Question

In case of overhead lines, normally ______ insulators are used at road crossings

• A. Strain type
• B. Pin type
• C. Suspension type
• D. Both Pin type and Suspension Type

Hint:

Strain insulators are ideal for locations with high tension or mechanical stress.

Answer 1

The Correct Option is A

Strain type insulators are typically used at points where the mechanical stress is high, such as road crossings, river spans, and sharp curve points in transmission lines. They are designed to bear high mechanical loads.
