Varför inte vattenkyld kabel läcka?

Många enheter värms upp efter att de har använts länge, även kablar. Om strömmen är stor värms de lätt upp. Förekomsten av värme påverkar normal drift och livslängd. Den vattenkylda kabeln är en slags kabel som använder vatten för att svalna. På grund av värmeproblemet som löses är arbetsstyrkan och kapaciteten hos den vattenkylda kabeln mycket högre än den vanliga kabelns. Vi vet alla att vattnet vi ser varje dag är ledande, så varför läcker inte den vattenkylda kabeln? Vad är principen för en vattenkyld kabel?

Water-cooled cable is a new type of cable. The main feature is hollow water-through. It is generally a special cable used in high-current heating equipment for medium-frequency and power-frequency high-current transmission. It is usually composed of three parts: outer sheath, wire and electrode, which is also the cable head. For ordinary water-cooled cables, the electrodes are welded using copper tubes and copper bars, which are not closely connected to the equipment. The wires are twisted with bare copper wires and have a large bending radius. The outer protective casing uses ordinary rubber hoses, which have low pressure resistance. The casing and the electrode are fastened by ordinary clamps, and the airtightness is not very good, and water leakage is relatively easy. Therefore, do not use water-cooled cables that are of poor quality. For water-cooled cables, the electrodes are made of integral copper rods by turning and milling, and the surface has been passivated or tinned. The wire uses tinned copper stranded wire, or enameled wire, which is woven by a CNC winding machine, with a small bending radius and high flexibility. The outer sheath is a synthetic rubber tube with a reinforced interlayer, which has high pressure resistance. Between the casing and the electrode is the used copper clamp, which is fastened by professional equipment cold extrusion, and has good sealing performance and is not easy to leak. Therefore, the use of water-cooled cables is more safe and secure.
