Why doesn't the Water-cooled Cable Leak Electricity?


Introduction to the Principle of Water-cooled Cables


Many devices will heat up after being used for a long time, and even cables will easily heat up if the current is large, and the occurrence of heat will affect normal work and service life.

Water-cooled cable is a kind of cable that uses water to cool down. Because of the problem of heating, the working strength and capacity of water-cooled cables are much higher than that of ordinary cables.

We all know that the water we see every day is conductive, so why doesn't the water-cooled cable leak electricity? What is the principle of water cooling cable?


 Water-cooled cable is a new type of cable. Its main feature is a hollow water passage. It is generally a special cable used in high-current heating equipment for medium-frequency and power-frequency high-current transmission. It usually consists of three parts: the outer sheath, the wire, and the electrode, that is, the cable head.

For ordinary water-cooled cables, the electrodes are welded with copper tubes and copper bars, which are not tightly connected to the equipment.

The wire is made of twisted copper bare wire, and the bending radius is large. The outer sheath is made of an ordinary rubber hose, which has low-pressure resistance. The sleeve and the electrode are fastened with ordinary clamps. The sealing performance is not very good, and it is easy to leak. Therefore, do not use water-cooled cables of poor quality. For water-cooled cables, the electrodes are made of integral copper rods by turning and milling, and the surface is also passivated or tinned.

The wire is made of tinned copper stranded wire or enameled wire, 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 sleeve and the electrode is the copper clamp used, which is fastened by cold extrusion with professional equipment, has good sealing performance, and is not easy to leak.

Therefore, it is safer and more secure to use water-cooled cables.
