Detailed Description

Please refer to fig. 1 to 3:

a novel insulated cable, comprising:

the heat insulation protective sleeve comprises a protective sleeve 1 and a core wire 9, wherein the core wire 9 is positioned at the inner periphery of the protective sleeve 1, the inner wall of the protective sleeve 1 is connected with an outer flame-retardant sleeve 2, the inner wall of the outer flame-retardant sleeve 2 is connected with a heat insulation sleeve 3, and the periphery of an insulation sleeve 8 is wrapped with an inner flame-retardant sleeve 7;

specifically, do benefit to the protection that carries out the first layer to heart yearn 9 through setting up lag 1, and outer flame retardant cover 2 does benefit to and reduces the speed of outside flame to heart yearn 9 burning, and reduce the speed that other structures of outer flame retardant cover 2 inside are burnt out, and interior flame retardant cover 7 does benefit to the speed that reduces the heart yearn 9 of spontaneous combustion to the other peripheral structures of internal flame retardant cover 7 burning, consequently, the holistic flame retardant efficiency of cable has been promoted, it insulates against heat to protect to heart yearn 9 to combine the radiation shield 3 again, do benefit to and reduce high temperature to the fusing speed of heart yearn 9, in order to avoid heart yearn 9 by high temperature fast fusing and damage.

The inner wall of the heat insulation sleeve 3 is connected with a plurality of elastic buffer strips 4 which are uniformly distributed in an annular shape, a buffer cavity 12 is formed in each elastic buffer strip 4, a rubber buffer tube 13 is embedded in each buffer cavity 12, a buffer belt 5 is connected between every two adjacent elastic buffer strips 4, each buffer belt 5 is in a grid hollow shape, and a plurality of elastic buffer strips 4 are in a fan shape;

further, when the cable is extruded by the foreign object, pressure can cause elastic buffer strip 4 and cushion chamber 12 to warp together, because elastic buffer strip 4 is fan-shaped, do benefit to the lifting spring buffer strip 4's lifting surface area, consequently, through combining together of elastic buffer strip 4 and cushion chamber 12, do benefit to and carry out one-level buffer protection to heart yearn 9, because elastic buffer strip 4 after the deformation can extrude rubber buffer tube 13 and warp, rethread rubber buffer tube 13 carries out second grade buffer protection to heart yearn 9, because the buffer band 5 of net fretwork form is connected adjacent elastic buffer strip 4, elastic buffer strip 4 can drive buffer band 5 and produce deformation together, to sum up, do benefit to subduct the extrusion dynamics of foreign object to heart yearn 9, the protection effect to heart yearn 9 has been promoted, prevent that heart yearn 9 from being taken place by the condition of extrusion rupture, the effectual life who prolongs heart yearn 9.
