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 Electricis 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

Specifications Pearl 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 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.
