Product Description and Application 产品描述和用途
Electricity-mark resistant black PE jacketing compounds for ADSS optical cables is specially designed for the jacketing of ADSS optical cables which synchronously lay with high-voltage power transmission cables. This product contains special additives so as to maintain the excellent electricity-resistant property and climate-resistant property. It also has good mechanical property, environment-cracking resistant, thermal deformation and excellent processability performances. This kind of compounds is suitable for the jacketing of ADSS electricity-mark resistant cables which exists in high-voltage environment. It also can be used in other situations which have electricity-mark resistant requirements.
ADSS光缆用耐电痕黑色聚乙烯护套料是专为与高压电力传输电缆同步敷设的ADSS光缆开发的一种专用护套料。它含有特殊的添加剂保证了其具有优异的耐电痕性能和耐候性能,它还具有优良的机械物理性能、耐环境应力开裂性能、耐热变形性及优良的加工性能。本材料适用于敷设在具有高压电场的恶劣环境下的ADSS抗电痕光缆的护套,也适用于其它具有抗电痕要求的场所。
