Abstract
The invention discloses an outer sheath of an electric cable. The outer sheath comprises, by weight, 12-18 parts of basalt fibers, 5-8 parts of glass fibers, 50-80 parts of ethylene propylene diene monomers, 60-68 parts of nitrile rubber, 2-8 parts of silicone oil and 4-8 parts of siloxane. The outer sheath has the advantages that galvanized steel strips and steel wires or copper strips and copper wires do not need to be wound under the effects of the basalt fibers and the glass fibers, accordingly, the outer sheath which is a protective sheath can be prevented from being mechanically damaged, is easy to bend and is simple and convenient when laid, and the manufacturing cost can be reduced.
Description
Technical field
The present invention relates to the equipment that a kind of power transmission and transformation are used, more particularly, to a kind of cable jacket.
Background technology
In power transmission and transformation field, cable is a kind of a kind of mostly important, also most commonly seen transmission facility, and its effect is exactly
Convey electrical current to user.Cable is typically by the stranded similar rope of several or several groups of wires [every group at least two]
Cable, mutually insulated between every group of wire, and be often twisted into round a center, whole outside is surrounded by the covering of high-insulation
Layer.It is erected at aerial more or be contained in underground, the bottom, for telecommunication or power Transmission.
Cable is mainly made up of following 4 parts.1. conducting wire center：Use high conductivity material（Copper or aluminium）Make.According to deposited
If the requirement to cable softness for the use condition, the every line heart may be formed by solid conductor or multiple conducting wires are stranded.2. exhausted
Edge layer：Insulating materials as cable should have a high insulaion resistance, high breakdown field strength, low dielectric loss and low
Dielectric constant.In cable, conventional insulating materials has oil-paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc..Electricity
Cable is often classified with insulating materials, such as oil-impregnated paper insulation cable, polyvinyl chloride cable, twisted polyethylene cable etc..3. sealing shield
Set：Protect protection insulated wire heart from the damage of machinery, moisture, moisture, chemical substance, light etc..For the insulation of moisture-sensitive, typically adopt
With lead or aluminium extrusion sealing sheath.4. protect cover layer：In order to protect sealing sheath from mechanical damage.Typically adopt galvanized steel
Band, steel wire or copper strips, copper wire etc. surround outside sheath as armor（Claim armored cable）, armor plays electric field shielding and anti-simultaneously
The only effect of external electromagnetic wave interference.In order to avoid steel band, steel wire are corroded by surrounding media, outside them, typically it is coated with drip
Green grass or young crops or wrapping macerated jute layer or extruded polyethylene, polyvinyl chloride set.
If the oversheath of existing cable（Protection cover layer）Need to make using galvanized steel strip, steel wire or copper strips, copper wire etc.
Surround outside sheath although sealing sheath can be protected from mechanical damage for armor, but improve the weight of cable, and
Not pliable, more time-consuming during laying cable, the galvanized steel strip of increase, steel wire or copper strips, copper wire etc. improve oversheath
Cost.
Content of the invention
In order to overcome existing cable oversheath due to being wound around galvanized steel strip, steel wire or copper strips outside sheath and copper wire brings
Not pliable, the defect that laying is wasted time and energy and cost increases, the invention provides a kind of cable jacket, this cable jacket
Do not need to be wound around galvanized steel strip, steel wire or copper strips and copper wire, protective case also can be prevented mechanically damaged it is easy to bending, lay
When simple and convenient, and reduce manufacturing cost.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of cable jacket it is characterised in that：Including following composition in terms of parts by weight：
12～18 parts of basalt fibre
5～8 parts of glass fibre
50～80 parts of ethylene propylene diene rubber

4～6 parts of silicone oil
6～8 parts of siloxanes.
Described cable jacket includes following composition in terms of parts by weight：
16 parts of basalt fibre
7 parts of glass fibre
64 parts of ethylene propylene diene rubber
66 parts of nitrile rubber
4 parts of silicone oil
7 parts of siloxanes.
Described cable jacket also includes 5～12 parts of copper sheet.
It is pungent that described cable jacket also includes 8～12 parts of carbon blacks, 1～3 part of antioxidant, 1～4 part of phthalic acid two
Ester.
The length of described basalt fibre is 5～12mm, and the length of glass fibre is 4～8mm.
The area of described copper sheet is in 12～20mm2.
Compared with prior art, the invention has the advantages that：
1st, the present invention passes through basalt fibre, glass fibre, ethylene propylene diene rubber, the mixing of nitrile rubber, silicone oil and siloxanes
Make the oversheath of cable, by the effect of basalt fibre and glass fibre, instead of the galvanized steel strip being wrapped in outside sheath,
Steel wire or copper strips and copper wire, it is to avoid oversheath is mechanically damaged, because oversheath is not wound around galvanized steel strip, steel wire or copper strips
And copper wire, also it is unaffected it is easy to bend in bending, also just convenient simple during laying cable, production cost
Will reduce.
2nd, cable jacket of the present invention also includes 5～12 parts of copper sheet, and the purpose adding copper sheet is to play electric field shielding
With the effect preventing external electromagnetic wave interference.
3rd, the length of basalt fibre of the present invention is 5～12mm, and the length of glass fibre is 4～8mm, the face of described copper sheet
Amass in 12～20mm2Both ensure that the intensity of oversheath, again will not be mechanically damaged, copper sheet can also play electric field shielding and prevent
The only effect of external electromagnetic wave interference.
