Abstract
A polyethersulfone insulating heat-resistant antiflaming control cable is characterized in that an insulating layer is extruded on a conductor twisted by one or a plurality of tin plated coppers so asto form insulated conductor cores; a plurality of insulated conductor cores are twisted to form a cable so as to form a cable conductor; heat-resistant materials can be filled in the cable conductorso as to form a filling layer, and on the external surface of the filler layer, the following steps are conducted sequentially: lapping a band layer, longitudinally lapping a shielding layer and extruding a sheath layer; a lapping layer takes antiflaming heat-resistant glassfibic clothes as materials; the insulating layer and the sheath layer both adopt polyethersulfone PES extruding materials; the shielding layer is lapped longitudinally by soft copper tapes; and drainage threads which are formed by the plurality of tin plated coppers are arranged between the lapping layer and the shielding layer. The polyethersulfone insulating heat-resistant antiflaming control cable is heat resistant, vapor resistant, antiflaming, acid and alkali chemical agent resistant, and environment-friendly, andhas excellent electrical performance and mechanical performance.
Description
Technical field
The utility model relates to a kind of electrical equipment control cable, relates in particular to a kind of heat-resistant fireproof control cable, belongs to technical field of electric wires and cables.
Background technology
At present, the kind of the heat-resistant fireproof control cable on the market is a lot, and its performance is determined by the material behavior of its insulating material and restrictive coating that mainly material heatproof rank has determined the heatproof degree of cable.At present commonly used have cross-linking radiation polyolefin, silicon rubber, fluororesin, polyimides, a magnesium oxide etc.Along with The development in society and economy, the high temperature-resistant cable that all trades and professions are used is more and more, wilderness demand high temperature-resistant cables such as Aero-Space, rolling stock, the energy, iron and steel, non-ferrous metal metallurgy, oil exploitation, motor for example, most occasions require more and more higher for the combination properties such as fire-retardant, high temperature resistant, environmental protection, electric property and mechanical performance of control cable, but existing cable product can not satisfy this requirement well.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of have excellent heat resistance, physical and mechanical properties, electrical insulation capability, extrusion molding are provided, particularly have can at high temperature use continuously with temperature environment jumpy in still keep the polyether sulfone insulation heat-resistant fireproof control cable of stable performance.
The utility model adopts following technical scheme:
The design feature of polyether sulfone insulation heat-resistant fireproof control cable is that the extruded insulation layer constitutes insulated wire cores on single or many stranded tin-coated copper conductors, constitutes cable core by the stranded stranding of many eradications edge core; In cable core, can suitably fill exotic material and form packed layer, and at the wrapped successively belting layer of the outer surface of packed layer, vertical bag screen with extrude restrictive coating; Described lapping layer is to be material with flame-resistant high-temperature-resistant glass cloth, and described insulating barrier and external sheath layer all adopt polyether sulfone PES to extrude material; Described screen is the vertical bag of soft copper band screen, and places the drainage thread that many tinned copper wires constitute between lapping layer and screen.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the beneficial effects of the utility model are, structural design is simple, scientific and reasonable, manufacture easily, and cable insulation and oversheath adopt polyether sulfone PES, have effectively improved the serviceability of product.Cable has excellent heat resistance, physical and mechanical properties, electrical insulation capability, extrusion molding, particularly have can at high temperature use continuously with temperature environment jumpy in still keep outstanding advantages such as stable performance:
A, heat distortion temperature are at 200-220 ℃, and serviceability temperature is 180-200 ℃ continuously, and Undterwriter's Laboratory temperature index is 180 ℃;
B, can anti-150-160 ℃ hot water or steam, the at high temperature erosion of acid and alkali, alkali;
C, modulus of elasticity-the 100-200 degree is almost constant, and is particularly all good than any thermoplastic resin more than 100 degree;
D, coefficient of linear expansion are little, and its temperature dependency is also little;
E, have avirulence, approved, also meet the requirement of No. the 434th, Japanese health ministry and No. 178 bulletins by U.S. FDA;
F, have self-extinguishment, not adding any fire retardant promptly has excellent flame retardancy, can reach the UL94V-0 level.
2, the screen in the utility model adopts the vertical bag of copper strips and adds drainage thread, makes cable shield effective, if adopt embossing technology then to make whole cable more soft.
Description of drawings
Fig. 1 the utility model four-core polyether sulfone insulation heat-resistant fireproof control cable structural representation.
Number in the figure: 1 conductor, 2 insulating barriers, 3 packed layers, 4 lapping layers, 5 drainage threads, 6 screens, 7 oversheaths.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, present embodiment is that extruded insulation layer 2 constitutes insulated wire cores on single or many stranded tin-coated copper conductors 1, constitutes cable core by the stranded stranding of many eradications edge core; In cable core, can suitably fill exotic material and form packed layer 3, and at the wrapped successively belting layer 4 of the outer surface of packed layer 3, vertical bag screen 6 with extrude restrictive coating 7;
In concrete the enforcement, lapping layer 4 is to be material with flame-resistant high-temperature-resistant glass cloth, and insulating barrier 2 and external sheath layer 7 all adopt polyether sulfone PES to extrude material; Screen 6 is the vertical bag of the soft copper band screen of 0.1mm, adopts embossing technology, and place the drainage thread 5 that many tinned copper wires constitute between lapping layer 4 and screen 6.
