Abstract
The utility model discloses a mineral insulating cable which comprises a copper sheath and at least one conductive core sleeved in the copper sheath. Insulating materials are filled in the gap between the conductive core and the copper sheath. The cable is excellent in fireproof, explosion-proof, waterproof, high temperature resistant, corrosion resistant, radiation resistant and electromagnetic interference preventing performances, and is smoke and halogen-free, non-toxic, economical, safe and environmental friendly.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of mineral insulated cable.
Background technology
It is reported in recent years in all kinds of electric fire that cause of China, have more than 60% to be caused by electric wiring (electric wire).The safe fire resistance of cable has caused that people pay attention to more widely.Existing common plastics or rubber-like cable are owing to be subjected to the limitation of aspects such as electric property, mechanical performance, fire-proof and explosion-proof performance or environmental-protecting performance, can not utilize at some special occasions, therefore need a kind of inorganic matter cable of being made by inorganic material of design, increase electric property, mechanical performance, fire-proof and explosion-proof performance and the environmental-protecting performance of cable, to adapt to the needs of some special occasions.
The utility model content
The purpose of this utility model is to provide a kind of mineral insulated cable.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of mineral insulated cable, it comprises copper sheath and at least one conductor wire core, described conductor wire core is sleeved in the copper sheath, and the space between described conductor wire core and the copper sheath is filled with insulating material.
Described copper sheath is wrapped with anticorrosion oversheath.
Described core is one, and the center line of the center line of described conductor wire core and copper sheath coincides.
Described conductor wire core is at least two, and described conductor wire core evenly distributes in copper sheath, and the center line of described conductor wire core parallels with the center line of copper sheath.
Described conductor wire core is the copper core.
Described insulating material is magnesium oxide.
The beneficial effects of the utility model:
(1) fire prevention: because the material of composition and cable all is inorganic matter (copper and magnesium oxide), there is not any combustible medium, still can keep normal power-up in short-term at the melting temperature cable near copper, thereby be that the fire-fighting system level requires the harbor replacement fire-retardant, the tendency product of fire-resistant class cable.
(2) seamless copper pipe sheath and the cable termination that is tightly connected with it can stop flammable oil vapour, imflammable gas and flame to enter the explosion-proof that rises with the electric equipment of cable by cable, are the best guarantees in the explosion-proof performance high request place of oil, chemical industry, colliery, Generators.
(3) waterproof: copper sheath is to be drawn by seamless copper pipe to form, thereby any approach of moisture content thing can enter cable inside, is that the ideal of moist underground such as subway, tunnel is selected.
(4) smokelessly, Halogen, the five poisonous creatures: scorpion, viper, centipede, house lizard, toad: this cable is made up of copper and inorganic matter magnesium oxide, even thereby this product burns in the close flame of the fusing point of temperature and copper, can not produce any smog, halogen or poisonous gas yet, be airport, hospital, station, machine-operated office building etc. public safety require very high place to substitute economy the most, the safety of low smoke, zero halogen, the organic cable of fire-resistant, fire-retardant class, the green product of environmental protection.
(5) high temperature: this cable allows the long-term work temperature can reach 250 ℃, and short time or unusual time allow the melting temperature near copper, far above plastics class " high-temperature cable ", are the optimal selections of high temperature operations such as steel mill, copper work, aluminium manufacturer.
(6) corrosion resistance is strong: copper sheath has stronger corrosion resistance, in some special strong acid or highly basic occasion, can adopt to add the anticorrosion of one deck oversheath.
(7) radiation hardness, anti-electromagnetic interference: this cable is after radiation, and the insulating material resistance value any variation can not take place, and is distribution cable desirable in the nuclear facility.
