leader cable
Low (C2)Technical
Definition
Meaning
A guide wire or signal-conducting cable that allows a vehicle (especially an unmanned one) or a machine to follow a pre-determined path automatically.
In broader technical contexts, any control cable that guides or leads a mechanism along a set course, such as in automated guided vehicles (AGVs) or towing systems. Also used metaphorically for a guiding principle or source of information.
Linguistics
Semantic Notes
Almost exclusively used in technical engineering, logistics, and automation contexts. It's a compound noun where 'leader' functions attributively, meaning 'that which leads'. It is not related to a person who leads.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling follows regional norms for 'cable'. The term is equally rare in both dialects.
Connotations
Purely technical, with no cultural or connotative differences.
Frequency
Extremely low frequency in general language; used only within very specific industrial and engineering fields in both regions.

Examples
By CEFR Level
- [Too technical for A2 level. Use simpler phrase: 'The robot follows a wire.']
- The factory robot follows a special cable on the floor.
- A leader cable helps machines move in the right direction.
- The automated trolley is guided by a buried leader cable that defines its route through the warehouse.
- Engineers installed a magnetic leader cable to ensure precise vehicle positioning.
- The AGV system's reliability stems from its simple but effective leader cable guidance, which is immune to most environmental interference.
- Replacing the optical guidance with a physical leader cable reduced the system's error rate significantly.
Learning
Memory Aids
Mnemonic
Think of a dog on a leash leading you home. The 'leader cable' is like that leash, leading the machine on its exact route.
Conceptual Metaphor
PATH AS GUIDE: A physical cable metaphorically represents a predetermined, safe, and reliable path for an entity to follow.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'leader' as 'лидер' (a person). Think instead of 'ведущий' in the sense of 'guiding' or 'направляющий'.
- Do not confuse with 'electric cable' alone; the 'leader' component is crucial for meaning.
Common Mistakes
- Confusing it with 'leader' meaning a person (e.g., 'The team leader's cable').
- Using it in non-technical contexts where 'guide' or 'path' would suffice.
- Incorrectly pluralising as 'leaders cable' instead of 'leader cables'.

FAQ
Frequently Asked Questions
No. While it may conduct a signal, its primary function is guidance, not power transmission. It's a path-defining tool.
No, it is strictly an inanimate technical object. The metaphor 'a guiding light' or 'a mentor' would be used for a person.
No, it is a highly specialised term used only in engineering, logistics, and industrial automation.
Modern alternatives include laser guidance (LiDAR), inertial navigation, and computer vision systems, which don't require physical infrastructure.
