电线电缆的国际命名标准(高温线,硅胶线)
电线电缆的完整命名通常较为复杂,所以人们有时用一个简单的名称(通常是一个类别的名称)结合型号规格来代替完整的名称,如“低压电缆”代表0.6/1kV级的所有塑料绝缘类电力电缆。电线电缆的型谱较为完善,可以说,只要写出电线电缆的标准型号规格,就能明确具体的产品,但它的完整命名是怎样的呢?
电线电缆产品的命名有以下原则:
1、产品名称中包括的内容
(1)产品应用场合或大小类名称
(2)产品结构材料或型式;
(3)产品的重要特征或附加特征
基本按上述顺序命名,有时为了强调重要或附加特征,将特征写到前面或相应的结构描述前。
2、结构描述的顺序
产品结构描述按从内到外的原则:导体-->绝缘-->内护层-->外护层-->铠装型式。
3、简化
在不会引起混淆的情况下,有些结构描述省写或简写,如汽车线、软线中不允许用铝导体,故不描述导体材料。
案例:
额定电压8.7/15kV阻燃铜芯交联聚乙烯绝缘钢带铠装聚氯乙烯护套电力电缆
“额定电压8.7/15kV”——使用场合/电压等级
“阻燃”——强调的特征
“铜芯”——导体材料
“交联聚乙烯绝缘”——绝缘材料
“钢带铠装”——铠装层材料及型式(双钢带间隙绕包)
“聚氯乙烯护套”——内外护套材料(内外护套材料均一样,省写内护套材料)
“电力电缆”——产品的大类名称
与之对应的型号写为ZR-YJV22-8.7/15,型号的写法见下面的说明。
