東北防火電纜防火涂料施工前應將電纜外表的浮塵、油污、雜物等清洗、打磨潔凈，待外表單調后方可進行防火涂料的施工。電纜防火涂料施工選用噴涂、刷涂等辦法，使用時應充沛拌和均勻，涂料稍稠時，可用適量自來水進行稀釋，以便當噴涂為宜。施工過程中及涂層未干時之前，應防水、防暴曬、防污染、防移動、防曲折，如有損壞及時修補。關于塑料、橡膠外皮的電線電纜，一般是直接涂刷5次以上，涂層厚度為0.5-1mm，大約用量1.5kg/m,關于包裝有油紙的絕緣電纜，應先包一層玻璃絲布，再進行涂刷，如果在室外或許潮濕的環境下施工，應加配套罩面清漆。

人們將電線和防火電纜統一稱為電線電纜。電線和電纜之間，沒有且固定的概念差異，一般僅以日常經驗來進行差異。在狹義上，分為電線和電纜，電線和電纜一般都是由電線電纜導體、絕緣層和護套層三個部分組成。
