Abstract
The utility model discloses a high flame-retardant tension shielding control cable, which aims to provide a control cable with high flame-retardant, anti-tearing, high-temperature resistant, and high bending performances, wherein the cable adopts twice cabling symmetrical structure, a first time cabling core is externally coated with a polyester tape binding, a screen layer and a non-woven fabric layer in turn, a second time cabling core is externally coated with a non-woven fabric layer, a glass fiber tape and a silicone rubber sheath, and the filling materials are disposed in the gap between the cores. The cable of the utility model is suitable for the connecting wires among the casting, forging, heat processing, welding and mechanical processing equipment during the production of modernization large-scale steel and iron under the voltage of 450/750V and the environmental temperature of -50 to 180 DEG C, which is mainly used for controlling and monitoring the spaces such as interlock circuit, protection circuit and the like.
Description
Technical field
The utility model relates to a kind of control cable, particularly relates to a kind of high flame retardant tension shielding control cable.
Background technology
At operating voltage 450/750V; during the modernized large-scale iron and steel of environment for use temperature between-50 ℃ to+180 ℃ produced; occasions such as connecting line between casting, forging and pressing, heat treatment, welding and the machining equipment and control, monitoring interlock circuit and protection circuit; for having relatively high expectations of cable, require characteristics such as cable has high flame retardant, anti-tearly draws, high temperature resistant, bending property height.
That Chinese patent discloses is a kind of " high flame retardancy silicon rubber control cable (publication number CN2595321), this utility model relates to a kind of high flame retardancy silicon rubber control cable, is characterized in: the outside of conductor is a perfluoroethylene-propylene insulated with material layer; The outside of insulating barrier is followed successively by packed layer, band and silicon rubber oversheath.The advantage of this cable is the thermal endurance class height, and is simple in structure, and low cost of manufacture, but because this cable does not adopt the stranding symmetrical structure twice, thereby the cable internal structure is inharmonious is when cable bears big pulling force, because that discontinuity easily causes cable core to be drawn is bad; In addition, this cable does not adopt screen, and circuit disturbs more serious, thereby as control cable its weak point is arranged in the large-scale iron and steel production of modernization.
The utility model content
Technical assignment of the present utility model is at above weak point, the high flame retardant tension shielding control cable that provide a kind of high temperature resistant, high flame retardant, anti-tearly draw, bending property is high
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of high flame retardant tension shielding control cable is characterized in that cable has adopted the symmetrical structure of twice stranding; The core of stranding is coated with polyester belt band, screen and nonwoven layer outward successively for the first time; The core of stranding is coated with nonwoven layer, glass fibre belt and silicone rubber jacket outward successively for the second time; In the space of described core, be provided with inserts.
Core comprises that copper wire bundle closes conductor and silicone rubber insulation layer.
Screen adopts the tinned copper wire woven shield.
Silicone rubber jacket adopts the anti-tear silicone rubber jacket that draws of high flame retardant.
Compared with prior art, the utility model has the advantages that:
1, the utility model has adopted the symmetrical structure of twice stranding, makes cable cable internal structure coordinate, stressed being evenly distributed when cable moves, and when cable bore the bigger pulling force of mobile device, cable conductor was difficult for being drawn bad.
2, the utility model is when a stranding, adopt the tinned copper wire braid shielded, prevented between the inside and outside core of when work stranding and the electromagnetic interference between the equipment and instrument, can also prevent that cable screen under abominable operational environment is difficult for oxidized here, in addition, adopt the tinned copper wire braiding to have and allow the advantage of the easier mobile bending of cable as screen.
3, the utility model has adopted the anti-tear silastic material that draws of high flame retardant as sheath, has anticorrosion resistance and high temperature resistance property, can satisfy in the large-scale iron and steel production equipment requirement of abominable operational environment to cable, and the tearing in anti-the moving.
In addition, this cable is stable because of symmetrical configuration, in addition rakish advantage behind the finished product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a high flame retardant tension shielding control cable core structure chart.
Embodiment
With reference to Figure of description high flame retardant tension shielding control cable of the present utility model is done following detailed explanation.
A kind of high flame retardant tension shielding control cable, rated voltage 450/750V adopts the symmetrical structure of twice stranding, and two kinds of different cores are counted the cable of different cross section, and stranding is stranded at twice.The core of stranding has four for the first time, and core is coated with overlapping wrapped polyester belt band 3, tinned copper wire woven shield 4 and overlapping wrapped nonwoven layer 5 outward successively; The core of stranding has ten for the second time, and core is coated with the anti-tear silicone rubber jacket 8 that draws of overlapping wrapped nonwoven layer 5, glass fibre belt 7 and high flame retardant outward successively; In the space of described core, be provided with pp rope inserts 6.
