Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, a fire-resistant branch cable comprises a branch cable main body 1, wherein the branch cable main body 1 is connected with a main cable 3 through a conductor connector 2, and one side of the branch cable main body 1 is fixedly connected with a branch cable 4; the main cable 3 comprises a main conductor 31, and an inner insulating layer 32, a flame-retardant glass layer I33, an outer insulating layer 34, an inner sheath 35 and an outer sheath I36 are sequentially arranged outside the main conductor 31; the branch cable 4 comprises a branch conductor 41, and an insulating layer 42, a mica wrapping layer 43, a flame-retardant glass layer II 44 and an outer sheath II 45 are sequentially arranged outside the branch conductor 41.
The main conductor 31 and the branch conductor 41 are both made of high-quality copper conductors, and have high conductivity. The inner insulating layer 32 and the outer insulating layer 34 are both made of rubber materials, so that excellent insulating property is achieved, and the influence of current leakage on personal safety is avoided. The flame-retardant glass layer I33 and the flame-retardant glass layer II 44 are both glass fiber belts and have the characteristics of high temperature resistance, heat preservation, heat insulation and the like. Inner sheath 35 adopts the metal sheath can effectually carry out fire-retardant to external high temperature, and has strengthened tensile, compressive strength of cable, prevents that the rat insect from gnawing the cable, and then improves the life of cable. The outer sheath I36 and the outer sheath II 45 both adopt high-flame-retardant low-smoke halogen-free polyolefin, so that the temperature resistance level is improved, and the fire resistance level and the anti-electromagnetic interference capability of the product are effectively improved. The mica lapping layer 43 adopts two layers of auro mica tapes or synthetic mica tapes, the overlapping rate is 30-50%, and the effect that the higher the temperature is, the harder the fire-resistant layer is can be realized.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
