The anticorrosive cable of a kind of waterproof
Technical field
The utility model relates to cable technology field, relates in particular to the anticorrosive cable of a kind of waterproof.
Background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and often round Yi Gen center, be twisted into, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all comprised of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.
The kind of cable is divided into fire-retardant Plastic-sheathed Cable, core level cable, bare wire and bare conductor goods, power cable, communication cable and optical fiber, electromagnetic wire, flexible fire-proof cable etc.Water resistance is to consider an important indicator of cable; because moisture is very harmful to cable; if there is moisture to immerse, will cause conductor oxidation, increased the energy loss of transmission line, but cable inevitably be used in high drop place; the moister place of environment particularly; long-time use, water infiltration is can hardly be avoided, and cable is due to frequent movement; often there will be the quality problems such as sheath cracking, disconnected core, can not meet people's user demand.
Summary of the invention
The purpose of this utility model is to provide the anticorrosive cable of a kind of waterproof, its reasonable in design, profile is soft, there is heat-resisting, cold-resistant, acid and alkali-resistance and corrosion resistance gas, good water-proof effect, under high temperature, high and cold environment, electric property is stable, ageing resistace is outstanding, convenient mobile, can use for a long time, met people's user demand.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is comprised of conductor 1, insulating layer of conductor 2, glass polyester belt 3, cable core 4, insulation screen 5, semi-conductor electricity water blocking layer 6, proof copper-wire braided screen 7, methyl silicate water blocking layer 8, metal armouring layer 9, silicon rubber oversheath 10, cable core 4 is to form by several cores are stranded, core is comprised of conductor 1 and the insulating layer of conductor 2 that is coated on conductor 1 outside, the outer setting of insulating layer of conductor 2 has glass polyester belt 3, the outer setting of cable core 4 has insulation screen 5, the outer setting of insulation screen 5 has semi-conductor electricity water blocking layer 6, the outer setting of semi-conductor electricity water blocking layer 6 has proof copper-wire braided screen 7, the outer setting of proof copper-wire braided screen 7 has methyl silicate water blocking layer 8, the outer setting of methyl silicate water blocking layer 8 has several metal armouring layers 9, the outer setting of metal armouring layer 9 has silicon rubber oversheath 10.
Described glass polyester belt 3 is the composite beds that combined by glass fibre belt and polyester belt.
Described metal armouring layer 9 adopts galvanized steel material to make, and galvanized steel material has the characteristics such as good waterproof, anticorrosion and high strength, realizes waterproof anti-corrosion function.
Described silicon rubber oversheath 10 is anticorrosion butyronitrile soft elastomer sheath.
The utility model reasonable in design, profile is soft, has heat-resisting, cold-resistant, acid and alkali-resistance and corrosion resistance gas, good water-proof effect, under high temperature, high and cold environment, electric property is stable, and ageing resistace is outstanding, convenient mobile, can use for a long time, met people's user demand.
