Abstract
The utility model relates to a luminous flame retardant cable for mine. The utility model belongs to the technical field of cables, particularly the technical field of luminous fireproof control cables. The utility model comprises conductors, an insulation layer, a winding and covering layer, a shielding layer and an outer sheath, wherein the insulation layer is arranged outside the conductors; the winding and covering layer is covered on cable cores of a cable which is composed of insulation wire core stranded wires. The utility model is characterized in that the fireproof mica tape winding and covering layer is arranged between the conductors and the insulation layer, and a luminous layer is extruded and covered at the surface of the outer sheath. Because an outer protection layer of the cable adopts the luminous layer which is mainly made of rare earth aluminate light storing luminous powder, when visual light, ultraviolet light, etc. irradiate, the luminous layer can store the light energy. In a dark state, the luminous layer slowly releases the stored light energy and generates fluorescence, thereby, the utility model achieves the goal of luminescence in dark environment.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to a kind of fireproof control cable technical field that can be luminous.
Background technology
Mine is as the very low workplace of visibility, in case emergency takes place, the big and small invisible electric wire in the well that is laid in just probably becomes the obstacle of operating personnel's safe escape, causes huge injury and loss to the people's lives and property.At present, that generally uses under the mine is common cable, when in the mine in case when the out-of-work emergency of lighting installation occurring owing to darkly brought obstacle, also bring very big inconvenience simultaneously for handling the accident that causes because of cable to the personnel escape.
The utility model content
The purpose of this utility model provides a kind of environment of the special operation place according to mine, has higher fireproof performance, good electric property and mechanical and physical performance, can be under pitch-dark environment luminous luminous flame-proof mining cable.
The purpose of this utility model is to realize like this, it comprises conductor, is located at the outer insulating barrier of conductor, is surrounded by polyester film lapping layer, screen and oversheath on the cable core of insulated wire cores twisted wire composition cable, it is characterized in that, be provided with the fire-resistant isinglass belt lapping layer between conductor and the insulating barrier, sleeve surface is extruded with luminescent layer.
Described screen adopts the total shielding of zinc-plated round copper wire braiding.
Lapping layer adopts the polyester film material, is provided with flame-retardant filler between the insulated wire cores twisted wire in the polyester film lapping layer.
The material that described oversheath surface extrudes is to be raw-material luminescent layer with the light-accumulative luminous powder of rare earth aluminate.
The luminescent layer that the utility model adopts owing to the outer jacket at cable, its main raw material(s) is the light-accumulative luminous powder of rare earth aluminate.Its operation principle is: when light source irradiation such as visible light, ultraviolet ray, this material can be saved its luminous energy, after light source is withdrawn under dark state, again the luminous energy of being saved is slowly released generation fluorescence, thereby reach purpose luminous under pitch-dark environment, the utility model is novel, and result of use is good.
