Description
Technical field
The present invention relates to a kind of electric power cable, relate more specifically to a kind of non-normal safe multi-core electrical cable and manufacture method thereof.
Background technology
Electric wire has been widely used in the detection of industrial production, communications and transportation, architectural engineering and facility, modern agriculture and scientific research, war industry equipment or military installations, space, ocean at present, and has reached ubiquitous state.Along with socioeconomic activity description is carried out the development of step great-jump-forward from the degree of depth to the range, the electric wire kind is brought in constant renewal in and is perfect, and output continues to increase.For example, building the high-intelligentization building needs for hundreds of, thousands of computer network cable that electronic computer divides cascade network to use; Build the public cable television network in city, the whole city and even all banks of the whole nation banking procedure where deposits and withdrawals are processed at any branch bank, carry out online economic interaction and information interchange etc. and must install the broad band cable net that high reliability transport is used; Realize that the emission of military artillery or antiaircraft artillery group remote control procedure need design the control cable that is fit to field extreme environment.
The application of electric wire mainly is divided into three major types: electric power system, the information transmission system and plant equipment and instrument and meter system.The electric wire product that electric power system adopts mainly contains built on stilts bare wire, bus-bar (bus), power cable, rubber cover cable, aerial insulated cable), branch cable (replacing the part bus), electromagnetic wire and power equipment be with the electrical equipment electric wire etc.The electric wire that is used for the information transmission system mainly contains local cable, camera cable, electronic cable, radio frequency cable, fiber optic cable, data cable, electromagnetic wire, power communication or other composite cables etc.In plant equipment, the instrument and meter system except that built on stilts bare wire almost other all products application is all arranged, but mainly be power cable, electromagnetic wire, data cable, instrument and meter cable etc.
The electric wire product mainly is divided into five big classes: bare wire and bare conductor goods, power cable, electrical equipment electric wire, communication cable and optical fiber and electromagnetic wire.Wherein the principal character of power cable outside conductor, squeeze (around) the bag insulating barrier, as aerial insulated cable, or several core stranded (phase line of corresponding electric power system, zero line and ground wire), as the above aerial insulated cable of two cores, or increase restrictive coating again, as plastics/rubber cover electric wire.Main technology has drawing, stranded, insulating exruded (wrapped), stranding, armouring, sheath to extrude etc.
The selection of power cable should be abideed by following principle: the rated voltage of cable is greater than or equals the rated voltage of mounting points electric power system; Cable continues the sustained ceiling current that allowable current should be equal to or greater than the power supply load; The requirement of the stability when the electric power system short circuit will be satisfied in the core cross section; Voltage drop meets the requirement of cable length; The minimum short circuit current of line end should be able to make protective device move reliably.
Yet general cable exists certain defective at present.For example, along with improving constantly of economic and social life, power consumption also increases considerably thereupon, the input voltage that is input to cable so also improves step by step, and therefore, cable heats up rapidly, cause cable can not stand high temperature not broken hair heat burn, thereby influence the realization of whole cable circuit greatly.In addition, when cable is linked into All other routes, the processing of need peeling of cable incoming end, and the outer field material decortication of parcel conductor is difficult unusually in the existing cable.In addition, conductor is generally circle, and the space is arranged between the plurality of conductors of multi-core cable unavoidably, when outside these conductors, squeeze (around) behind the bag insulating barrier, sheath, conductor is extruded and has formed the outward appearance of undaform, has influenced the feel and the aesthetic feeling of cable greatly.
Therefore, be necessary to provide a kind of improved electric power cable and manufacture method thereof to overcome above-mentioned defective.
