Abstract
The utility model discloses a kind of low-smoke halogen-free inflaming-retarding cables, including more conductor cores, the outside of the every conductor cores to be surrounded with inorganic high-temperature resistant insulating layer；The more conductor cores constitute cable core, and are filled with halogen-free expansion fire retardant in the gap location of cable core；Non-magnetic metal protective sleeve is surrounded on the outside of the cable core；The outer wall of the non-magnetic metal protective sleeve is enclosed with low smoke and zero halogen oversheath.The beneficial effects of the utility model are: by the setting of non-magnetic metal protective sleeve so that in the case of fire, cable core directly burns from flame；The gap location of cable core is filled with halogen-free expansion fire retardant, i.e., can generate volume expansion under the high temperature conditions, which can not only play heat-insulated effect, but also can also play the role of stable conductor cored structure；Inorganic high-temperature resistant insulating layer is surrounded on the outside of conductor cores, inorganic insulation layer can play preferably resistance to fire action, to protect conductor cores.
Description
Technical field
The utility model relates to a kind of cable, in particular to a kind of low-smoke halogen-free inflaming-retarding cable.
Background technique
With the continuous development of science and technology and social economy, safety and environmental protection performance requirement of the people to wire and cable product
It is higher and higher.Traditional halogen cable material can release a large amount of toxic hydrogen halides, the life to personnel in burning
Life safety and Architectural Equipment damage, using also restrained.Thus, the R & D design about low-smoke halogen-free inflaming-retarding cable
Increasingly it is taken seriously.
Low-smoke halogen-free inflaming-retarding cable in the prior art, is usually surrounded with plastic insulating layer on the outside of cable core, due to plastics
Insulating layer easily burns, and when burning generates amount of heat, and causing temperature to steeply rise causes fire-resistant wrapping tape to carbonize, and becomes after charing
Firmly, embrittlement, it is easy to fall off, to lose protective effect, and water leaching can not be born, hit, affect communication, electric power exists
It is safe and smooth under fire condition.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of low-smoke halogen-free inflaming-retarding cables, have good fire-retardant anti-
Fiery function, while cable core has preferable structural stability in the case of fire.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of low-smoke halogen-free inflaming-retarding cable, including more conductor cores, the outside of the every conductor cores are surrounded with inorganic
Temperature-resistant insulation layer；The more conductor cores constitute cable core, and are filled with halogen-free expansion fire retardant in the gap location of cable core；Institute
It states and is surrounded with non-magnetic metal protective sleeve on the outside of cable core；The outer wall of the non-magnetic metal protective sleeve is enclosed with outside low smoke and zero halogen and protects
Set.
Further, the halogen-free expansion fire retardant is made of inorganic siliceous expanding flame-proof material.
Further, the inorganic high-temperature resistant insulating layer by basalt fibre and or glass fibre be made.
Further, the non-magnetic metal protective sleeve is copper sheath.
Further, the corrugated processing of embossing is carried out to the copper sheath.
Further, the conductor cores are formed by several conductor strands.
The beneficial effects of the utility model are:
By the setting of non-magnetic metal protective sleeve so that in the case of fire, cable core directly burns from flame；Cable core
Gap location is filled with halogen-free expansion fire retardant, i.e., can generate volume expansion under the high temperature conditions, which not only can be with
Play the role of heat-insulated effect, and stable conductor cored structure can also be played；Inorganic high-temperature resistant is surrounded on the outside of conductor cores
Insulating layer, inorganic insulation layer can play preferably resistance to fire action, to protect conductor cores.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the utility model.
In figure, 1- conductor cores, 2- inorganic high-temperature resistant insulating layer, 3- halogen-free expansion fire retardant, 4- non-magnetic metal protective sleeve,
5- low smoke and zero halogen oversheath.
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.
As shown in Figure 1, a kind of low-smoke halogen-free inflaming-retarding cable, including more conductor cores 1, the outside of the every conductor cores 1
It is surrounded with inorganic high-temperature resistant insulating layer 2；The more conductor cores 1 constitute cable core, and are filled with Halogen in the gap location of cable core
Expansion type flame retardant 3；In order to guarantee that cable core directly burns from flame, non-magnetic metal protective sleeve is surrounded on the outside of the cable core
4；The outer wall of the generation of cigarette and toxic gas when in order to reduce burning, the non-magnetic metal protective sleeve 4 is enclosed with outside low smoke and zero halogen
Sheath 5.
Specifically, the inorganic high-temperature resistant insulating layer 2 by basalt and or glass fibre be made.Basalt and glass fibers
Dimension is preferable inorganic insulation layer, not only plays the role of fire resisting, but also can protect conductor cores.
Specifically, the halogen-free expansion fire retardant 3 is made of inorganic siliceous expanding flame-proof material, i.e., by inorganic silicon object
Matter is introduced into expansion type flame retardant.Inorganic silicon is chosen as silicon ash, diatomite either attapulgite, expansion type flame retardant and is selected as
Halogen-free type expansion type flame retardant in the prior art.
Specifically, the non-magnetic metal protective sleeve 4 is copper sheath.
Specifically, the flexibility in order to guarantee copper sheath, carries out the corrugated processing of embossing to copper sheath.
Specifically, the conductor cores 1 are formed by several conductor strands.Twisted conductor can increase the flexibility of cable,
And stranded conductor continuous production is preferable.
The action principle of halogen-free expansion fire retardant 3 in the utility model are as follows: it can generate body under the high temperature conditions
Product expansion, has enriched 4 inner space of non-magnetic metal protective sleeve by volume expansion, has secured the relative position of conductor cores 1, thus
So that cable is in the case of fire, structure is more stable, ensure that communication, electric power in case of fire safe and smooth.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
