Certainly the problems in background technique.
In order to solve the above-mentioned technical problem, a kind of the technical solution of the utility model are as follows: household electric that environment-friendly and green is fire-retardant
Line, including core, the core are made of centrally located several conductors with the insulation sleeve for being socketed in conductor periphery, the core
There are four altogether, it is socketed with copper metal shielded layer on the outside of four cores, is provided between the copper metal shielded layer and core
Filling block, the copper metal shielded layer outside are socketed with instlated tubular, and the instlated tubular is internally provided with hollow sandwich, described heat-insulated
Tube outer surface is connected with separation layer by polyester filled layer, and the separation layer is internally provided with aluminium hydroxide and magnesium hydroxide, institute
It states and is connected between separation layer and instlated tubular by several fiberglass tubes, the fiberglass tubes self-isolation layer extends to the hollow folder of instlated tubular
In layer, and the outer surface of separation layer is provided with PVC oversheath.
As the utility model a preferred technical solution, several fiberglass tubes are with the center of circle of copper metal shielded layer
Center is radially evenly distributed on inside polyester filled layer.
It is tangent two-by-two between four cores as the utility model a preferred technical solution, and in four lines
Center-filled part is provided among core.
As the utility model a preferred technical solution, the filling block is equal with core quantity, and filling block with
Core is staggered.
As the utility model a preferred technical solution, the instlated tubular is using glass fiber material.
By adopting the above technical scheme, by setting hollow sandwich and separation layer, good heat-blocking action can be played, is cooperated
Aluminium hydroxide and magnesium hydroxide, the two is decomposed when by high temperature generates water, plays the role of cooling, high temperature is avoided to influence inner wire
The electric property of core has good anti-flammability.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of household electric wire that environment-friendly and green is fire-retardant, including
Core 1, the core 1 are made of centrally located several conductors 2 with the insulation sleeve 3 for being socketed in 2 periphery of conductor, the core 1
There are four altogether, it is socketed with copper metal shielded layer 4 in the outside of four cores 1, is set between the copper metal shielded layer 4 and core 1
It is equipped with filling block 5, instlated tubular 6 is socketed on the outside of the copper metal shielded layer 4, the instlated tubular 6 is internally provided with hollow sandwich
7,6 outer surface of instlated tubular is connected with separation layer 9 by polyester filled layer 8, and the separation layer 9 is internally provided with aluminium hydroxide
10 and magnesium hydroxide 11, connected between the separation layer 9 and instlated tubular 6 by several fiberglass tubes 12, the fiberglass tubes 12 from every
Absciss layer 9 extends in the hollow sandwich 7 of instlated tubular 6, and the outer surface of separation layer 9 is provided with PVC oversheath 13.
Preferably, several fiberglass tubes 12 are radially uniformly distributed centered on the center of circle of copper metal shielded layer 4
