产品描述：SYWV(Y)-75系列物理高发泡聚乙烯绝缘电缆

SYWV(Y)-75型聚乙烯物理高发泡电缆是一种具有很低损耗的电缆，它是通过气体注入使介质发泡，选择适当的工艺参数使得形成很小的互相封闭的气孔，这种介质不易老化，不易受潮。

电缆内导体有纯铜线、铜包钢、铜包铝，外导体为铝塑复合带加镀锡铜线、裸铜线、铝镁合金线编织，介质和内导体相互牢固结合，当温度变化或电缆受拉压时，介质与导体之间不会发生相互移动。

SYWV(Y)-75型电缆的衰减比同尺寸的其它射频电缆小，它用于CATV闭路电视系统、传输高频和超高频信号，亦可用于数据传输网络，进行数据传输。

Product description:

SYWV (Y) -75 series of high physical polyethylene foam insulation cable. SYWV (Y) -75-high polyethylene foam physical cable is a very low-loss cables, it is through the media so that the gas injected foam, select the appropriate process parameters allow each other to form a small closed pores, which Media aging is not easy, not easy to damp.

    With a pure copper conductor cable line, copper clad steel, copper clad Aluminum, aluminum-plastic composite outer conductor for the increase in tin with copper, bare copper wire, aluminum-magnesium alloy wire weaving, medium and conductor with a strong combination with each other, when the temperature changes Or by cable tension and compression, media and the conductor does not occur between each move.

    SYWV (Y) -75 cable attenuation than with the size of other small radio-frequency cables, closed-circuit television system for CATV, high-frequency transmission, and ultra-high frequency signal can also be used for data transmission network for data transmission.

楼主是发布标准还是做广告啊,呵呵

有详细的资料吗？

好啊
