Abstract
The utility model discloses a water-cooled cable in intermediate frequency heavy current. The water-cooled cable comprises at least one water-passing hollow metal spiral pipe, and a copper wire conductor is twisted outside the hollow metal spiral pipe; and an insulation layer and an outer protection sleeve are sequentially extruded and wrapped outside the conductor, and all the members are concentric. The water-cooled cable disclosed by the utility model has the following beneficial effects that: 1) eddy currents can be avoided, and the loss of electric energy can be reduced; 2) an ideal internal circulation cooling way can reduce the temperature increase of the conductor, which is caused by the heavy current all the way; and 3) the water-cooled cable is suitable for being used as a power cable for quenching furnaces, electric furnaces, arc furnaces, induction furnaces and the like in metallurgy and machining industries.
Description
Technical field
The utility model relates to a kind of water-cooled cable, is specifically related to water-cooled cable in the big electric current of a kind of intermediate frequency, belongs to the cable technology field.
Background technology
Immediate frequency cable in that equipment such as the quenching of metallurgy industry, manufacturing, induction furnace are used requires electric current big, and cable itself can in time obtain the circulation cooling, reduces eddy current loss, favourable economize on electricity simultaneously again.The connection request safety of cable and equipment, reliable.Used in the past cable technology often can not be taken into account.
Water-cooled cable can satisfy above needs in the big electric current of the intermediate frequency that the utility model provided.
The utility model content
The purpose of the utility model is for water-cooled cable in the big electric current of a kind of intermediate frequency is provided, to satisfy the requirement of above-mentioned immediate frequency cable.
The purpose of the utility model can realize through following technical scheme.
Water-cooled cable in the big electric current of a kind of intermediate frequency, it comprises the hollow metal helix tube of at least one water flowing, outside described hollow metal helix tube, twists system copper wire conductor; Conductor is extruded insulation layer and outer jointing jacket successively outward, and all members are all concentric.
Described insulating barrier also is provided with non-metal knitted reinforced layer outward.
The cooling water circular flow is through the cored screw pipe, therefore can satisfy cable " in cold " and " electric current greatly " requirement.
The utlity model has following beneficial effect: 1, can not produce eddy current, reduce electric energy loss; 2, the desirable interior circulation type of cooling has reduced the conductor temperature rise that big electric current one tunnel brings; 3, the glowing furnace, electric furnace, arc furnace, induction furnace etc. that are applicable to metallurgy, mechanical processing industry are as power cable.
Description of drawings
Fig. 1 is the utility model cross-sectional structure sketch map;
Among the figure: 1, cored screw pipe 2, conductor 3, insulating barrier 4, reinforced layer 5, oversheath.
Embodiment
Further set forth the structural representation of the utility model below in conjunction with accompanying drawing and specific embodiment.
Water-cooled cable in the big electric current of a kind of intermediate frequency as shown in Figure 1, it comprises the hollow metal helix tube 1 of at least one water flowing, strand system copper wire conductor 2 outside described hollow metal helix tube 1; The outer jointing jacket 5 of conductor 1 outer extruded insulation layer successively 3 and neoprene, all members are all concentric.
The described insulating barrier 2 outer non-metal knitted reinforced layers 4 that also are provided with.
The cooling water circular flow is through cored screw pipe 1, therefore can satisfy cable " in cold " and " electric current greatly " requirement.
Characteristics such as that this cable has is of many uses, long service life, failure rate is low, installation and maintenance are simple and convenient.
