Federal Pacific medium voltage ventilated dry-type transformers include the voltage class range of 2.4 kV through 25 kV, BIL ratings of 20 kV through 125 kV, self-cooled, with power ratings below 5000 kVA. They can be installed outdoors or indoors in any suitable room that complies with the National Electrical Code spacing and ventilation.
Transformers are available in three-phase ratings from 15 kVA to 10,000 kVA and single-phase from 15 kVA to 3,000 kVA. All standard primary and secondary voltage ratings are provided to match load requirements to the distribution system.
Altitude: ≤ 2000 m.
Temperature range: -5 °C to +40 °C, and the average temperature within 24 hours should not exceed +35 °C.
The relative humidity should not exceed 50% at +40 °C, and higher relative humidity is allowed at low temperature (90% at +20 °C). And air must be clean.
Workplaces should be free of fire, explosion, serious pollution, chemical corrosion and severe vibration.
Gradient: ≤ 5°, vertical installation.
Temperature range of transportation & storage: -25 °C to +55°C, and the temperature can be up to +70 °C in short time (within 24 hours).
DAYA Medium Voltage 35kV Indoor Dry Type Transformer Parameter (Specification)
medium voltage transformers are regarded for their high level of quality and service reliability that has become synonymous with HPS transformer products. With three phase ratings up to 15 MVA, 34.5 kV, 175 kV BIL and single phase to 5 MVA, we feature the newest technology and manufacturing processes. These units can be offered for a variety of environmental conditions and are built to meet the most onerous duty requirements. In addition to conventional indoor applications, our dry units can be located outdoors, on drilling platforms, in network vaults and in every location where airborne contaminants pose a risk to electrical equipment.
Typical Applications include:
Power Distribution Stations
Utility Power Generation
Offshore Drilling Platforms
1. Cabinet part: all right-angled parts that operators may come into contact with are all reversed at R angles to prevent scratching and hurting people; the improved busbar frame is more convenient to install busbars and has a more beautiful appearance; the ventilation grid installed on the top cover has anti- Drip function; the top cover is an open structure, which is convenient for users to place horizontal busbars on site;
2. Drawer part: the drawer adopts double-folding positioning groove rivet riveting process, and all parts are molded at one time, so that the drawer is 100% interchangeable. At the same time, the double-folding and rivet technology solves the defects of sheet burr and self-tapping screw tip injury;
3. Connectors: The first-time plug-in for the incoming and outgoing lines of the drawer can be directly used in conjunction with the function board and the metal channel, and the secondary connector is convenient to connect and the wiring is beautiful;
4. Vertical channel: half functional board or iron rectangular channel can be selected, and can be easily interchanged.
