Abstract
The utility model provides a waterproof type aluminum alloy power cable, which comprises a cable body, the cable body constitute by a plurality of groups, the group include conductor, insulating layer and the first band that blocks water, the conductor surface be equipped with the insulating layer, the insulating layer surface be equipped with the first band that blocks water, a plurality of group surfaces be equipped with the second band that blocks water, the second block water and be equipped with the gasket for packing that blocks water between band and a plurality of group, the second block water the band surface and be equipped with the inner sheath, the inner sheath surface be equipped with composite aluminium -plastic tape, the composite aluminium -plastic tape surface be equipped with the oversheath, a plurality of groups strand the formation cable core each other, the beneficial effect of the utility model: inside preventing that moisture from diping the conductor, prevent that the conductor from the oxidation appearing and leading to cable current -carrying ability to descend, can effectively organize moisture to dip the insulating layer, prevent the accelerated ageing of insulating layer, improve cable life.
Description
Technical field
The utility model relates to technical field of electric wires and cables, particularly a kind of water proof type aluminium alloy power cable.
Background technology
Along with the continuous scarcity of copper ore resource, the continuous rising of copper material price, copper conductor power cable is on the high side and proportion is bigger than normal, aluminium alloy power cable adopts advanced conductor annealing process, with the price that it is cheap, excellent fire-retardant, anticorrosion, resist bending, creep resistant, the advantage such as lightweight, aluminum alloy conductor power cable is extensively approved by market.But aluminium alloy cable is laying and run duration, when system of laying is improper, in running mechanical stress external force can cause the coat layer of power cable and insulating barrier is damaged or joint damage time, moisture or moisture can immerse along cable radial direction or axial clearance, aluminium alloy conductor is caused to be oxidized seriously under working voltage, the accelerated ageing of insulating barrier meeting simultaneously, and cause within a short period of time joint loose contact, current capacity degradation or insulating barrier to puncture, cause cable fault to cause power failure.Conventional water-proof cable structure adopts polyethylene as outer jacket, can only play certain waterproof effect, can not tackle the problem at its root when cable is not mechanically damaged.
Utility model content
For existing technical deficiency, the utility model provides a kind of water proof type aluminium alloy power cable.
To achieve these goals, technical solution adopted in the utility model is: a kind of water proof type aluminium alloy power cable, comprise cable body, described cable body is made up of some line groups, described line group comprises conductor, insulating barrier and first blocks water band, described conductor outside surfaces is provided with insulating barrier, described insulating barrier outer surface is provided with first and blocks water band, described some line group outer surfaces are provided with second and block water band, described second blocks water between band and some line groups is provided with the gasket for packing that blocks water, the described second band outer surface that blocks water is provided with inner sheath, described inner sheath outer surface is provided with aluminium-plastic tape, described aluminium-plastic tape outer surface is provided with oversheath.
The mutual stranded formation cable core of described some line groups.
The beneficial effects of the utility model:
1, the utility model cable insulation adopts Halogen water proof type irradiation crosslinked polyolefin insulating, and can prevent moisture from immersing conductor, oxidation causes cable current capacity to decline to prevent conductor from occurring.
2, the outer wrapped band that blocks water of the utility model cable insulation, effectively tissue water can divide immersion insulating barrier, prevent the accelerated ageing of insulating barrier, raising cable useful life.
3, the utility model cable filling and band all adopt material water-proof material, can effectively stop moisture to immerse cable inner.Improve the useful life of each structure sheaf of cable.
4, the utility model cable inner sheath adopts medium density polyethylene sheath, and (minimum serviceability temperature can reach-60 DEG C to have excellent low temperature resistant and anti-cracking performance; Power cable restrictive coating easily produces cracking phenomena in installation process, effectively can prevent the cracking of restrictive coating), water absorption is little, and water resistance is excellent.
5, vertical bag one deck aluminium-plastic tape before the utility model cable jacket, the face of moulding can bond with water proof type halogen-free polyolefin oversheath, improves the water resistance of cable, even if certain damage appears in oversheath, still moisture can be stoped to immerse cable inner, better promote the water resistance of cable.
Accompanying drawing explanation
Fig. 1 is the beneficial effects of the utility model.
