Abstract
The invention discloses a waterproof control cable. According to the cable, a polythene insulation layer is extruded on the outer surface of a conductor; a waterproof rope is filled to form the cable, and the formed cable is wrapped by a waterproof tape; a copper wire shielding layer or a copper strip wrapping layer or an aluminum plastic composite tape wrapping layer is arranged outside a wrapping layer; a waterproof tape is wrapped outside the shielding layer; and a polyvinyl chloride (PVC) sheath layer is extruded outside the waterproof tape. The waterproof control cable is reasonable and simple in structure, easy to produce and manufacture, and low in cost. The cable has excellent waterproof performance, interference resistance and electrical property, is used for a cable for automatic facility construction in a hydropower station and has a high popularization and application value and a wide market prospect, and the safety of an automatic operating system can be improved.
Description
Technical field
The present invention relates to the power cable field, specifically be meant a kind of water proof type control cable.
Background technology
According to the national energy development plan, country invests money in developing water power with 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 adopted improves, all by computer control, so requirement must be a waterproof to cable.The general control cable that uses at present adds insulating barrier by conductor and sheath constitutes; Water resistance is poor, interference free performance is not strong; The proof voltage ability also can be affected; Bring certain hidden danger for many equipment operate as normal, cause the generation of some accidents, so need a kind of special control cable of development with water resistance requirement.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned cable exists, provide that a kind of water proofing property ability is good, antijamming capability strong, the good water proof type control cable of proof voltage ability.
A kind of water proof type control cable of the present invention; Comprise cable core; Gap at cable core is provided with packed layer, extrudes the outer jacket cover at the cable outermost layer, and it mainly is: between cable core and oversheath, be provided with first water blocking layer, screen and second water blocking layer successively.
Described cable core is that the insulated core is stranded forms by two; Its insulated wire cores is by conductor and is extruded in the outer insulating barrier of conductor and constitutes.
Described packed layer is a waterproofing rope.
Described screen is copper wire braid or copper strips lapping layer or the rich covering of aluminium-plastic tape.
Described first water blocking layer and second water blocking layer are waterstop.
Described oversheath is the PVC sheath.
Beneficial effect of the present invention is:
The present invention is rational in infrastructure simple, and the manufacturing is easy, cost is low.Cable has excellent waterproof property, interference free performance and electrical property.For the Automation of Hydropower Station Facilities Construction is used cable; 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 ask for something waterproof such as electric power, metallurgy, petrochemical industry, airport, excellent popularization using value and vast market prospect are arranged.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; Outer surface at conductor 1 extrudes polyethylene layer 2; Adding waterproofing rope at the extexine of insulating barrier 2 is that packed layer 3 is filled strandings, with wrapped one-tenth first water blocking layer 4 of waterstop, is screen 5 (screen 5 is copper wire braid or copper strips lapping layer or aluminium-plastic tape lapping layer) in first water blocking layer, 4 outsides behind the stranding; Wrapped again one deck waterstop becomes second water blocking layer 6 outside screen 5, squeezes one deck PVC then and becomes outer jacket 7.With the waterproofing rope and the two-sided waterstop filled cable space of high-quality, can expand rapidly behind the chance water produces fine and close water blocking layer, thereby effectively suppresses spreading of moisture, reaches the purpose that effectively blocks water.
The invention provides a kind of water proof type control cable version and implementation method; The above only is a preferred implementation method of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
