Abstract
The utility model discloses a nuclear explosion resistant electromagnetic pulse control cable, which comprises a cable core formed by 5-100 insulated conductor cores. A first shield layer, a second shield layer, a third shield layer, a fourth shield layer, a fifth shield layer and an outer sheath are sequentially arranged outside the cable cores. The nuclear explosion resistant electromagnetic pulse control cable is characterized in that the first shield layer, the third shield layer and the fifth shield layer are respectively lapping-clad copper film strip shield layers; the second shield layer is a lapping-clad aluminum plastic film strip shield layer; and the fourth shield layer is a knitted nickel-plating copper wire shield layer. In the frequency range of 1-100MHz, the shield attenuation can be improved to be not less than 70dB from not less than 60dB; and in addition, the cable has the advantages of favorable bending resistance, high strength, cold resistance, wear resistance and favorable flame-retardant performance and is suitable for being used for fixing or used in a field moving environment.
Description
Technical field
The utility model relates to cable, a kind of anti-nuclear blast electromagnetic pulse control cable of more specifically saying so.
Background technology
Anti-nuclear blast Electro-Magnetic pulse Shielding technology is applied to cable, be to be absorbed electromagnetic energy below safety line with the control core of electric system electromagnetic pulse-resisting screen inside of cable under the impact of nuclear blast electromagnetic pulse strong-electromagnetic field of cable logotype for guaranteeing, more little safe more.Below safety line, just require the minimum shielding attenuation that should reach of shielding properties to be not less than 60dB, could guarantee electric system safety and normal operation like this.But this class cables manufacturing technology is higher, and shielding properties requires high, and the cable flexibility requires, and the shielding construction design difficulty is big.
Present existing electromagnetic pulse-resisting control cable is to set gradually first screen, secondary shielding layer, the 3rd screen, the 4th screen and oversheath outside cable core.Wherein first screen is the aluminum plastic film band screen of wrapped coating, and secondary shielding layer and the 4th screen are the braiding copper wire screen of count 85%, and the 3rd screen is a nickel-base alloy band screen, and oversheath adopts the flexible PVC oversheath.The deficiency that this version exists is: secondary shielding layer and the 4th screen are the copper wire braiding structure, and the copper wire woven shield is because the less hole shield effectiveness that exists of density is relatively poor, and shielding properties is lower, and the double braid layer thickness is big, cable weight is big; The 3rd screen is the nickel-base alloy band structure, the nickel-base alloy band is thicker, hardness is big, the cable flexibility is poor, bending property is relatively poor, and it is often crooked in the cable use, make nickel-base alloy take up the wrinkle hardening, nickel-base alloy belt edge gauffer forms cusp, very easily punctures cable insulation, cause the accident, security reliability is poor; Oversheath is material with the flexible PVC, and intensity is little, wear no resistance, and cold resistance is poor, is unfavorable for dragging use in the holder of low temperature environment and adverse circumstances.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of electromagnetic pulse-resisting performance better, flexibility is good, high strength, resistance to wear is good, resistance to low temperature is high anti-nuclear blast electromagnetic pulse control cable, has the electric system of specific (special) requirements to use to satisfy antagonism nuclear blast electromagnetic pulse strong-electromagnetic field.
The utility model technical solution problem adopts following technical scheme:
The anti-nuclear blast electromagnetic pulse of the utility model cable, it comprises that 5～100 thoroughly do away with the cable core that the edge core constitutes, outside at described cable core, set gradually first screen, secondary shielding layer, the 3rd screen, the 4th screen, the 5th screen and oversheath from inside to outside, described insulated wire cores is the appearance coated insulation layer formation at the multifibres stranded conductor;
Design feature of the present utility model is:
Described first screen, the 3rd screen and the 5th screen are the copper film band screen of wrapped coating;
The aluminum plastic film band screen that described secondary shielding layer is wrapped coating;
Described the 4th screen is braided nickel-plated copper wire screen;
The thickness of described first screen, the 3rd screen and the 5th screen is 0.05～0.10mm;
The thickness of described secondary shielding layer is 0.10mm;
The count of described the 4th screen is not less than 90%;
Described oversheath is to be material with inferior light polyurethane elastomer.
This prior art is compared, and the utility model beneficial effect is embodied in:
The utility model electromagnetic pulse-resisting performance is better, intensity is high, resistance to wear good, flexibility is good, good flame resistance, the fixing or mobile use of resistance to low temperature height, suitable environment condition broad, can satisfy the electric system instructions for use that antagonism nuclear blast electromagnetic pulse strong-electromagnetic field has specific (special) requirements.
The utility model is compared with existing product with the cable embodiment of one 22 core, and the shielding attenuation of anti-nuclear electromagnetic pulse performance is brought up to and is not less than 70dB by being not less than 60dB, and its electromagnetic pulse-resisting performance shielding attenuation multiple has improved 3 times; The resistance to low temperature of cable is brought up to-40 ℃ by-20 ℃.

Embodiment
Present embodiment is to thoroughly do away with the cable core that the edge core constitutes with 22, cable core structure is by existing conventionally form setting, the portion that locates at cable core, set gradually first screen 3, secondary shielding layer 4, the 3rd screen 5, the 4th screen 6, the 5th screen 7 and oversheath 8 from inside to outside, insulated wire cores is appearance coated insulation layer 2 formation at multifibres stranded conductor 1;
In the present embodiment: first screen 3, the 3rd screen 5 and the 5th screen 7 are the copper film band screen of wrapped coating, and thickness is 0.05～0.10mm; Secondary shielding layer 4 is the aluminum plastic film band screen of wrapped coating, and thickness is 0.10mm; The 4th screen 6 is braided nickel-plated copper wire screen, and count is not less than 90%; Oversheath 8 is to be material with cold-resistant, softness, high strength, high-wearing feature, coefficient of friction is low, anti-flammability is high inferior light polyurethane elastomer.
Present embodiment is first screen 3, secondary shielding layer 4, the 3rd screen 5, the 4th screen 6 and the 5th screen 7 are formed comprehensive shielded, the shielding material difference of shielding adjacent layer, the impedance difference, interface paired pulses electromagnetic field between the adjacent layer shielding can produce stronger reflex, a part is subjected to the reflection of comprehensive shielded layer and resists, the energy part of pulse electromagnetic field is by the comprehensive shielded layer heat release that is absorbed into, have only remaining minimum part to see through comprehensive shielded layer and disturb the inner insulated wire cores of comprehensive shielded layer, reached desired shielding properties; Cold-resistant elastomer oversheath flexibility is good, and the intensity height, resistance to wear is good, cold resistance is good, and cable has electromagnetic pulse-resisting performance height, flexibility is good, resistance to wear is good, and lower temperature resistance is good, and is safe and reliable, open-airly moves advantages such as easy to use.
