Description

A kind of Multi-functional aluminum sheath power cable

Technical field

The utility model relates to a kind of cables, and in particular to a kind of aluminium sheath power cable.

Background technique

With the rapid development of the national economy, special cable demand sharp increase, power cable is passed from simple electric power Transfer to multi-functional, multipurpose development.According to different function and purposes, power cable attached many new characteristics, as waterproof, Resist it is dry scratch, water resistant tree, shock resistance etc..In the past, the block-water performance of cable was limited primarily to submarine cable, on extra-high-tension cable, With to insulation water suction and water tree research and recognize intensification, it has been recognized that the importance of power cable waterproof.China south Side area level of ground water is higher or throughout the year rainy, and most of medium-low voltage power cables use underground laying, and cable may part Short-term or long-term leaching ditch is in water.Therefore, because the requirement of medium-low voltage power cable use occasion, has multi-functional aluminium sheath Power cable is particularly important.

Summary of the invention

Goal of the invention: the purpose of this utility model is to overcome deficiencies in the prior art, and providing one kind not only has The performances such as excellent electric property, mechanical performance, waterproof performance, water tree resistant property, resistance to mechanical impact, and product has structure Simply, the features such as light-weight, while there is preferable shielding properties again, it is alternatively arranged as the channel of short circuit current, protection can be played The Multi-functional aluminum sheath power cable of the effect of core.

Technical solution: in order to solve the above-mentioned technical problem, a kind of Multi-functional aluminum sheath electrical electricity described in the utility model Cable, it includes power core conductor, conductor shield is equipped with outside the power core conductor, outside the conductor shield Portion is equipped with insulating layer, and insulation screen is equipped with outside the insulating layer, and metallic shield is equipped with outside the insulation screen Layer, they form cable core, and several tangent settings of cable core are equipped with filled layer outside the cable core, set outside the filled layer Block water separation layer, and wrinkle alibate is equipped with outside the separation layer that blocks water, extrudes and is equipped with outside the wrinkle alibate Oversheath.

The cable core is arranged three, their circumscribed settings mutually.

Separation layer and the wrinkle alibate composition stop water of blocking water.

The separation layer that blocks water is semiconductive water blocking layer.

The oversheath is nonmetallic oversheath.

The utility model is suitable for fixed be laid in and exchanges 50Hz, voltage rating 26/35kV and power transmission and distribution below Make conveying electric energy on route.

Block water separation layer and the wrinkle alibate composition stop water, can prevent the invasion of water, reach and block water and prevent Damp purpose.

The wrinkle alibate can be used as metal sheath, have certain resistance to mechanical impact capacity, play protection to core Effect.

The wrinkle alibate can be used as metal screen layer, shield to core.

The utility model has the advantages that the utility model is compared with prior art, remarkable advantage is: first is that impermeable role can be played, The invasion for preventing water prevents XLPE insulated contact from generating water tree to moisture, extends cable service life；Second is that by being produced around electric current Raw magnetic field shielding prevents from externally generating interference in cable, improves sensitivity of the head end protective device in single-phase short circuit；Third is that It is capable of increasing shielding section, increases shield effectiveness, improves cable overload capacity；Fourth is that certain resistance to mechanical impact energy can be played Power, if in the case that cable is by external impacts, playing the role of safeguard protection to core.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples.

As shown in Figure 1, a kind of Multi-functional aluminum sheath power cable described in the utility model, it includes power core conductor 1, it is equipped with conductor shield 2 outside the power core conductor 1, insulating layer 3, In is equipped with outside the conductor shield 2 It is equipped with insulation screen 4 outside the insulating layer 3, metal screen layer 5 is equipped with outside the insulation screen 4, they are formed Cable core, the circumscribed setting mutually of three cable cores are equipped with filled layer 6 outside the cable core, are equipped with and block water outside the filled layer 6 Separation layer 7 is semiconductive water blocking layer, wrinkle alibate 8, the separation layer 7 that blocks water is equipped with outside the separation layer 7 that blocks water Stop water is formed with wrinkle alibate 8, impermeable role can be played, prevent the invasion of water, prevent XLPE insulated contact to water Divide and generate water tree, extend cable service life, extruded outside the wrinkle alibate 8 equipped with oversheath 9, is nonmetallic outer Sheath.Wherein wrinkle alibate 8 can be used as metal screen layer, magnetic field shielding will be generated around electric current in cable, and prevented pair Outer generation interference, improves sensitivity of the head end protective device in single-phase short circuit, while being capable of increasing shielding section, increases shielding Effect improves cable overload capacity；In addition wrinkle alibate 8 can be used as metal sheath, can play certain resistance to mechanical punching Ability is hit, if in the case that cable is by external impacts, playing the role of safeguard protection to core.

The utility model provides a kind of thinking and method, and there are many method and the approach for implementing the technical solution, with It is only preferred embodiments of the present invention described in upper, it is noted that for those skilled in the art, Without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications should also regard For the protection scope of the utility model, all undefined components in this embodiment can be implemented in the prior art.
