Background technology
In recent years, along with advancing by leaps and bounds of the communication technology, communications industry becomes one of whole world industry with the fastest developing speed, there is quick growth trend in Communication in China industry, along with the needs that communication engineering is built, communication power supply flexible cable is applied more and more extensive in the electrical power trans mission/distribution system of communications office site and building, and existing communication power supply flexible cable, though general communication power supply requirement can be met, but copper conductor material cost is high, cable is without environment-friendly materials, and to cause between power supply without metallic shielding structure or and communication equipment between produce and disturb, the energy-conserving and environment-protective requirement that country advocates can not be adapted to, can not season oneself to cold and have the electrical power trans mission/distribution system of mush area to use.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of communication power supply copper-clad aluminum flexible cable, with alternative pure cu conductor communication power supply flexible cable, not only can meet the performance requirement of original product, and cost is low, lightweight, there is the performances such as softness, corrosion-resistant, low temperature resistant, LSOH anti-flaming environmental protection.
The technical solution of the utility model is such: a kind of communication power supply copper-clad aluminum flexible cable, comprise conductor, described conductor adopt layers of copper volume ratio be 15% soft state copper-clad aluminum conductor strandedly to form, extrude the insulation of LSOH anti-flaming environment-friendly polyolefin outside conductor and form insulated wire cores, four insulated wire cores central authorities surround a LSOH anti-flaming gasket for packing and are twisted into cable core, the outside of described cable core, LSOH anti-flaming gasket for packing is set between two insulated wire cores, LSOH anti-flaming polyester band inner covering is set gradually outside cable core, woven shield, LSOH anti-flaming environment-friendly cold polyolefin oversheath.
Preferably, the soft state copper-clad aluminum conductor line diameter of described conductor is 0.203 ~ 0.511mm, and tensile strength is 138 ~ 172N/mm
2, percentage elongation is 5 ~ 10%.
Preferably, described woven shield adopts line diameter to be 0.160 ~ 0.320mm, and layers of copper volume ratio is the soft state tin-coated copper plated aluminium alloy wire braiding of 15%, and count is greater than 80%.
Preferably, the described oversheath temperature that resists cold is not less than-40 DEG C.
The advantage of technical scheme provided by the utility model is, conductor have employed that soft state copper cover aluminum single line is stranded to be formed, and makes cable have higher flexibility and corrosion resistance, cheap laying installation, weight saving compared with copper core cable, cost reduces, copper clad aluminum conductor cost-saved 45 ~ 60%; Insulated wire cores inside arranges gasket for packing stable insulation core structure, and keeps flexibility.Screen have employed the braiding of soft state tin-coated copper plated aluminium alloy wire and forms, and enhances soft adaptability, improves antijamming capability and overload protection ability; Employing extrudes or wrapped technology, select the insulation of LSOH anti-flaming environment-friendly polyolefin, LSOH anti-flaming gasket for packing, LSOH anti-flaming polyester band inner covering, LSOH anti-flaming environment-friendly cold polyolefin oversheath, improve the performance such as cable cold tolerance, LSOH anti-flaming Environmental Safety.The energy-conserving and environment-protective requirement that country advocates can be adapted to, season oneself to cold and have defeated, the distribution system of mush area to use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Refer to Fig. 1, communication power supply copper-clad aluminum flexible cable involved by the utility model, conductor 1 adopt layers of copper volume ratio be 15% CCA-15A type soft state copper-clad aluminum conductor strandedly to form, extrude LSOH anti-flaming environment-friendly polyolefin insulation 2 outside conductor and form insulated wire cores, four insulated wire cores central authorities place LSOH anti-flaming gasket for packing 3 and are twisted into cable core, outside cable core, LSOH anti-flaming gasket for packing 3 is set in two often adjacent insulated wire cores gaps, LSOH anti-flaming polyester band inner covering 4 is set gradually outside cable core, CCAAT-15A type soft state tin-coated copper plated aluminium alloy wire woven shield 5, LSOH anti-flaming environment-friendly cold polyolefin oversheath 6.
In concrete enforcement, be 0.203 ~ 0.511mm by line diameter, layers of copper volume ratio is the soft state copper-clad aluminum conductor of 15%, many single line bundles (strand) are become conductor 1 by bundle (strand) line machine, on φ 50 ~ φ 90 plastic extruding machine, subregion heats 120 ~ 175 DEG C, conductor 1 is introduced in extrusion die, extrude halogen-free and low-smoke flame-retardant polyolefin insulation 2 and form insulated wire cores, 4 insulated wire cores and a LSOH anti-flaming gasket for packing are twisted into cable core by cabler, direction of lay is dextrad, outside cable core, the gap of insulated wire cores adopts LSOH anti-flaming gasket for packing 3 to fill rounding, and at outer overlapping wrapped 1 ~ 2 layer of LSOH anti-flaming polyester band inner covering 4 of cable core, then cable core is placed on 16 ~ 36 ingot braiding machines, employing line diameter is 0.160 ~ 0.320mm, layers of copper volume ratio is the soft state tin-coated copper plated aluminium alloy wire formation woven shield 5 of 15%, count is greater than 80%, last on φ 90 ~ φ 150 plastic extruding machine, subregion heats 120 ~ 175 DEG C, by the cable after shielding 5, in introducing extrusion die, extrude LSOH anti-flaming environment-friendly cold polyolefin oversheath 6, oversheath 6 temperature that resists cold is not less than-40 DEG C.
