                                                            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光纜用耐電痕黑色聚乙烯護套料是專為與高壓電力傳輸電纜同步敷設的ADSS光纜開發的一種專用護套料。它含有特殊的添加劑保證了其具有優異的耐電痕性能和耐候性能,它還具有優良的機械物理性能、耐環境應力開裂性能、耐熱變形性及優良的加工性能。本材料適用于敷設在具有高壓電場的惡劣環境下的ADSS抗電痕光纜的護套,也適用于其它具有抗電痕要求的場所。
