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 modified 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 the high-molecular organic materials such as insulation, filling, band and oversheath.
The insulating material that present domestic rubber sheathed flexible cable for mine uses is mainly the epoxy glue of ethylene-propylene diene copolymer and natural butylbenzene, and the fire-retardant oxygen index level of this bi-material 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.Antimonous oxide is as fire retardant, and the compound that must and contain halogen is used in conjunction with, and just can give full play of fire retarding effect.Therefore we add appropriate antimonous oxide and coordinate the decabromodiphenyl oxide of certain umber with the oxygen index (oxygen index can reach 28) of raising Ethylene Propylene Terpolymer insulating cement in ethylene-propylene diene copolymer.High flame-retardant cable take fire retardant trielement ethylene-propylene rubber as insulation, take heat-resistant fireproof materials such as glass fiber rope and glass fibre belts as filling, take neoprene, haloflex and chlorosulfonated polyethylene as sheath.
This outer cable is subject to external influence, mutually pushes between conductor and causes certain damage, and the structural strength of cable does not reach the demand of actual working environment simultaneously.
Summary of the invention:
In order to make up the deficiencies in the prior art, the purpose of this invention is to provide a kind of flame-retardant modified ternary silicon rubber insulated cable, 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 as follows:
Flame-retardant modified ternary silicon rubber insulated cable; the conductor that comprises four wrap insulate layers; it is characterized in that: the conductor of wrap insulate layer mutual stranded bunchy centered by the resistance to compression core consists of cable core; the resistance to compression in-core is provided with diamond hole; cable core is wrapped with lapping layer; be provided with packed layer between lapping layer and cable core, be provided with in packed layer along the tension steel wire of the packing protective layer of annular spread, lapping layer is wrapped with restrictive coating.
Described flame-retardant modified ternary silicon rubber insulated cable is characterized in that: described insulating barrier adopts the ethylene propylene diene rubber that contains antimonous oxide and decabromodiphenyl oxide.
Described flame-retardant modified ternary silicon rubber insulated cable is characterized in that: it is the several layers of overlapping wrapped formation of glass fibre belt that described lapping layer adopts material, and the wrapped rate of putting up is not less than 40%.
Described flame-retardant modified ternary silicon rubber insulated cable is characterized in that: described packed layer adopts glass fiber rope or glass fibre belt to fill formation.
Advantage of the present invention is:
Reasonable in design of the present invention, the resistance to compression in-core at the cable core center is provided with diamond hole, and cushioning effect is played in the extruding of external force, has well protected the cable core of cable; Be provided with the tension steel wire of packing protective layer in the cable filling layer, make cable core become the tension cable core, structural strength obviously strengthens; Packed layer adopts the material of fire resistant flame retardant in addition, has improved the fire resistant flame retardant characteristic, has extended the useful life of cable.
