Abstract
The utility model relates to a structure of the electrical cable used for monitoring data signals. The outer portion of each wire core is packed with a low-smoke and low toxicity insulating layer. The outer portion of a nonoxidation copper wire core is respectively distributed with a shielding layer, an inner protecting layer, a copper armor layer and an outer protecting layer. The shielding layer is made from a nonoxidation copper wire or a copper belt. The utility model can guarantee small distortion on information transmission. The products is provided with the effects of environment protecting and fire resistance. The anti-electromagnetic interference effect and the antistatic interference effect of the electrical cable are greatly improved. Meanwhile, the utility model also has the characteristics of shock resistance, collision resistance and ground pressure resistance and conforms to the requirements of the modern information market.
Description
Technical field
The utility model relates to a kind of structure of measuring and control data signal cable.
Background technology
Along with the investment of construction projects such as skyscraper, subway, tunnel constantly enlarges, requirement to the low-smoke low-halogen of cable and fire resistance is more and more higher, but, defectives such as the measurement and control cable that prior art is used for transmission of data signals exists transmission signals distortion, no anti-flammability, magnetic disturbance is serious, fire protecting performance is poor, the product durability is low are unfavorable for the needs in present information market.
The utility model content
The utility model purpose is to provide a kind of anti-strong jamming measurement and control cable of low smoke, zero halogen low toxicity that can overcome above-mentioned defective.
The utility model adopts the high-quality copper free wire to make conductor, guarantees the effect of information transmission; Use low-smoke low-halogen special cable material as insulating material, make product have environmental protection and fire resistance; Application copper free wire, copper strips are made shielding material, have improved the anti-electromagnetic interference of cable, antistatic interference effect greatly.To underground cabling, for pre-protecting against shock, collision and geostatic pressure, the wrapped armouring of utilization high-quality low-carbon type steel band.The utility model novel structure, rationally cooperates technology, product is reached meet the superior function of present information market demand.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 oxygen-free copper core, 2 low-smoke low-halogen insulating barriers, 3 copper screens, 4 sheaths, 5 armours, 6 outer jackets, 7 inserts.
Specific embodiment
As shown in the figure, outside four isometrical oxygen-free copper cores 1, wrap up low-smoke low-halogen insulating barrier 2 respectively, four oxygen-free copper cores 1 that have an independent insulating barrier 2 and inserts 7 is wrapped in oxygen-free copper stripe or be wrapped in the net of copper free wire braiding, form copper screen 3, wrapped sheath 4 outside copper screen 3, wrapped with the low-carbon type steel band outside sheath 4 again, form armour 5, at last, make outer jacket 6 at outermost layer with Halogen, low cigarette, low toxicity PVC.
