Summary of the invention
The purpose of this utility model is to overcome above-mentioned technological deficiency, provides a kind of used for intelligent electric network fire-resistant composite cable; The utility model can solve problems such as broadband access, equipment electricity consumption, emergency signal transmission simultaneously, satisfies effectively that cable was both prevented fires, fire-resistant requirement, the corrosivity of the combustion product that decomposes when reducing cable fire simultaneously and the amount of smoke of generation.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The fire-resistant composite cable of a kind of used for intelligent electric network, comprise cable core, packed layer, band, glass cord, oversheath, it is characterized in that: described cable core comprises a plurality of conductors and fiber unit, skin at each conductor is provided with fireprotection layer, fireprotection layer is outside equipped with insulating barrier, arranged outside at insulating barrier has fiber unit, described cable core is outside equipped with band, and between band and cable core, be provided with packed layer, both sides in the radial direction at cable are provided with glass cord, and described glass cord is located between band and the oversheath.
Described conductor is the stranded formation of stranded copper wire.
Described fireprotection layer is a mica tape.
Described insulating barrier is a halogen-free and low-smoke flame-retardant polyolefin.
Described packed layer adopts the glass fibre material.
Described band adopts the glass fibre material.
Described oversheath is a halogen-free and low-smoke flame-retardant polyolefin.
Advantage of the present utility model shows:
1, between conductor and insulation, designs refractory insulating layer, strengthened its fire protecting performance.Insulating barrier and outer jacket all adopt flame-retardant low-smoke halogen-free polyolefin material; stranding band and packed layer all adopt the resistant to elevated temperatures glass fiber material of low smoke, zero halogen; if when suffering flame combustion; can not burn for about 900 ℃ in temperature; and stop flame to pass; secluding air; the protection cable insulation is avoided burning; be provided with glass cord in cable heart both sides; strengthened the fire resistance of cable; and when burning takes place for band and packed layer, can not discharge toxic gas as hydrogen chloride and a large amount of smog, meet environmental protection requirement.
2, cable core of the present utility model is provided with conductor and fiber unit simultaneously, making its current collection power cable and optical cable is one, the function that possesses electric power transfer and fiber-optic communications traffic simultaneously, and the two in transmission course owing to use insulating barrier to cut off, therefore signal can not produce interference each other.
3, the utlity model has characteristics such as high reliability data transmission, price be low, easy to connect, simultaneously external diameter little, in light weight, take up room little; Secondary wiring when avoiding installing reduces engineering cost.
4, the utility model uses the Optical Fiber Composite low-voltage cable to go into as intelligent grid user termination, can save resources such as a large amount of metals, pipeline, plastics, meets energy-saving and cost-reducing requirement.
