2012/3/28The correct insulation of the winding of a motor is determined by both the temperature rise in the motor and the temperature of the ambient air. If a motor is subjected to an ambient temperature higher than 40 o C, it must normally be de rated or a higher insulation class of material used. Note: motors are typically rated for class 'B' or 'F

Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.
