Question:
cross-linked power cable of the “cross-linked” mean ah?
Answer:
cross-linked polymer chemistry is a term
XLPE insulated power cables have excellent thermal - mechanical properties, excellent electrical performance and resistance to chemical corrosion, but also has a simple structure, light weight, not drop restrictions on the laying of the advantages is widely used in urban power grids, mines and factories of the new cable.
cross-linked polyethylene is the use of chemical or physical methods to the molecular structure of linear polyethylene into a three-dimensional network structure of cross-linked polyethylene, which substantially improved the polyethylene thermal - mechanical properties, and maintain excellent electrical performance.
cross-linked polyethylene insulated power cable conductors the maximum rated operating temperature of 90 ℃, compared with paper insulated cables, PVC insulated cables, polyethylene insulated cables are high, current carrying capacity of the cable is also further improved.
Of course, due process different, there are many types of cross-linked cables, product performance is also more varied selection should pay attention to.

交联电力电缆的“交联”是什么意思啊？
回答:
交联是高分子化学的一个术语
交联聚乙烯绝缘电力电缆具有{zy1}的热—机械性能，优异的电气性能和耐化学腐蚀性能，还具有结构简单、重量轻、敷设不受落差限制等优点，是目前广泛用于城市电网、矿山和工厂的新颖电缆。
交联聚乙烯是利用化学方法或物理方法使线型分子结构的聚乙烯转变为立体网状结构的交联聚乙烯，从而大幅度地提高了聚乙烯的热—机械性能，并保持了优异的电气性能。
交联聚乙烯绝缘电力电缆导体{zg}额定工作温度为90℃，比纸绝缘电缆、聚氯乙烯绝缘电缆、聚乙烯绝缘电缆均高，所以电缆的载流量也进一步提高。
当然，由于工艺不同，现时有很多型式的交联电缆，产品性能亦比较参差，选用时应注意。
