• kVA Ratings: 5-250
• High Voltage: 2.4 – 19.9 kV
• Bil: 150kV (max)
• Low Voltage: 600V (max)

kVA and Standard Voltage Offerings

• All standard tap configurations available.
• Dual voltage available in most combinations.
• Dual voltage with taps in higher voltage position only.
• Dual voltage: Highest BIL applies to both voltages.
• Additional voltages may be available, consult with factory.
• Impedance and loss options available in most designs.

Tanks:

• Lifting provisions are stainless steel pads recessed into the tank side.
• Hood is attached with stainless steel hinges and requires no special tools for removal.
• Recessed locking provision has a handy grip for opening the hood.
• Locking nut and backing plate are 300 grade stainless steel for long service life.

Bushings:

• Externally clamped with stainless steel studs and plated hardware.
• Internal leads are sized for bushing extraction in times of maintenance or repair.

Corrosion Protection:

• 100% of the padmount receives a paint finish that exceeds all IEEE requirements including 160 in-lb. impact, 2000-hour salt spray, 1000 hours QUV and 20 cycle SCAB.
• ERMCO developed a method to cure powder paint on the padmount tank cover without damaging the transformer internals giving ERMCO the only true 100% powder paint coverage.

Quality

• All electrical testing is per IEEE standards.
• Many other tests are made for control purposes such as, core loop loss and exciting current, coil ratio and polarity, oil properties, and multiple oil leak checks.

Warranty

• All ERMCO padmounts carry a full 2-year warranty.
• Coverage includes round trip transportation between the purchaser’s shipping dock and the repair facility.
