Description
?
Technical field
The present invention relates to a kind of cable, specifically be a kind of use chemical industry, smelting, commerce, oil, mine etc. inflammable, explosive, directly jeopardize fire resistant flame retardant high-tension cable in the people and the national lives and properties environment (3.6/6-26/35kV) and manufacturing approach.
Background technology
Chemical industry, smelting, commerce, oil, mine etc. inflammable, explosive, directly jeopardize in the environment of the people and national lives and properties; Not only can receive artificial destruction; But also can receive the crushing fire that unartificial accidentalia causes, tend to because of cable not fire resistant flame retardant or fire resistant flame retardant poor performance cause supply of electric power to be interrupted, cause rescuing and have equipment unpowered; And the not fire resistant flame retardant of cable itself has aggravated the condition of a disaster, has finally caused huge personnel, property loss.Existing technical matters is to adopt one deck flame retardant coating promptly as long as stranding cable core flame retardant coating does not have conductor, insulation shielding, three grades of flame retardant coatings of metallic shield; Armouring adopts steel band, steel wire; Not vertical bag embossing alloy aluminum plastic composite strip in the structure of prior art processes, the prior art processes armouring adopts steel band, steel wire can not form smooth rounding face, has gap and corner angle, can not form the oxygen barrier protective layer.
(there is following problem in 3.6/6-26/35kV) production technology process: 1) poor performance of material own causes insulation property, bad mechanical property to tradition fire resistant flame retardant high-tension cable; 2) has only flame retardant coating one; 3) fire resistance of interior oversheath, packing material is poor; 4) inflammable, flame-retarding power is good, and fire resistance is poor; 5) unreasonable structure, armour can not form smooth rounding face, have gap and corner angle, can not form the oxygen barrier protective layer.
Summary of the invention
The objective of the invention is provides a kind of rational in infrastructure in order to overcome the deficiency of prior art, fire protecting performance good the fire resistant flame retardant high-tension cable.
In order to solve the problems of the technologies described above; A kind of fire resistant flame retardant high-tension cable of the present invention; It is characterized in that: comprise inner core; Extruding low cigarette at the outer surface of inner core does not have the fire-retardant inner sheath of chlorine, does not have the outside vertical bag embossing alloy aluminum plastic composite strip of the fire-retardant inner sheath of chlorine at low cigarette, and coating low cigarette at the outer surface of embossing alloy aluminum plastic composite strip does not have the fire-retardant oversheath of chlorine.
Said inner core can be single core; This core comprises inner wire; On the outer surface of inner wire, be provided with first flame retardant coating, at the three-layer co-extruded conductor shield of the first flame retardant coating appearance, insulating barrier and insulation screen, wrapped second flame retardant coating outside insulation screen; Wrapped copper strips screen outside second flame retardant coating, wrapped the 3rd flame retardant coating outside the copper strips shielding.
Said inner core also can be made up of many cores; Every core comprises inner wire; On the outer surface of inner wire, be provided with first flame retardant coating, at the three-layer co-extruded conductor shield of the first flame retardant coating appearance, insulating barrier and insulation screen, wrapped second flame retardant coating outside insulation screen; Wrapped copper strips screen outside second flame retardant coating; Wrapped the 3rd flame retardant coating outside the copper strips shielding, and high flame retardant glass fiber packing is filled in the gap between core, at wrapped the 4th flame retardant coating of high flame retardant glass fiber packing appearance.
Conductor adopts the electrolysis copper wire among the present invention; And three-layer co-extruded conductor shield, insulating barrier, insulation screen outside inner core; The outer lapped insulation shielding of insulation screen flame retardant coating; The outer wrapped copper strips shielding flame retardant coating of copper strips shielding is filled high flame retardant glass fiber packing, and inner sheath adopts the low cigarette of improvement not have the chlorine fire retardant polyolefin.Vertical bag embossing alloy aluminum plastic composite strip forms the oxygen barrier protective sleeve to cable core, and oversheath adopts the low cigarette of improvement not have the chlorine fire retardant polyolefin.The insulating material of high-quality and sheath material; Make it not only possess good insulation performance performance, mechanical performance, good stability also has conductor fireprotection layer, insulation shielding fireprotection layer, metal copper strips shielding fireprotection layer; Form three grades of fireprotection layers; And the stranding cable core is to be provided with the 4th road flame retardant coating in the inner sheath, and inner sheath, oversheath adopt the low cigarette of improvement not have the chlorine fire retardant polyolefin, fills and adopts high flame retardant glass fiber gasket for packing; Armouring adopts embossing alloy aluminum plastic composite strip, and its smooth surface rounding and high-melting-point have played the optimal efficacy of oxygen barrier protection, flame-retardant to whole cable core;
Advantage of the present invention is: insulation property, the mechanical performance of (1) cable are very good; (2) have conductor fireprotection layer, insulation shielding fireprotection layer, metal copper strips shielding fireprotection layer, form three grades of fireprotection layers; (3) interior oversheath is that the low cigarette of improvement does not have chlorine fire retardant polyolefin, packing material to be that high flame retardant glass fiber gasket for packing has possessed fire-retardant, does not prolong the performance of combustion; (4) reasonable in design, vertical bag embossing alloy is plastic-aluminum combined, neither influences bending property, can form the sealing oxygen barrier protective sleeve of smooth rounding again, and burning is put out because of anoxic certainly; (5) anti-flammability, fire resistance, flexibility, bendability are very good, are beneficial to use at various complex environments.
