If an insulating material is operated beyond the maximum allowable temperature, its life is_____________?
Correct answer: B. drastically reduced
- A. drastically increased
- B. drastically reduced
- C. unaffected
- D. none of the above
Explanation
Insulation deteriorates rapidly when its temperature exceeds the permissible limit, reducing its dielectric strength and service life. This is why temperature rise is a key factor in machine design.
