Pearl Electric Co., Ltd. was established in 1958, and engaged in
electric equipment research,development and manufacturing for 59
years. The main products cover:
10~220kV oil-immersed power transformer,
10~35kV dry type transformer,
10~35kV pad-mounted transformer,
pre-fabricated substation, reactor
and other power transmission and transformation equipment.
Project experience covers Asia, South America, Africa, Europe and
Pearl Electric is one of the four corporations with national
nuclear supply reference,
and ranks the third in sales of national solar power substation and
wind power substation.
2. Factory Area and Equipment
Pearl Electric covers a factory area of 105000 square meters, with
more than 72000 square meters of up-to-date workshop building.
The workshops are equipped with more than 600 units of modern
manufacturing equipment, advanced in China and abroad, such as the
fully-automatic vacuum resin-casting equipment imported from
Germany HÜBERS company, the automatic slitting lines for silicon
steel sheet manufacturing, 600mm automatic transverse shear line
for transformer core manufacturing, 500t electro-hydraulic servo
and numeric-control bending machine, etc..
The complete set of transformer testing equipment is equipped in
the test center, including the shielded measurement room for local
partial discharge and noise test. Pearl Electric has the capability
to carry out all the type tests and routine tests of 220kV and
below-220kV transformer (except the short-circuit test) within the
test center, thus greatly satisfying various test requirements for
transformer product research, design and manufacturing.

standard, and all tests procedure in accordance with referring
All materials and equipment used in the Facilities may be inspected
by the purchaser at any time.
All equipment is subjected to all routine tests set out in relevant
IEC standards, including any optional tests which the Project
Manager deems to be applicable.
One item of each type of plant is subjected to all type tests set
out in relevant IEC standards. Such tests may be waived in cases
where the supplier submits reports of type tests conducted by
third-party testing agencies and which are accepted by the Project
Manager as adequately demonstrating that the equipment complies
with the relevant IEC requirements.
