An electric wire is the fundamental conduit for power and signals in our daily lives.
Palavra em 30 segundos
- A conductive core with an insulating cover.
- Used to transmit electricity or signals.
- Essential for home appliances and infrastructure.
Overview
- 1概览：电线（Electric wire）是现代电力系统的基础组件，主要由导电性能良好的金属（如铜或铝）制成，外层包裹着绝缘材料（如塑料或橡胶），以防止漏电和触电风险。2) 使用模式：在中文表达中，电线通常与“接”、“断”、“拉”等动词搭配。例如，安装设备时说“接电线”，修复损坏时说“修电线”。3) 常见语境：电线常出现在家庭装修、电器维修、工业生产及城市基础设施建设中。无论是墙壁里的暗线还是插座上的明线，都是电线应用的典型场景。4) 近义词辨析：电线与“电缆”容易混淆。电线通常指单根或几根导线，结构较简单；而电缆通常由多根绝缘导线组成，外层有保护层，用于大规模电力输送或复杂信号传输。

Padrões gramaticais
How to Use It
Notas de uso
The word '电线' is used in both casual and formal contexts. It is a general term for any wire carrying electricity. Ensure you distinguish it from specific cables like '网线' (network cable).
Erros comuns
Learners sometimes confuse '电线' with '电缆'. Also, avoid using '线' alone without context, as it might refer to string or thread.
Tips
Use correct verbs for wires
In Chinese, use '接' (connect) for installing wires and '剪' (cut) for trimming them. These verbs are essential for basic electrical tasks.
Always prioritize electrical safety
Never touch exposed wires with bare hands. Always check for damage before plugging in devices.
Electrical standards in China
China uses 220V standard voltage. Standardized household wiring is strictly regulated to ensure public safety.
Origem da palavra
Derived from the combination of '电' (electricity) and '线' (line/thread). It reflects the literal function of the object in modern electrical systems.
Contexto cultural
In China, electricity safety is a major topic in public education. Standardized wiring and the use of high-quality wires are emphasized to prevent common household fire hazards.
Dica de memorização
Think of the two characters: '电' (electricity) + '线' (line). It is literally a 'line for electricity'.
Perguntas frequentes
4 perguntas电线通常指结构较简单、导线较少的传输线，多用于家庭或小型电器。电缆则结构复杂、外层保护严密，常用于大型供电系统。
如果电线外皮破损，千万不要用手直接触摸，以免触电。应立即切断电源，并使用绝缘胶带缠绕修复或更换新电线。
塑料皮是绝缘材料，可以防止电流泄漏到外部。这样既能保护电线内部，又能防止人接触到带电体导致触电。
绝对不可以。乱拉乱接电线极易引发短路、火灾或触电事故，必须由专业电工按照安全规范进行安装。
