In the 1990s,
the research personnel successfully developed 0.075mm
level H polyurethane single side excess weld mica tape
and level H polyurethane immersing paint, which are applied
to SS-6 & SS-8 type traction electric machine of Zhuzhou
Electric Machine Factory of Railway Ministry and the electric
machines produced by Xiangfan Dongfeng Electric Machine
Co., Ltd.
We specially developed T128,
T129 & T130 series of epoxy solvent-free trickle impregnating
paint and T127 polyester resin trickle impregnating paint
for Changsha Hitachi Automobile Electric Machine Co.,
Ltd. All the performance indices reach or surpass the
standards of imported products and satisfy the demands
of factories to localize the insulating paint.
T122B and T123F epoxy solvent-free trickle impregnating
paint are successfully applied to Fujian Mindong Honda
Electric Generator Factory.
Besides, T122-1B level F all-purpose type quick drying
solvent-free resin series and T120 level B epoxy solvent-free
trickle impregnating paint are widely used in Xiangtan
Electric Machine Co., Ltd., Xiangfan Dongfeng Automobile
Electric Machine Co., Ltd., Tianjin Daming Electric Machine
Factory, Tianjin Hoisting Electric Machine Factory, Changhang
Electric Machine Factory, Fenxi Machine Factory of China
State Shipbuilding Corporation and Shougang Electric Machine
Factory, etc.

| In
1982, IFC5 alternating brushless electric generator for
ship use of Siemens Company, introduced by China State
Shipbuilding Corporation, is produced in Wuxi Electric
Machine Factory in Jiangsu Province. Among it, several
major techniques such as the epoxy single side film excess
weld mica composite materials, revolving baking technology
and glass reinforced plastics pre-casting shaped loop
are carried out by us. In less than one year, our institute
successfully realized localization and reached the foreign
advanced level of the kin technology. Later, we paid much
attention to the research of insulating technology of
1000 voltage large-scale direct current electric machine,
and successfully developed the following products and
techniques: level F mica composite insulating materials
below 0.1mm, level B & F all-purpose quick drying
solvent-free resin and fashioned winding electric machine
insulating technique, etc. The insulating materials and
technology are applied to a large-scale electric machine
of some national key engineering program and achieved
success for one time. The above products and techniques
won 1991 National Torch New High Tech Award and Technology
Advancement Award of Chins Shipbuilding Research Institute.
In 1988, level F-B all-purpose quick
drying solvent-free resin and level F composite insulating
materials, developed by our center, are listed in the
national level Torch Plan Program by Torch Plan office
of State Science Commission, Wuhan Science Commission
and Wuhan Donghu Development Zone. Through over six
years of careful research of technical personnel and
many times of technical examination, the program was
finally checked and accepted by the state in June 1995.
The domestic experts in the field agree that the materials
have reached the level of the kin products abroad. The
single side excess weld mica foil (tape) fills up the
blank at home. In 1996, the center was decided as one
of the initial new high tech enterprises by Wuhan People's
Government and Donghu New High Tech Development Zone.
In 1997, level B & F 7122 series of insulating paint
won the silver prize of the National Torch New High
Tech and Product Exhibition Fair.
Considering technological innovation
as the guide & the enterprise strength as the backup
force, and insisting on the principle of "customers
believe the product quality & are satisfied with
the after sales service", we will provide insulating
materials of good performance and reliable quality,
special type of insulating materials, the research of
localization of imported products, and the experimental
test of insulating capability.
