Description
Technical field
The present invention relates to a kind of accompanying-heat cable, relate in particular to the special soft anti-corrosion type of a kind of permanent power ribbon heater.
Background technology
The remote oil gas of carrying adopts pipeline to carry usually; At cold zone; Frost crack pipe may take place make oil and gas leakage, perhaps owing to temperature is crossed the low mobile variation that oil gas solidified make, adopting the accompanying-heat cable heating is a kind of method of generally using; Exist because pipeline institute has macro-corrosion property material through the area, therefore need to adopt the anti-corrosion type ribbon heater.
Summary of the invention
The problem that the present invention will solve provides a kind of that have an anti-corrosion function and keep the constant anti-corrosion type ribbon heater of power output.
In order to address the above problem, the present invention realizes through following technical scheme.
The special soft anti-corrosion type of a kind of permanent power of the present invention ribbon heater, said ribbon heater comprises at least three insulated wire cores that are arranged side by side, and is disposed with lapping layer, sheath, screen, oversheath from inside to outside in the outside of said insulated wire cores.
Further improvement of the present invention is: said conductor is twisted into bundle by thin strand of many busbars or essence and constitutes, and said insulating barrier adopts the perfluoroethylene-propylene insulating material to extrude.
Further improvement of the present invention is: said casing play is processed by the silicon rubber insulation material; Casing play is wound with heating wire outward; This heating wire is connected with power supply at a certain distance, is equivalent to the parallel connection of several resistance, after the power supply energising; Each parallel resistor silk heating, thereby form a continuous heating tape.
Further improvement of the present invention is: said lapping layer adopts and gathers the polytetrafluoroethylene membrane material, and said screen adopts the plastic-aluminum band to make, and said sheath and oversheath adopt the silicon rubber insulation material.
Compared with prior art, the structure and material of the present invention's employing has guaranteed that cable can operate as normal under rugged environment.Pliability of the present invention is good, mechanical strength is high, oil resistance anticorrosion, mould proof growth, flame-resistant high-temperature-resistant performance remarkable; Advantages of good shielding performance, insulation property are good, and the line body is extremely soft; Can bend to Any shape arbitrarily, in special occasions than the laying installation of being more convenient for of the ribbon heater of other type.There is not any startup impulse current at low temperatures yet.
Description of drawings
As shown in the figure: Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of insulated wire cores among Fig. 1
1 conductor, 2 insulating barriers, 3 casing plays, 4 lapping layers, 5 sheaths, 6 screens, 7 oversheaths, 8 insulated wire cores.
Embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is done below and further describe, this embodiment only is used to explain the present invention, protection range of the present invention is not constituted to limit.
As depicted in figs. 1 and 2, the special soft anti-corrosion type of a kind of permanent power of the present invention ribbon heater, said ribbon heater comprises at least three insulated wire cores that are arranged side by side 8; Outside in said insulated wire cores 8 is disposed with lapping layer 4 from inside to outside; Sheath 5, screen 6, oversheath 7.The structure of said insulated wire cores 8 comprises conductor 1, in the outer setting of said conductor 1 insulating barrier 2 is arranged, and the outer setting of said insulating barrier 2 is wound with the casing play 3 of heating wire; Said conductor 1 is twisted into bundle by thin strand of many busbars or essence and constitutes, and said insulating barrier 2 adopts the perfluoroethylene-propylene insulating material to extrude, and said casing play 3 is processed by the silicon rubber insulation material; Be wound with heating wire outside the casing play 3, this heating wire is connected with power supply at a certain distance, be equivalent to the parallel connection of several resistance; After the power supply energising; Each parallel resistor silk heating, thereby form a continuous heating tape, said lapping layer 4 adopts and gathers the polytetrafluoroethylene membrane material; Said screen 6 adopts the plastic-aluminum band to make, and said sheath 5 adopts the silicon rubber insulation material with oversheath 7.
Pliability of the present invention is good, and mechanical strength is high, oil resistance anticorrosion, the flame-resistant high-temperature-resistant performance is remarkable, advantages of good shielding performance line body is extremely soft, can bend to Any shape arbitrarily, in special occasions than the laying installation of being more convenient for of the ribbon heater of other type.
