graded insulation वाक्य

These sustainable features include sustainable concrete, high grade insulation and thermal control, a natural air cooling system, a natural light feature and waste minimisation and management during construction.
It is possible that a load element or the alternator winding itself might have graded insulation, with a lower insulation level near the terminal that is supposed to be at earth potential, like the frame of the alternator, particularly if it has a very high voltage output.
