Abstract
The utility model discloses a damage-resistant underwater power cable special for shallow seas and lakes. The power cable comprises a plurality of electric power units, a water resistant belt layer, an inner sheath layer and an outer sheath layer. The water resistant belt layer, the inner sheath layer and the outer sheath layer wrap the plurality of electric power units in order. The gaps formed among the plurality of electric power units inside the water resistant belt layer contain fillers. Each electric power unit has a conductor cable core. A conductor shielding layer, an insulation layer, an insulation shielding layer and a copper belt shielding layer wrap the conductor cable core in order. A chain steel tape armored layer is arranged outside the outer sheath layer. A water-resistant lead sleeve layer is arranged between the inner sheath layer and the outer sheath layer. The power cable with the above structure can prevent damage of the power cable caused by factors of anchor sinking, net application and the like effectively, prevents water with high pressure from permeating into the interior of the power cable, and has good radial water resistant effects.
Description
Technical field
The utility model relates to a kind of power cable, specifically relates to a kind of shallow sea, the special tamper-proof power cable under water in lake.
Background technology
Power cable is the cable for transmitting and distribute electric energy, the structure of common power cable mainly comprises multiple power units and is sequentially coated on belting layer and the inner/outer sheath layer outside multiple power units, there is filler at gap place between multiple power units, each power unit has conductor thread core, conductor thread core is sequentially coated with conductor shield, insulating barrier, insulation screen and copper strip shielding layer outward, some power cable, in order to meet underwater operation, is also provided with water blocking layer.China coastline is wriggled long, offshore island is more, inland lake is widely distributed, for shallow sea, lake region there is sinker, some may destroy the factor of power cable under water to execute net etc., are not also specifically designed to the tamper-proof power cable under water in shallow sea, lake at present.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly can effectively prevents while using under water because of sinker, executes the special tamper-proof power cable under water in shallow sea, lake that the factors such as net are damaged power cable.
For solving the problems of the technologies described above, the utility model shallow sea, the special tamper-proof power cable under water in lake, comprise multiple power units and be sequentially coated on the belting layer that blocks water, inner restrictive coating and the external sheath layer outside multiple power units, the gap place forming between the multiple power units that block water in belting layer has filler, each power unit has conductor thread core, conductor thread core is sequentially coated with conductor shield, insulating barrier, insulation screen and copper strip shielding layer outward, and described external sheath layer outside is also provided with chain steel-tape armouring layer.
As further improvement of the utility model, between described inner restrictive coating and external sheath layer, be provided with the plumbous jacket layer that blocks water.
The shallow sea of said structure, the special tamper-proof power cable under water in lake, adopt external sheath layer outside to be also provided with the structure of chain steel-tape armouring layer, because chain steel-tape armouring layer has very high mechanical strength, can effectively prevent because of sinker, execute the damage that the factors such as net cause power cable; Owing to being provided with the plumbous jacket layer that blocks water between described inner restrictive coating and external sheath layer, while use, can effectively prevent that the water of elevated pressures is penetrated into power cable inside under shallow sea and Lake Water, can guarantee well radial water-resisting effect of the present utility model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the cross-sectional view of the utility model shallow sea, the special tamper-proof power cable under water in lake.
Embodiment
Referring to Fig. 1, the utility model shallow sea, the special tamper-proof power cable under water in lake, comprise multiple power units 1 and be sequentially coated on the belting layer 2 that blocks water, inner restrictive coating 3 and the external sheath layer 5 outside multiple power units 1, the gap place forming between the multiple power units 1 that block water in belting layer 2 has filler 6, each power unit 1 has conductor thread core 10, conductor thread core 10 is outer is sequentially coated with conductor shield 11, insulating barrier 12, insulation screen 13 and copper strip shielding layer 14, and described external sheath layer 5 outsides are also provided with chain steel-tape armouring layer 7.
Between described inner restrictive coating 3 and external sheath layer 5, be provided with the plumbous jacket layer 4 that blocks water.
Described conductor thread core 10 is preferably water-blocking conductor core; Described external sheath layer 5 is preferably HDPE external sheath layer.
