Description
Technical field
The utility model is related to the extraordinary electric power of special cable manufacturing technology field more particularly to a kind of novel subway tunnel
Cable.
Background technology
In recent years, with the progress faster of Chinese Urbanization construction, each large size city is all in the city rail that accelerates
The construction of traffic, at the same time China the investment construction dynamics of highway and high-speed railway is also continued to increase.It is every at these
In year newly-increased subway, tunnel construction project, need a large amount of electric wire (especially power cable) matched.Subway,
Tunnel is opposite to be closed, and is drawn badly, and humidity is larger, and personnel also compare concentration, can be withdrawn rapidly in fire for ease of personnel,
Very high low smoke and zero halogen, fire-retardant, moisture-proof requirement thus are proposed to the cable used, it is desirable that it is difficult to burn or fire in fire
Halogen acid gas, the smog of poisonous and harmful effect are not generated when burning, while there is excellent moisture-resisting water-proof performance etc..Existing subway
Tunnel power cable cannot meet actual needs due to material, technique and structure etc. Shortcomings.
Utility model content
The utility model aim is that providing one kind in view of the above problems has Halogen, low cigarette, fire-retardant A classes, block water, prevent
The extraordinary soft power cable in the novel subway tunnel of the performances such as water, protection against rodents, termite-proof, nontoxic, soft.
A kind of extraordinary soft power cable in novel subway tunnel, including cable core, low cigarette is orderly arranged outside each in the cable core
Halogen-free flameproof band wrapping layer, the compound waterstop of the first intumescent block water wrapping layer, the compound waterstop of the second intumescent block water it is wrapped
Layer, Halogen glass fiber belt around the cladding and halogen-free and low-smoke flame-retardant polyolefin external sheath layer.Cable core is by three groups of insulated wire cores and filling
Layer is constituted, and the insulated wire cores are made of conductor and crosslinked polyetylene insulated layer.
Conductor described in the utility model, which should use to select, to be met the 5th kind of plating metal as defined in GB/T3956-2008 or does not plate
The annealing copper conductor of metal layer.
Filled layer described in the utility model is the mineral wool rope filler material with high flame-retardant property.
The compound waterstop of every layer of intumescent of the utility model block water wrapping layer cap rate be not less than 30%.
The beneficial effects of the utility model are:
The utility model has excellent electric property, physics using the 5th kind of copper conductor and crosslinked polyetylene insulated, product
Mechanical performance and heat resistance;In insulated wire cores stranding using the filling of the mineral wool rope of extremely difficult burning and low-smoke bittern-free highly fire-proof packet
With wrapped, the roundness of cable is effectively ensured and has improved low smoke and zero halogen, fire-retardant characteristic.Using the compound resistance of water-swellable
Water band bilayer is wrapped, and every layer of cap rate is not less than 30%, ensures that cable often locates waterstop and is not less than 2 layers.Moisture can effectively be prevented
Along the vertical migration in cable gap.Using Halogen glass fiber tape it is wrapped with extrude halogen-free and low-smoke flame-retardant polyolefin sheathed be used in combination
Structure, further improve cable under flame condition insulating outer layer structure at charcoal, shelling performance, ensure that cable by
Mechanical shock remains to play good protection, cable is made to continue to work normally under water spray double action.The utility model knot
Structure has good flexibility, and excellent electrical property, flame retardant property, water resistance and physical mechanical property are primarily adapted for use in sky
Between relative closure, ground humidity, the subway of personnel's Relatively centralized, tunnel occasion.
Description of the drawings
Fig. 1 is the cross-sectional view of the structure of the utility model;
In figure:1- insulated wire cores, 11- conductors, the crosslinked polyetylene insulated layers of 12-, 2- low-smoke non-halogen flame-retardant bands wrapping layer, 3-
Block water wrapping layer, the compound waterstop of the second intumescents of 4- of the compound waterstop of first intumescent blocks water wrapping layer, 5- Halogen glass fibers

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of extraordinary soft power cable in novel subway tunnel, including cable core, on the outside of the cable core according to
Secondary setting low-smoke non-halogen flame-retardant band wrapping layer 2, the compound waterstop of the first water-swellable block water wrapping layer 3, the second water-swellable
The compound waterstop of type blocks water wrapping layer 4, Halogen glass fiber belt around the cladding 5 and halogen-free and low-smoke flame-retardant polyolefin external sheath layer 6.Cable
Core is made of three groups of insulated wire cores 1 and filled layer 7, and the insulated wire cores are made of conductor 11 and crosslinked polyetylene insulated layer 12.
Conductor 11 meets the 5th kind of plating metal as defined in GB/T3956-2008 or not the annealing copper conductor of metal cladding using selection.
It is wrapped using the filling of the mineral wool rope of extremely difficult burning and low-smoke bittern-free highly fire-proof band in insulated wire cores stranding, effectively
It ensure that the roundness of cable and improve low smoke and zero halogen, fire-retardant characteristic.Using the compound waterstop bilayer of water-swellable around
Packet, every layer of cap rate are not less than 30%, ensure that cable often locates waterstop and is not less than 2 layers.
Using Halogen glass fiber tape wrapped 5 with halogen-free and low-smoke flame-retardant polyolefin sheathed 6 and with structure, further improve
Cable under flame condition insulating outer layer structure at charcoal, shelling performance, ensure that cable by mechanical shock and water spray
Under double action, remains to play good protection, cable is made to continue to work normally.
