The world's first 110kV class 40000kVA 3D wound core transformer passed the sudden short circuit test

Recently, the world's first SZ11-RL-40000/110 on-load voltage regulating three-dimensional wound core power transformer developed by Haihong Electric Co., Ltd. passed the sudden short circuit test at the National Center for Quality Supervision and Inspection of Medium and Low Voltage Transmission and Distribution Equipment. All the items of special test, type test and routine test, all indicators are better than the national standard.

Haihong Electric Co., Ltd. adheres to independent innovation and focuses on the research and development of energy-saving three-dimensional wound core transformers. This product is the three-dimensional wound core power transformer with the highest voltage level and the largest capacity in the world at present. It is another breakthrough of Haihong Electric's energy-saving three-dimensional wound core technology in the field of 110 kV power transformers. It demonstrates Haihong Electric's strong innovation R & D strength.

The 3D wound core is a new type of transformer core, which adopts a three-phase symmetrical three-dimensional structure, which has the advantages of material saving, energy saving, low noise and environmental protection. The popularization and application of 110kV three-dimensional wound core power transformer is very suitable for the construction needs of smart power stations in urban power grids. It not only greatly reduces the loss of transformers, effectively reduces user operating costs, but also saves energy consumption, reduces air pollution, and brings considerable benefits to the society. economic and environmental benefits.
