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 is 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.Our 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.Annual Production

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. FAQQ: Are you a
