Abstract
The utility model relates to a flame-retardant and high temperature resistant PEI (polyetherimide) control cable, which is characterized in that an insulating layer is extruded and enwrapped on a conductor stranded by one tinned copper conductor or a plurality of tinned copper conductors to form an insulated wire core; the cable is formed by stranding a plurality of insulated wire cores to form a cable core; high temperature resistant materials can be properly filled in the cable core to form a filling layer; a belt enwrapping layer, a shielding layer and an extruding and enwrapping sheath layer are enwrapped on the outer surface of the filling layer in sequence; the enwrapping layer is made of flame-retardant and high temperature resistant glass fiber cloth; the insulating layer and the outer sheath layer are made of PEI (polyetherimide) extruding and enwrapping materials; the shielding layer is formed by embossing and longitudinally enwrapping a flexible copper belt; and a plurality of leading wires made of tinned copper wires are placed between the enwrapping layer and the shielding layer. The utility model has the advantages of high temperature resistance, radiation resistance, flame retardance, low fume, chemical agent resistance, environmental protection, and excellent electrical and mechanical properties.
Description
Technical field
The utility model relates to a kind of electrical equipment control cable, relates in particular to a kind of flame-resistant high-temperature-resistant control cable, belongs to technical field of electric wires and cables.
Background technology
At present, the kind of the flame-resistant high-temperature-resistant control cable on the market is a lot, and version is varied, generally all is made of conductor, insulating barrier, lapping layer and external sheath layer.Its performance of high temperature-resistant cable 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.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 for example generating, petrochemical industry, metallurgy, motor, 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, and a kind of PEI flame-resistant high-temperature-resistant control cable that has high temperature resistant, radiation hardness, fire-retardant, low cigarette, chemical-resistant reagent, environment-friendly type, has superior electrical performance and mechanical performance is provided.
The utility model adopts following technical scheme:
The design feature of the utility model PEI flame-resistant high-temperature-resistant 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, 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 Polyetherimide PEI to extrude material; Described screen is the vertical bag of a soft copper band embossing 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 utility model is simple in structure, the manufacturing is easy, and cable insulation and oversheath adopt Polyetherimide PEI, has effectively improved the serviceability of product.Polyetherimide PEI is to be the repetition of unit with fragrant acid imide and aryl oxide, its high strength at high temperature is that the acid imide unit by rigidity provides, ehter bond provides the chain flexibility simultaneously, make it that good melt processability and flowability be arranged, by Polyetherimide PEI material property is analyzed, this material has following premium properties:
Good electric property and mechanical performance satisfy the requirement of low-voltage cable fully;
Good radiation resistance, radiation hardness dosage are 4000kGy, far above the needed 850kGy of nuclear power station;
Good flame retardancy, oxygen index reaches 48, far above common fire proofing;
Have good low smoke density, environmental-protecting performance satisfies the European Union environmental protection command request fully;
Has the favorable chemical resistance energy, chemical substances such as ability mineral oil, soda acid, ozone;
Have resistance to elevated temperatures, the nominal operation temperature reaches 130 ℃～150 ℃.
2, the screen in the utility model adopts the vertical bag of embossing copper strips and adds drainage thread, makes cable shield effective, and makes whole cable more soft.
Description of drawings
Fig. 1 is the utility model four-core PEI flame-resistant high-temperature-resistant 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, 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, 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 Polyetherimide PEI to extrude material; Screen 6 is the vertical bag of the soft copper band embossing screen of 0.1mm, and places the drainage thread 5 that many tinned copper wires constitute between lapping layer 4 and screen 6.
