主要用途及使用特性
尼龍護套電線電纜比普通的PVC絕緣電線電纜具有更優(yōu)良的電氣和物理性能：
尼龍護套電線電纜具有較好的耐熱性，在高溫下運行失重小的特點，可以提高電線瞬時抗熱過載能力，可減緩或降低PVC組份的逸出或遷移。
尼龍護套電線電纜具有耐腐性和自潤滑性及耐油的特點。
與同截面的PVC絕緣電線電纜相比，尼龍護套電線電纜具有外徑小、重量輕、靜磨擦系數(shù)小和***等特點，可提高敷設(shè)中的安全性和適用性。
尼龍護套線額定工作電壓450/750V, ***應(yīng)用于家用電器、航空航天系統(tǒng)、建筑和照明,。
電纜的長期工作溫度為90℃或75℃，敷設(shè)的溫度不低于0℃，彎曲半徑應(yīng)不小于電纜外徑的4倍。

Description of the purpose and usage properties
The nylon sheathed cable has more excellences in physical and electrical performance than the PVC cable.
The cable has smaller outer diameter, lighter weight, less static friction coefficient than the same size of PVC cable, which greatly improve safety and convenience in installation and assembly of the cable.
It is self-lubrication, and has good resistance to corrosion, oil, acids, alkali, and moisture.
The cable is widely used in fixed installation, home appliance, lighting equipment, construction and aviation engine room with voltage up to 450/750V.
Its permitted long term working temperature shall be 70℃ or 90℃, installation temperature shall be over 0℃, and maximum bending radius shall be not less than 4 times of outer diameter of the cable.
