Embodiment
Further illustrate the utility model by specific embodiment below.
As shown in Figure 1, the fire-proof and explosion-proof rubber sleeve flexible cable of a kind of Novel medium voltage, comprise soft copper conductor 1 and the semi-conductive tape 2 that is coated on soft copper conductor outer surface, be coated on the conductor shield 3 on semi-conductive tape 2 surfaces, be coated on the insulating barrier 4 on conductor shield 3 surfaces, be coated on the insulation screen 5 on insulating barrier 4 surfaces, be coated on the metal screen layer 6 outside insulation screen 5, for the filler 7 of longitudinal water-blocking, wrapped in the metal band 8 that becomes cable core surface, extrude in the fireprotection layer 9 on metal band 8 surfaces, be embedded in the single metal wire 10 in explosive-proof jacket, be coated on the explosive-proof jacket 11 on fireprotection layer 9 surfaces.
Described conductor 1 is the stranded flexible conductor forming of stranded copper wire;
Described semi-conductive tape 2 forms for semiconductive nylon tape is wrapped;
Described conductor screen 3 forms for semi-conductive rubber shielding material extrudes;
Described insulation 4 forms for ceramic silicon rubber-covered material extrudes;
Described insulation shielding 5 forms for semi-conductive rubber shielding material extrudes;
Described metallic shield 6 is proof copper-wire braided layer;

Principle explanation:
1, soft copper conductor is for electric energy transmitting.
2, semiconductive nylon tape is used for tightening conductor, and balanced conductor Electric Field Distribution.
3, the Electric Field Distribution of the even conductor of conductor screen.
4, insulation ensures that electric energy transmits in conductor, and can crust under combustion case, and can ensure electrical insulation properties.
5, insulation shielding prevents the gathering of electrostatic charge at insulating surface, causes insulation breakdown.
6, electric charge is imported in time the earth by metal wire shielding, and can absorb certain heat.
7, ceramic silicon rubber filling bar can crust under combustion case, under fire condition, can absorb heat, extends the fireproofing of cable time.
8, the wrapped metal screen layer of copper strips can play the effect that prevents interference.
9, fire prevention oversheath employing ceramic silicon rubber sheath material extrudes and forms, this rubber, under combustion case, can discharge hydrone, itself becomes ceramic-like material, there is certain mechanical strength and electrical insulation properties, can ensure cable structural stability under flame combustion condition.
10, single metal wire can lead ground in time fast by the electric charge of semiconductive oversheath accumulation.
11, semiconductive oversheath can prevent cable surface accumulation electrostatic charge, thereby has prevented the blast causing because of static.
