Protector tubes perform their function typically between which two components?

Protector tubes play a crucial role in providing mechanical protection and housing for cables and conductors in electrical installations, specifically in the context of transmission lines and their supporting structures. The primary function of these tubes is to safeguard the insulated conductors that run between the transmission lines and steel towers.

When installed between transmission lines and steel towers, protector tubes help to prevent physical damage to the cables due to environmental factors, such as weather conditions, as well as from mechanical wear that could occur from movement or vibration. This protection is vital to maintain the integrity of the transmission system, ensuring reliable operation and minimizing the risk of electrical faults or outages.

In contrast, the other options, while they do involve key components of electrical systems, do not specifically relate to the protective function of tubes as it pertains to maintaining the safety and performance of conductors connected to transmission lines. Each of those combinations involves different functions and protective measures that don’t typically include the application of protector tubes in the same manner as described in the correct scenario.
