Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of tensile moving mineral insulation fire-resistant control flexible cable.
Background technology
Conventional fire-resisting cable mainly contains two kinds in the market: a kind of is magnesium oxide insulated, another kind is the outer wrapped mica tape of conductor, and magnesium oxide insulated makes trouble, use length to be very restricted, so mostly adopt the outer wrapped mica tape insulation of conductor as fire-resisting cable.Magnesium oxide insulated fire-resisting cable can only be used as fixed installation, the outer wrapped mica tape fire-resisting cable of conductor is also very undesirable as the effect of mobile use, and cable often needs cable can bear certain pulling force in moving process, the outer wrapped mica tape fire-resisting cable of conductor just more seems and cannot be competent at.Therefore, manufacture the control flexible cable that a kind of pull resistance is good, be easy to movement, fire protection flame retarding, become those skilled in the art assistant officer's problem to be solved.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of tensile moving mineral insulation fire-resistant control flexible cable, it is easy to move, stretch-resistance is good, fire protection flame retarding is effective.
A kind of tensile moving mineral insulation fire-resistant control flexible cable the utility model proposes, comprise cable core, be coated on the lapping layer of described cable core outside, the restrictive coating that is coated on the screen of lapping layer outside and is coated on screen outside, lapping layer adopts ceramic silicon elastomeric material to make, restrictive coating adopts special soft polymer rubber sheath material to make, and is provided with tensile device in restrictive coating; Described cable core forms by multiple conducting wires is stranded, and wire comprises the conductor in the middle part of being positioned at and the insulating barrier that is coated on conductor outside, and insulating barrier adopts special soft polymer rubber sheath material to make.
Preferably, conductor adopts stranded the forming of oxygen-free cupreous bundle.
Preferably, to amass be 1.5～10mm to cross-sectional area of conductor
2.
Preferably, tensile device consists of finer wire and the protective layer that is coated on finer wire outside.
Preferably, be provided with two groups of tensile devices in restrictive coating, two groups of tensile devices are positioned at cable core both sides and symmetrical about cable core.
Preferably, screen adopts copper free wire braiding to form, its count >=80%.
In the utility model, the tensile moving mineral insulation fire-resistant control flexible cable proposing comprises cable core, cable core outside is coated lapping layer, screen and restrictive coating successively, lapping layer adopts ceramic silicon elastomeric material to make, restrictive coating adopts special soft polymer rubber sheath material to make, and is provided with tensile device in restrictive coating; Described cable core forms by multiple conducting wires is stranded, and wire comprises conductor and insulating barrier, and insulating barrier adopts special soft polymer rubber sheath material to make.With the cable of above-mentioned structural configuration mode, simple in structure, flexibility good, in cable core both sides, tensile device is set simultaneously, improved the stretch-proof performance of cable, fire retardant performance is good in addition, is easy to mobile use.
