Abstract
The utility model discloses a high temperature and high voltage resistance aluminum alloy cable including a cable core. The cable core includes a plurality of aluminum alloy conductors, and a semiconductor shielding layer, an insulating layer, an insulation shielding layer and a metal shielding layer which are sequentially arranged at the outside of the aluminum alloy conductors; an inner sheath layer, an environmental protection paper tape, a corrugated aluminum sheath armor and an over sheath layer are sequentially arranged at the outside of the cable core; and an insulation filler is arranged between the cable core and the inner sheath layer. According to the high temperature and high voltage resistance aluminum alloy cable, an alloy cable substrates a copper cable, the weight of a cable is reduced, the installing cost is reduced correspondingly, abrasion between a device and the cable is reduced, and installation is easier.
Description
Technical field
The utility model relates to a kind of aluminium alloy high temperature high voltage resistant cable.
Background technology
High-tension cable is a kind of of power cable at present, refer to for transmitting 10KV-35KV(1KV=1000V) between power cable, be applied to the major trunk roads of electric power transfer more, generally need in actual use pipe laying threading, or built on stilts use, but general high voltage cable working temperature is-20 degrees Celsius to+90 degrees Celsius, for the existing weather conditions of China, in cold district, often there is the such situation of cracking, the present invention aims to provide the low temperature resistant high-tension cable of a kind of aluminium alloy, and high-tension cable also can be used safely in cold district.
High-tension cable high expensive, quality lays particular stress on, more complicated is installed in transportation, wrapped armouring there will be cable fault under certain external force extruding, so need poling to use when buried, or can only be positioned over crane span structure, but after placing crane span structure, external environment condition is larger on its impact, normal serviceability temperature mostly is-20 degrees Celsius to+90 degrees Celsius most.In China Three Eastern Provinces, Tibet, Xinjiang, area, Inner Mongol is used certain limitation.
Utility model content
The utility model object is that the defect existing for prior art provides a kind of aluminium alloy high temperature high voltage resistant cable.
The utility model for achieving the above object, adopt following technical scheme: a kind of aluminium alloy high temperature high voltage resistant cable, comprise cable core, described cable core comprises many aluminium alloy conductors and is successively set on the outer field shield semiconductors layer of described aluminium alloy conductor, insulating barrier, insulation screen and metal screen layer; The skin of described cable core is also disposed with inner restrictive coating, environmental protection paper tape, corrugated aluminum sheath armour and external sheath layer; Between described cable core and described inner restrictive coating, be provided with insulation filler.
Preferably, described aluminium alloy conductor is 8000 line aluminium alloy conductors.
Preferably, the base-material of described shield semiconductors layer, insulating barrier and insulation screen all adopts methyl ethylene phenyl siloxane rubber.
Preferably, described metal screen layer adopts copper strips to make.
Preferably, described insulation filler is glass cord.
Preferably, described inner restrictive coating and external sheath layer all adopt low-phenyl silicone rubber to make.
The beneficial effects of the utility model: alloy cable of the present utility model replaces copper cable, can reduce the weight of cable, corresponding reduction installation cost of while, and the wearing and tearing of minimizing equipment and cable, install more light.Shield semiconductors layer, insulating barrier, insulation screen and metal screen layer that aluminium alloy conductor skin sets gradually have good insulating effect, in high temperature and high pressure environment, can not prevent cable leakage, but also can shield external interference signals.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Embodiment
Shown in Fig. 1, for a kind of aluminium alloy high temperature high voltage resistant cable, comprise cable core, described cable core comprises many aluminium alloy conductors 1 and is successively set on the outer field shield semiconductors layer 2 of described aluminium alloy conductor 1, insulating barrier 3, insulation screen 4 and metal screen layer 5; The skin of whole described cable core is enclosed with inner restrictive coating 7, environmental protection paper tape 8, corrugated aluminum sheath armour 9 and external sheath layer 10 successively; Between described cable core and described inner restrictive coating, be provided with insulation filler 6.Described aluminium alloy conductor 1 is 8000 line aluminium alloy conductors.The base-material of described shield semiconductors layer 2, insulating barrier 3 and insulation screen 4 all adopts methyl ethylene phenyl siloxane rubber.Described metal screen layer 5 adopts copper strips to make.Described insulation filler 6 is glass cord.Described inner restrictive coating 7 and external sheath layer 10 all adopt low-phenyl silicone rubber to make.
The cable of this aluminium alloy high temperature high voltage resistant cable and same size compares, and the conductance of using this aluminium alloy conductor is 61% of international standard (IACS).Under same volume, the actual weight of aluminium is approximately 1/3rd of copper, according to this, calculates, and is meeting under the prerequisite of identical conduction performance, and the length of the aluminium alloy cable of identical weight is the twice of copper cable.Therefore, the weight of aluminium alloy cable is half of copper cable of same ampacity.When the cross-sectional area of conductor of aluminium alloy cable is long-pending while being 1.5 times of copper core, its electric property is substantially suitable.So use alloy cable to replace copper cable, can reduce the weight of cable, corresponding reduction installation cost of while, the wearing and tearing of minimizing equipment and cable, install more light.
Under extremely cold weather, above-mentioned aluminium alloy high temperature high voltage resistant cable, without buried channel poling, also can directly be used under low temperature environment, and has the protection of wrinkle aluminium alloy protecting jacket layer, and its lateral pressure resistant ability is stronger.The cable under environment that makes extremely to tremble with fear is installed easier also more economical.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
