Winding insulation class denotes the dielectric strenght of
the insulation material used for winding.

Winding insulation class denotes the limit of temperature
rise on load condition.

Answer / a.hanumathu

winding insulation class is related to the capability of
short ckt of winding with other conducting part like
stator.and wndg temp class is related to ability of
conducting without melting or loose of insulation.

Answer / rvg

winding insulation classification is nothing but a group of
materials arranged in the order of insulation resistivity
in terms of Kv per mm.

winding temp. class is related to temperature withstand
capability of winding insulation.

Answer / koppu chowdaiah

winding insulation gives electrical&mechanical stability to the winding. based on the temperature class in winding the insulation will be provided.suppose temperature will be increased highly due to high currents,the winding will be damage.

Answer / sridharan

winding insulation class gives mechanical &electrical
stability to the machines whereas winding temperature class
sive warning to the machine

Answer / anand

insulation strength is associated with voltage rating

temperature class is associated with currents.bcoz here due to current losses increase n so temperature
