Wrap the sheath. The cross section of the conductor is generally 0.75-2.5mm 2 , the shielding layer is shielded with copper tape or copper wire, and the overlapping ratio of the copper tape shielding wrap should not be less than 15%, and the copper wire shield can be tinned or non-tinned round copper wire weave. The utility model uses cross-linked polyethylene as insulation, which reduces the working capacitance, improves the insulation resistance, improves the withstand voltage characteristics, and has excellent flame retardancy; when the cable material is burned, the pH value and conductivity of the halogen gas and gas aqueous solution are low. It has low corrosion performance; the cable generates less smoke when it burns, and the cable has good shielding performance, excellent resistance to external electromagnetic field interference and no external interference.
Description
Technical field:
The utility model relates to control cable, relates in particular to a kind of low smoke and zero halogen environmental-protection flame-retardant intrinsic safety system control cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
The utility model content:
The purpose of this utility model provides a kind of low smoke and zero halogen environmental-protection flame-retardant intrinsic safety system control cable, has solved cable because electric spark and thermal effect cause the problem of explosion hazard gases blast and cable selfcapacity and distributed inductance.
Technical scheme of the present utility model is as follows:
Low smoke and zero halogen environmental-protection flame-retardant intrinsic safety system control cable comprises conductor, insulating barrier, it is characterized in that described conductor outer wrapping insulating barrier, insulating barrier outer wrapping band, band outer wrapping screen, screen outer wrapping sheath.
Described cross-sectional area of conductor is generally 0.75～2.5mm
2
Described screen adopts copper strips or copper wire shielding, and copper strips shields wrapped Duplication should be not less than 15%, and the copper wire shielding can be adopted zinc-plated or not zinc-plated circular copper wire braiding.
The material that the utility model adopted is:
(1) conductor: conductor material is that oxygen-free copper bar draws the lead that forms.Conductor should satisfy among the GB/T3956 the 1st, the performance requirement of 2 kind of conductor, and soft junction structure control cable can adopt the 5th kind of conductor.Cross-sectional area of conductor is generally 0.75～2.5mm
2
(2) insulation: because the rated voltage of control cable is lower, be generally 450/750V,, do not need the dry cross-linking type so adopt the crosslinked with silicane type to get final product as the crosslinked polyethylene (XLPE) of insulation.Organosilane crosslinked polyethylene can reach 90 ℃ than PVC temperature resistant grade height, and uses common screw rod to extrude, and the warm water environment is crosslinked, processes very convenient.Also used vapour is crosslinked, to enhance productivity.
(3) stranding and cable core are wrapped: the common core number of control cable is more, keeps the cable rounding the most key.Cable stranding outermost layer direction of lay is a dextrad, adopt the 1st, the outermost layer twisting pitch of the cable of 2 kind of conductor structure is not more than the outside diameter of cable 20 times; Adopt the cable twisting pitch of the 5th kind of structure conductor to be not more than 16 times of the outside diameters of cable; Twining package tape is selected Halogen material twining package tape for use.
(4) shielding and armouring: copper strips or copper wire shielding are adopted in the shielding of low smoke, zero halogen control cable.Copper strips shields wrapped Duplication should be not less than 15%, and the copper wire shielding can be adopted zinc-plated or not zinc-plated circular copper wire braiding, and armouring adopts the galvanized steel strip bilayer wrapped, and the japanning steel band should be avoided using owing to contain noxious substance in the lacquer.
(5) sheath: sheath adopts polyolefin.According to the requirement of intrinsic safety system, the color of sheath is blue, so that distinguish with cable with the non-intrinsically safe safety system.
The utility model has the advantages that:
The utility model crosslinked polyethylene is insulation, reduces mutual capacitance, improves insulation resistance, improves voltage-resistent characteristic, has good flame retardant property; Halogen gas, gas pH value of water solution and the conductivity of overflowing during the cable material burning are low, have the low-corrosiveness energy; It is few to generate smog during cable fire, and cable has good shielding properties, and good anti-external electromagnetic field disturbs and do not produce external interference.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Low smoke and zero halogen environmental-protection flame-retardant intrinsic safety system control cable comprises conductor 1, insulating barrier 2, described conductor 1 outer wrapping insulating barrier 2, insulating barrier 2 outer wrapping bands 3, band 3 outer wrapping screens 4, screen 4 outer wrapping sheaths 5.
Described conductor 1 cross section is generally 0.75～2.5mm
2
Described screen 4 adopts copper strips or copper wire shielding, and copper strips shields wrapped Duplication should be not less than 15%, and the copper wire shielding can be adopted zinc-plated or not zinc-plated circular copper wire braiding.
