Description
Technical field
The utility model is related to electrical equipment technical field, and in particular to outdoor armored cable.
Background technology
With the fast development of China's economy, more and more extensively, the development of field of cables is also more for the use of cable
Rapidly, diversified trend is presented for the variety requirement of cable, new requirement, room especially is proposed to the cable of outdoor application
The outer cable used high intensity, high mechanical power and it is anticorrosive in terms of have higher requirement.Used at present in outdoor general
Logical cable is general more soft, is unfavorable for outdoor direct burial, and easily by mechanical damage, is run under natural environment big
The pressure that the natural environments such as wind, rainfall, snowfall, Exposure to Sunlight are brought is highly prone to corrode, and the aging speed for accelerating cable is used for a long time
Degree, causes have severe compromise in the use of cable.
The content of the invention
Technical problem to be solved in the utility model be overcome at present common cable can not for a long time outdoor application,
There is provided a kind of outdoor armored cable for the problems such as anti-natural calamity ability is poor.
Outdoor armored cable, it is characterised in that the cable includes conductor, conductor band, semiconductive conductor shield, crosslinking
Polyethylene layer, semiconductive insulation shield layer, copper strip shielding layer, armor, oversheath and sheath tear rope, described conductor
Outer extrude is extruded outside conductor band, described conductor band outside semiconductive conductor shield, described semiconductive conductor shield
Extrude and semiconductive insulation shield layer is extruded outside crosslinked polyetylene insulated layer, described crosslinked polyetylene insulated layer, described partly leads
Copper strip shielding layer is extruded outside body insulation screen, described copper strip shielding layer outer extrudes extrudes outside armor, described armor
Oversheath, is vertically arranged with least one sheath tear rope between described armor and oversheath.
Described armor is corrugated aluminum pipe armor.
Described oversheath is low-smoke halogen-free flame-retardant sheath.
Described sheath tear rope is formed using Polyamide Yarns is stranded
Outdoor armored cable of the present utility model, adds corrugated aluminum pipe armor, is more suitable for outdoor direct burial, resistance to mechanical power
It is stronger, enhancing tensile strength, compression strength, extension cable is in the life-span of outdoor application, and anti-natural calamity condition is strong, aging speed
Slow down, and improve cable electromagnetism interference performance, improve the transmission performance of cable；Environmental requirement is met using material simultaneously,
It is lightweight, it is readily transported and lays, the cost of material is low, there is higher economic benefit and marketing meaning.
Brief description of the drawings
Fig. 1 is the longitudinal sectional drawing of outdoor armored cable of the present utility model；
Wherein, conductor 1, conductor band 2, semiconductive conductor shield 3, crosslinked polyetylene insulated layer 4, semiconducting insulation screen
Cover layer 5, copper strip shielding layer 6, armor 7, oversheath 8, sheath tear rope 9.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1：Outdoor armored cable, the cable includes conductor 1, and conductor band 2, semiconductive conductor shield 3 is handed over
Join polyethylene layer 4, semiconductive insulation shield layer 5, copper strip shielding layer 6, armor 7, oversheath 8 and sheath tear rope 9, institute
Extruded outside the conductor 1 stated and extrude semiconductive conductor shield 3, described semiconductive outside conductor band 2, described conductor band 2
Extruded outside conductor shield 3 and extrude semiconducting insulation screen outside crosslinked polyetylene insulated layer 4, described crosslinked polyetylene insulated layer 4
Cover to extrude outside layer 5, described semiconductive insulation shield layer 5 and extrude armor outside copper strip shielding layer 6, described copper strip shielding layer 6
7, armor 7 is corrugated aluminum pipe armor, it is ensured that good Magnetic Shielding Effectiveness, anti-glitch, and makes cable resistance to mechanical power
Improve, be easy to cable directly buried installation, described armor 7 extrudes oversheath 8 outside, oversheath 8 is low cigarette with resistance to corrosion
Halogen-free flameproof sheath, there is preferable mechanical performance and fire resistance, improves cable security in use, described armor
At least one sheath tear rope 9 is vertically arranged between 7 and oversheath 8, sheath tear rope 9 is formed using Polyamide Yarns is stranded,
Anti- pull effect is effectively played, while the heat that effectively absorbing cable gives out in use, prevents cable rubber phase
Mutual adhesion, and have fire protection flame retarding function, improve the security that cable is used.
