Description

A kind of isolated form composite cable for environmental protection equipment
Technical field
The present invention relates to field of cables, more particularly to a kind of isolated form composite cable for environmental protection equipment.
Background technology
Cable is the conveying energy, transmits the indispensable basic equipment of information institute, from social informatization, electrified quick Today of development, electric wire have become one of most important basic product in economic construction.Wires and cables industry is mating again Industry, product must satisfy requirement of each main industry of national economy to electric wire performance, and national economy feels most industries all Related to electric wire, industrial status is highly important.The communication cable of data is transmitted, is to pay much attention to communication quality , and come from external electromagnetic interference, it is easy to error in data is caused, the shielded layer of common cable uses tinsel more The problem of establishment, cable shield is susceptible to exoperidium bulge or pierces through core.
Existing composite cable is poor there are shield effectiveness, and dampproof effect is poor, bad mechanical property, oversheath are not wear-resisting lacks Point.
Invention content
It is an object of the invention to:In order to solve the bad shield effectiveness of common composite rope, bad mechanical property and moisture-proof effect The problem of fruit is poor, a kind of isolation effect of present invention offer is good, the fire resisting isolated form composite cable for environmental protection equipment.
The present invention specifically uses following technical scheme to achieve these goals:
A kind of isolated form composite cable for environmental protection equipment including 4 cores, wraps up successively outside 4 cores Non-woven fabrics lapping layer, braiding enhancement layer, damp-proof layer, copper strip shielding layer, separation layer and aluminium wire armoured layer and wearing layer, non-woven fabrics Filled with polypropylene net band, wearing layer includes internal rubber layer and is set in rubber layer outer bottom for gap in lapping layer Half arc strengthens wearing layer, and the material of separation layer is inorganic mineral insulation layer.
Further, the copper strip shielding layer includes the copper foil layer that thickness is 1.2um, and thickness is coated on copper foil layer as 11um Aluminium foil layer, be provided through the through-hole of copper foil layer and aluminium foil layer on copper strip shielding layer, the through-hole into array distribution, Kong Jian Away from for 185-260um, through-hole diameter 15-160um.
Further, the gap inside non-woven fabrics lapping layer is provided with mechanical strengthening core, and core is led including galvanized copper Body and conductor shield, insulating layer, insulation screen and the rubber insulation being successively set on outside zinc-plated copper conductor.
Further, the material of the separation layer is magnesia.
Further, the mechanical strengthening core is worked out by the zinc-coated wire of a diameter of 0.21~0.3mm.
Further, the wearing layer is the fire-resisting ceramic silicone rubber that thickness is 1.3~4.6mm.
Beneficial effects of the present invention are as follows:
1st, mechanism of the present invention is simple, multiple shield, and shield effectiveness is good, and the material of separation layer is magnesia, expects magnesia Fusing point is 2800 DEG C, therefore this kind of composite cable can continue to keep power supply under the fire condition close to the fusing point of copper, be one The fireproof cable of kind truly, Ceramic silicon rubber form hard Ceramic flower and protect under 500 to 700 degree flames Sheath plays isolation burning things which may cause a fire disaster, fireproofing function, but still maintains the characteristic of silicon rubber at normal temperatures.
2nd, external shielding layer includes the copper foil layer that thickness is 1.2um, and the aluminium foil layer that thickness is 11um, shielding are coated on copper foil layer Be provided through the through-hole of copper foil layer and aluminium foil layer on layer, the through-hole into array distribution, pitch of holes 185-260um leads to Bore dia is 15-160um, and this structure of shielded layer can ensure shielded layer under identical thickness, using this structure than passing The list of system more saves copper material using layers of copper structure, has saved cost, and on the other hand, aluminium foil quality is lighter, so as to also reduce screen The weight of layer is covered, shielded layer is evenly equipped with through-hole, outsourcing occurs when working out cable shield this configuration avoids tinsel is used Skin bulge or the problem of pierce through core.
3rd, strengthening core is worked out by the zinc-coated wire of 0.21~0.3mm, and increasing cable increases the machinery of cable by force Degree, can bear mechanical tensile forces, while improve erosion prevention.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
In order to which those skilled in the art are better understood from the present invention, below in conjunction with the accompanying drawings with following embodiment to the present invention It is described in further detail.
Embodiment 1
The present embodiment provides a kind of isolated form composite cables for environmental protection equipment as shown in Figure 1, which is characterized in that including Non-woven fabrics lapping layer 3, braiding enhancement layer 4, damp-proof layer 5, copper strip shielding are wrapped in outside 4 core Isosorbide-5-Nitrae cores 1 successively Layer 6, separation layer 7 and aluminium wire armoured layer 8 and wearing layer 9, the gap in non-woven fabrics lapping layer 2 are resistance to filled with polypropylene net band 9 Mill layer 9 includes internal rubber layer 9-1 and is set in the half arc reinforcement wearing layer 9-2 of rubber layer 9-1 outer bottoms, separation layer 7 Material be inorganic mineral insulation layer.
The material of the separation layer 7 is magnesia.
In the present embodiment, multiple shield, shield effectiveness is good, and the material of separation layer is magnesia, and expecting the fusing point of magnesia is 2800 DEG C, therefore this kind of composite cable can continue to keep power supply under the fire condition close to the fusing point of copper, be a kind of real Fireproof cable in meaning, Ceramic silicon rubber form hard Ceramic flower protective layer, rise under 500 to 700 degree flames To isolation burning things which may cause a fire disaster, fireproofing function, but the characteristic of silicon rubber is still maintained at normal temperatures.
