Description

There is shielding and chemical-resistant resistance function calculating electric cable
Technical field
The utility model relates to cable technology field, relates in particular to one and has shielding and chemical-resistant resistance function calculating electric cable.
Background technology
Cable is normally by the electric wire of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.At oil plant, petrochemical plant and often contact the places such as the defeated modified line road, electrical control, monitoring circuit of aromatic solvent and need to use a large amount of cables, and existing cable is poor aspect fire-retardant, chemical resistance, as manufacturing cost is too high to have chemicals-resistant corrosion function.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes one and there is shielding and chemical-resistant resistance function calculating electric cable, there is advantages of good shielding performance, chemical resistance corrosion, fire resistance, and cost is low.
The one the utility model proposes has shielding and chemical-resistant resistance function calculating electric cable, comprising:
At least one copper conductor bundle;
Insulating barrier, is coated on the outside of described copper conductor bundle;
Lapping layer, overlapping wrapped being twisted into outside right described insulating barrier core;
Screen, is coated on outside described lapping layer;
Total lapping layer, is coated on outside described screen, and fills and make cable core circular, and described total lapping layer from outside by shielded pair being strapped in together tightly;
Inner sheath, is coated on the outside of described total lapping layer;
Aluminum plastic composite belt longitudinal covering, be coated on the outside of described inner sheath and in drag a tinned copper wire drainage thread;
Oversheath, is coated on the outside of described aluminum plastic composite belt longitudinal covering.
Preferably, described copper conductor bundle is that multiply soft copper skein silk closes and forms, and being combined between described copper conductor bundle is regular stranded.
Preferably, described insulating barrier is flexible PVC insulating barrier.
Preferably, described screen is proof copper-wire braided screen.
Preferably, described inner sheath is polyvinyl chloride inner sheath.
Preferably, described oversheath is flame-proof polyethylene oversheath.
In the utility model, screen prevents the interference between cable pair, aluminium strip bonding flame-proof polyethylene sheath makes cable have resistance to chemical reagents and suppresses medicine penetrability, in aluminum plastic composite belt longitudinal packet form, tow streamline and can guarantee that cable has combined shielding effect, inner drainage thread is conducive to cable and does grounding.Therefore, there is not melting of cable in the situation that of burning, do not drip, not flame-retarding power energy, and cost is lower, finds broad application in can and often contacting the project such as signal transmission, monitoring circuit of aromatic solvent at high request, high-level oil plant, petrochemical plant.
Accompanying drawing explanation
Fig. 1 is a kind of profile with shielding and chemical-resistant resistance function calculating electric cable the utility model proposes.
Reference numeral:
1, copper conductor bundle; 2, flexible PVC insulating barrier; 3, lapping layer; 4, proof copper-wire braided screen; 5, fill; 6, total lapping layer; 7, polyvinyl chloride inner sheath; 8, aluminum plastic composite belt longitudinal covering; 9, zinc-plated drainage thread; 10, flame-proof polyethylene sheath.
Embodiment
As shown in Figure 1, Fig. 1 is that the one the utility model proposes has shielding and chemical-resistant resistance function calculating electric cable profile.
With reference to Fig. 1, the utility model embodiment provides one to have shielding and chemical-resistant resistance function calculating electric cable, comprise: at least one copper conductor bundle 1, described copper conductor bundle 1 is that multiply soft copper skein silk closes and forms, being combined between copper conductor bundle 1 is regular stranded, and be also the most stable layout type, external force is difficult to change the combination layout between it.Flexible PVC insulating barrier 2, is coated on the outside of described copper conductor bundle 1, can guarantee the not short circuit of mutually insulated between sub-thread copper conductor bundle 1.Lapping layer 3, the overlapping wrapped right insulated wire cores that is twisted into.Proof copper-wire braided screen 4, is coated on outside described lapping layer.Total lapping layer 6, is coated on outside proof copper-wire braided screen 4, and fills 5 and make cable core circular, described total lapping layer 6 can be from outside by shielded pair being strapped in together tightly, structure, the stable of insulated wire cores processed.Polyvinyl chloride inner sheath 7, be coated on the outside of described total lapping layer 6, the outer employing aluminum plastic composite belt longitudinal of described inner sheath 7 covering 8 and in drag a tinned copper wire drainage thread 9, the effect of shielding external electromagnetic waves is played in this design, and can prevent the corrosion of outside chemical product and prevent that chemicals from penetrating sheath corrosion internal core.Flame-proof polyethylene oversheath 10, is coated on the outside of aluminum plastic composite belt longitudinal covering 9, makes cable have fire resistance, and the function that has fine shielding and chemical resistance corrosion and penetrate.
In the utility model, screen prevents the interference between cable pair, aluminium strip bonding flame-proof polyethylene sheath makes cable have resistance to chemical reagents and suppresses medicine penetrability, in aluminum plastic composite belt longitudinal packet form, tow streamline and can guarantee that cable has combined shielding effect, inner drainage thread is conducive to cable and does grounding.Therefore, there is not melting of cable in the situation that of burning, do not drip, not flame-retarding power energy, and cost is lower, finds broad application in can and often contacting the project such as signal transmission, monitoring circuit of aromatic solvent at high request, high-level oil plant, petrochemical plant.
The utility model embodiment provide the above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection range of the present utility model.
