Abstract

A halogen-free low-smoke flame-retardation instrument cable for a nuclear power station relates to the technology field of cable manufacture. The halogen-free low-smoke flame-retardation instrument cable comprises a cable core; a cabling wrapping layer, a tin-coated copper wire braided total shield layer, an outer wrapping layer, an inner sheath layer, an armor and an outer sheath layer are arranged outside the cable core in sequence; a filling layer is arranged between the cable core and the cabling wrapping layer; the cable core comprises four twisted cables, each cable independently comprises two insulation cores intertwisted together, and a copper strip wrapping unit shielding layer and a unit wrapping layer are arranged outside the intertwisted insulation cores in sequence; a lead wire is arranged between the copper strip wrapping unit shielding layer and the insulation cores; each insulation core independently comprises a conductor; and an inner insulating layer and an outer insulating layer are arranged outside the conductor in sequence. According to the halogen-free low-smoke flame-retardation instrument cable, the structure is simple, material is novel, the double-layer insulation structure, composite shield structure and double-layer wrapping structure are employed, excellent low smoke, halogen free, flame retardation, radiation hardening, anti-interference and cracking resistant performance is provided, and the service life is long.

Description

Used in nuclear power station LSOH anti-flaming instrument cable
Technical field
The utility model relates to the cables manufacturing technical field, particularly a kind of used in nuclear power station LSOH anti-flaming instrument cable.
Background technology
AP1000 is international advanced generation Ⅲ nuclear power technology, has higher fail safe and more excellent economy, and be 60 years designed life.According to national nuclear power Long-and Medium-term Development, plan: to the year two thousand twenty, the Chinese Nuclear Power installed capacity will account for 7% left and right of total installed capacity of electricity capacity, reach 7,500 ten thousand kilowatts.Newly-built nuclear power station will adopt the AP1000 nuclear power technology comprehensively.Used in nuclear power station LSOH anti-flaming instrument cable is mainly used in power supply, signal monitoring, the interlock system of nuclear power station instrument control device, also can be used for communication system, security monitoring, maintenance system, warning system etc.For the AP1000 technology, its supporting instrument cable requires to possess the useful life more than 60 years, and have low smoke and zero halogen, fire-retardant, anti-long term heat ageing, also to have specifically environment resistant, as radiation hardness, anti-LOCA.The main deficiency of existing nuclear power station instrument cable is: shielding properties is poor, capability of resistance to radiation is general, does not reach useful life 60 years.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of common nuclear cables technology, for the special severe operational environment of cable for nuclear power station and the requirement of high security, provide a kind of used in nuclear power station LSOH anti-flaming instrument cable of the AP10000 of meeting cables of nuclear power standard-required.
The utility model comprises cable core, in the described cable core outside, sets gradually stranding lapping layer, tinned copper wire braided overall-shielding layer, outer lapping layer, inner restrictive coating, armour and external sheath layer; Between described cable core and stranding lapping layer, packed layer is set; Described cable core comprises the cable of twisted quad, and every share of cable comprises respectively two mutual stranded insulated wire cores, outside stranded insulated wire cores, sets gradually copper strips wrapped unit screen and unit lapping layer; Between copper strips wrapped unit screen and insulated wire cores, drainage thread is set; Every described insulated wire cores comprises respectively conductor, in the described conductor outside, sets gradually inner insulating layer and external insulation layer.
The utility model conductor adopts the stranded bunchy of several tinned copper wires to form, and the sectional area of conductor is 0.75-2.5mm 2Double insulating layer is respectively inner insulating layer, and material adopts cross-linked polyolefin; External insulation layer, material adopts the LSOH anti-flaming cross-linked polyolefin; Jacket material is halogen-free and low-smoke flame-retardant polyolefin sheathed irradiation material; Packing material is made by the netted split fibre of high flame retardant polyolefin parcel.The utility model is simple in structure, and the material novelty adopts double-layer insulating structure and composite shielding structure and double-deck lapping structure, makes product have the performances such as excellent low cigarette, Halogen, fire-retardant, radioresistance, anti-interference, cracking resistance, life-span be long.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core, in the cable core outside, sets gradually stranding lapping layer 1, tinned copper wire braided overall-shielding layer 2, outer lapping layer 3, inner restrictive coating 4, armour 5 and external sheath layer 6; Between cable core and stranding lapping layer 1, packed layer 7 is set; Cable core comprises the cable 8 of twisted quad, and every share of cable 8 comprises respectively two mutual stranded insulated wire cores 9, outside stranded insulated wire cores 9, sets gradually the wrapped unit of copper strips screen 10 and unit lapping layer 11; Between the wrapped unit of copper strips screen 10 and insulated wire cores 9, drainage thread 12 is set; Every eradication edge core 9 comprises respectively conductor 13, in conductor 13 outsides, sets gradually inner insulating layer 14 and external insulation layer 15.
