二、使用特性
聲納用縱向水密電纜一般用在水密穿艙部位，在外護套破損情況下，依靠電纜護套及電纜內部密封填料來延緩進入電纜內部的水的流動速度，提高設備使用的可靠性。
The enterprise standard
Sonar with longitudinal watertight cable is generally used inwatertight wear tank parts, outer sheath damage cases,relying on the cable sheath and cable inner packing to delayinto the cable inside the water flow speed,improve the reliabilityof equipmentused.
三、主要性能The main performance
電纜芯數可根據用戶需要從1芯到37芯，電纜導體結構優先采用下表所示，導體電阻應符合下表規定。
Some cable core according to user needs from 1 to 37 core. cable conductor structure preferred as shown in the tablebelow. conductor resistance should comply with the regulations of the table below.
電纜導體金屬絲之間涂滿阻水膠，纜芯絕緣外的空隙填滿阻水材料，在內外護套與屏蔽(如有)之間涂滿陽水膠來延緩水的流動，另外在外護套內部密實繞包阻水帶，其材料特性為遇水會膨脹，填滿電纜縫隙，從而達到密封效果。電纜縱向水密封性能試驗:電纜-端開口放置在4.5MPa水壓下6小時不滴水。電纜經過1000次雙向彎曲(彎曲半徑250mm)，應不發生斷芯，且導體直流電阻、耐電壓試驗和絕緣電阻無明顯變化。
Cable conductor wire between the ful block water glue, cable core insulation outside block water material, fill the gap inthe inner and outer sheath and shielding (if any) between the full block water glue to slow the flow of water, the other internaldense outer sheath around BaoZu hose. its materia properties for the water swells. fil the cable aperture. so as to achievesealing effect.Longitudinal water sealing performance test: cable open end placed 6 hours don't drop under 4.5 MPa water pressure
Cable after 1000 two-way bending (250 mm) bending radius, should not break in the core, and the conductor dcresistance, resistance to voltage test and insulation resistance has no obvious change.
