S18-6300-180000kVA/110kv Oil-Immersed Power Transformer

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.The new high-temperature resistant transformer independently developed by CEEG adopts a mixed insulation structure, and the hot spot temperature part of the body uses DuPont's Nomex insulation material (grade C heat resistance) and mineral oil, which truly meets the operational requirements of "high overload, safety, and reliability" in the whole life cycle. This product is the best choice for users with special high requirements for transformers or renewal and transformation (capacity expansion and transformation on the basis of the original transformer).The no-load loss of the product is more than 10% lower than that of the current national standard gb6451-2015, and the load loss is more than 5% lower than that of the current national standard gb6451-2015. The performance meets the energy efficiency standard of gb20052-2020. The noise level of self-cooling is lower than the national standard. According to the needs of users, the advanced Nomex insulating material and transformer insulating oil of DuPont can be used to make the product performance meet the requirements of high overload, high service life, high reliability, high safety, and high capacity density. 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. CERTIFICATED & QUALIFIED S18 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.
