Abstract
A cross-linked polyethylene insulated steel wire armored medium-low voltage power cable is characterized by mainly comprising a conductor (1), a conductor shield layer (2), a cross-linked polyethylene insulating layer (3), an insulating shield layer (4), a filling layer (6), a nonwoven fabrics layer (7), an inner sheath (8), a steel wire armor layer (9) and an outer sheath (10). The power cable finely meets power transmission requirements of 36/6kV to 26/35kW, has a multiple shield structure and an insulating structure, and not only has fine insulating shielding performance, but also can bear higher current, and the highest long-term working temperature of the conductor can reach 90 DEG C.
Description
Technical field
The utility model relates to the power cable technical field, especially a kind of crosslinked polyetylene insulated wire armoring mesolow power cable.
Background technology
Power cable is the cable that is used to transmit and distribute electric energy.Be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.
Shielding has significance for power cable; screen is set in cable usually; be mainly used in ground connection; when short circuit, electric current is imported the earth; some cable shield can be used as the effect that armouring plays protection cable itself simultaneously; the crosslinked cable that 6KV is above, its internal shield can also prevent the damage of conductor burr to insulation.
Summary of the invention
The purpose of this utility model is to provide a kind of crosslinked polyetylene insulated wire armoring mesolow power cable, and this power cable has shielding construction, can effectively satisfy the specific demand of shielding occasion.
The technical solution of the utility model is:
A kind of crosslinked polyetylene insulated wire armoring mesolow power cable, it mainly is made up of conductor, conductor shield, crosslinked polyetylene insulated layer, insulation screen, packed layer, nonwoven layer, inner sheath, wire armoring layer and oversheath, described conductor is provided with conductor shield outward, conductor shield is provided with crosslinked polyetylene insulated layer outward, the outer insulation screen that is provided with of crosslinked polyetylene insulated layer, insulation screen is provided with inner sheath outward, be provided with packed layer between insulation screen and the inner sheath, inner sheath is provided with the wire armoring layer outward, and wire armoring layer outside is oversheath.

The material of described conductor is copper or aluminium.
The material of described oversheath is polyethylene or polyvinyl chloride.
Described insulation screen arranged outside copper strips screen.
Be provided with nonwoven layer between described packed layer and the inner sheath.
The beneficial effects of the utility model are:
Crosslinked polyetylene insulated wire armoring mesolow power cable of the present utility model can finely satisfy the electric power transfer demand of 3.6/6kV～26/35kW, have multiple shield structure and insulation system, not only has the good insulation performance shielding properties, more can bear bigger electric current, the long-term maximum operating temperature of conductor can reach 90 ℃.
Crosslinked polyetylene insulated wire armoring mesolow power cable of the present utility model generally be embedded in the soil or be laid in indoor, raceway groove, in the tunnel, insulation distance is little between line, without shaft tower, take up an area of few, space on the not occupation of land face substantially; Be subjected to weather conditions and surrounding environment influence little, transmission performance is stable, the reliability height; Advantage such as have also that distributed capacitance is big, maintenance workload is few and the electric shock possibility is little, can be laid in requires to have the stationary applica-tions of strong shielding.
