We manufactured a high speed towing streaner cable which is installed by hydrophones nade from Piezo-Rubber. The Piezo-Rubber type hydrophones have vollowing characteristics.1) Smoll diameter and long length hydrophone 2)Casing the Piezo-Rubber with rigid brass case 3) Polyurethane mounting rail allows mechanical isolation for cylindrical plastic case 4) Maximum depth of water 500m 5) Cancelling the flow noise around hydrophme if is proved that the manufactured streamer cable has a same high performance as a intended one,

我们制造了一种高速拖缆，它是由压电橡胶的水听器安装的。压电橡胶型水听器具有体积大的特点。1）小直径和长长度的水听器2）用刚性黄铜外壳包裹压电橡胶3）聚氨酯安装轨道允许圆柱形塑料外壳的机械隔离4）最大水深500米5）如果证明制造的拖缆具有与预期拖缆相同的高性能，
