Dry Type
- Typically dry types go indoors due to the high flashpoint, non-flammable Nomex insulation.
- Dry types can also be installed outdoors in a specially designed outdoor enclosure to keep any blowing rain/wind/snow out of the enclosure. Our chief engineer always says a dry type transformer installed outdoors is only as good as the enclosure it’s in.
- Can be either round coil or rectangular coil – round coil is a better design for cooling and short circuit strength.
- Can be either disc or layer wound – disc wound is better for cooling.
- Degree C rise can be either 80 degree C, 115 degree C, or 150 degree C rise. 80 degree C runs the coolest and lasts the longest because insulation breakdown is what shortens the life span of a transformer, which is almost always caused by heat either thru overloading or harmonics.
- Standard dry type warranty is one year – ours is an industry best 5 years.
Dry type transformers are typically part of a line up with HV gear on one side and LV breakers on the other. - Elsco can do custom bus work for direct plug and play retrofit.
Padmount
- Green color.
- Lockable doors up front.
- Cable in from underneath the front compartment.
- HV & LV bushings both on the front side of the tank behind the lockable doors and separated by a steel HV-LV barrier.
- Tamperproof and stand alone (not part of a line-up).
- Outdoors applications. You will see then behind restaurants or malls.
Unit Substation
- Gray color
- HV & LV bushings on 180 degree opposite sides. Front side is where the gauges are. HV on left side and LV on complete opposite right side.
- Will have either full height terminal chamber, partial height air terminal chamber or throat covering the bushings.
- Usually part of a line-up with HV & LV gear on either side.
- Can be stand alone.
- Can be either outdoors application or indoor application with high flashpoint, less flammable fluid.
Station Type
- Gray color
- HV bushing top or cover mounted.
- LV bushings can be either top/cover mounted or side mounted.
- Outdoor applications.
- Due to exposed live parts, should be behind a lockable fenced in area.
Typically stand alone.
Benefits of Pre-Owned
Transformers
We maintain an updated inventory of both pre-owned copper- wound dry type and oil filled transformers. All units undergo a thorough certification process before we make them available for rent or purchase. This is a cost-effective way for your organization to access a reliable unit for a shorter period or temporary need.
