Description

Fire-proof high-temperature resistant cable

Technical field

The utility model is related to technical field of electric wires and cables, more particularly to a kind of electric insulating quality and the good fire prevention of anti-flammability High temperature-resistant cable.

Background technology

With the continuous improvement of people's living standard, to the finishing in such as workplace, market, the residence of the environment residing for people It is required that also correspondingly improving, electrical equipment is also more and more, is no lack of some powerful electrical equipments.And often use wooden etc. Combustible material is used as finishing material.Electrical equipment is more then to be caused to increase by the electric current of electric wire, and the electric current of electric wire is when increasing, The caloric value increase of electric wire is then easily caused, fire is easily caused if it can not radiate well.In this case, generally then The conductor of overstriking electric wire is needed, the wrapper layer also needed in addition outside to conductor is transformed.Additionally, the environment residing for contingency electric wire Generation fire event, if the anti-flammability of electric wire is good, can effectively prevent event of fire from causing to damage to electric wire, it is to avoid to cause Bigger loss.

Therefore, a kind of electric insulating quality and the good fire-proof high-temperature resistant cable of anti-flammability are needed badly.

Utility model content

The purpose of this utility model is to provide a kind of electric insulating quality and the good fire-proof high-temperature resistant cable of anti-flammability.

To achieve these goals, the technical scheme of the utility model offer is：The utility model discloses one kind fire prevention High temperature-resistant cable, includes conductor, the first insulating barrier, asbestos fibre layer, the second insulating barrier and fireproof casing, institute successively from inside to outside The first insulating barrier described in conductor outer cladding is stated, the asbestos fibre layer is formed by the asbestos fibre braiding that vertical and horizontal are laid, Second insulating barrier is polyethylene cannula, and the fireproof casing includes bulkiness glass layer and in the bulkiness glass Fibrage outer covering iron oxide red layer of silica gel.

First insulating barrier includes polypropylene layer and the Teflon layer being coated on outside the polypropylene layer.

The conductor is mutually curled up by some copper cores and formed.

The copper core is nickel plating copper core.

The copper core is tin plating copper core.

The thickness of first insulating barrier is 0.3~0.5 millimeter, and the thickness of second insulating barrier is 0.7~1 millimeter.

The iron oxide red layer of silica gel outer wall is coated with reflective enamelled coating along the conductor length direction.

Compared with prior art, because in the utility model fire-proof high-temperature resistant cable, first insulating barrier includes poly- Propylene layer and the Teflon layer being coated on outside the polypropylene layer, the stone that the asbestos fibre layer is laid by some vertical and horizontal Cotton fiber braiding is formed, and second insulating barrier is polyethylene cannula.The Teflon layer has excellent antiacid alkali and resists each The characteristics of planting organic solvent, and asbestos fibre layer then can also bear various shocks with excellent fireproof high-temperature resistant performance, in addition The bulkiness glass layer has good fire protecting performance, and the iron oxide red layer of silica gel then has good water tightness Energy and resistance to elevated temperatures.

By following description and with reference to accompanying drawing, the utility model will become more fully apparent, and these accompanying drawings are used to explain this The embodiment of utility model.

Brief description of the drawings

Fig. 1 is the schematic diagram of the one embodiment in the section of the utility model fire-proof high-temperature resistant cable.

Fig. 2 is the external structure schematic diagram of fire-proof high-temperature resistant cable as shown in Figure 1.

Specific embodiment

With reference now to Description of Drawings embodiment of the present utility model, the element numbers being similar in accompanying drawing represent similar unit Part.As described above, as shown in figure 1, fire-proof high-temperature resistant cable 100 disclosed in the utility model embodiment, wraps successively from inside to outside Conductor 1, the first insulating barrier 2, asbestos fibre layer the 3, second insulating barrier 4 and fireproof casing 6 are included, the described in the outer cladding of the conductor 1 One insulating barrier 2, first insulating barrier 2 includes polypropylene layer 21 and the Teflon layer 22 being coated on outside the polypropylene layer 21, The asbestos fibre layer 3 is formed by the asbestos fibre braiding that vertical and horizontal are laid, and second insulating barrier 4 is polyethylene jacket Pipe, the fireproof casing 6 includes bulkiness glass layer 61 and in the outer covering iron oxide of the bulkiness glass layer 61 Red layer of silica gel 62.It should be noted that the Teflon layer 22 be by Teflon lotion applicator outside the polypropylene layer 21 And drying is formed.

During one is implemented, as shown in figure 1, the conductor 1 is mutually curled up by seven copper cores forming.

In one embodiment, the copper core is nickel plating copper core.

In one embodiment, the copper core is tin plating copper core.

In one embodiment, as shown in figure 1, the thickness of first insulating barrier 2 is 0.3~0.5 millimeter, described second is exhausted The thickness of edge layer 4 is 0.7~1 millimeter.

In one embodiment, as shown in Fig. 2 the outer wall of iron oxide red layer of silica gel 62 is coated along the conductor length direction There is reflective enamelled coating 5.By the reflective enamelled coating 5, can be easily found in the state of light is bad, play warning function.

Compared with prior art, with reference to Fig. 1 and 2, due in the utility model fire-proof high-temperature resistant cable 100, described One insulating barrier 2 includes polypropylene layer 21 and the Teflon layer 22 being coated on outside the polypropylene layer 21, the asbestos fibre layer 3 by The asbestos fibre braiding that vertical and horizontal are laid is formed, and the Teflon layer 22 has excellent antiacid alkali and resists various organic molten The characteristics of agent, and asbestos fibre layer 3 then can also bear various shocks with excellent fireproof high-temperature resistant performance, it is described bulk in addition Property glass layer 61 have good fire protecting performance, the iron oxide red layer of silica gel 62 then have good water sealing property and Resistance to elevated temperatures.

Above disclosed is only preferred embodiment of the present utility model, can not limit this practicality with this certainly new The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered Scope.
