As sharply increasing of global energy consumption, the consumption of conventional resource like coal, oil, natural gas are accelerating. People's awareness of the importance of energy saving, environmental protection and pollution-free is gradually incresing. With the technology advances, Using new energy and renewable energy become a sustainable energy road that the world must take.Wind energy and solar energy, as inexhaustible clean energy sources, have been rapidly developing in China.
The vigorous development of my country's wind power generation and solar photovoltaic power generation market has promoted the rapid formation of related supporting industry chains.
On the basis of the original design and manufacturing technology of Pad-mounted transformers and Prefabricated substations, Pearl Electric as one of the main suppliers of domestic wind power generation and solar photovoltaic power generation step-up equipment market.Combining the wind turbines and solar photovoltaic inverters and requirements for step-up equipment in relevant power transmission and distribution networks, we has developed new substations for new energy power generation.
They have been widely used in major power generation companies and in various environmental conditions. Now we want to bring our technology and products to all parts of the world to jointly support the world's low-carbon environmental protection cause.
Wind Power Generation 2750kVA 35kV Pad-Mounted Transformer
Pad-Mounted Transformer (commonly known as American transformer, Combined transformer ) is a complete set of power transformation and distribution equipment. It places the transformer body, high voltage load switch, protective fuses and high and low voltage wiring in a common fully sealed oil tank. At the same time, it is equipped with a complete set of operation monitoring instruments (pressure gauge, oil level gauge, oil temperature gauge, etc.), and then combined with the low-voltage power distribution device.

Products' Features:
- Fully functional and reliable
- Less investment, less land occupation, quick effect
The product adopts a closed design as a whole, the shell can be grounded, and no insulation distance is required, which fully guarantees personal safety.
The transformer room can be equipped with a protective net to prevent accidental entry into the transformer room.
- Excellent temperature rise and heat dissipation design
The shell adopts a special ventilation structure, and the optimized design makes the product have a stronger heat dissipation capacity. The temperature rise level of the shell meets the requirements of the highest level of 10K specified by the national GB standard and the international IEC standard.
- Excellent environmental adaptability
Provide a variety of shells for users to choose, including ordinary steel plate shell, composite plate shell, stainless steel plate, etc.
- Rich structure and flexibility
Process Technology:
Core:
- Our transformer's core is made of high quality cold rolled grain oriented silicon steel sheet with high magnetic permeability. It is using full 45° slope lamination, so that the noload loss and the no-load current are reduced efficiently.
LV Winding:
- LV windings are adopting superior foil conductors or made of 100% copper wire, thus to obtain better amperturn balance and reduce more transverse magnetic flux leakage. Then to greatly improves transformer's anti-short circuit capability.
- Excellent design of oil passage structure, greatly increasing the coils' heat dispersion effect. It helps to decrease temperature rise of the LV winding and improve transformers' overload capability.
HV Winding
- HV windings are made of superior copperconductor wires. Adopting fiberglass to reinforced insulation.
- HV windings are adopted optimized structure to improve transformer's distribution of electric field.
- We use our existing technology calculate and analysis Lightning wave process simulation. Then substantially improving product's antilighting capability.
Insulation construction:
- Aclass level Insulation construction. The high-voltage coil and low-voltage coil are placed with the same center. Between the coils, use the thin paper cylinder with little oil clearance construction.
Tank:
- The tank is jointed with highquality steel. The surface is eliminated rust phosphate coating and painted with the type of FVC anticorrosive paint. It has ability to prevent the corrosion from oil and chemical matter. It can be broadly applied to outdoors with bad environment for its contour artistic, easily installation and maintenance free.
Components:
- All the power transformers equipped with highvoltage bushing, low-voltage bushing, oil-relesase valve earthling boilt, lifting board, name plate, pressure vale and so on. The transformers which are over 800kVA are equipped with signal thermometer and gas relay.
Certificates:
We have established a sound quality management system, and have passed the certification of ISO9001:2015 quality management system, ISO14001:2015 environmental management system, and ISO45001:2018 occupational health and safety management system.
In order to ensure product quality and in order to meet the development and supply of our dry-type transformers in overseas international markets, we all participate in type and special tests of internationally recognized independent testing laboratories, and obtain relevant reports.
