The insulating material for cables should____________?
Correct answer: D. have all above properties
- A. be acid proof
- B. be non-inflammable
- C. be non-hygroscopic
- D. have all above properties
Explanation
Good cable insulation should resist chemical attack, absorb little moisture, and not readily support combustion. Thus acid resistance, non-hygroscopic behaviour, and non-inflammability are all desirable properties.
