300 kVA Pad Mounted Transformer Features
This three phase pad mounted transformer is designed and manufactured in compliance with all applicable ANSI and DOE 2016 standards. It is oil-filled, 65°C temperature rise, and designed for usual service conditions per IEEE C57.12.00.
300 kVA ratings with primary voltages 2.4 to 335 kV (150 kV BIL) and secondary voltages up to 600 volts.
All standard tap configurations available: dual voltage in most combpinations, dual voltage with taps only (series connection only) and impedance and loss options available in most designs.
Standard Features
1. Small size and compact structure
2. Fully sealed, fully insulated, no insulation distance, and reliable personal safety.
3. It can be used in the looped network and can be used in the terminal. Conversion is very convenient, and the reliability of the power supply is improved.
4. Low loss, lower than S9 type transformer loss
Safety Protection Features
The cable connector can operate 200A load current, and can be used as load switch in emergency situations, and has the characteristics of isolation switch.
Double fuse protection, reducing operating costs.
The fuse of the plug-in fuse is a double-sensitive fuse (temperature, current); Delta/Y is used.
The connection method and the three-phase column structure have the advantages of high voltage quality, no drift of the neutral point, no heat generation of the cabinet, low noise, and good lightning protection.
