But traditional fireproof control cable is due to self built-in electrical insulation line weave in, structural design is unreasonable, causes refractory temperature lower, once breaking out of fire, in high temperature and flame, burn, can ensure that the time of energising is shorter, cannot guarantee the control requirement of case of emergency.
Summary of the invention
That technical problem to be solved by this invention is to provide is a kind of reasonable in design, convenient processing, durability is high, can improve the cable of self fire resistance, i.e. a kind of fireproof control cable.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of fireproof control cable, comprises sheath, sheath, external insulation layer, outer conductor, radially interlayer, main fireprotection layer, inner insulating layer and inner wire, and described sheath is arranged in sheath, described main fireprotection layer and sheath dead in line; Described inner insulating layer is fixed in main fireprotection layer; Described inner wire is arranged in inner insulating layer; Described radially interlayer is arranged in the annular space that main fireprotection layer and sheath form symmetrically, and radially one end of interlayer is all connected with the inner headed face of sheath, and radially the other end of interlayer is all connected with the periphery of main fireprotection layer; Described external insulation layer being distributed in the sector space that radially dividing plate and sheath, main fireprotection layer form symmetrically, and the periphery of external insulation layer is with radially dividing plate is tangent.Utilize radially interlayer that external insulation layer, outer conductor are separated in different sector spaces, like this time on fire, can External Insulation layer, outer conductor carries out separately protected, avoid the generation of reciprocal combustion phenomenon, in high temperature and flame environment, burning can increase the time that ensures energising, thereby has guaranteed the control requirement of case of emergency; Utilize main fireprotection layer protection inner insulating layer, inner wire, further external insulation layer, outer conductor and inner insulating layer, inner wire are separated, improved the fire resistant quality of cable.
Described radially interlayer comprises side fireprotection layer, median septum and No. two side fireprotection layers No. one, and described median septum is between a side fireprotection layer, No. two side fireprotection layers, and median septum and a side fireprotection layer, No. two side fireprotection layers are connected.A described side fireprotection layer, No. two side fireprotection layers and main fireprotection layer are made by fireproof mica material, and described median septum is made up of the elastomeric material of good toughness.Side fireprotection layer, No. two side fireprotection layers and main fireprotection layer can be protected external insulation layer, outer conductor and inner insulating layer and inner wire in the time of breaking out of fire; Median septum can improve the toughness of cable self, like this in the actual use procedure of cable, as occurs bending or pulls while drawing, has avoided cable to occur skin breakage or inner conductor fracture, has guaranteed the normal operation of equipment and control device.
The invention has the beneficial effects as follows: the present invention has reasonable in design, convenient processing and durability advantages of higher, adopt radially interlayer and main fireprotection layer, can External Insulation layer, outer conductor and inner insulating layer and inner wire carry out separately protected, avoid the generation of reciprocal combustion phenomenon, in high temperature and flame environment, burning can increase the time that ensures energising, thereby has guaranteed the control requirement of case of emergency; And improved the toughness of cable self, avoid, bending or pull cable generation skin breakage or inner conductor fracture while drawing, having extended the useful life of self.
