Abstract

The utility model relates to an insulating conducting wire, which is composed of an inner and an outer conducting wires, wherein, the inner conducting wire is composed of a solid core-shaped inner conductor (1) coated with an inner insulating layer (2), and the outer conducting wire is composed of a tubular outer conductor (3) wrapped on the surface of the inner conducting wire and coated with an outer insulating layer (5). The conducting wire can be used for power supply and prevent electric larceny in a parallel branch method.

Description

A kind of insulated conductor

The utility model relates to the low-voltage power supply lead, particularly a kind of insulated conductor with anti-stealing electricity function.

Existing low-voltage power supply insulated conductor, live wire and zero line mostly adopt by single insulated conductor and constitute side by side.For setting up conveniently, when at present a kind of the manufacturing being arranged also the insulating barrier of double joint lead is pressed into the composite type insulated conductor of one.But no matter be that is a kind of, the conductor of two leads all is to be parallel distribution in the space, and this just provides convenience for the illegal stealing of some lawless persons at present.Because electricity filching person mostly adopts the insulating barrier of the current supply line of kilowatt-hour meter front is destroyed, the conductor of live wire and zero line is come out after, will illegally use electric line in parallel on it.

Thereby the purpose of this utility model is to provide a kind of insulated conductor that on current supply line electricity consumption branch road in parallel has anti-stealing electricity function that is difficult for.

The insulated conductor that the utility model provides is made up of inside and outside double joint lead, and wherein inside conductor is made of the real core shape inner wire that covers inner insulating layer outward, and outer conductor is made of the tubular outer conductor that is wrapped in the inside conductor surface, covers external insulation layer outward.

With the insulated conductor power supply of said structure, expose the inner wire of inside conductor, just must destroy the tubular outer conductor of outer conductor, this will cause with electric line destroyed, or causes short-circuit between conductors.Therefore, with this insulated conductor power supply, the lawless person rethinks stealing, and the way with parallel branch realizes on lead with regard to being difficult for, thereby makes this lead have anti-stealing electricity function.

Below in conjunction with accompanying drawing execution mode of the present utility model is further described.

Accompanying drawing 1 is the sectional view of the utility model insulated conductor;

Accompanying drawing 2 is the schematic diagram after successively exhuming in the utility model insulated conductor end.

See figures.1.and.2, the real core shape inner wire 1 of the inside conductor of the utility model insulated conductor is by seven stranded forming of plain conductor; The inner insulating layer 2 that coats is made of the flame-proof PVC plastics; Tubular outer conductor 3 centers on inner insulating layer 2 stranded forming by the thin plain conductor of multiply, and the sectional area of outer conductor is equated with the inner wire sectional area; The wrapped glass tape of outer conductor outer surface constitutes flame-retardant layer 4, and the outside coats the external insulation layer 5 that is made of weather resistant PVC plastics again.

This insulated conductor not only has anti-stealing electricity function, and has the intensity height concurrently, and wind resistance snow load-bearing capacity is strong, anti-flammability Good, low temperature resistant, the advantages such as convenient are set up in anti-aging.

Above-mentioned insulated conductor both can have been done single phase power supply (such as distribution in the room, house lead in etc.) and use, and also can do three-phase four The line power supply is used. When doing three-phase and four-line power supply use, utilize two leads to get final product side by side.
