Into the semi-conductive layer extruded is bonded with crosslinked polyetylene insulated 130 close and firm of layer, with crosslinked polyetylene insulated layer 130
Interface is smooth.
Comprehensive shielded layer 200 is arranged on the outer surface of insulated wire cores 100, specifically by the weight on insulation screen 140
The anti-copper strip layers 230 of pricking of lap wound packet semi-conductive buffer layer 210+ shielding layer of copper wires 220+ are formed, and are for uniform electric field, are shielded outer
Portion's electromagnetic interference.
Semi-conductive buffer layer 210, specifically by Semi-conductive buffer band be overlapped it is wrapped form, can effectively reduce outside it in this way
It dredges around copper wire to the external force role and influence of insulation shielding, effectively can be joined together to carry short circuit around copper wire by dredging outside it
Fault current, it is ensured that insulation shielding is intact.
Shielding layer of copper wires 220, is specifically dredged to be wound on semi-conductive buffer layer 210 by annealed copper wire and forms, and structure is according to gold
Belong to shielding failed shorted current capacity to determine.
It is anti-to prick copper strip layer 230, specifically by soft copper band gap closely on shielding layer of copper wires 220, and soft copper band
Lapping direction and copper wire are dredged opposite and anti-copper strips of pricking comes into full contact with brass wire shielding around direction, can ensure that fault current is equal in this way
It is even to pass through each copper wire.
Comprehensive waterproof layer 300 is arranged on the outer surface of comprehensive shielded layer 200, is specifically by instead pricking copper strip layer 230
The wrapped non-conductive water blocking layer 310+ of upper overlapping extrudes polyethylene waterproof layer 320 and forms, and is for external water to be avoided to enter
To comprehensive shielded layer 200, the integral waterproofing performance of the application is improved.
Non-conductive water blocking layer 310 is specifically formed, and lapping direction pricks copper with anti-by the overlapping of non-conductive waterstop is wrapped
Band direction is on the contrary, in this way when having moisture or water penetrates radial direction waterproof layer, and non-conductive waterstop meeting water-swellable is so as to effectively hinder
Sealing longitudinal direction and Radial Flow avoid water from entering comprehensive shielded layer 200.
Polyethylene waterproof layer 320, is specifically extruded by polyethylene sheath material, due to polyethylene separation sleeve compactness very
Good, water absorption is few when meeting water in this way, has extraordinary radial direction water resistance, so as to further improve comprehensive waterproof layer 300
Water resistance.
Comprehensive fire-retardant refuge floor 400 is arranged on the outer surface of comprehensive waterproof layer 300, specifically by polyethylene waterproof
It is overlapped the wrapped wrapped outer refuge floor 430 of interior refuge floor 410+ aluminium wire armoured layers 420+ overlappings on layer 320 to form, is for carrying
The fire protecting performance of high the application.
Interior refuge floor 410 and outer refuge floor 430 are specific all to be formed by the overlapping of halogen-free low-smoke high-flame band is wrapped, it is interior in this way every
The outer refuge floors 430 of fire bed 410+ aluminium wire armoured layers 420+ can form fireproofing of cable wall, have preferable fire insulation, fire-retardant, mechanical anti-
Shield acts on.
In addition, in order to further improve fire protecting performance, the aluminium wire armoured direction of aluminium wire armoured layer 420 and interior refuge floor 410
Lapping direction it is opposite.
Integrated protection layer 500 is arranged on the outer surface of comprehensive fire-retardant refuge floor 400, specifically by outer refuge floor 430
On the wear-resisting auxiliary sheaths 520 of the main sheath 510+ of low smoke, zero halogen that extrude form, be for further improving the corrosion-resistant of the application
And wear-resisting property, improve the service life of the application.
The main sheath 510 of low smoke, zero halogen, specifically by environment-protective halogen-free low-smoke polyolefin jacket material or environment-protective halogen-free low-smoke
Elastomer sheathing material extrudes, and is specifically produced by extrusion molding host.
Wear-resisting auxiliary sheath 520, is specifically extruded by polyurethane elastomer sheathing material, is specifically also given birth to by extrusion molding subsidiary engine
Production.
In addition, the main sheath 510 of low smoke, zero halogen and wear-resisting auxiliary sheath 520 be when extrusion head merges, between without
Layering, and 5%~10% that wear-resisting 520 thickness of auxiliary sheath is the main sheath 510 of low smoke, zero halogen.
Since there is the main sheath 510 of low smoke, zero halogen preferably cold-resistant and weather resistance to meet low temperature and the ring of preventing ultraviolet irradiation
Border requires, and the wear-resisting property of wear-resisting auxiliary sheath 520 and anti-mechanical damage better performances, can effectively prevent outside cabling process
Injury of the power to cable cover(ing), by the setting of above structure, the application ensure cable can be really achieved in use from
Destruction of the animal (such as termite, mouse) to cable is physically effectively prevent, to the environmental protection of laying place.
In addition, material used in cable is formed in the application, such as：Oxide cross-linking type semiconductive shieldin material, crosslinking are poly-
Ethylene insulation, not peelable insulation peroxide cross-linking type semiconductive shieldin material, Semi-conductive buffer band, non-conductive waterstop,
