一种冷库舱壁电缆密封组件 技术领域
本发明涉及船舶舱壁电缆密封技术领域，尤其涉及一种冷库舱壁电缆密封组件。
背景技术
在船舶中，为了向各船舱提供电力及通信等，需要在舱壁上开设通孔供电缆通过。电缆穿过船舶的冷库等水密气密及防火要求很高的舱室的舱壁时，通常需要使用电缆填料函，以使通过处密封，从而确保安全。
目前在船舶冷库的舱壁上多是采用电缆填料函与钢制电缆穿舱件配合穿过冷库的钢壁、绝热材料及冷库围壁，并在通舱件位于冷库围壁一侧利用绝缘泡沫对端口进行热绝缘处理。钢制电缆穿舱件与冷库围壁直接接触，由于金属材料传导热能的较快，容易造成冷库的冷源流失，影响冷库的保温效果，并且在通舱件的端口使用的绝缘泡沫会影响冷库围壁的美观性，在电缆周部形成绝缘泡沫凸起。
发明内容
