Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of waterproof fireproofing multi-core controlled cable described in the utility model, including cable core, gap location at cable core is provided with Tarpauling packed layer 10, being sequentially provided with chlorosulfonated polyethylene inner sheath the 11, the 3rd ethylene propylene diene rubber insulating barrier 12, fireproof coating layer 13 and calcining Mica tape layer 14 outside cable core, the outermost layer at cable core extrudes chlorosulfonated polyethylene oversheath 15 again；Described cable core is made up of 5, master core of rectangular support frame and four control conductor；Wherein, the center of rectangular support frame is provided with circular hole 51, and four limits are respectively equipped with the semi-circular recesses 52 of the identical indent of size；What described master core was corresponding is placed in circular hole 51, and four control conductor are placed in four semi-circular recesses 52 so that the construction of cable is compact stable, and the resistance to ability of drawing of resistance to compression is strong；Described master core is made up of three stranded rear braiding antitorque cylinders of copper wire 4 of main single lines；Wherein, the first ethylene propylene diene rubber insulating barrier 2 that described main single line by leading body 1, is extruded in outside leading body 1 and be arranged on buckle type lock armo layer 3 in the stainless steel band outside the first ethylene propylene diene rubber insulating barrier 2 and constitute；Control conductor by central elastic rod 6 and the control single line that is arranged in outside flexible rod 6 stranded after be surrounded by Tarpauling lapping layer 9 and constitute；Wherein, the described single line that controls is by controlling conductor 7 and being extruded in the second ethylene propylene diene rubber insulating barrier 8 controlled outside conductor 7 and constitute.
The external diameter size of described master core is identical with the internal diameter size of circular hole, it is ensured that master core is difficult drop-off in circular hole；The external diameter of described control conductor is less than the internal diameter of semi-circular recesses.
Principle of the present utility model is:
This utility model employs hollow rectangle bracing frame, on four limits, have semi-circular recesses again, master core is placed on the inside of hollow rectangle bracing frame, in four control conductor are placed on four semi-circular recesses of hollow rectangle skeleton, constitute cable core, compact conformation is stable, and the resistance to ability of drawing of resistance to compression is strong；Cable the most all have employed ethylene propylene diene rubber insulating barrier, and wherein, ethylene propylene diene rubber has characteristics that 1) low-density high fillibility: ethylene propylene diene rubber is the rubber that a kind of density is relatively low, and its density is 0.87；In addition can be the most oil-filled and add filler, thus the cost of rubber can be reduced, compensate for the shortcoming that ethylene propylene diene rubber rubber price is high, and for the ethylene propylene diene rubber of high Mooney, high fill after physical and mechanical properties to reduce amplitude little；2) resistance to ag(e)ing: EP rubbers has the resistance to weather of excellence, resistance to ozone, heat-resisting, acid and alkali-resistance, resistance to water vapour, colour stability, electrical property, oil-filled property and room temperature mobility；Ethylene propylene diene rubber goods at 120 DEG C can life-time service, 150～200。Can of short duration or interval use under C；Add suitable age resistor and can improve its use temperature；Can use under more exacting terms with the ethylene propylene diene rubber of peroxide crosslinking；Ethylene propylene diene rubber at ozone concentration 50 × 10～, stretch 30%, do not chap up to 150 more than h；3)
Corrosion resistance: owing to EP rubbers lacks polarity, degree of unsaturation is low, thus various polar chemical product such as alcohol, acid, alkali, oxidant, cold-producing medium, detergent, vegetable and animals oils, ketone and fat etc. are all had preferable resistance;But belong to and virtue belongs to solvent (less stable in such as gasoline, benzene etc. and mineral oil at fat；4 resistance to steam: EP rubbers has the water-fast steam performance of excellence and is better than its thermostability；In 230 DEG C of superheated steams, after nearly 100 h, outward appearance is unchanged；And fluorubber, silicone rubber, fluorosioloxane rubber, butyl rubber, nitrile rubber, natural rubber are under similarity condition, there is obvious degradation phenomena in experience short period outward appearance；5) resistance to superheated water performance: ethylene propylene diene rubber resistance to superheated water performance is also preferable, but closely related with curing system used；With dithio two morpholine, the TMTD EP rubbers as curing system, after soaking 15 months in 125 DEG C of superheated waters, mechanical property change is the least, cubical expansivity only 0.3%；6) electrical property: ethylene propylene diene rubber has electrical insulation capability and the corona resistance of excellence, and electrical property is better than or close to butadiene-styrene rubber, chlorosulfonated polyethylene, polyethylene and crosslinked polyethylene；7) elastic: nonpolarity substituent group in ethylene propylene diene rubber molecular structure, intramolecular cumulative is low, and strand can keep compliance in relative broad range, is only second to natural rubber and butadiene rubber, and remains at low temperatures keep.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement, these improvement also should be regarded as protection domain of the present utility model.
