Question

In order to do both floor and air bending (handle up, and handle down), the conduit shoe will have two different sets of sight marks in order to identify the angle being made

a. true
b. false

Answer 1

High-voltage wires are held by insulating connectors but are not wrapped in insulating material; the air acts as the insulator, and this statement is false.

Step-by-step explanation:

True or false: The high-voltage wires that you see connected to tall metal-frame towers are held aloft by insulating connectors, and these wires are wrapped in an insulating material.

The statement is false. While it is true that high-voltage wires are indeed held aloft by insulating connectors to prevent electrical currents from grounding, the wires themselves are typically not wrapped in insulating material.

Instead, they are left bare; the air around them acts as an insulator because it does not conduct electricity at the voltages used in power lines. In addition, the distance between these wires and any potential conducting surface is kept large enough to reduce the risk of electricity arcing.
