Abstract
The invention discloses a flame-retardant type modified ternary silicon rubber insulated cable which comprises four conductors wrapped with insulating layers, wherein the conductors wrapped with the insulating layers use a compression-resistant core as a center and can be mutually twisted and bundled to form a cable core, a diamond hole is arranged in the compression-resistant core, the exterior of the cable core is wrapped with a wrapping layer, a packing layer is arranged between the wrapping layer and the cable core, a tensile steel wire which is used for wrapping a protective layer is arranged in the packing layer in an annular distribution, and a sheathing layer is wrapped on the wrapping layer. The cable provided by the invention has a reasonable design, the diamond hole arranged in the compression-resistant core at the center of the cable core can play a role in buffering the extrusion from an external force, thus the cable core of the cable can be well protected; the tensile steel wire wrapped the protective layer can be arranged in the cable packing layer, so that the cable core can be changed into a tensile cable core and then the structural strength can be obviously enhanced; and besides, the packing layer is made of a fire-resistant flame-retardant material, thus the fire-resistant flame-retardant property can be improved and the service life of the cable can be prolonged.
Description
Technical field:
The present invention relates to the cable technology field, relate in particular to a kind of flame retardant type modification ternary silicon rubber insulated cable.
Background technology:
For rubber sleeve flexible cable, improve the comprehensive flame retardant level of whole cable for the colliery, have great significance for the safety in production in colliery and the safe operation of cable.The comprehensive flame retardant level of rubber sheathed flexible cable for mine comprises the flame retardant level of high-molecular organic materials such as insulation, filling, band and oversheath.
The employed insulating material of present domestic rubber sheathed flexible cable for mine is mainly the epoxy glue of ethylene-propylene diene copolymer and natural butylbenzene, and the fire-retardant oxygen index level of these two kinds of materials is respectively between 16-18, with respect to low too many of the comprehensive oxygen index level of mining cable.
In order to adapt to the demand of coal industry, improve the whole oxygen index of cable, the flame retardant level that solves insulating material just seems and is even more important.Antimony oxide must be used with the compound that contains halogen as fire retardant, just can give full play of fire retarding effect.Therefore we add an amount of antimony oxide and cooperate the oxygen index (oxygen index can reach 28) of the decabromodiphenyl oxide of certain umber with raising EPDM insulating cement in ethylene-propylene diene copolymer.With the fire retardant trielement ethylene-propylene rubber is to insulate, be filling, be the high flame-retardant cable of sheath with neoprene, haloflex and chlorosulfonated polyethylene with heat-resistant fireproof materials such as glass rope and glass fibre belts.
This outer cable receives external influence, and mutual extrusion causes certain damage between the conductor, and the structural strength of cable does not reach the demand of actual working environment simultaneously.
Summary of the invention:
In order to remedy the deficiency of prior art, the object of the invention provides a kind of flame retardant type modification ternary silicon rubber insulated cable, and reasonable in design satisfies the high use occasions of flame-proof explosion-proof requirement such as mining and peculiar to vessel
Technical scheme of the present invention is following:
