Description
Technical field
The utility model is related to a kind of field of cable technology more particularly to a kind of low-smoke non-halogen flame-retardants and fire resisting photovoltaic electric
Cable.
Background technology
In current industrialization society, the energy and information are the social big pillar of amount, whether electric energy or information
Transmission all be unable to do without electric wire, particularly commerce and trade building, subway, tunnel and nuclear power station etc..At present, cable is pole in the market
Incendive object, when burning, easily generate substantial amounts of poisonous and hazardous corrosive gas and dense smoke, cause second of disaster, therefore
And environmental-protecting performance is bad；Because fire resistance is bad, easily open circuit after burning, it is impossible to the effective lives and properties peace for ensureing citizen
Entirely.In order to which disaster is preferably minimized, so reach the requirement of fire prevention and environmental protection with low-smoke non-halogen flame-retardant and fire-resistant wire and cable.
Domestic market fire prevention cable quality is irregular, and fire is caused to take place frequently, seriously affects people’s lives quality.
It is accordingly required in particular to a kind of low-smoke non-halogen flame-retardant and fire resisting photovoltaic cable, above-mentioned existing to solve the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of low-smoke non-halogen flame-retardant and fire resisting photovoltaic cable, to solve the prior art
Present in fire prevention and environment-friendly electric wire cable it is off quality, cause fire, the safety of life and property for influencing people is asked
Topic.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of low-smoke non-halogen flame-retardant and fire resisting photovoltaic cable, which is characterized in that it includes conductor, flame retardant coating, insulating layer, shield
Jacket layer, the conductor are twisted by multiply copper-clad aluminum conductor；Flame retardant coating is closely coated around the conductor；The flame retardant coating four
Insulating layer made of all close cladding halogen-free low-smoke flame retardant materials；The insulating layer surrounding closely coats halogen-free low-smoke flame retardant material
Manufactured restrictive coating；Talcum powder is filled between the insulating layer and the restrictive coating.
In one embodiment of the utility model, the low-smoke non-halogen flame-retardant and fire resisting photovoltaic cable, feature exist
In conductor is twisted using the copper clad aluminum of 56 a diameter of 0.29mm.

Demonstrate,prove product have it is good electrically and mechanical performance.
Flame retardant coating 2 is closely coated around conductor 1；Flame retardant coating 2 is inorganic mineral insulation material, the Duplication of flame retardant coating >=
30%.
2 surrounding of flame retardant coating closely coats insulating layer 3 made of halogen-free low-smoke flame retardant material；Insulating layer 3 is low for cross-linking radiation
Cigarette bittern-free flame-proof material.It is mainly low cigarette, Halogen, fire-retardant, high temperature resistant that it, which is acted on, so as to reach the requirement of environmental protection.
Insulating layer surrounding closely coats restrictive coating 4 made of halogen-free low-smoke flame retardant material；Restrictive coating 4 is the low cigarette of cross-linking radiation
Bittern-free flame-proof material.It is mainly low cigarette, Halogen, fire-retardant, high temperature resistant that it, which is acted on, so as to reach the requirement of environmental protection.
Filled with a little talcum powder between insulating layer 3 and restrictive coating 4, prevent from sticking in one between insulating layer 3 and restrictive coating 4
It rises, insulating layer 3 can be made to be easily peeled off out with restrictive coating 4.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
