Shanghai Electric Machinery Co.,Ltd.

1E class motor

Class 1E motors for nuclear power plants are required to meet the requirements of normal operation under normal environmental conditions and to perform expected safety functions under accident conditions.The main feature is that the design life of the motor is required to be 60 years, and the motor can drive the corresponding water pump to achieve the rated flow within 6 seconds under 80% of the rated voltage.And the motor can be started and operated under the earthquake condition.

Product range: 380-6600v, 75-1000kw

Industry status
Technical advantages

The company has the nuclear safety equipment design license and manufacturing license. The nuclear power motor products basically cover all main equipment supporting motors for nuclear power station, including all class 1E emergency diesel generators, more than half of the rod power M.G units, more than 80% of the main feed water pump motors, more than 65% of the circulating water pump motors and condensate water pump motors, becoming the large and medium-sized nuclear power station in ChinaThe main manufacturer of type a motor.

Unit 5 and 6 of Fuqing nuclear power plant:

Safety injection pump motor ylks450-4 500kW 6.6kV

Safety injection pump motor ylks450-4 355KW 6.6kV

After a series of aging tests, the 1E motor prototype for nuclear power station of our company has passed the earthquake test.Verify the design life of the prototype, and the motor can be started and operated under earthquake conditions after simulated aging.The reliability of the insulation system and the motor structure of our company is verified by the identification test of the prototype.
