Abstract
The utility model relates to a waterproofing type special cable for underground tunnels and light rails, and belongs to the technical field of power transmission cables. Insulation wire cores are arranged in the waterproofing type special cable for underground tunnels and light rails, inner cores of the insulation wire cores are conductive bodies, the outer layer of the insulation wire cores are insulation layers and outer protection layers are arranged outside the insulation wire cores. The utility model is characterized in that the inner cores of the insulation wire cores are the multi-strand conductive bodies; special type composite waterproof layers are arranged between the insulation layers of the insulation wire cores and the outer protection layers. The utility model has excellent waterproof and moistureproof performance. The utility model can be widely used as the waterproofing type special cable for underground tunnels and light.
Description
Technical field
The utility model belongs to power handling cable technical field, particularly relates to a kind of waterproofing type subway tunnel, light rail private cable.
Background technology
Present known subway tunnel, light rail are with there being insulated wire cores in the construction of cable, the inner core of insulated wire cores, skin are insulating barrier, and there is outer jacket the insulated wire cores outside.When this cable uses, owing to have water-proof function or water-proof function not bad,, and cause the insulation property of insulating barrier to reduce or inefficacy usually because of for a long time under wet environment or be immersed in the water and use, produce the electric leakage accident, can not satisfy the normal use of occasions such as subway tunnel, light rail.
Summary of the invention
The utility model provides a kind of waterproofing type subway tunnel, light rail private cable for solving the problem that existing known technology exists.
The purpose of this utility model mainly is to be city underground tunnel, the supporting design specialized cable of light rail.
This cable design has compound water blocking layer, adopt the extruding layer structure of the excellent toughness of waterstop+have, wear-resisting and low permeability material, this cable has improved the comprehensive waterproof ability when laying operation under water environment, can satisfy the requirement that this cable is laid under the wet environment for a long time or is immersed in the harsh environment for use in the water.
The utility model adopts following technical scheme:
A kind of waterproofing type subway tunnel, light rail private cable, there is insulated wire cores inside, the inner core of insulated wire cores is a conductor, skin is an insulating barrier, there is outer jacket the insulated wire cores outside, the inner core that is characterized in insulated wire cores is the multiply flexible conductor, and compound water blocking layer is arranged between the insulating barrier of insulated wire cores and the outer jacket.
The utility model can also be taked following technical measures:
Described waterproofing type subway tunnel, light rail private cable are characterized in that compound water blocking layer is made of waterstop and extruding layer.
Described waterproofing type subway tunnel, light rail private cable are characterized between compound water blocking layer and the outer jacket armour being arranged.
Described waterproofing type subway tunnel, light rail private cable are characterized between extraordinary complex waterproof layer and the armour oxygen barrier layer being arranged.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Wherein, 1-soft copper conductor, 2-insulating barrier, the compound water blocking layer of 3-, 4-oxygen barrier layer, 5-armour, 6-outer jacket.
Advantage that the utlity model has and good effect:
This cable is to be city underground tunnel, the supporting private cable of light rail, owing to adopted technical solutions of the utility model, therefore, compares with common cable, has following characteristics:
1, this cable has excellent waterproof, humidity resistance: improved the comprehensive waterproof ability when this cable lays operation under water environment greatly, can satisfy the requirement that this cable is laid under the wet environment for a long time or is immersed in the harsh environment for use in the water fully.
2, this cable sheath adds efficient and environment-friendly type protection against rodents repellant outer jacket, makes this cable have the mouse bite preventing function.
3, ultraviolet resistance: satisfy GB 14049-93 standard-required.
4, fire resistance: satisfy GB/T 18380.3-2001 bunchy category-A burning test standard-required.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following example now, and conjunction with figs. is described in detail as follows:
