The term almost invariably designated the highest voltage circuits on a given system.  “输电”，除了表示基本的远距离送电的功能外，也表示联接重要电厂和枢纽变电站的电网骨架。这个术语几乎总是表示一个给定系统中的最高电压等级。 Sentence Explanations The aluminum conductor appears to gaining popularity in certain areas, especially where there is little or no snow, ice or sleet loading problems. 铝导线在某些地区很受欢迎，尤其是那些几乎没有雪、冰或雨夹雪覆盖导线问题的地区。 Two new types of insulators for use in contaminated environments are the high leakage distance and fog insulators .两种在污染环境下使用新型的绝缘子是大泄漏距离绝缘子和防雾绝缘子。It is generally accepted by the industry that the insulation deterioration of suspension type insulators in contaminated atmospheres，to a large extern, is a function of the leakage distance of the insulator. 业内普遍认为悬式绝缘子在被污染大气环境下的绝缘退化在很大程度上与绝缘子泄漏距离有关。 This provide the line designer with insulator application margins not available in standard suspension type insulators.这给了线路设计师标准悬式绝缘子所没有的绝缘距离裕量。（直译）这给了线路设计师比标准悬式绝缘子更大的绝缘距离。（意译）margin：裕量 All double-circuit 345 kV lines have been b
