.
- Cooling Fan Assembly: Forces air through the radiator to improve cooling.
- Pressure Indicator: Shows the internal tank pressure for safe operation monitoring.
- Tap Changer: Adjusts winding taps to regulate the output voltage.
- Oil Temperature Indicator: Monitors the transformer top-oil temperature.
- Radiator Butterfly Valve: Isolates the radiator oil circuit during maintenance.
