Background technology
Salt is a kind of very important industrial chemicals, it also is one of people's necessity of living, China has many inland lakes, wherein the salt content of quite a few inland lake is very high, salt lake, Xinjiang for example, Inner Mongol Alxa, Qinghai Lake, Yuncheng, Shanxi, Nam Co Basin in Tibet or the like inland lake, the coastline that adds China is extremely long, the for example Shandong in Bohai Sea Gulf and Jiangsu, Fujian, Guangdong, the large enterprise that vast coastal province ,city and area such as Guangxi and Hainan is engaged in salt manufacturing or salt chemical engineering is a lot of, but there is same problem in they: as the service cable of electric energy transmitting, owing to adopt the floating drum supporting way, lake surface or seawater top is laid in, cable surface is easy to salt crust, and can tie thicker and thicker, cable be corroded in the not only corresponding deadweight that increases cable easily, and influence cable heat radiation, useful life that final its consequence can only reduce the ampacity and the cable of cable conductor, moreover in order not increase the deadweight of cable, present cable all is single core.
Summary of the invention
The purpose of this invention is to provide the ethylene propylene rubber insulated non-stick sheath electrical flexible cable that a kind of electric pressure reaches 10kV, this cable has good flexibility, sheath has good waterproof and prevents surperficial salt crust performance, is suitable for the basic routing line of salt manufacturing Hu Haidiqu as electric energy transmitting.
For realizing above purpose, technical scheme of the present invention provides a kind of rated voltage 10kV ethylene propylene rubber insulated non-stick sheath electrical flexible cable, comprise conductor, A semiconductive nylon tape, conductor shield, rubber insulation, insulation screen, B semiconductive nylon tape, C semiconductive nylon tape, inner sheath, waterstop and oversheath, conductor is provided with A semiconductive nylon tape outward, be provided with conductor shield between A semiconductive nylon tape and the rubber insulation, between rubber insulation and B semiconductive nylon tape, be provided with insulation screen, insulation screen is outward by B semiconductive nylon tape, C semiconductive nylon tape is provided with inner sheath, inner sheath is outer to be provided with oversheath by waterstop, it is characterized in that, between B semiconductive nylon tape and C semiconductive nylon tape, be provided with zinc-plated soft copper silk woven shield, be provided with the nylon yarn woven shield between inner sheath and waterstop, described oversheath is the chlorosulfonated polyethylene rubber oversheath that mixes the fusibleness polytetrafluoroethylene.
Described conductor 1 is closed by many zinc-plated annealed copper skein silks and forms; Described conductor shield is a semiconductive ethylene-propylene rubber layer; Described rubber insulation is the ethylene propylene diene rubber insulating barrier, insulating material adopt than the plastic insulation softness the ethylene propylene diene rubber Insulation Material of Duoing, during ethylene propylene rubber insulation material is applicable to, lv power cable, its temperature resistant grade and crosslinked polyethylene insulation material are suitable, it is 90 ℃, not only softness but also can bear high voltage, make its become cable that requirement moves first-selected insulating material.
Described insulation screen is the semi-conductive layer of ethene-vinyl acetate EVA copolymer;
Described chlorosulfonated polyethylene rubber is made up of following weight portion raw material:
Chlorosulfonated polyethylene rubber 100 Chlorodimethyl second propionyl ureas 5～8
Antimony oxide 5～7 alkali formula phthalic acid lead 5～7
Calcinated argil 55～65 triallyl cyanates 4～6
N-PA 3～4 vinyl silanes 1～2
High wear-resistant carbon black 75～85 dioctyl phthalates (DCP) 2.5～3
Chlorinated paraffin oil 20 fusibleness polytetrafluoroethylene 1～3.
The present invention adopts metallic shield between B semiconductive nylon tape and C semiconductive nylon tape, cable metal shielding form is the tinned copper wire braid shielded, count reaches 80%, its wrapped one deck semiconductive nylon tape in outside, adopt the high-strength nylon filament to weave, to remedy the relatively poor shortcoming of chlorosulfonated polyethylene rubber sheath machinery strength ratio, overlapping again wrapped one deck insulation waterstop outside the fibrage layer is to improve the water proofing property of cable.
Adopt chlorosulfonated polyethylene rubber oversheath soft, the long-term work temperature can reach 90 ℃, and excellent especially weather-resistant performance is arranged, and is acidproof, alkaline-resisting, can stand erosion and the destruction of various biologies or microbe, and anti-ozone and corona-resistance property are good.And the water absorption of chlorosulfonated polyethylene rubber is very little, even chlorosulfonated polyethylene rubber (CSM) was immersed in the water 2 years, its mechanical property changes all little, meets the requirement that cable should have good water resistance fully.
The adding of fusibleness polytetrafluoroethylene has greatly improved the lubrification of sheath rubber, makes it have good not viscosity and resistance to wear.
Advantage of the present invention be have good flexibility, sheath has good waterproof and prevents surperficial salt crust performance.
Description of drawings
Fig. 1 is a rated voltage 10kV ethylene propylene rubber insulated non-stick sheath electrical soft cable structure schematic diagram.
