Product description 產品描述
This product is specially designed as extrusion semi-conductive shielding compound for PVC outer jacketing of EHV and high-voltage power cables. It has excellent mechanical property, electrical property and heat-resistant processability. Its extrusion surface is very smooth, well compatibly with PVC jacketing compounds, and tightly contacts with jacketing layers. It is an ideal compound which can well meet current customers’ need instead of graphite coating.
該產品是針對超高壓或高壓電力電纜PVC外護層專門設計的擠包型半導電屏蔽料。具有優異的機械性能、電性能，以及良好的耐高溫加工性能，擠出表面光滑，與電力電纜用PVC護套料相容性好，與護套層緊密接觸。適用目前客戶需求，代替石墨涂層的理想產品。
Processing Indicator 加工工藝
Recommend to process with the PE extruder. 建議使用聚乙烯專用擠出機進行加工。
