题：
电缆（YJV-5 * 6）是什么意思？

回答：
ZR阻燃Y型聚乙烯J型交联V-PVC护套YJV为铜芯，YJLV表示为铝芯，其中L为铝。 22表示铠装的铠装类型，而32表示。因此全称是：阻燃铜导体交联聚乙烯绝缘聚氯乙烯护套电力电缆4 * 16表示总共有四根铜线，其中每根导线的截面积16平方毫米
 
全名：电缆ZR-YJV22-4 * 16MM2ZR：阻燃----- YJV22：铜芯交联聚乙烯绝缘聚氯乙烯护套双钢带包裹铠装电力电缆-4 * 16MM2：4芯，每芯16平方毫米。
 
ZR-YJV22-4 * 16是ZR铠装阻燃电力电缆，YJV22铜芯聚氯乙烯绝缘钢带铠装聚氯乙烯护套电力电缆，4 * 16是4芯16（mm2）截面。
