Abstract
The utility model relates to a crosslinked polyethylene cable, including a core, a packing layer, a mica tape layer, a crosslinked polyethylene insulating layer, a waterproof layer and a restrictive layer, wherein the core includes a copper core and an insulating varnish layer cladding the copper core, the packing layer clads the cable core, the packing layer, mica tape layer, crosslinked polyethylene insulating layer, waterproof layer and restrictive layer are sequentially disposed from the inside out. The crosslinked polyethylene cable has advantages of simple structure, high temperature resistance, well water resistance, high strength and the like.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of twisted polyethylene cable, belongs to cable technology field.
Background technology
Twisted polyethylene cable consists of conductive cores, insulating barrier and packed layer etc. conventionally, and it has good electric property and is widely used.Yet the working temperature of the twisted polyethylene cable of prior art is lower, be generally below 70 ℃; Under hot environment, easily cause its insulating properties to reduce, safety is used in impact; Meanwhile, the water proofing property of twisted polyethylene cable is also poor.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved twisted polyethylene cable that has, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of twisted polyethylene cable of simple in structure, high temperature resistant and good waterproof performance.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of twisted polyethylene cable, and it comprises cable core, packed layer, mica belt, crosslinked polyetylene insulated layer, watertight composition and restrictive coating; Wherein, described cable core comprises the insulation enamelled coating on a bronze medal core and coated copper core; Described packed layer wraps up described cable core; Described packed layer, mica belt, crosslinked polyetylene insulated layer, watertight composition and restrictive coating from-inner-to-outer setting successively.
Twisted polyethylene cable of the present utility model is further set to: described cable core is specially two.
Twisted polyethylene cable of the present utility model is also set to: in described packed layer, further embed and have two steel wires.
Compared with prior art, the utlity model has following beneficial effect: twisted polyethylene cable of the present utility model has the plurality of advantages such as simple in structure, high temperature resistant, good waterproof performance and intensity height.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of twisted polyethylene cable of the present utility model.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of twisted polyethylene cable, and it is comprised of several parts such as cable core 1, packed layer 2, mica belt 3, crosslinked polyetylene insulated layer 4, watertight composition 5 and restrictive coatings 6.
Wherein, described cable core 1 comprises the insulation enamelled coating 12 on a bronze medal core 11 and coated copper core 11, and in the present embodiment, described cable core 1 is specially two.
The described cable core 1 of described packed layer 2 parcel further embeds and has two steel wires 7, thereby makes the stretch-resistance of this twisted polyethylene cable better in this packed layer.。
Described packed layer 2, mica belt 3, crosslinked polyetylene insulated layer 4, watertight composition 5 and restrictive coating 6 from-inner-to-outer setting successively.Described mica belt 3 can improve the thermal endurance of this cable greatly; Described watertight composition 5 can make the water proofing property of this cable better; And described restrictive coating 6 can be protected and avoid quick aging this cable.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection range of this creation within all spirit in this creation and principle.
