Final answer:
High-tension cables are frequently routed from the distributors to the spark plugs in flexible metallic conduits to provide protection, reduce electromagnetic interference, and enable easy installation and maintenance.
Step-by-step explanation:
High-tension cables, also known as ignition cables, are frequently routed from the distributors to the spark plugs in flexible metallic conduits for several reasons:
- Firstly, routing the cables in flexible metallic conduits provides them with protection against physical damage and prevents them from being exposed to extreme temperatures, moisture, and other environmental factors that could adversely affect their performance.
- Secondly, using metallic conduits helps to reduce electromagnetic interference (EMI) that can be caused by the high voltage in the cables. The metallic conduits serve as a shield, containing the EMI and preventing it from interfering with other electrical systems or equipment.
- Finally, flexible conduits allow for easier installation, maintenance, and replacement of the cables, as they provide flexibility and maneuverability when routing the cables through complex engine configurations.
