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. Product

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.
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 integrity of the coil and iron core,
and the
