Description
Technical field
This utility model relates to a kind of low-voltage cable, especially a kind of composite low pressure cable.
Background technology
Traditional low-voltage cable many employings copper conductor is as cable core material, but is to reduce energy consumption, cost-effective, with aluminium alloy
Conductor replaces copper conductor has become trend as cable core material.Compared to copper core cable, aluminium alloy cable good bending property.But
Owing to aluminum alloy materials tensile strength is less than Cu alloy material, so aluminium alloy cable entirety tensile strength is not as copper core cable,
This has placed restrictions on its range of application.
Further, since low-voltage cable is all laid in indoor, just cannot be carried out using if gnawed by Mus ant.
Summary of the invention
For weak point present in the problems referred to above, this utility model is overall anti-after providing one can improve cable cabling
The bending property of tensile strength and cable, and also the composite low pressure cable that cable gnawed by Mus ant can be avoided.
For achieving the above object, this utility model provides a kind of composite low pressure cable, including insulated wire cores (1), optical fiber
Unit (2), glass fibre lapping layer (4), interior insulation sleeve (5) and rat-and-ant proof composite sheath (6), in described insulated wire cores (1), institute
State fiber unit (2) and fire-retardant colloidality implant (3) and be arranged on the inside of described glass fibre lapping layer (4), described rat-and-ant proof
Composite sheath (6) and described interior insulation sleeve (5) are wrapped in the outer surface of described glass fibre lapping layer (4) successively.
Above-mentioned composite low pressure cable, wherein, described fiber unit (2) is by extruding colored optical fiber the most successively
(21), block water filling tape (22), Loose tube (23), non-metal reinforcement member (24) and oversheath (25) composition.
Above-mentioned composite low pressure cable, wherein, outside described insulated wire cores (1) is by copper conductor or aluminium conductor and its
Portion's bag carries out crosslinked polyethylene or polrvinyl chloride composition, and the quantity of described insulated wire cores (1) is at least two.
Above-mentioned composite low pressure cable, wherein, the material of described interior insulation sleeve (5) be low-smoke non-halogen flame-retardant polyethylene or
Low smoke halogen-free flame-retardant polyolefin.
Above-mentioned composite low pressure cable, wherein, is additionally provided with the neutral conductor in the inside of described glass fibre lapping layer (4)
(7), the described neutral conductor by neutral conductor (71) and is extruded in the neutral insulating barrier (72) outside it and constitutes.
Compared with prior art, this utility model has the advantage that
Overall tensile strength and the bending property of cable after can improving cable cabling by fire-retardant colloidality implant；
Owing to being attached with environment protection, rat ant additive in the outside wall surface of protection against rodents mosquito composite sheath, thus reach rat-and-ant proof
Purpose, to avoid this utility model to be gnawed by Mus ant, extend service life of the present utility model；
Owing to being provided with the neutral conductor in the cable, coat of metal can be reduced by the out-of-balance current of three-phase alternating current and be subject to
Heat, increases the current capacity of cable, it is ensured that the safe handling of cable.

Detailed description of the invention
As shown in Figure 1 to Figure 3, this utility model include insulated wire cores 1, fiber unit 2, glass fibre lapping layer 4, interior absolutely
Edge set 5 and rat-and-ant proof composite sheath 6, insulated wire cores 1, fiber unit 2 and fire-retardant colloidality implant 3 be arranged on glass fibre around
The inside of covering 4.Being additionally provided with the neutral conductor 7 in the inside of glass fibre lapping layer 4, the neutral conductor is by neutral conductor 71 and extrudes
Neutral insulating barrier 72 outside it is constituted.
Insulated wire cores 1 is by copper conductor or aluminium conductor and crosslinked polyethylene carried out by its outside bag or polrvinyl chloride forms.
In the present embodiment, the quantity of insulated wire cores 1 is three.
Fiber unit 2 is by extruding colored optical fiber 21, the filling tape 22 that blocks water, Loose tube 23 the most successively, nonmetal adding
Strong part 24 and oversheath 25 are constituted.Fiber unit is designed as said structure makes the mechanical strength of optical fiber be improved and resist
Micro-bend intensity reduces decay.
By being filled in that glass fibre lapping layer 4 is internal and insulated wire cores 1, resistance between fiber unit 2 and the neutral conductor
Combustion colloidality implant is overall tensile strength after can improving cable cabling, and further increases the bending property of cable.
Owing to being provided with the neutral conductor in the cable, coat of metal can be reduced by the out-of-balance current of three-phase alternating current and be subject to
Heat, increases the current capacity of cable, it is ensured that the safe handling of cable.
Interior insulation sleeve 5 and rat-and-ant proof composite sheath 6 are wrapped in the outer surface of glass fibre lapping layer 4 successively.
The material of interior insulation sleeve 5 is low-smoke non-halogen flame-retardant polyethylene or low smoke halogen-free flame-retardant polyolefin.
Owing to being attached with environment protection, rat ant additive in the outside wall surface of protection against rodents mosquito composite sheath, thus reach rat-and-ant proof
Purpose, to avoid this utility model to be gnawed by Mus ant, extend service life of the present utility model.
It is big that this utility model has area coverage, and range is wide, easy-to-install feature；Power supply and communication unit close two
Being one, product has the good mechanical performance such as compact conformation, bending and resistance to compression, and temperature range of operation is wide；Save the material of wiring
Material, greatly reduces the cost of manual maintenance.
These are only preferred embodiment of the present utility model, be merely illustrative for invention, and nonrestrictive.
Those skilled in the art understands, it can be carried out many changes, revise in the spirit and scope that invention claim is limited,
