TWO NEW HIGH EFFICIENCY MOTORS SF710HV6D FOR POWER STATION

Two new high efficiency three phase induction motors type Sf710HV6D with output power 4000 kW, 6-pole and voltage 10500 V have just been produced in one of the factories of Cantoni Group, Emit S.A.,  to be installed in a new power station unit of 910MW.

The frames of these motors are steel welded, B3 mounted, with IC611 cooling system (built on pipe cooler), equipped with a lot of control and measuring equipment such as:

* built-in Pt100 sensors in winding stator and bearings together with transmitters R/I 4-20mA,

* vibration measurement system,

* current transformers mounted in the box of the stator winding terminals.

 

Apart from the above mentioned features, the motors have very low noise level (acoustic screens mounted on the motor), very low starting current, high efficiency and special construction of terminal box resistant to short circuits for the power 909 MVA (Ik"=50 kA, Ip=125kA) at nominal voltage 10,5 kV during the 0,2 s. time.
