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. 13.8kV 13.2kV New Energy

using:- Ambient temperature: Maximum +40ºCMinimum -25ºC- Relative
humidity: At 25ºC, not higher than 95% for daily average humidity
and not higher than 90% for monthly average ambient temperature.-
Altitude: less than 1000 meters.- Seismic level: less than 3m/s2 at
horizontal direction and less than 1.5m/s2 at vertical direction.-
Installation environment: No obvious and heavy pollution, no
explosive and corrosive gas and dust, with good air ventilation and
no severe vibration and shock.(Note: if the application environment
is different from the above standard service conditions, please
contact us for customized designs.)Products' Features:- Fully
functional and reliable- Less investment, less land occupation,
quick effectThe 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
designThe 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 adaptabilityProvide a variety of shells for users to
choose, including ordinary steel plate shell, composite plate
shell, stainless steel plate, etc.- Rich structure and
flexibilityProcess 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.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 ISO4
