Description

Flexible insulated cable with flame retardant property

Technical Field

The utility model relates to a technical field of cable specifically is a flexible insulated cable with fire retardant property.

Background

Wire and cable are used for transmitting electric energy or magnetic energy, information and wire products for realizing electromagnetic energy conversion, wire and cable in a broad sense are also called as cable for short, cable in a narrow sense is insulated cable, and it can be defined as: an aggregate consisting of; one or more insulation core, and their cladding that probably have respectively, total protective layer and outer jacket etc. wherein insulation flame retarded cable design and manufacturing are the most complicated, but present insulation flame retarded cable makes the cable flexibility poor because its inside adds various fire-retardant and insulating material, and the flexibility is poor makes cable installation use degree of difficulty increase, and the installation also damages the cable easily simultaneously.

SUMMERY OF THE UTILITY MODEL

For solving above-mentioned current insulating flame retarded cable because its inside various fire-retardant and insulating material of adding make the cable flexibility relatively poor, the flexibility is poor to make cable installation use the degree of difficulty increase, and the problem of the cable is also damaged easily in the installation simultaneously, realizes above insulating fire-retardant, flexible good, practical reliable purpose, the utility model discloses a following technical scheme realizes: the utility model provides a flexible insulated cable with fire retardant property, includes the conductor, the outside fixedly connected with isolation layer of conductor one, the outside fixedly connected with insulating layer of isolation layer one, the outside fixedly connected with isolation layer two of insulating layer, the outside swing joint of isolation layer two has fire-retardant layer, the outside fixedly connected with isolation layer three on fire-retardant layer, the outside fixedly connected with protective sheath of isolation layer three.

Furthermore, the first isolation layer is made of an aluminum foil material, and the insulation layer is formed by filling slender filamentary asbestos.

Further, the second isolation layer is made of aluminum foil, and the flame-retardant layer is made of strip-shaped mica tapes.

Furthermore, the third isolation layer is made of an aluminum foil material, and the protective sleeve is made of a flame-retardant polyethylene material.

The utility model provides a flexible insulated cable with fire behaviour. The method has the following beneficial effects:

1. this flexible insulated cable with fire behaviour can make the conductor and fire-retardant layer and protective sheath insulating through the inside asbestos silk of insulating layer, and the mica tape strip in fire-retardant layer makes the cable have good fire-resistant fire resistance simultaneously.

2. According to the flexible insulated cable with the flame retardant property, the insulating layer is formed by the filiform asbestos and the flame retardant layer is formed by the strip-shaped mica tapes, so that the cable can keep excellent flexibility under the characteristic of insulating flame retardance, and the practicability and reliability of cable installation and use are improved.

FIG. 1 is a schematic view of the internal partial sectional structure of the present invention;

fig. 2 is a schematic structural diagram of a portion a in fig. 1 according to the present invention.

In the figure: 1. a conductor; 2. a first isolating layer; 3. an insulating layer; 4. a second isolation layer; 5. a flame retardant layer; 6. a third isolating layer; 7. and (6) a protective sleeve.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples of the flexible insulated cable having flame retardant properties are as follows:

referring to fig. 1-2, a flexible insulated cable with flame retardant property includes a conductor 1, an insulation layer one 2 fixedly connected to an exterior of the conductor 1, an insulation layer 3 fixedly connected to an exterior of the insulation layer one 2, the insulation layer one 2 made of aluminum foil, and the insulation layer 3 filled with long and thin asbestos.

The second isolation layer 4 is fixedly connected to the outer portion of the second isolation layer 3, the flame-retardant layer 5 is movably connected to the outer portion of the second isolation layer 4, the second isolation layer 4 is made of aluminum foil, and the flame-retardant layer 5 is made of strip-shaped mica tapes.

Three 6 of fire-retardant layer 5's outside fixedly connected with isolation layer, three 6 of isolation layer's outside fixedly connected with protective sheath 7, three 6 adoption aluminium foil materials of isolation layer, protective sheath 7 adopts fire-retardant polyethylene material preparation to form, can make conductor 1 and fire-retardant layer 5 and protective sheath 7 insulating through the inside asbestos gauge of insulating layer 3, the mica tape strip of 5 inside fire-retardant layers makes the cable have good fire-resistant fire retardance simultaneously, constitute fire-retardant layer 5 that insulating layer 3 and strip mica tape are constituteed through filiform asbestos and can make the cable have and keep good flexibility under the fire-retardant characteristic of insulation, practicality and the reliability of cable installation use have been improved.

The working principle is as follows:

when flexible insulating flame retarded cable installation used, the user can conveniently make protective sheath 7 crooked, and protective sheath 7 crooked makes three 6 crooked isolation layers, and three 6 crooked isolation layers 5 crooked that make of isolation layer, and 5 crooked isolation layers make two 4 crooked isolation layers, and two 4 isolation layers make 3 crooked insulating layers, and 3 crooked isolation layers 2 crooked that make of insulating layer, and 2 crooked isolation layers make 1 crooked conductor.

When flexible insulation flame retarded cable met naked light, external high temperature made protective sheath 7 melting burning, and high temperature sees through aluminium foil isolation layer three 6 heating filiform asbestos fire-retardant layer 5, and the fire-retardant layer 5 of filiform asbestos prolongs high temperature and passes aluminium foil isolation layer two 4 times, and high temperature passes isolation layer two 4 heating strip mica tape insulating layer 3, and high temperature passes aluminium foil isolation layer one 2 heating conductor 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
