Abstract
The invention discloses a fireproof cable which comprises a cable core, a wrapping belt layer, a high-temperature-resisting layer and a PVC elastic body protection sleeve. A fireproof layer is further arranged on the outer side of the high-temperature-resisting layer, the fireproof layer is composed of a plurality of fireproof belts with the round cross sections, the fireproof belts are in circumferential tangency with each other, the fireproof belts are made of chlorinated rubber containing glass fibers, and the high-temperature-resisting layer is made of glass fibers containing mica. The fireproof cable is widely applied to the fields of electricity generation, metallurgy, chemical engineering and petroleum, is especially suitable for being exposed in the sun for a long time and the high-temperature work environment and has excellent high-temperature resistance and stronger fireproof performance. Furthermore, the allowed highest work environment temperature of the fireproof cable is 105 DEG C, and the safety of the fireproof cable is greatly improved.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of fireproof cable.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, also constantly improves the quality requirement of cable.Such as cruelly leak the cable used under solar radiation and in high-temperature work environment for a long time, higher requirement is proposed to fireproofing of cable resistance to elevated temperatures.Once fireproofing of cable resistance to elevated temperatures just may cause very big hidden danger not.
Therefore, only meet the requirements, could the better fail safe ensureing these field inner cables.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of fireproof cable.
The present invention takes following technical scheme to realize: a kind of fireproof cable; it comprises core, belting layer, high-temperature-resistant layer and PVC elastomer protective sleeve; also fireprotection layer is provided with in the outside of described high-temperature-resistant layer; described fireprotection layer is that circular fire guard forms by several cross sections; between described fire guard is mutual, circumference is tangent; described core is arranged radially centered by filler, and the periphery of two adjacent cores contacts with each other.
Particularly, described fire guard material is the chlorinated rubber containing glass fibre, and described high-temperature-resistant layer material is micaceous glass fibre; Described filler is that material silicon rubber polyvinyl chloride composite silicone rubber forms.
The present invention has following beneficial effect in sum: the present invention is widely used in the fields such as generating, metallurgy, chemical petroleum, is particularly useful for cruelly leaking the cable used under solar radiation and in high-temperature work environment for a long time.This utility model has excellent resistance to elevated temperatures and stronger fire protecting performance, allows operational environment maximum temperature to be 105 DEG C, allows to use 2.5 hours in 200 DEG C of hot environments, substantially increases the fail safe of cable.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, filler; 2, core; 3, belting layer; 4, high-temperature-resistant layer; 5, fireprotection layer; 6, PVC elastomer protective sleeve.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1; a kind of fireproof cable, it comprises core 2, belting layer 3, high-temperature-resistant layer 4 and PVC elastomer protective sleeve 6, is also provided with fireprotection layer 5 in the outside of described high-temperature-resistant layer 4; described high-temperature-resistant layer 4 material is micaceous glass fibre, greatly strengthen the thermal and insulating performance of cable.
As preferred version of the present invention, core 2 of the present invention is arranged radially centered by filler 1, and the periphery of two adjacent cores 2 contacts with each other.
As preferred version of the present invention, fireprotection layer 5 of the present invention is that circular fire guard forms by several cross sections, and between described fire guard is mutual, circumference is tangent.
As preferred version of the present invention, fire guard material of the present invention is the chlorinated rubber containing glass fibre, can effectively prevent hot environment to the destruction of cable, improves fireproofing of cable performance significantly.
As preferred version of the present invention, described filler 1 of the present invention is silicon rubber.
This cable allows operational environment maximum temperature to be 105 DEG C; Allow to use 2.5 hours in 200 DEG C of hot environments, substantially increase the fail safe of cable.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
