Abstract
The utility model discloses a kind of control and instrument system stube cable, comprise three silver-coated copper wire flexible conductors, three silver-coated copper wire flexible conductors are all coated with aluminium foil lapping layer outward, polyethylene foamed insulating barrier forms insulated wire cores, described insulated wire cores is isosceles triangle and is distributed in the compound cable core of control cable core outside formation, after controlling cable core and have the mutual stranded bunchy of alloy conductor of 7 coated Si rubber insulations, coated rock wool belt lapping layer forms, compound cable core is provided with Tarpauling lapping layer outward successively, aluminium-plastic tape lapped shielding layer, ceramic composite fibrous band lapping layer, low-smoke halogen-free polyolefin external sheath layer.The utility model structural design is novel, by controlling three silver-coated copper wire conductors of cable core outside distribution as signal transmssion line, the work of independent stability and high efficiency each other, there is good high temperature resistant, anti-electromagnetic interference, the advantage such as lightweight, laying installation rapid and convenient, can meet the control of high-end special installation and the transmission of the signal of instrument system.
Description
technical field:
The utility model relates to composite cable, relates in particular to a kind of control and instrument system stube cable.
background technology:
Along with scientific and technological high speed development, it is more and more that some are applied to electric wires of particular surroundings, and traditional control and instrument system easily stube cable can not meet high-end special installation user demand completely in requirements such as the transmission rate of product, capability of electromagnetic shielding, weight.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of control and instrument system stube cable, structural compactness is good, there is good transmission rate, capability of electromagnetic shielding, high temperature resistant and heat-proof quality, can meet the control of high-end special installation and the transmission of the signal of instrument system.
The technical solution of the utility model is as follows:
Control and instrument system stube cable, it is characterized in that: comprise three silver-coated copper wire flexible conductors, three described silver-coated copper wire flexible conductors are all coated with aluminium foil lapping layer outward, polyethylene foamed insulating barrier forms insulated wire cores, described insulated wire cores is isosceles triangle and is distributed in the compound cable core of control cable core outside formation, after controlling cable core and have the mutual stranded bunchy of alloy conductor of 7 coated Si rubber insulations, coated rock wool belt lapping layer forms, compound cable core is provided with Tarpauling lapping layer outward successively, aluminium-plastic tape lapped shielding layer, ceramic composite fibrous band lapping layer, low-smoke halogen-free polyolefin external sheath layer.
Described control and instrument system stube cable, is characterized in that: the wrapped rate of putting up of described rock wool belt lapping layer is not less than 45%.
Described control and instrument system stube cable, is characterized in that: the wrapped rate of putting up of described ceramic fibre strip lapping layer is not less than 38%.
The utility model has the advantages that:
The utility model structural design is novel, by controlling three silver-coated copper wire conductors of cable core outside distribution as signal transmssion line, the work of independent stability and high efficiency each other, there is good high temperature resistant, anti-electromagnetic interference, the advantage such as lightweight, laying installation rapid and convenient, can meet the control of high-end special installation and the transmission of the signal of instrument system.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
Control and instrument system stube cable, comprise three silver-coated copper wire flexible conductors 1, as signal, transmission is used, the speed of transmission is fast, good reliability, three outer aluminium foil lapping layers 2 that are all coated with of silver-coated copper wire flexible conductor 1, polyethylene foamed insulating barrier 3 forms insulated wire cores, insulated wire cores is isosceles triangle and is distributed in and controls cable core 4 outsides and form compound cable core, after controlling cable core 4 and have the mutual stranded bunchy of alloy conductor 4-1 of 7 coated Si rubber insulation 4-2, coated rock wool belt lapping layer 4-3 forms, compound cable core is provided with Tarpauling lapping layer 5 outward successively, aluminium-plastic tape lapped shielding layer 6, ceramic composite fibrous band lapping layer 7, low-smoke halogen-free polyolefin external sheath layer 8.
The wrapped rate of putting up of rock wool belt lapping layer 4-3 is not less than 45%, improves its resistance to elevated temperatures.
The wrapped rate of putting up of ceramic fibre strip lapping layer 7 is not less than 38%, has certain heat-proof quality, and in resistant to elevated temperatures environment, stability in use and continuation are superior.
