The waterproof method of the cable is generally divided into two types of longitudinal water blocking and radial water blocking. The longitudinal water blocking mechanism of the cable is that the data contain a water shrinkable data, and when water enters from the cable end or from the defect of the sheath, the data can shrink rapidly when water enters to block the water from being further dispersed along the longitudinal direction of the cable, thus the aim of longitudinal water blocking of the cable is fulfilled. The radial water blocking is mainly completed by extrusion of HDPE nonmetallic sheath or hot-pressing, welding and cold-drawing of metal sheath.
When installing a cable, it is often important to consider its lifetime, how to ensure its lifetime, since the cable is directly exposed, it is particularly important that the outer layer must be protected with something. The cable is composed of several or more lines, and the wires are all surrounded by the insulating adhesive tape for more than one circle, and two circles. And the professional mica tape is used for enclosing two layers, so that the compactness of the mica tape is ensured. The waterproof joint of the cable is wound with more than two layers of adhesive tapes, so that firm binding is ensured, the environment is protected, epoxy resin or other surface treatment is adopted, after the waterproof joint is completely dried before use, a layer of exposed heat shrinkage tube is surrounded, but in the long-term use process, especially in deep water, the existing cable is easily torn, the operation of the cable is influenced due to lower temperature, and therefore, the cold-resistant waterproof cable is provided.
