[Blank] is a special type of armored cable that is very popular for service installations and exposed wiring in adverse conditions. It typically has voltage ratings of 600V, 1kV, or 5kV.

(Note: To complete the task, the name of the specific type of armored cable would need to be filled in the blank.)

The special type of armored cable referred to in the question is a high-voltage transmission line. These cables are commonly used for service installations and in adverse conditions where exposed wiring is required. They have typical voltage ratings of 600V, 1kV, or 5kV.

Explanation:

The special type of armored cable that is being referred to in the question is called high-voltage transmission line. These cables are commonly used for service installations and in adverse conditions where exposed wiring is required. They have typical voltage ratings of 600V, 1kV, or 5kV.

High-voltage transmission lines are used for transmitting power over long distances, and they are often found in power distribution systems. They are designed to withstand high voltages and provide a safe and efficient means of transmitting large amounts of electrical power.

For example, in Figure 21.49 and Figure 23.26, high-voltage transmission lines are shown carrying 240-kV and 200-kV voltages, respectively. These lines are hung from grounded metal towers and utilize ceramic or glass insulators to provide insulation and resistance.
