35kv Open Dry-Type Distribution Power Transformer

ABOUT THE NEW GENERATION OF OPEN DRY-TYPE TRANSFORMER CEEG's new generation of open dry-type power transformers made its debut at the SNEC exhibition in 2023, at the Shanghai International EXPO Center, and it drew a lot of attention from the whole industry.The open dry transformer for energy storage uses NomexT410 as the turn insulation while increasing the Nomex composite material made of side baffle Nomex aramid insulation material of high-temperature resistance, high mechanical strength, high electrical insulation, and high stability performance advantages, so that this transformer has low carbon, environmental protection, energy saving, and high-efficiency characteristics. Especially suitable for user-side energy storage occasions such as hospitals, smart parks, photovoltaic storage charging stations, and data centers.CEEG's superb production technology ensures this transformer's art-like appearance and solid performance quality. Hand in hand with DuPont, CEEG anchors the double carbon goal, jointly creating a green future, for the world to bring a higher quality of life. FEATURES . The winding adopts an open, surface non-encapsulated structure type, which could ensure a good heat dissipation effect and strong overload capacity.2. It adopts DuPont Nomex® VPI vacuum pressure impregnation insulation system, which has a compact structure and reasonable layout.3. It can withstand both 220°C high temperature and -40°C low temperature, with strong insulation performance and meet various energy storage environmental requirements.4. It has the characteristics of flame retardant, non-combustible and non-explosive, and is more suitable for hospitals, smart parks, photovoltaic storage charging stations, data centers, etc5. Especially built for user-side energy storage occasions.6. Configure transformer intelligent terminals and use the IoT cloud platform to achieve intelligent operation and management. CERTIFICATED & EXECUTION STANDARDS  CERTIFICATED-The open dry-type transformers for energy storage have reached the first-level energy efficiency standard of GB20052-2020 and won the 3C, PCCC energy-saving certification, ISO-9001, ISO-45001, and ISO-14001 certificates.EXECUTION STANDARDS- GB 20052-2020 power transformer energy efficiency limit value and energy efficiency levelGB/T 1094.1-2013 Power transformers - Part 1: General provisionsGB/T 1094.3-2017 Power transformers - Part 3: Insulation level, insulation test, and external insulation air gapGB/T 1094.5-2008 Power transformers - Part 5: Ability to withstand short circuitsGB/T 1094.10-2022 Power transformers - Part 10: Sound level determinationGB/T 1094.11-2022 Power transformers - Part 11: Dry-type power transformersGB/T 1094.12-2013 Power transformers - Part 12: Load guidelines for dry-type power transformersGB/T 10228-2015 Technical parameters and requirements of dry-type power transformer 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. TESTING  All products strictly control the production process and quality links, and conduct strict tests and inspections according to national standards and customized requirements before leaving the factory, including partial discharge inspection, lightning resistance and electric shock inspection, noise inspection, and other necessary inspection items. Advanced test and detection equipment and a perfect inspection and detection system ensure the high quality and high quality of products.
