Water Cold Cable (English name: Water Cooled Cable, commonly known as hydro -cable) is a special cable used for large -current heating equipment. It is usually composed of three parts: electrode (cable head), wire, and external nursing sleeve.
Water -cooled cable repair
1. The iron and copper welding layer is milling on one end of the cold cable on the milling machine on the milling machine (the other end does not need to be left).When milling, pay attention to the national column milling cutter with the same size as the copper core line, and the pore pour 3 mRN ice 45 angle.2. Replace the rubber tube 1. Like rubber tube 2. Copper core wire 3, tube 4. Connection 5. Copper welding layer 6. Cable connecting column (1) Remove both ends of the water -cooled cable tube card 3, and the copper welding layer will be milling.5 The cable connecting pillar 6 is clamped on the tigers pliers, and the rubber tube 1 and the copper core wire 2 head the head hold the cable connecting the pillar 6 to pull out the damaged outer rubber tube 1.(2) Take the new rubber tube of the same model and length, cover the outside of the copper core wire 2, put the rubber pipe at the end of the non -milling copper welding layer on the cable pillar 6, and the upper card 3.
Water -cooled cable principle
Simply to say, because the current that the cable needs to pass is too large and the heat is too high, it is necessary to use water to cool the cable (referring to the connection cable from the capacitor cabinet to the inductive ring).
Water -cooled cable structure
Structural characteristics of water -cooled cables: Water -cooled cables are made of cylindrical -shaped by the center of the centers cooling water pipes, the surrounding wires, the rubber pipes outside the wire, and the outside of the rubber pipe.Composition of thermal layer and metal jacket layer.Most of the current water -cooled cable connection methods adopted in China are plate -type plane connections, and there are also imported water -cooled cable thread connections.The connection method has good conductivity and strong cooling water sealing performance.The characteristics of simplicity and commissioning are a good connection structure.The sealing ring material, processing accuracy, mechanical strength, and the level of the assembly point affect the key factor that affects the electrical conductivity of water -cooled cables and cooling water.The outer structure of the water -cooled cable is an elastic rubber hose of sealing and insulating, and the internal structure is a Condenous soft cable copper wire. The two are circulating cooling water to eliminate the phenomenon of the cable itself.Combined with the local water quality and water pressure, the cooling water flow pores on the cable joint should be appropriately customized to improve the water cooling effect.Especially when the hydraulic fluctuations are overloaded, the cable cooling effect is more ideal.Due to the good water -cooled effect of water -cooled cables, the current density of the cable reaches about 4A/mm2, which is doubled than the allowable current density than naked soft cables.
