Product Description
\ BRIEF INTRODUCTION \
ABOUT CEEG'S SCRBH SERIES - The amorphous alloy dry-type transformer adopts CEEG's unique semi-encapsulated three-phase three-column patented technology. The heat resistance level is as high as the H level, and the main insulating material is as high as the C level. It has a stronger overload capacity and short-circuits resistance. The main models include SCRBH15, SCRBH17, and SCRB19, and have all obtained energy-saving product certification, first-class energy efficiency certification, earthquake resistance report, and various test certificates.
Attributed to its great capacity and product features, SCRBH series amorphous alloy power transformers are professionally built for places with low power distribution utilization and high requirements for flammable, explosive, and fire prevention, such as cloud computing data centers, rural power grids, high-rise buildings, commercial centers, subways, airports, power plants, etc.
\ FEATURES \
| 1. Using a high-quality amorphous alloy Nomex strip, the no-load loss is reduced by about 70%. |
| 2. The self-developed three-phase three-column structure covers a small area, and that ensures a much lighter-weight, easier installation. |
| 3. Vibration model simulation analysis is used to reduce noise effectively. |
| 4. Unique core suspension technology and end seal process to ensure low force on the core and low noise. |
| 5. Adopt a unique semi-envelope structure type with strong dustproof ability, high product insulation performance |
| 6. High mechanical strength, waterproof, and short circuit resistant. |

\ CUTTING-EDGE CORE TECHNOLOGY \
WHY COULD CEEG'S SCRBH SERIES TRANSFORMERS BE WIDELY CHOSEN?
INDEPENDENT PRODUCTION LINE -
Focusing on power transformer manufacturing for more than 30 years and CEEG has built multiple independent production lines including the essential amorphous alloy iron core and also developed an exclusive professional manufacturing process.
EXCLUSIVE PATENTED TECHNOLOGY -
CEEG's core technology of three-phase and three-column has been awarded the National patent, guaranteeing a much light-weight, and promoted our power transformer's capacity to a higher level, gaining recognition from our customers all over the world.
ADVANCED MATERIALS DEVELOPED WITH
DUPONT NOMEX® - CEEG has built a solid cooperative relationship since 1999 with DuPont, the pioneer in the global power industry. With the technology developed in cooperation with DuPont, CEEG applied the advanced insulation systems to the power transformers manufacturing, ensuring a longer using life-span, and lower no-load loss.

Certifications
\ CERTIFICATED & QUALIFIED \
SCRBH series amorphous alloy three-phase three-column dry-type power transformers have reached the GB 20052-2020, the first-level energy efficiency standard. And also gained energy-saving product certification, earthquake resistance report, and various test certificates, including the 3C, PCCC energy-saving, ISO-9001, ISO-45001, and ISO-14001 certificates.
CEEG's SCRBH series amorphous alloy dry-type power transformers have been widely adopted in key projects by customers from all over the world. Especially the mega construction projects led by pioneer enterprises like China Telecom, China Mobile, China Unicom, Petrochemical Company Limited, Beijing General
Research Institute of Mining and Metallurgy, etc.
\ DESIGN & MANUFACTURE PROCESS \
Based on more than 30 years of design, manufacturing, and experimental experience in the transformer industry, CEEG has developed a set of advanced three-dimensional + parametric design software, which can realize automatic design, cost optimization, and simulation.
Fully considering the requirements of the national and industrial standards, ensuring the advantageous design of products.
The high-voltage winding conductor is wound with a high-quality conductor and reinforced with long and short-cut glass fiber felt. Poured by the advanced Heidrich vacuum pouring system under vacuum. Effectively restrain the occurrence of partial discharge, and the partial discharge is ≤ 5pc.
The low-voltage winding adopts a high-quality foil conductor and is wound on an automatic foil winding machine. The foil winding machine adopts the patented technology of foil wire hydraulic energy-saving tension crimping device, high-precision detection of ±0.5mm, and advanced argon arc welding technology, which plays a key role in ensuring the quality of coil winding.
The iron core adopts a high-quality high magnetic conductivity-oriented silicon steel sheet, a 45° full oblique step lapping process, and the surface adopts special moisture-proof and rust-proof coating, which effectively reduces the no-load current and noise level.
\ USE & PACKING\
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 bolt fastening at the connection.
INSPECTION BEFORE OPERATION - Measure the DC resistance of high voltage and low voltage windings. Then check the grounding of the iron core to see whether the grounding is reliable and whether foreign matters are overlapping. Last to test the insulation resistance.
ENERGIZING - Before putting into operation, the transformer shall be put into trial operation under no-load, and the protection system shall be checked and adjusted after 3 times of impulse closing.
