high-tension
/'hai'tenʃn/
Definition
- Adjective:
- Subjected to or capable of operating under relatively high voltage: Describes electrical equipment, lines, or systems that are designed for or carry a high electrical voltage, significantly above the standard domestic level.
Usage
- The term "high-tension" is used attributively, almost always placed before a noun to modify it (e.g., high-tension wire, high-tension line). It is a technical term primarily used in electrical engineering and power distribution contexts.
- It indicates a potential hazard due to the high voltage, distinguishing such equipment from low-voltage systems.
Examples
- Adjective:
- Workers must wear special protective gear when repairing high-tension power lines.
- The substation converts electricity from high-tension transmission lines to a lower voltage for local distribution.
- A high-tension cable runs between the two towers.
Advanced Usage
- The term is often part of compound nouns in technical specifications. The hyphen is standard in this fixed compound adjective.
- "high-tension insulator": An insulator designed to withstand high voltages.
- Ceramic discs are commonly used as high-tension insulators on utility poles.
Variants and Related Words
- High voltage (n.): A more general noun phrase for the same concept. "High-tension" is the adjectival form.
- That equipment is designed for high voltage. (noun phrase)
- That is a high-tension cable. (adjective)
- HT (abbreviation): A common abbreviation in technical diagrams and schematics.
- Low-tension (adj.): The opposite, describing systems operating at relatively low voltage.
Synonyms
- High-voltage (adj.): Functionally synonymous, though "high-tension" is a more specific technical term in certain industries (e.g., power transmission).
Antonyms
- Low-tension
- Low-voltage
Notes on Different Meanings
- "High-tension" is a specialized technical adjective. It does not have the metaphorical meaning of emotional or situational "tension" (e.g., a high-tension drama). For that meaning, the phrase "high tension" (without the hyphen) is used.
- Compare:
- Technical: A high-tension wire. (hyphenated compound adjective)
- General: The meeting was filled with high tension. (noun phrase: a high level of tension)
