Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of low smoke and low halogen and resist cold
CABLE MATERIALS, preparation method and cable cover(ing).
Background technology
In recent years, the Cultivar development of electric wire presents diversified trend, from list
Pure electric power transfer function, to multi-functional transformation, is i.e. attached according to different purposes respectively
New characteristic, such as: low smoke and zero halogen, low-smoke low-halogen, cold-resistant, waterproof, protection against rodents, anti-
Coptotermes formosanus Shtrari. etc., at some special occasions, even need cable to possess more than two or more
Overall characteristic.
The reinforcement year by year Cable Firing Accident recognized along with people, the fire-retardant problem of cable
Also receive much concern.The halogen gas burst size that produces when general flame retardant cable burns by it and
The amount of being fuming can be divided into flame retardant cable, low bittern type flame-retarded cable, low smoke and low halogen type cable and nothing
Halogen low cigarette type cable.And at the extremely frigid zones such as northern China and western part, winter temperature is low,
Time length, day and night temperature are big, and in recent years, numerous clients increase in the technical protocol of cable
Add cold-resistant requirement.Saxophone is smooth, Uzbekistan, Kirghizstan, Tadzhikistan
The country of Central Asia such as Si Tan, usually require that power cable must meet Russian standard, this standard
In be distinctly claimed cable and need possess cold tolerance.Therefore in some of these extremely frigid zones
Important place (such as subway, airport, skyscraper etc.), it is necessary to use and be provided simultaneously with
Cold tolerance and the cable of fire-retardant (or low-smoke low-halogen, low smoke and zero halogen) performance.
Abroad, Kazakhstan, Uzbekistan, Kirghizstan, Ta Ji
The countries and regions such as Bolkestein and External Mongolia are the most relatively long for winter time, and minimum temperature
Relatively low.Such as Kazakhstan, minimum temperature reaches-40～-50 DEG C, and Kirghizstan is
Low temperature-39 DEG C, Uzbekistan's minimum temperature-38 DEG C ,-40 DEG C of External Mongolia.Equally,
At home, the northern province of such as Xinjiang, Gansu, Ningxia is also that winter time is long, and temperature is relatively
Low.Such as Xinjiang minimum temperature-40 DEG C, Ningxia minimum temperature-33 DEG C, Shanxi minimum temperature
-28 DEG C, some areas minimum temperature reaches-44.8 DEG C.The cable cryogenic property in these areas
Require the highest, the cable laid the most out of doors, it has to be possible to bear-30 DEG C ,-40 DEG C
Or the low temperature of-50 DEG C, otherwise cable jacket it is possible at low temperatures embrittlement rupture, thus
In the service life of serious curtailment cable, affect the regular supply of electric power, and according to state of China
The cable of family's standard production can only ensure normally to use at-15 DEG C.
Client's clear stipulaties cable in cable technology requires must possess low smoke and low halogen
And tolerance to cold, wherein low smoke and low halogen should meet IEC 60332-3Category A,
Cold-resistant index should meet minimum operating temperature-50 DEG C, and when temperature is not less than-15 ° of С
Without preheating i.e. laying installation.As can be seen here, cold-resistant class cable is had been presented for more by client
High requirement.Sales volume by current Xin Lan factory cold resistant cable, it is contemplated that 3-5% will be brought
Profit growth point.
From the point of view of the whole world, polrvinyl chloride (PVC) because it is cheap, superior performance,
Insulation and sheath material as electric wire use in a large number.The most common low pressure is gathered
Vinyl chloride insulation and protective case wire cable remain the cable that usage amount is the biggest, almost account for
More than the 70% of electric wire consumption, and polrvinyl chloride is used as electric wire and cable jacket,
Communication cable, high-low pressure power cable, instrument and meter and control cable, account for 90%
Above.But halogen-containing materials can be discharged during PVC burning, corrosive gas hydrogen chloride and
Other poisonous black smoke, seriously jeopardizes the life security of people, corrosion instrument and instrument facility
Deng.Some densely populated Code in Hazardous Special Locations such as grade in developed country and flourishing city are in plain text
Regulation uses low cigarette, bittern-free flame-proof material, but some less developed countries and area still use
Common PVC flame-proof material can only achieve fire-retardant requirement and cannot reach low cigarette, low simultaneously
Halogen, simply just needs in the densely populated PVC insulation waiting Code in Hazardous Special Locations to use and jacketed cable
Want fire-retardant while reach low cigarette, low halogen.At the cold district near south poles, use
PVC cable will there is a problem in that the cold tolerance of igelite is poor,
Easily there is the phenomenon such as embrittlement, cracking in the condition less than-30 DEG C.The cold tolerance of polrvinyl chloride
Far below polyethylene (including crosslinked polyethylene), silicone rubber and fluoroplastics, so low
Pvc sheath cable is used to be easy to interruption of service under the conditions of temperature, and at this
Under the conditions of Zhong can not this type of cable of laying installation, it can be to the special engineering of winter construction
Project brings the biggest difficulty.Although at present individually there is low cigarette, low halogen fire-retardancy or list
Unique have the cable of tolerance to cold the most generally, but have low cigarette, low halogen fire-retardancy simultaneously
Also cannot be able to prepare with the cable of tolerance to cold.
Summary of the invention
