Description
Technical field
The present invention relates to a kind of electric wire and make the field, relate in particular to the composition of this cable cover(ing).
Background technology
Termite is one of important pests in the world, is distributed in each continent, especially the torrid zone and subtropical zone.The termite kind is a lot, and is densely distributed, and it is wide to relate to the region.Evil of termite and economic construction, lives and properties all combine, serious harm economic construction and personal safety.Termite causes electric power accident, communication failure to happen occasionally to common cable, therefore required exploitation termite proof cable.
Protection against rodents, anti-ant method mainly are the metallic sheaths that adopts corrugated metalpipe and thin steel band to form in the cable industry at present, or with rigid plastics or fiberglass pipe cable are carried out physical protection, and novel high-strength carbon element pipe was also brought into use in recent years; This infrastructure cost is higher, and finishes in the construction site mostly.
Its model great majority of the termite-proof cable of protection against rodents of using of China are copper core polyvinyl chloride insulation pvc sheath cable present stage in addition, the sheath material of this cable is thermoplastics type's polyvinyl chloride elastic material, though this material has elasticity and flexibility preferably, but, this material is in the granulation processing, must add heavy metal compound such as lead salt as stabilizer, must use Polybrominated biphenyl organic compounds such as (ethers) as plasticizer.A large amount of uses of these materials can make these cables after life cycle is scrapped, and its cable waste processing meeting causes severe contamination to environment; And this model cable is after coming into operation, under contingency breaking out of fire situation, can contain toxic gases such as halogen in the gas of its burning, human body can cause death by suffocation in very short time after sucking these toxic gases, reduced personnel escape's chance in the fire.In addition,, can cause corrosion, produce the fire quadratic loss building, equipment, instrument etc. owing to contain corrosive gas such as halogen.
Summary of the invention
The technical issues that need to address of the present invention have provided the termite-proof LSOH anti-flaming fireproof power cable of a kind of environment protection, rat, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
