Abstract
The utility model discloses a waterproof control cable comprising a cable core, a gap of which is filled with a filling layer. An outermost layer of the cable is wrapped by an outer sheath sleeve in an extruded manner. A first water-blocking layer, an inner lining layer, a second water-blocking layer, a metal armoring layer, and a third water-blocking layer are sequentially disposed between the cable core and the outer sheath. The cable core is formed by intertwisting three insulation cores together. Each of the insulation cores is formed by a conductor, which is wrapped by an insulation layer and a shielding layer in an extruded manner. The waterproof control cable is advantageous in that the structure is simple and reasonable, the production is easy, and the costs are low; the waterproof performance, the anti-interference performance, and the electrical performance are excellent; the cable is used for the automatic construction of the hydropower station, and the safety performance of the automatic operation system can be improved, and the good application value as well as the wide market prospect can be provided.
Description
Technical field
The utility model relates to the power cable field, specifically refers to a kind of control cables with three layers of waterproof construction.
Background technology
According to the national energy development plan, country invests money in developing water power by emphasis from now on, in the upper reaches of the Yellow River, main master stream, the Changjiang river builds a collection of modern hydroelectric station.The automation degree of equipment that power plant construction adopts improves, all by computer control, so requirement must be waterproof to cable.The general control cable used at present adds insulating barrier by conductor and sheath forms, water resistance is poor, interference free performance is not strong, the proof voltage ability also can be affected, bring certain hidden danger to many equipment normal operations, cause the generation of some accidents, so need a kind of special control cables with water resistance requirement of development.
The utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned cable exists, and provides that a kind of water proofing property ability is good, antijamming capability strong, the good waterproof control cable of proof voltage ability.
A kind of waterproof control cable described in the utility model, comprise cable core, gap at cable core is provided with packed layer, at the cable outermost layer, extrudes the outer jacket cover, is provided with successively the first water blocking layer, inner covering, the second water blocking layer, metal armouring layer and the 3rd water blocking layer between cable core and oversheath.
Described cable core is by stranded the forming of three eradication edge cores; Its insulated wire cores is by conductor and is extruded in conductor outer insulating barrier, screen and forms.
Described screen is proof copper-wire braided layer or copper strips lapping layer or the rich covering of aluminium-plastic tape.
The beneficial effects of the utility model are:
The utility model is rational in infrastructure simple, and the manufacturing is easy, cost is low.Cable described in the utility model adopts three layers of stop water, makes cable have good water resistance, interference free performance and electrical property; Cable described in the utility model applies in the Automation of Hydropower Station Facilities Construction, can improve the fail safe of automation operating system, instrument, instrument, electronic computer and the automation equipment that also can be widely used in hydraulic structure, large hydraulic engineering, also can be used for the place of the ask for something waterproof such as electric power, metallurgy, petrochemical industry, airport, good application value and wide market prospects are arranged.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of waterproof control cable, comprise cable core, and described cable core is by stranded the forming of three eradication edge cores; Its insulated wire cores is by conductor 1 and is extruded in conductor 1 outer insulating barrier 2, screen 3 and forms.Be provided with packed layer 4 in the gap of cable core, at the cable outermost layer, extrude outer jacket cover 10, be provided with successively the first water blocking layer 5, inner covering 6, the second water blocking layer 7, metal armouring layer 8 and the 3rd water blocking layer 9 between cable core and oversheath.
The utility model provides a kind of waterproof control cable version and implementation method; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
