Abstract
The utility model discloses a special cable for a control system for a communication base station, and relates to the technical field of cable manufacture. The cable comprises three mutually-intertwisted insulating conductors. The outer side of the three mutually-intertwisted insulating conductors is sequentially provided with an asbestos-tape heat-preservation isolating layer, a high-temperature non-woven fabric wrapping layer, a low-density polyethylene inner lining layer, an armor layer, a polyurethane elastomer sheath layer, and a low-smoke zero-halogen environment-friendly polyolefin cable-material protective layer. A flame-retardant filling layer is disposed between three mutually-intertwisted insulating conductors and the asbestos-tape heat-preservation isolating layer. Each mutually-intertwisted insulating conductor comprises a copper rod conductor which is wrapped by a teflon insulating layer. The cable is good in physical and mechanical properties and excellent in weather resistance and high temperature resistance, is suitable for high-altitude, big-temperature-difference and gobi environments.
Description
Technical field
The utility model relates to cables manufacturing technical field, particularly the manufacturing technology of special cable for communication base station control system.
Background technology
Along with the development of scientific and technological progress, ICT (information and communication technology), China sets up a large amount of communication base stations in outlying place, these base stations all build on the higher mountain of height above sea level and the Desert of Gobi that is desolate and uninhabited among, day and night temperature difference overall situation is severe.The height that the requirements of base station is all compared, especially important component part electric wire in base station has higher requirement especially, common electric wire easily aging, cold-resistant, non-refractory etc. can not meet above-mentioned specific (special) requirements.And communication base station just in time makes up above-mentioned shortcoming with controlling special cable.Communication base station has good physical and mechanical properties and superior cold-resistant, high-temperature stability with control special cable, meets communication base station under, Gobi desert desert environment large for high height above sea level, the temperature difference and uses.
Utility model content
The utility model object is for above problem, and a kind of have good physical and mechanical properties and superior cold-resistant, high-temperature stability are provided, and meets the communication base station control system special cable under, Gobi desert desert environment large for high height above sea level, the temperature difference.
The utility model comprises three strands of mutual stranded insulated electric conductors, in described three bursts of mutual stranded insulated electric conductor outsides, sets gradually asbestos yarn thermal insulation separation absciss layer, high temperature nonwoven fabrics lapping layer, low density polyethylene (LDPE) inner covering, armour, polyurethane elastomer sheathing layer and low-smoke halogen-free environment cable material of polyolefin overcoat; Between described three strands of mutual stranded insulated electric conductors and asbestos yarn thermal insulation separation absciss layer, fire-retardant packed layer is set; Per share described insulated electric conductor comprises respectively copper rod conductor, at the poly-full tetrafluoroethene insulating barrier of described copper rod conductor outside parcel.
The utility model insulation adopts poly-full tetrafluoroethene (F46) to extrude, improve that cable is high temperature resistant, anticorrosive, insulated electro performance is superior and the performance such as anti-ambient temperature high (more than 300 ℃), the pre-back-twist device of cabling device band, plays and does not damage core and guarantee the effect of cable roundness; Filler adopts flame-retardant filler, anti-ambient temperature high (more than 200 ℃), high flame retardant, and smokeless, tasteless after burning, suppleness is high, can effectively improve whole cable anti-flammability; During stranding, according to outside diameter of cable size, add corresponding fire-retardant gasket for packing, with cable rounding, be as the criterion, add around one deck asbestos yarn and one deck high temperature nonwoven fabrics, asbestos yarn improves cable heat insulating ability and sealing, effectively isolation cable external high temperature and low temperature refraction, high temperature nonwoven fabrics raising cable is high temperature resistant and fire resistance, effectively improves whole cable safe application performance; Inner covering adopts low density polyethylene (LDPE) to extrude, and this material has the features such as clean environment firendly, corrosion-resistant, oil resistant, can effectively protect whole cable core and the effective buffer action of armour; Restrictive coating adopts polyurethane elastomer cable material to extrude to have that hardness range is wide, stretching and tearing strength is high, performance adjustable extent is large, wear-resisting, oil resistant, ozone resistance are good, shock-absorbing radioresistance and the feature such as resistance to permeability is good.Effectively guarantee that cable is large at high height above sea level, the temperature difference, normal power-up is used under the desert environment of Gobi desert, meets the requirement of controlling special cable for communication base station under particular surroundings.Overcoat adopts anti-ant, protection against rodents low-smoke halogen-free environment cable material of polyolefin to extrude, and has the features such as fire-retardant, low cigarette, Halogen, clean, environmental protection.After burning, solid does not come off, and environmental hazard is little, effectively guarantees not to be subject under cable lowered in field environment the infringement of harmful organism.
Armour described in the utility model is galvanized steel strip armour or zinc plated mild carbon steel silk armour; greatly improve cable tensile strength and resistance to extraneous extruding force performance; be convenient to fall laying and the buried-pipe laying of cable, effectively protect 2 stretch effects electrical properties of cable core and insulating barrier and insulation property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises three strands of mutual stranded insulated electric conductors 1, in three bursts of mutual stranded insulated electric conductor 1 outsides, sets gradually asbestos yarn thermal insulation separation absciss layer 2, high temperature nonwoven fabrics lapping layer 3, low density polyethylene (LDPE) inner covering 4, galvanized steel strip armour 5, polyurethane elastomer sheathing layer 6 and low-smoke halogen-free environment cable material of polyolefin overcoat 7; Between three strands of mutual stranded insulated electric conductors 1 and asbestos yarn thermal insulation separation absciss layer 2, fire-retardant packed layer 8 is set; Per share insulated electric conductor 1 comprises respectively copper rod conductor 9, at the poly-full tetrafluoroethene insulating barrier 10 of copper rod conductor 9 outside parcel.
