CN202110871U - Environmental-friendly fire-retarding parallel overhead insulated wire - Google Patents

Abstract

The utility model discloses an environmental-friendly fire-retarding parallel overhead insulated wire which comprises a plurality of insulated wires which are mutually connected together; each insulated wire comprises a middle conductor; a mica tape is wound outside the conductor; and an environmental-friendly insulating layer is extruded outside the mica tape. The environmental-friendly fire-retarding parallel overhead insulated wire is used outdoors for a long time; although a crack is generated due to aging insulation, as the conductor and the insulating are protected by a mica material, inter-phase discharge can not be generated and the large-area blackout accidents caused by the inter-phase discharge are further avoided. When the wire is used indoors, although a fire occurs, inter-phase discharge also can not be generated so as to maintain the power-on state of the fire fighting apparatuses and important equipments.

Description

The empty insulated conductor of the fire-resistant parallel shelf of a kind of environment-friendly type

Technical field

The utility model relates to the electric wire field, specifically is the fire-resistant parallel suspended insulated guide wire of a kind of open air and indoor environmentally-friendly type, belongs to the cable technology field.

Background technology

At present, the suspended insulated guide wire of sale and use is single core or multicore parallel construction on market, because mostly suspended insulated guide wire is outdoor use; Long-time experience is exposed to wind and rain and the sun tans by the sun, and is prone to produce the crack after year ageing of insulation of a specified duration, causes that alternate discharge causes large tracts of land to jump electrification; During indoor in addition use,, also can impel insulation that fusing or cracking take place when breaking out of fire or when thermal source is nearer; Thereby cause and jump electricity, cause the property heavy losses.In addition, existing single core or multicore aerial condutor are made up of conductor and polyethylene insulation, and structure is single.

The utility model content

The utility model technical problem to be solved provides and a kind ofly after long-term the use, also can not cause alternate discharge even the crack appears in insulation, causes large tracts of land to jump the empty insulated conductor of the fire-resistant parallel shelf of environment-friendly type of electrification.

The empty insulated conductor of the fire-resistant parallel shelf of the described a kind of environment-friendly type of the utility model comprises the some insulated leads that interconnect, and the conductor in the middle of said insulated conductor comprises twines mica tape outside conductor, outside mica tape, extrude the environmental protection insulating barrier.

Even the utility model is out of doors through exposing to wind and rain; The sun tans by the sun; Year for a long time after the ageing of insulation, insulation produces the crack, owing in the middle of conductor and the insulation mica material protection is arranged, can therefore not cause alternate discharge; Cause large tracts of land jumping electrification, so can protect the property loss that causes because of power breakdown.

This cable is when indoor use, even breaking out of fire also can keep normal power-up after the insulation fusing; Can not cause alternate discharge; Keeping fire-fighting equipment and visual plant to continue energising, is to reduce the expensive time of guarantor that property loss is won, in addition in the environment-friendly type insulated material that uses of our company not Halogen do not have element; Can not produce denseer black smoke after catching fire, can not make the personnel of escape in catching fire suck this smog and produce the stupor of suffocating.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Like Fig. 1; The empty insulated conductor of the fire-resistant parallel shelf of the environment-friendly type of the utility model comprises the some insulated leads that interconnect, and it is characterized in that said insulated conductor comprises middle conductor 1; Outside conductor, twine mica tape 2, outside mica tape 2, extrude environmental protection insulating barrier 3.

The concrete application approach of the utility model is a lot; The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.

Claims (1)

1. the empty insulated conductor of the fire-resistant parallel shelf of an environment-friendly type; Comprise the some insulated leads that interconnect; It is characterized in that said insulated conductor comprises middle conductor (1), outside conductor, twine mica tape (2), outside mica tape (2), extrude environmental protection insulating barrier (3).
