Product Description BRIEF INTRODUCTION Favorable to meet the power
peak demands of summer, CEEG's oil-immersed power transformers are
suitable for distribution networks with high load rates under high
temperatures and places with shock load and continuous overload
requirements. Such as steel, metallurgical industry, railroad
transportation, power plant, hydropower station, etc.
FEATURES FEATURES LOSS LOSS LOW NOISE STABLE & RELIABLE
. 7-stage temperature control technology system, which
combined with the temperature field dinite element analysis, to
ensure full play to the performance advantages of various
insulation materials.2. The insulation system is based on
DuPont Nomex ® Insulation paper technology.3. Low noise:
Unique noise reduction measures are adopted in different parts to
ensure that the noise control is better than the national
standards.4. Low loss: The core is made of high-quality cold-rolled
silicon steel sheet with high magnetic conductivity, using the
Swiss core automatic laminating machine or longitudinal and
transverse shearing, multi-stage full-slant seam automatic
laminating, core tying using overall pressure and PET tape tying
process, effectively reducing the no-load loss and no-load current
of the transformer.5. No leakage: The oil tank and oil storage
cabinet have been tested for positive and negative pressure to
ensure that there will be no oil leakage during normal operation.
The components are installed with a flange groove structure, and
all seals are made of high-quality once-formed acrylate rubber
parts to prevent il-leakage.6. Strong short circuit resistance: The
transformer coils are calculated with reasonable ampere-turn
balance and semi-rigid copper wire is used. The core claiming parts
are calculated for strength and stiffness to meet the safety
requirements of maximum short-circuit mechanical force. The winding
pads are all densified and made of high-density rigid cardboard and
adopted integra set & integral pressing to ensure the accuracy of
assembly and the short-circuit resistance.SZ11-2000~40000/35

Certifications CERTIFICATED & QUALIFIED S13-M series
oil-immersed power transformers have passed the test of the
National Transformer Quality Supervision and Inspection Center, and
all indicators have reached the advanced level of domestic and
international products. The performance indicators meet the energy
efficiency requirements of GB20052-2020 and also won the 3C,
PCCC energy-saving certification, ISO-9001, ISO-45001, and
ISO-14001 certificates.CEEG's oil-immersed power transformers have
been widely adopted in key projects by customers from all over the
world. For example, they have been chosen to serve in the
construction projects of Beijing China Coal Electric Co., Ltd.,
Shenhua United Construction Co., Ltd., and Chongqing Yuzhan
Electric Co., Ltd.Our Advantages TECHNICAL ADVANTAGES
RESEARCH & DEVELOPMENT TEAM - CEEG has established a
strong technology R & D team, with technology R & D platforms such
as a postdoctoral workstation, Jiangsu Power Transformation
Equipment Engineering Technology research center.CLOUD PLATFORM
- It integrates the functions of electromagnetic optimization
design, parametric drawing, performance analysis, structural
optimization, and automatic drawing of the transformer, so as to
realize the sharing of transformer design resources, search,
modification, and version control of various data
information.INTELLIGENT OPERATION & MAINTENACE PLATFORM - Online
power quality analysis and fault alarm can be realized by
collecting key data such as transformer temperature, current,
voltage, vibration, and grid harmonic, and can be installed on
mobile phones. USE & INSTALLATION SERVICE CONDITIONS - The
installation site shall not be flooded by water, the altitude shall
not exceed 1000m, and the ambient temperature shall not be higher
than 40ºC. The relative humidity is 100%, and the environment is
40ºC to -25ºC (-25ºC requires an on-load tap changer and
temperature controller).PACKAGING & TRANSPORTATION - The products
can be partially disassembled and transported (such as on-load tap
changer, temperature controller, air cooling device, enclosure,
etc. can be packaged separately) or packed as one piece in
packaging boxes for transportation.VISUAL INSPECTION BEFORE
INSTALLATION - After opening the package, remove the protective
device and check the external conditions, especially paying
attention to the mechanical int
