Question

Which of the following properties should NOT be present in the insulating cover used in the insulating line?
1. It should prove resistant to weather, UV, ozone, etc.
2. It should have enough electrical-tracking resistance.
3. It should have enough mechanical resistance to cold weather conditions.
4. It should be rigid and astatine-free.

Answer 1

Correct Answer - Option 4 : It should be rigid and astatine-free.

Properties of insulating cover used in the insulating line:

• It should have enough electrical-tracking resistance.
• It should prove resistant to weather, UV, ozone, etc.
• It should have enough mechanical resistance to cold weather conditions.

 

Solution:

From the given options, option 4 statement 'It should be rigid and astatine-free' should NOT be present properties of the insulating cover used in the insulating line.
