Description
Technical field
This utility model relates to field of cable technology, particularly relates to a kind of control cable with waterproof interference free performance.
Background technology
Control cable and be mainly used in the occasions such as below ac rated voltage 450V/750V control, monitoring loop and protection circuit.Railway signal cable, railway digital cable, cable capable of shielding digital signals in railways, fire resistant railway traffic signal cable, transponder numerical control transmission cable are the control cables being widely used in the occasions such as high ferro, light rail and subway, specific use environment and high reliability request so that this kind control cable should possess highly reliable waterproof, moisture resistance and high anti-interfering performance.
Railway signal cable, railway digital cable, cable capable of shielding digital signals in railways, fire resistant railway traffic signal cable, transponder numerical control transmission cable mainly has two kinds of basic structures, one class is the cable of composite sheath structure, another kind of is aluminium sheath structural cable, although these control cable has certain water-proof function, but the waterproof and dampproof performance of this kind control cable mainly depends on cable cover(ing), and in actual applications, the control cable being especially chronically in groundwater erosion and wet environment, the season cracking of cable all can cause water or aqueous vapor to penetrate into inside cable, easily cause cable electrical hydraulic performance decline, conductor is progressively aoxidized, insulating barrier is breakdown, have a strong impact on the reliable of control signal, accurate delivery, greatly reduce safety in utilization and the service life controlling cable.Though the protective metal shell in the most this kind of cable has certain shield effectiveness; but the Main Function of sheath is still protection cable conductor; therefore the shielding action of such cable is more weak; lack the reliable shielding action of the physical parameter such as signal and mixed and disorderly electromagnetic wave to external world; even if a least interference signal or electromagnetic interference source all may affect the safe and reliable transmission of control signal; especially to having the occasion of high reliability, high security for high ferro and urban light rail etc., with greater need for a kind of can the control cable of effectively moistureproof and waterproof, high noise immunity.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of has that block-water effect is good, the waterproof anti-interference control cable of strong interference immunity.
In order to solve above-mentioned technical problem, waterproof anti-interference control cable of the present utility model, this cable conductor is blocked water insulation core wire by four and the packed layer that blocks water is constituted, described four insulation core wires that block water are embedded in and block water in packed layer, described in block water insulation core wire conductor on be coated with insulating barrier, screen layer and insulation water blocking layer the most successively；Being surrounded with, on described cable core, the belting layer that blocks water, be extruded with inner liner on this blocks water belting layer, vertical on inner liner be surrounded by steel and mould vertical covering, steel is moulded and is extruded with outer jacket on vertical covering, and this outer jacket is coated with water-repellent layer.
After using said structure, block water in packed layer owing to the insulation core wire that blocks water is embedded in, the inserts that blocks water is filled in the gap between insulation core wire, the inserts that blocks water is good with the compatibility of insulation core wire, fill colloidal stability good and highly water repellant, good airproof performance, waterproof ability is strong, make cable have the water repelling property of excellence, and the insulating properties of cable can be strengthened.Again owing to being provided with screen layer on every insulation core wire, this screen layer effectively intercepts the interference to controlling cable of external electromagnetic field and the signal of telecommunication, it is achieved the safe and reliable transmission of control signal；Being coated on steel on cable core to mould vertical covering and have shielding action equally, therefore screen layer and steel are moulded vertical covering and are constituted the construction of cable with multiple tracks shielding action, so that the shielding action of cable is strengthened, make cable have extremely reliable interference free performance.Respectively with the wrapped insulation water blocking layer of waterstop and the belting layer that blocks water on insulation core wire and on cable core, define double damp-proof structure, the waterproof block-water effect that greatly strengthen.It is surrounded by steel moulds vertical covering due also to vertical on the inner liner of cable; both reliable water-blocking moistureproof structure had been defined; the mechanical protection such as tension, resistance to compression is provided again to cable; extend the service life of cable; not only make cable have the aspect performances such as waterproof, chemically, and mechanical damage and wild animals and plants infringement can be prevented.Inner liner and outer jacket outside cable conductor also make the waterproof and dampproof performance of cable become tighter.On protective coverings of cable, the water-repellent layer of coating, forms again the first road waterproof construction of cable.Therefore this control cable forms the multiple shielding construction of multiple tracks and stop water, has the anti-interference of fabulous waterproof effect and enhancing.
Preferred implementation of the present utility model, described steel moulds vertical covering and indulged bag by composite steel-plastic belt and form, α=15 °, side lap angle of composite steel-plastic belt～20 °, is provided with overlap joint adhesive linkage at the side lap of composite steel-plastic belt.Described overlap joint adhesive linkage is the adhesive layer or weld layer arranged longitudinally along the cable.The preferably side lap structure of composite steel-plastic belt had both ensured the antiseepage function of cable, and vertical packaging material moulded by the most unlikely waste steel.And at the overlap joint adhesive linkage of lap-joint, efficiently solve the seepage problem at the side lap of composite steel-plastic belt, make steel mould vertical covering and form tight closing space, effectively stop the infiltration of water.
The further embodiment that this enforcement is novel, described screen layer is formed by tinned copper wire braiding.Woven shield shield effectiveness is good, and can keep the flexibility that cable is good.
This utility model further embodiment, described insulation water blocking layer is formed by the waterstop that insulate is wrapped, and this wrapped Duplication of insulation waterstop is 25%～35%.The described belting layer that blocks water is formed by semi-conducting water-resistant tape, and this semiconductive wrapped Duplication that blocks water is 25%～35%.This structure water preventing ability is good.
Further embodiment of the present utility model, described inner liner is extruded by high-density polyethylene material and forms.Described outer jacket is extruded by high-density polyethylene material and forms.High-density polyethylene material chemical resistance is good, and abrasion resistance properties is excellent, and tensile strength is good.
Further embodiment of the present utility model, described in block water packed layer by petroleum jelly fill form.Application petroleum jelly inserts has moistureproof and the dual function of insulation, heat stability and water-resistance are excellent.
