YB() series products is a kind of set of equipment which assembles the MV switch apparatus, transformer, LV distribution equipment together according to fixed connection scheme. This series substation is suitable for neighborhood unit, hotel, large-scale work site and high building that the voltage is 12kV /24kV/36kV/40.5kV, the frequency  is 50Hz and the capacity is under 2500kvA.
Oil immersed pad-mounted transformer is suitable for 3.6kV up to 40.5kV power class.
These series of pad-mounted transformer is oil-immersed with power rating from 25 to 2500 kVA at 50/60 Hz power transmission and distribution system for power supply and lighting in industrial and agricultural field.
These pad-mounted transformer are produced with nominal Voltage in primary winding 6 up to 36 kV. Nominal Voltage in secondary winding is 0.22 up to 0.66kV.
Scheme and connection group of windings is optional: Dyn0,Dyn5,Dyn11,Yyn0  etc. according to customer demand it is possible to make transformers with different connection of the Voltage s and other construction solution.
Pad mounted transformer structure is divided into front and rear parts.The front parts is LV and HV cabin including high and low voltage terminals, load switch, no-load tap-changer, plug-in fuse, pressure relief valve, oil temperature gauge, oil level gauge.The rear parts is oil tank including transformer oil,iron core ,winding and current-limiting backup fuse.
YB() series products is a kind of set of equipment which assembles the MV switch apparatus, transformer, LV distribution equipment together according to fixed connection scheme.

Prefabricated Electric Mobile Centers (PEMC) are tailor made, factory assembled and tested electric centers designed and manufactured to satisfy every specific customer needs. The design is a modular one, which provides a high level of flexibility in order to cover a wide range of applications. That includes outdoor switching stations (up to 132kV), single transformer stations (up to 132kV, 20 MVA), multi-transformer stations or generating electric centers. In addition, a special arrangement for pressurized PEMCs can be provided for special applications in hazardous areas. The primary voltage can vary up to 132kV. However, the secondary voltage (for transformer station PEMCs) can be a medium voltage or a low voltage as per the customer requirements.
Prefabricated electric center is built on a hot-dipped galvanized base frame in such a way that the whole center can be liftted and carried as a single unit. Since these centers are tailor made, their contents vary depending on the specific needs of a customer. For example, a PEMC might contain some or all of the following: generator, transformer, metalclad switchgears, outdoor load bread switches or breakers, batteries and battery chargers, auxiliary transformers,
AC/DC distribution panels, fire detection systems, air-conditioning systems, and many other equipments.

Rockwell transformer Co.,Ltd. offer an environmentally responsible, high efficiency, safer choice. The units have high-fire-point fluid, providing fire safety benefits, and a projected life well beyond that of a traditional mineral-oil transformer. These efficient and cost-effective transformers use Envirotemp™ FR3™ fluid. Envirotran transformers are manufactured in 50 - 10,000kVA, in primary voltage classes of 11kV,15 kV, 25 kV and 35 kV.

kVA

50-20,000

Primary Voltage

Up to 34,500 V

Secondary Voltage

Three-phase, pad-mounted transformers, for use on underground power distribution systems, are best suited for commercial applications in public access areas and where underground service is required. These transformers meet modern design requirements for flexibility and provide a visually pleasing installation. Construction allows installation in locations accessible to the general public without the need for protective fencing or vaults. These units are ideally suited for apartment buildings, schools, hospitals, shopping centers, commercial buildings, or industrial sites.
