Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment：A kind of insulation control cable, as depicted in figs. 1 and 2, including cable core 1, cable core 1 are set successively from inside to outside
It is equipped with flame-retardant layer 11, fireprotection layer 12 and restrictive coating 13.
More conductors 111 are provided with cable core 1, conductor 111 is twisted by 10~12 zinc-plated copper wires, conductor
111 outer surface is coated with insulating barrier 112, and insulating barrier 112 is made of to use PVC insulating materials.
As shown in Figures 2 and 3, fireprotection layer 12 designs using double-decker, including is contradicted with the outer surface of insulating barrier 112
Fireprotection layer 1, the periphery of fireprotection layer 1 offers through hole 1211 (see Fig. 3), and fireprotection layer 1 uses polyvinyl chloride
Manufactured flame-resistant insulation plastic plate, there is the characteristic of flame-resistant insulation, the heat in cable core 1 can be spread by through hole 1211, be entered
And reduce the temperature at cable core 1.Fireprotection layer 1 tightens insulating barrier 112（See Fig. 1）Circumferentially array distribution, it is formed centrally within
Hollow structure, hollow structure are arranged to flame-retardant layer 11, and it is organic that flame-retardant layer 11 can select inorganic anti-flaming material to select
Fire proofing is as filler, so that the temperature rise of cable core 1, cable core 1 will not catch fire because temperature is too high.
Fireprotection layer 12 also includes fireprotection layer 2 122, and fireprotection layer 2 122 falls within flame-resistant insulation plastics made of polyvinyl chloride
Plate, there is relatively low burning-point.Silica gel plate 123 is connected between fireprotection layer 2 122 and fireprotection layer 1, silica gel plate 123 is placed in logical
The both sides in hole 1211, silica gel plate 123 separate fireprotection layer 1 and fireprotection layer 2 122, once heat flows out out of through hole 1211
When, heat will be flowed between fireprotection layer 1 and fireprotection layer 2 122, and then make silica gel plate 123 and fireprotection layer 1, fire prevention
