Description
Technical field
The utility model relates to a kind of cable, the concentric type conductor screen cable that to be specifically related to a kind of concentric type conductor be screen.
Background technology
Entered since 21 century, countries in the world are all more and more paid attention to for environmental protection, and some industrially developed country have all worked out very harsh environmental regulation, also environmental protection have been proposed concrete requirement at cable industry.
At civilian electric power facility project (but places such as extensive use power station, power plant, skyscraper, tunnel, subway, computer room, mobile base station), common China is that conventional plastic insulation power cable brings the problem of many deficiencies can for engineering design, transmission and distribution network operation, civilian installation not with the structure of core formula conductor during the lv power cable product structure design; Especially at the power cable of mobile base station use, the client has higher requirement, as: Halogen, environmental protection, weather-proof, low inductance, high flame retardant characteristic etc., conventional plastic insulation power cable can not meet the demands.Mainly there are following three shortcomings in conventional plastic insulation power cable aspect cable design and the practicality:
1, interference free performance is poor.When containing higher harmonic components in the electric current that cable itself is carried, cable can produce electromagnetic interference to the electronic equipment around it; Otherwise extraneous electromagnetic interference also can be coupled on the cable core, to the various electric generation electromagnetic interference of joining with cable.
2, weatherability is poor, and conventional plastic insulation power cable is aging easily under environment and climate change, is prone to fault in the use, and useful life is shorter.
3, environmental-protecting performance is poor, and the common cable material does not possess the low smoke and zero halogen characteristic, easily produces pernicious gas in the combustion process, is unfavorable for biological environment and health.
4,, because of unshielded layer, under the galvanomagnetic effect effect of powerful lightning current, produce overvoltage unavoidably, and cause the damage of insulating barrier or breakdown along the cable that lays in the skyscraper.Because this body structure of lv power cable existing problems, and then various interference that caused and harm problem are increasingly sophisticated and serious.
The utility model content
At the problems referred to above, the purpose of this utility model provides a kind of concentric type conductor that adopts as screen and the good concentric type conductor screen cable of shield effectiveness.
Concentric type conductor screen cable, comprise at least one cable core of being made up of conductor and insulating barrier, this cable core skin is provided with oversheath, is provided with conductor layer between described oversheath and the cable core, described conductor layer comprises the multiply conductor, the multiply conductor be distributed in cable core around.
Described multiply conductor can be set to the concentric type conductor, also can not be arranged to the concentric type conductor, for cable has good shield effectiveness, preferably the multiply conductor is arranged to the concentric type conductor and is adopted the mode of circumferentially twining to twine with the average headway spiral, prevent when carrying electric current electromagnetic interference to the electronic equipment around it, simultaneously extraneous electromagnetic interference can not be coupled on the cable conductor line yet, therefore the various electric generation electromagnetic interference that can not join to cable.
Described cable core is one, is provided with twining package tape between cable core and the oversheath, and described conductor layer is coated on the cable core, and twining package tape is coated on the conductor layer.Be provided with copper strips between described conductor layer and the twining package tape, copper strips is wrapped on the conductor layer and with conductor layer and tightens.Described multiply conductor is the concentric type conductor, and described multiply conductor is wrapped on the insulating barrier in the same way, these concentric type conductors be wrapped on the insulating barrier common form spiral-shaped.
Described cable core is at least two, is provided with inner covering, twining package tape between cable core and the oversheath, and described inner covering is coated on the cable core, and described conductor layer is arranged between inner covering and the twining package tape.Be provided with copper strips between described conductor layer and the twining package tape, copper strips is wrapped on the conductor layer and with conductor layer and tightens.Described multiply conductor is the concentric type conductor, and described multiply conductor is wrapped on the inner covering in the same way, these concentric type conductors be wrapped on the inner covering common form spiral-shaped.
Described oversheath selects for use the material of-40 ℃ of cold resistance, UV resistant, high flame retardant Halogen to form.Therefore cable has good UV resistant radiation characteristic, can be by ultra-violet radiation experiment in 720 hours; Cable has the Halogen characteristic, satisfies IEC 60754-1 and IEC 60754-2 requirement, and halogen content is not more than 5mg/g, and the pH value is not less than 4.3, and conductivity is not more than 10 μ S/mm; Cable has high flame resistance, by IEC 60332-3 bunchy combustion experiment.
The multiply conductor of the conductor of described cable core and conductor layer is annealed copper silk or coating annealed copper silk, so cable has good softness, and the bending radius that makes cable is 8～10 times of the outside diameter of cable.
In order to make cable have good environmental-protecting performance and to meet RoHS (about being limited in the instruction of using some harmful components in the electronic and electrical equipment) requirement, described cable jacket adopts the Halogen material to form.
Described multiply cross-sectional area of conductor sum is arranged to more than or equal to the required zero-line section of cable, and cable conductor layer can use multiply conductor in the conductor layer according to its structure of being made up of the multiply conductor as zero line or earth connection.
Adopted such scheme, the utlity model has good shielding properties and because cable adopts special material to form, so the utility model also has the advantage of good interference free performance, weather-resistant property, environmental-protecting performance and long service life.
