Abstract
The utility model discloses a kind of soft type low pressure aerial cables, ecto-entad is followed successively by restrictive coating (6), belting layer (5), it is multiple conductors (1) and steel wire (2) in the belting layer (5), is provided with filling (4) between the conductor (1) and steel wire (2)；Using soft circle aluminium wire material synnema at strand, every layer of strand is identical as synnema direction to be twisted the conductor (1)；The steel wire (2) uses phosphating steel wire material；Insulation is provided with outside the conductor (1) and steel wire (2)；Conductor and steel wire outer cladding high resiliency insulating layer guarantee the bending property of core and steel wire, coat the steel wire and insulated wire cores twisted synthesizing cable of insulation, steel wire both plays the role of supporting core, the relatively straight steel wire put of bending property also has improvement, in the case where cable core waves, also solves the problems in stress collection between steel wire and core.
Description
Technical field
The utility model relates to a kind of cable, specifically a kind of soft type low pressure aerial cable belongs to cable manufacturing techniques
Field.
Background technique
Currently, mostly using aerial cable in the old electric network reconstruction in city.Special old city residential block, road are narrow
It is narrow, there is great test to the aerial cable pliability of laying.Aerial cable conductor generally using press round twisted copper,
Aluminum steel and aluminium alloy conductor material, this conductor hardness is big, so that the bending radius of cable is larger, is unfavorable for laying and electrical dress
The installation and use of the specific environments such as spare.It is all directly put using naked steel wire to support entire cable, to cable substantially in the market
Bending degree is also accordingly reduced, and is directly contacted between steel wire and core, in case of motion, is answered between steel wire and core
Power is concentrated, and steel wire is highly vulnerable to breakage insulating layer.
Utility model content
The purpose of the utility model is to provide a kind of soft type low pressure aerial cable, which has preferable bendability
Energy.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of soft type low pressure aerial cable, ecto-entad are followed successively by restrictive coating, belting layer, are multiple in the belting layer
Conductor and steel wire are provided with filling between the conductor and steel wire；The conductor using soft circle aluminium wire material synnema at strand,
Every layer of strand is identical as synnema direction to be twisted；The steel wire uses phosphating steel wire material；It is all provided with outside the conductor and steel wire
It is equipped with insulation.
The insulation is extruded using high resiliency, weatherability polyvinyl chloride material.
The filling uses polypropylene mesh split fibre rope material.
The belting layer is using CPP band or non-woven fabrics is wrapped forms.
The restrictive coating is extruded using high resiliency, weatherability polyvinyl chloride material.
The utility model solves and normally laying installation and steel wire cannot destroy insulation because cable bend degree is insufficient
The problem of.Conductor is twisted by synnema at strand, every layer of strand and the synnema same direction using soft circle aluminium wire, diameter 0.5mm
It closing, this conductor is more soft, significantly reduces to the permission bending radius of cable, and aluminium wire density is small, and it is light-weight, using phosphatization
Steel wire support, the relatively small tensile strength that but can achieve requirement of phosphating steel wire diameter, good bending property can carry out large span
Aerial transmission.Conductor and steel wire outer cladding high resiliency insulating layer guarantee the bending property of core and steel wire, coat the steel wire of insulation
With insulated wire cores twisted synthesizing cable, steel wire both plays the role of supporting core, and the relatively straight steel wire put of bending property also has improvement,
In the case where cable core waves, also solves the problems in stress collection between steel wire and core.Filling makes cable rounding, uses band
Tighten, then squeeze out high resiliency restrictive coating on cable core, in situation in need, buried-pipe laying can also be carried out, facilitate construction and
Save resource.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, a kind of soft type low pressure aerial cable, ecto-entad is followed successively by restrictive coating 6, belting layer 5, the packet
It is multiple conductors 1 and steel wire 2 in belt 5, is provided with filling 4 between the conductor 1 and steel wire 2.
The conductor 1 is using soft circle aluminium wire, diameter 0.5mm, by synnema at strand, every layer of strand and synnema direction
It is identical to be twisted.
If there is fire resistant requirements, can outside conductor 1 wrapped fire-resistant wrapping tape after wrapped mineral fire resistant materials, stranding；If there is resistance
Combustion requires, and high fire-retardance, high resiliency, weather-proof material may be selected in insulation, sheath.
The steel wire 2 uses phosphating steel wire material.
Insulation 3 is provided with outside the conductor 1 and steel wire 2.The insulation 3 uses high resiliency, weatherability polyvinyl chloride material
Material extrudes.
The filling 4 uses polypropylene mesh split fibre rope material.
The belting layer 5 is using CPP band or non-woven fabrics is wrapped forms.
The restrictive coating 6 is extruded using high resiliency, weatherability polyvinyl chloride material.
Above-described embodiment does not limit the utility model in any way, all by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the protection scope of the utility model.
