Product Description
High-voltage/low-voltage prefabricated substation (European-style box-type transformer) is a complete set of power distribution equipment. It is composed of distribution equipment composed of high-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering equipment, reactive power compensation equipment, auxiliary equipment and connecting parts. these components are pre-assembled in one or several casings to transfer electrical energy from the high-voltage system to the low-voltage system.
Pearl Electric European-style Box-type transformer is a new generation of complete set of transformer and distribution products developed on the basis of absorbing the advantages of similar products at home and abroad. It is combining the actual needs of current co-distribution. This product has the advantages of compact structure, small footprint, safety and reliability, and convenient installation. It can penetrate deep into the load center and transfer with the load center. Therefore, this product is very suitable for construction sites, oil fields, ports, terminals, high-rise buildings, highways, subways, airports, residential areas and other places.

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 no-load loss and the no-load current are reduced efficiently.
- We use Simulating Analysis in the core model design, so that we can calculate the frequency and size of the vibration exactly and avoid the core cavity resonance.
- Between core & windings, and core & frame, we use spring connection. Then the noise is lower 10 to 15dB than the standard.
LV Winding:
- LV windings, above 400 kVA capacity, are adopting superior foil conductors, thus to obtain better amper-turn balance and reduce more transverse magnetic flux leakage. Then to greatly improves transformer's anti-short circuit capability.
- The wise design of air passage within the winding, greatly increasing the winding's heat dispersion effect. It helps to decrease temperature rise and improve products' overload capability.
HV Winding:
- HV windings are made of superior copper-conductor wires. Adopting fiberglass to reinforced insulation.
- The HV windings are casting under vacuum and high pressure conditions with Germany HUBERS vacuum Cast Machine. In this way, transformer's resin can get the best penetration. It can also greatly reduce its partial discharge (partial discharge for 11kV product could be lower than 5pC).
- 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 anti-lighting capability.
