Problems solved by technology
[0004] At present, the overhead insulated conductors sold and used in the market are single-core or multi-core parallel structures. Since the overhead insulated conductors are mostly used outdoors, they have been exposed to wind, rain and sun for a long time, and cracks are prone to occur after years of insulation aging. In addition, when used indoors, when a fire occurs or it is close to a heat source, it will also cause insulation to melt or crack, thereby causing a trip and causing heavy property losses.
In addition, the existing single-core or multi-core overhead conductors are composed of conductors and polyethylene insulation, and have a single structure

Embodiment Construction
[0010] Such as figure 1 , the environment-friendly fire-resistant parallel overhead insulated wire of the present invention includes several insulated wires connected together, and is characterized in that the insulated wire includes a conductor 1 in the middle, a mica tape 2 is wound outside the conductor, and extruded outside the mica tape 2 Pack environmental insulation layer 3. ,
[0011] There are many specific application approaches of the present invention, and the above description is only a preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, some improvements can also be made without departing from the principles of the present invention. These improvements should also be regarded as the protection scope of the present invention.

The invention discloses an environment-friendly fire-resistant parallel overhead insulated wire, which comprises a plurality of insulated wires connected together, the insulated wire includes a conductor in the middle, a mica tape is wound outside the conductor, and an environment-friendly insulating layer is extruded outside the mica tape . The present invention is used outdoors for a long time, and even if cracks are generated due to aging of the insulation, since the mica material is protected between the conductor and the insulation, it will not cause phase-to-phase discharge and cause large-area electric tripping accidents. When used indoors, even if a fire occurs, it will not cause phase-to-phase discharge, and keep fire-fighting equipment and important equipment continuously energized.
Description
[0001] [0002] technical field [0003] The invention relates to the field of wires and cables, in particular to an outdoor and indoor environment-friendly fire-resistant parallel overhead insulated wire, which belongs to the technical field of cables. Background technique [0004] At present, the overhead insulated conductors sold and used in the market are single-core or multi-core parallel structures. Since the overhead insulated conductors are mostly used outdoors, they have been exposed to wind, rain and sun for a long time, and cracks are prone to occur after years of insulation aging. In addition, when used indoors, when a fire occurs or is close to a heat source, it will also cause insulation to melt or crack, thereby causing a trip and causing heavy property losses. In addition, the existing single-core or multi-core overhead wires are composed of conductors and polyethylene insulation, and have a single structure.
