Description

A water-cooled cable

technical field

The utility model relates to the technical field of cables combined with multi-strand busbars for transmitting large currents of electric furnaces, in particular to a water-cooled cable.

Background technique

The water-cooled cables in the prior art are composed of cable heads, copper cables and rubber sheath tubes, and are mainly used in some high-current equipment, such as submerged arc furnaces, intermediate frequency furnaces, electric arc furnaces, and monocrystalline silicon furnaces. At present, large-section water-cooled cables are assembled by multiple bare copper busbars of the same length through the cable head, and the water-through rubber hose is jacketed. The disadvantage is that during the bending and movement of the water-cooled cable, the bare copper busbars squeeze and rub against each other, causing premature damage. At the same time, due to the skin effect of current transmission, the bare copper bus bars are not insulated, which reduces the effective conductive cross-sectional area and directly affects the conductive efficiency.

Utility model content

The purpose of the utility model is to avoid the defects of the prior art that are easily damaged and the influence of the skin effect on the conductive efficiency, and provide a water-cooled cable, which effectively solves the defects existing in the prior art by setting a wiring and water cooling structure .

In order to achieve the above purpose, the technical solution adopted by the utility model is: the above-mentioned water-cooled cable is characterized in that it includes copper stranded wires, the ends of the copper stranded wires are connected with the copper heads of the water-cooled cables, and the copper stranded wires and the copper heads of the water-cooled cables A rubber tube is arranged on the outside, and the copper stranded wire is covered with an insulating material layer.

The copper stranded wires are of unequal length structure.

The inside of the hose is provided with a water-cooling channel.

The rubber hose is set on the outside of the copper stranded wire and the copper head of the water-cooled cable, and is fixedly connected by a fastening clip.

The insulating material layer is arranged on the copper stranded wire and between the copper stranded wire and the hose, and the insulating material layer is provided with openings for enhancing the water cooling effect on the side facing away from the axis of the water-cooled cable.

The beneficial effects of the utility model are: the above-mentioned water-cooled cable adopts bare copper strands of unequal lengths to manufacture pre-bent water-cooled cables, and since the space for bending and deformation of the copper strands is reserved, the copper strands in use are reduced. The wires squeeze and wear each other to prolong the service life. At the same time, the copper stranded wires are coated with insulating material to insulate the copper stranded wires from each other. The insulating material faces away from the water-cooled cable axis and opens holes, which reduces the influence of the skin effect on the conductivity and ensures the water-cooling effect, thereby improving Performance of water-cooled cables. It prolongs the service life of the large-section water-cooled cable, improves the conduction efficiency, and has a simple structure.
