Description
Technical Field
The utility model relates to a cable manufacture technical field, in particular to high light transmittance ratio cable.
Background
With the development of society and the wide application of electric power, the use amount of cables is also increasing. Traditional cable insulation material or cladding material adopt PVC etc. more, and the cable that adopts this kind of material burning can send dense cigarette in the conflagration, and the luminousness is not high, and personnel in time salvage, quick sparse and effective fire extinguishing when influencing the conflagration.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high light transmittance ratio cable to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a high-light-transmittance cable comprises three cable cores, a protective sleeve and filler strips, wherein the cable cores and the filler strips are arranged in the protective sleeve, the number of the cable cores is three, the cable cores sequentially comprise a conductor, a conductor shielding layer, a crosslinked polyethylene insulating layer and a steel wire reinforcing layer from inside to outside, the filler strips are Y-shaped, and the three cable cores are respectively positioned in three V-shaped grooves of the filler strips; the protective sleeve is sequentially provided with a ceramic silicon rubber wrapping tape layer, a steel tape armor layer and a halogen-free flame-retardant polyolefin protective sleeve from inside to outside; fire prevention mud is filled between the ceramic silicon rubber winding band layer and the cable core and between the ceramic silicon rubber winding band layer and the filling strips.
Preferably, the conductor shielding layer is an aluminum foil shielding layer.
Preferably, the filling strip is a ceramic silicon rubber filling strip, and a Y-shaped hollow hole is formed in the center of the filling strip.
The principle and the beneficial effect of the application are that: the conductor can be made of conductive materials such as copper wires, copper-clad aluminum wires or stranded copper wire strands and the like, and mainly plays a role in conducting electricity; the conductor shielding layer arranged outside the conductor adopts an aluminum foil shielding layer, and can also adopt mechanisms such as a copper net and the like according to the requirements of use occasions during specific application, and the conductor shielding layer mainly plays a role in shielding an electric field and avoids the interference of the electromagnetic field generated by current in the conductor on the outside; the crosslinked polyethylene insulating layer mainly plays a role in coating and insulating the conductor; the stranded steel wire reinforcing layer is arranged outside the crosslinked polyethylene insulating layer and mainly used for improving the tensile strength of the cable core; the filling strips are Y-shaped and divide the three cable cores, so that the insulating effect is achieved, and the filling strips are made of ceramic silicon rubber and can be ceramic when in fire, so that the conductors are protected, short circuit and electric leakage are avoided, and the fireproof effect is improved; in addition, the center of the filling strip is provided with a Y-shaped hollow hole, so that the weight and the cost are reduced, and the flexibility of the whole cable can be improved. The ceramic silicon rubber wrapping band layer is ceramic during combustion, so that the fire resistance is improved, the fireproof mud can be prevented from falling off, the steel wire reinforcing layer twisted on the outermost layer of the cable core can be mutually embedded with the extrusion-molded fireproof mud in a pressing manner, the bonding strength of the fireproof mud and the cable core is improved, the overall strength of the cable can be improved by the steel band armor layer, and the rat-proof effect is achieved; the halogen-free flame-retardant polyolefin sheath has the advantages of less smoke amount, high light transmittance and no harmful gas generation in case of fire.
Has the advantages that: reasonable structure, strong fire-proof capability, high integral strength and high light transmittance in case of fire.
