Description
Technical field
The utility model is related to a kind of cable more particularly to a kind of low-voltage cables.
Background technology
Low-voltage cable is one kind of power cable, is applied to the major trunk roads of power transmission more, and staff is carrying out cable
When being laid with work, it is easy to spoil oversheath in laid processes, to leave hidden danger to safety, lead to that accident occurs.It is existing
In technology, most of the insulation of cable and sheath are formed using plastics and rubber organic polymer, their general wearabilities compared with
Difference.
Meanwhile general insulated aluminum wire does not block water, cable water inlet can have a significant impact to the electrical property of cable, if electric
The water inlet of cable conductor can then cause into after the water vapor of cable, lead to the major accidents such as electric cable explosion.And when fire, flame can edge
Cable sprawling, while also will produce a large amount of smog and toxic corrosive gas.Smog and poisonous gas are often to people
First generate harm.Along the speed of cable sprawling when in order to reduce flame combustion, usually it is added in cable material various fire-retardant
Additive, various types of fire proofings and flame retardant cable is made.
Utility model content
The utility model is mainly solving the technical problems that provide that a kind of anti-pressure ability is strong, reliability is high, water proofing property and resistance
Combustion property height, low-voltage cable easy to use.
In order to solve the above technical problems, a kind of low-voltage cable of the utility model, including more cable cores, the cable core point
It is distributed in the chamber between interlayer and insulating layer, cable core is arranged to twisted pair in the chamber, and the interlayer, which is equipped with, limits cable
The wall of core, the every outer layer of cable core are covered with copper strip shielding layer, and filled layer, the insulation are equipped between the interlayer and insulating layer
The outside of layer is coated with elastic cord breaker, and the outside of the elastic cord breaker is coated with waterproof layer, the external packet of the waterproof layer
It is covered with flame-retardant layer, the outside of the flame-retardant layer is coated with steel-tape armouring layer, and the outside of the steel-tape armouring layer is coated with sheath, institute
It states sheath inner homogeneous and sensing fiber is distributed with.
Further, the cable core is twisted line conductor.
Further, the filled layer opens net polypropylene tearing material to be non-.
Further, the elastic cord breaker includes buffer layer one and buffer layer two, if being provided between the buffer layer
Dry gas capsule.
The beneficial effects of the utility model：1）Interlayer is set between twisted pair, prevents the movement and crosstalk of strand pair；2）Bullet
Property buffer layer can effectively buffer from extraneous pressure, protect cable core without damage well；3）Waterproof layer and flame-retardant layer
So that water proofing property and anti-flammability is greatly improved, preferably protects cable core；4）Every cable core is cladded with shielded layer, and anti-interference intensity is high；
5）The outside of inner sheath is coated with steel-tape armouring layer, and armouring is firm, and tensile strength is big；6）It is fine that sensing is distributed in sheath inner homogeneous
Dimension can find sheath breakage in time.

Specific implementation mode
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of low-voltage cable, including six roots of sensation cable core 1, the cable core 1 be distributed in interlayer 4 and insulating layer 5 it
Between chamber in, cable core 1 is arranged to twisted pair in the chamber, and the interlayer 4 is equipped with the wall for limiting cable core 1, prevents from twisting pair
Movement and crosstalk, 1 outer layer of every cable core is covered with copper strip shielding layer 2, and anti-interference intensity is high, the interlayer 4 and insulating layer 5
Between be equipped with filled layer 3, the outside of the insulating layer 5 is coated with elastic cord breaker 6, and the elastic cord breaker 6 can be effective
It buffering from extraneous pressure, protects cable core without damage well, the outside of the elastic cord breaker 6 is coated with waterproof layer 7,
The outside of the waterproof layer 7 is coated with flame-retardant layer 8, and waterproof layer 7 and flame-retardant layer 8 make water proofing property and anti-flammability greatly improve, more preferably
Protection cable core, the outside of the flame-retardant layer 8 is coated with steel-tape armouring layer 9, and armouring is firm, and tensile strength is big, the steel band armour
The outside of dress layer 9 is coated with sheath 10, and sensing fiber 11 is distributed in 10 inner homogeneous of the sheath, can find sheath 10 in time
It is damaged.
The cable core 1 is twisted line conductor；The filled layer 3 opens net polypropylene tearing material to be non-；The elastic buffer
Layer 6 includes two 6-2 of one 6-1 of buffer layer and buffer layer, and several air bag 6-3 are provided between the buffer layer.
