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

TechnologyCore:For using the "three-phase five-column" structure,
frame structure and the scientific design, the core would
beprotected from the applied stress and keep it's no-load
capability. The core cavity resonance will be avoided by
thesimulation analyzing of core model in the design process, and
calculating the vibration frequency & size exactly. Special noise
damping materials would be used to the products. Through above
measures, the noise of the amorphousalloy transformer will be
reduced efficiently.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.
