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.  CORE TECHNOLOGY  The active part adopts a high-temperature resistant hybrid insulation system, preferably matching parts, truly the same 30 years design of the life-span.Oil transformer all adopts the basic structural form of traditional transformer. The core is heart-type; the high-voltage winding adopts pancake-type coil; the low-voltage winding adopts wire-wound or foil-type coil according to different capacities. The biggest difference with the traditional transformer is the choice of high-temperature-resistant insulating paper. The insulation structure of 35kV and below oil-immersed power transformer belongs to the mixed insulation system, the wire turn insulation uses high temperature resistant insulating paper, and the insulation material with a lower temperature coefficient is used in the lower temperature parts.The oil-immersed power transformers use high temperature-resistant insulating paper as insulation material and use different temperature resistant grade insulation materials for different temperature parts according to the temperature field principle, so it has good temperature resistance performance and a large margin in the design.High-temperature resistant transformers can be safely operated in more than 40 ºC ambient temperature and do not affect their lifespan. It is safe and reliable even when operating at 20% overrated capacity. It provides a good solution to the problem of safe power supply during peak load periods.   Why choose us TECHNICAL ADVANTAGES  RESEARCH & DEVELOPMENT TEAM - CEEG has
