Definition
- Adjective:
- High-tension, high-voltage: Describes an electrical system, line, or current that operates at a very high voltage, typically used for long-distance power transmission. It implies a high level of electrical potential that is dangerous and requires special safety measures.
Usage Examples
- Adjective:
- Đường dây cao thế rất nguy hiểm. (The high-tension power line is very dangerous.)
- Công nhân đang sửa chữa cột điện cao thế. (Workers are repairing the high-voltage electricity pole.)
- Khu vực này cấm lại gần vì có điện cao thế. (This area is forbidden to approach because of the high-voltage electricity.)
Advanced Usage
- "điện cao thế": This is the most common compound phrase, specifically meaning "high-voltage electricity" or "high-tension current." While "cao thế" is an adjective, it is almost exclusively used in technical contexts related to electricity, particularly in this fixed phrase.
- Tai nạn do tiếp xúc với điện cao thế rất thảm khọa. (Accidents from contact with high-voltage electricity are very tragic.)
Variants and Related Words
Điện hạ thế (n): Low-voltage electricity. This is the technical opposite of "điện cao thế."
- Hệ thống điện trong nhà thường là điện hạ thế. (The electrical system in a house is usually low-voltage.)
Trạm biến thế/Trạm biến áp (n): Electrical substation. This is a facility that transforms voltage, often between high-tension and low-tension levels.
- Trạm biến thế chuyển đổi điện cao thế thành điện hạ thế. (The substation converts high-voltage electricity to low-voltage electricity.)
Synonyms
- Điện thế cao: This is a more formal or technical synonym with the same meaning (high electrical potential). "Cao thế" is the more common, condensed form.
Important Note on Usage
- "Cao thế" as an isolated adjective is highly specialized. In everyday language, it is rarely used alone. It is primarily encountered in the compound term "điện cao thế". Using it alone (e.g., "Một đường dây cao thế") is understood but derives its full meaning from the implied context of electricity. It does not commonly describe other "high" states like pressure or tension in a metaphorical sense.
