4000kVA 22/6.6kV High Over-load Capacity Hermetic Oil Transformer
with in Wind TurbinesProduct's advantages- Low loss, low
noise, low partial discharge, high reliability- Powerful
anti-short circuit capacity, high anti-lightning impulse
capacity- HV coil is Vacuum casted with epoxy resin with
pressure, capabilities for better the cast without pressure.-
Simulating analys is being used in the core model, the resonance
can be avoided and the noise is reduced.- Simulation
calculation and analysis of lightning impulse wave are applied to
HV Coils; anti-lightning impulse capability is
improved.Certifications Company ProfilePearl Electric
Co.,Ltd.(Hereinafter referred to as Pearl Electric) located in
Panyu District, Guangzhou City, which is an enterprise mainly
engaged in the R&D and manufacture of power transmission and
transform.Pearl Electric, the former state-owned Panyu Electrical
Motor Factory established in 1958, To facilitate Company's
development, the Company was formally renamed as Pearl Electric
Co., Ltd. in January, 2010. Pearl Electric occupies a factory area
of 10.5 hectares, with more than 7.2 hectares of modern factory
building. Pearl Electric has more than 600 employees and more than
600 sets of specialized manufacturing equipment.Pearl Electric is
engaged in the research and development, production and operation
of dry-type transformers of 35kV and below, combined transformers,
prefabricated substations, reactors, oil-immersed power
transformers of 220kV and below , transmission and distribution and
Control equipment, etc. The annual output of transformers exceed 20
million kVA, and the pad-mounted products exceed 4000 sets.The
company is committed to providing customers with safe, efficient
and intelligent power transmission solutions, and has become a
leading enterprise in the domestic nuclear power dry-type
transformer and new energy box-type substation industry and a
leading enterprise in the environmental protection and
energy-saving transformer industry. Product

Electric's TechnologyCore:- 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. Packaging &
