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.
