Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of rated voltage 66/110KV copper strip shielding and block water electric power electricity
Cable.
Background technology
The application history of existing thirties years of domestic crosslinked polyethylene (XLPE) insulated power cable, because it is good
Electrically and mechanically physical property, and have that production technology is simple, portable construction, transmission capacity big, mounting and installation and maintaining
Conveniently, not by advantages such as drop are limited, it is widely used in power system.
Along with people are to cable insulation water suction and the research of water tree and the intensification of understanding, there is a growing awareness that water proofing property
Can be to the importance of power cable with cross-linked polyethylene insulation, according to statistics, in domestic electrical network 10 35 kV power system, underground is straight
Bury XLPE insulated cable and there is no employing stop water, generally after running 8～12 years, grow a large amount of water tree,
There is breakdown accident, have a strong impact on the safe operation of electrical network.Therefore, cable blocks water technology for ensureing the reliable of XLPE cable
Property all had very important significance with the life-span.Or long-term area of heavy rainfull higher in level of ground water (on the south such as China the Changjiang river
District), increasing user proposes the requirement blocked water to cable.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that a kind of multiple block water, anti-side pressure is strong, shield effectiveness good,
Corrosion resistant rated voltage 66/110KV copper strip shielding water-resistant power cable.
For achieving the above object, the present invention provides rated voltage 66/110KV copper strip shielding water-resistant power cable, including absolutely
Edge core, outer around semiconductor waterstop of double-baging in insulated wire cores, outer around copper strips of double-baging in semiconductor waterstop, outside copper strips
First the wrapped semiconductive buffer strip that blocks water is further around bag semiconductor waterstop, extrudes corrugated aluminum sheath, in wrinkle outside semiconductor waterstop
Coating bitumen layer outside stricture of vagina aluminium sheath, finally the outermost layer at cable extrudes high-density polyethylene outer sheath.
Preferably, described insulated wire cores is by conductor, around the semiconductive nylon tape wrapped in outside conductor and three-layer co-extruded half
Conductor shield outside electroconductive nylon band, insulating barrier, insulation screen are constituted.
Preferably, semiconductive graphite linings is also coated outside described high-density polyethylene outer sheath.
The beneficial effects of the present invention is:
Compared with prior art, present invention employs that core blocks water, cable core blocks water, the multiple stop water such as block water outside cable core, no
Only can effectively prevent steam from entering inside cable, it is simply that rainwater weather, water all cannot be introduced in cable, thus extends cable
Service life；Construction of cable symmetrical balance, can eliminate the pulse voltage impact on cable insulation, prevent insulating barrier breakdown；Electricity
The metal screen layer of cable, can use as the neutral conductor again, save material cost；Wherein, corrugated aluminum sheath bears cable
Short circuit current, the most waterproof and bear the effect of anti-side pressure；The eddy current effect that copper strips produces for the alibate that smoothes away wrinkles；
The outer wrapped semiconductive nylon tape of conductor, not only acts as shielding action and also acts as buffer action, and serve double with conductor shield
Heavily shield；Cable outermost layer coating graphite so that cable has good heat conductivity and electric conductivity, high temperature resistant, thermal shock resistance
Good, good lubricity, plasticity, corrosion resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As it is shown in figure 1, the present invention provides a kind of rated voltage 66/110KV copper strip shielding water-resistant power cable, including insulation
Core, this described insulated wire cores is by conductor 1, around the semiconductive nylon tape 2 wrapped in outside conductor and three-layer co-extruded semiconductive Buddhist nun
Conductor shield 3 outside tengential belt, insulating barrier 4, insulation screen 5 are constituted；
Then, outer around semiconductor waterstop 6 of double-baging in insulated wire cores, outer around copper strips 7 of double-baging in semiconductor waterstop, at copper
The outer first wrapped semiconductive of the band buffer strip 8 that blocks water, further around bag semiconductor waterstop 9, extrudes corrugated aluminum sheath outside semiconductor waterstop
10, outside corrugated aluminum sheath, coat bitumen layer 11 so that cable has good anti-corrosive properties, and finally the outermost layer at cable extrudes
High-density polyethylene outer sheath 12, also coats semiconductive graphite linings 13 outside high-density polyethylene outer sheath.
The above is only the preferred embodiment of the present invention, it is noted that come for those of ordinary skill in the art
Saying, under the premise without departing from the principles of the invention, it is also possible to make some modification and improvement, these also should be regarded as belonging to the present invention
Protection domain.
