The cable is formed, from inside to outside successively, by the precision metal wires, insulating layers, U-shaped separating channels, calcium oxide, a cable inner protection layer, a steel band armor layer, and a plastic material layer which can become ceramic in burning. A cross section of each U-shaped channel is in a U-shape, and the U-shaped channel wraps one of the insulating layers and separates two adjacent ones of the insulating layers. Each insulating layer coats one of the precision metal wire cores. The calcium oxide is located between the adjacent precision metal wire cores. The cable inner protection layer is attached to the precision metal wire cores. The steel band armor layer is attached to the cable inner protection layer. The plastic material layer is attached to the steel band armor layer. Each precision metal wire core is formed by stranding main wires, edge gap wires and middle gap wires. The cross section of each main wire is round; the cross section of each middle gap wire is triangular and the middle gap wire is in the gap between three adjacent ones of the main wires; and each edge gap wire is elliptical and is in the gap between two adjacent main wires on the edge.
Description
Technical field
The utility model relates to cable technology field, relates to or rather a kind of cable that precision metallic wire rod and burning can ceramic plastic material that adopts.
Background technology
Cable conduction is to realize by metal material, cable metal material is to be that circular metal wire rod spiral winding is made by many sliver transvers sections, by extrusion die, multiply metal wire rod is extruded distortion, twists cross section processed and be the strand structure processed of the shapes such as fan-shaped, watt shape, circle.Circular metal wire rod strand is built in together, in the middle of adjacent wire rod, can there is space, because space can cause metal wire rod chap, the outer jacket that outside needs and the material usage of steel-tape armouring layer also increase thereupon, cause cable to become heavy and chap, improve cable cost, improved logistics cost, increased difficulty of construction.On the other hand, in the middle of adjacent wire rod, can there is space, also can hinder electric current flowing between adjacent wire, weaken the electric conductivity of metal material.
Edge at cable with metal material, the cross section of metal wire rod is rounded, and edge just there will be the irregularly shaped of fluctuating, and in high-tension environment for use, the projection at edge easily causes point discharge, causes accident.In addition, in cable, the gap of conductor is plastic material, plastic material volume in combustion process can dwindle and powder, and therefore, can make to come in contact and cause short circuit between adjacent conductor, like this, often fire and short circuit become two positive correlation factors in cable fault process, that is to say, fire causes short circuit, short circuit simultaneously causes again fire, and both promote by mutual forward.
As can be seen here, above-mentioned existing cable still has many defects, and is urgently improved.
Because the defect that above-mentioned existing cable exists, the design people is based on being engaged in this type of product design manufacture for many years, amass and have abundant practical experience and professional knowledge, actively research and innovation in addition, to founding a kind of cable that precision metallic wire rod and burning can ceramic plastic material that adopts, can improve the general molding structure of existing cable on the market, make it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcomes the defect that existing cable exists, and improves tightness degree, electric conductivity and the smooth degree of cable, and overcomes fire in existing cable and cause short circuit, short circuit simultaneously to cause again the defect of fire.
The utility model solves its technical problem underlying and realizes by the following technical solutions.A kind ofly adopt the cable that precision metallic wire rod and burning can ceramic plastic material according to what the utility model proposes, from inside to outside successively by precision metallic wire rod inner core, insulating barrier, U-shaped separate slot, calcium oxide, cable sheath, steel-tape armouring layer and can ceramic plastic material layer forming, U-shaped separate slot cross section is U-shaped, be wrapped in outside insulating barrier, adjacent two insulating barriers are separated, insulating barrier parcel precision metallic wire rod inner core, calcium oxide is between adjacent precision metallic wire rod inner core, cable sheath is close to precision metallic wire rod inner core, steel-tape armouring layer is close to cable sheath, can be close to steel-tape armouring layer by ceramic plastic material layer, precision metallic wire rod inner core is made up of strand wire strand system, precision metallic wire rod inner core is by electric main, edge voids electric wire and intermediate gaps electric wire strand system composition, electric main cross section is rounded, intermediate gaps wire cross-section is triangular in shape, intermediate gaps electric wire is positioned at the position, space of adjacent three electric mains, edge voids electric wire ovalize, edge voids electric wire is positioned at the position, space of the electric main of adjacent two edges edge.
Employing precision metallic wire rod described in the utility model and burning can ceramic plastic material cable, the beneficial effect of its generation is: can adopt the burning silastic material of ceramic afterwards by ceramic plastic material layer, can play the effect of isolation flame, U-shaped separate slot two the precision metallic wire rod inner cores that wrapped up by insulating barrier of space between adjacent effectively that use glass fibre to make, in the time of temperature rising or breaking out of fire, can effectively avoid two adjacent cables to be short-circuited, calcium oxide is absorbing after water and carbon dioxide and can harden, play and extend the cable effect of service life, in precision metallic wire rod inner core strand process processed, can there is corresponding deformation in each strand of electric wire, space between each strand material is further reduced, adopt the position, space of adjacent three electric mains of intermediate gaps wire pair to fill, effectively improve the tightness degree of metal material, and then improved the electric conductivity of cable, and adopt the position, space of the electric main of edge voids wire pair adjacent two edges edge to fill, effectively improve the smooth of the edge degree of metal wire rod strand structure processed.
