Abstract
The invention discloses a fireproof flexible control cable for an elevator. The fireproof flexible control cable for the elevator comprises a cable core, flame retardant filler is arranged in the interval in the cable core, the outermost layer of the cable core is wrapped in a sheath layer in an extrusion mode, and the cable core is formed by jointly stranding an insulating cable core located in the center of the cable core and six insulating cable cores wrapped outside the central insulating cable core in an extrusion mode, and three ceramic fireproof compound tape wrapping tape layers are arranged between the cable core and the sheath layer. The fireproof flexible control cable for the elevator has obvious fireproof and high-temperature isolating functions, thereby effectively protecting the inner structure of the cable from mechanical changes or electric performance changes. The fireproof flexible control cable for the elevator has the advantages of being free of poison and smell, resistant to high and low temperatures, resistant to ozone aging, resistant to weather aging, good in electric insulating performance and the like.
Description
?
Technical field
The present invention relates to power cable field, specifically a kind of elevator fireproof flexible control cables.
Background technology
Now all can lay different cables in many occasions, to meet the needs of communication, energising etc.But in the time that fire occurs, fire will prolong along cable place combustion and spread to other places.Add up according to fire department, in Urban Fires, wherein more than 2/3 because causing that cable fire spreads, electrical equipment fault or cable traffic overload cause, in while many fire in the past, what cause personal life danger and " secondary harm " is mainly often acid gas and the toxic gas discharging after cable fire.Fireproofing of cable technology more and more causes people's concern, and becomes an important development direction of line cable industry.
Traditional fireproof cable is mounted in copper pipe, fills high temperature resistant solid material between copper pipe and cable, needs solid material pad device, vertical bag equipment and welding equipment etc. in production and manufacture process.Material and facility cost of investment is very high, thereby it is many that manufacturing cost has been increased.In addition, because high temperature resistant protective sleeve is copper pipe structure, filling be solid material, so Cable Bending Radius is little, particularly elevator requires softness with power cable and control cable, brings many inconvenience of installing to user.
Summary of the invention
Technical problem to be solved by this invention is to provide the elevator fireproof flexible control cables of a kind of nontoxic, tasteless, high-low temperature resistant, resistance to ozone aging, weather-proof aging, good electrical insulation capability and mechanical performance.
A kind of elevator fireproof flexible control cables of the present invention, comprises cable core, and the gap of cable core is provided with fire-retardant filler, and cable core outermost layer extrudes restrictive coating; Its cable core is by being positioned at an insulated wire cores at cable core center and being extruded in common stranded the forming of the outer six roots of sensation insulated wire cores of central insulation core; Between cable core and restrictive coating, be provided with three layers of ceramic fire prevention composite band belting layer.
Further improve, described insulated wire cores is made up of conductor and the insulating layer of conductor that is extruded in outside conductor.
Further improve, described ceramic fire prevention composite band belting layer adopts wrapped the forming of mylar band.
Further improve the PE restrictive coating that described restrictive coating adopts PE material to make.
Further improve, described insulating layer of conductor adopts fluoroplastics to make.
Beneficial effect of the present invention is:
1, described fire-retardant filler is flame-retardant low-smoke halogen-free filler, can realize fire-retardant object, because flame-retardant low-smoke halogen-free filler is not halogen-containing, do not produce toxicity, and does not contain heavy metal, therefore harmless to people's health, environmental protection.
2, described insulating layer of conductor adopts the insulating layer of conductor that fluoroplastics are made; That fluoroplastics have is high temperature resistant, do not prolong the characteristics such as combustion, and the insulating layer of conductor that adopts fluoroplastics to make can effectively reduce cable and in the time that fire occurs, occur prolonging the probabilities such as combustion.
3, the present invention utilizes fireproof jointing sheath effectively to protect the internal structure of cable that machinery variation and electrical property variation do not occur.
4, fireproof jointing sheath of the present invention is arranged in restrictive coating; in use restrictive coating can well protect fireproof jointing sheath to avoid the damage of external environment condition; in the time of flame combustion restrictive coating, under the effect due to fireproof jointing sheath, can well protect inner conductor thread core.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, described a kind of elevator fireproof flexible control cables of the present invention, comprises cable core, and the gap of cable core is provided with fire-retardant filler 3, and cable core outermost layer extrudes restrictive coating 6; Its cable core is by being positioned at an insulated wire cores at cable core center and being extruded in common stranded the forming of the outer six roots of sensation insulated wire cores of central insulation core; Between cable core and restrictive coating 6, be provided with two-layer ceramic chemoprevention fire composite band belting layer 5, between two-layer ceramic chemoprevention fire composite band belting layer 5, be also provided with fireproof jointing sheath 4.
Described insulated wire cores is made up of conductor 1 and the insulating layer of conductor 2 that is extruded in outside conductor 1; Described ceramic fire prevention composite band belting layer 3 adopts that mylar band is wrapped to be formed; The PE restrictive coating that described restrictive coating 6 adopts PE material to make;
Described insulating layer of conductor 2 adopts fluoroplastics to make; That fluoroplastics have is high temperature resistant, do not prolong the characteristics such as combustion, and the insulating layer of conductor that adopts fluoroplastics to make can effectively reduce cable and in the time that fire occurs, occur prolonging the probabilities such as combustion.
It has possessed the good fundamental characteristics of silicon rubber elastic to the fireproof jointing sheath 4 that ceramic silastic material is made at normal temperatures; there is nontoxic, tasteless, high-low temperature resistant, resistance to ozone aging, weather-proof aging, good electrical insulation capability; also possessed the good processing characteristics of common high temperature silicon rubber, can keep flexible cable state at 40 degrees below zero to 300 degree left and right above freezing.Attack at flame; temperature reaches 800 degree when above; can be converted to rigid sponge ceramic body by original soft condition; the inner hole that produces of fireproof jointing sheath after hardening; be conducive to insulation; sponge ceramic body has the effect of significant fire prevention and obstruct high temperature like this, thereby effectively protects the internal structure of cable that machinery variation and electrical property variation do not occur.
The invention provides a kind of elevator fireproof flexible control cables version and implementation method; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improve and also should be considered as protection scope of the present invention.
