Technical field
The utility model relates to a kind of cable, is specially a kind of high temperature resistant computer and uses shielded type cable.
Background technology
The computer cable that uses at present; Usually form by conductor, insulating barrier, lapping layer, screen, oversheath, but aspect resistance to elevated temperatures, exist weak point, particularly lack flame retardant coating and fire-retardant filler; Secondly; Insulating barrier, lapping layer, the employed material of oversheath are good inadequately aspect the heatproof fire protecting performance, therefore, this type cable usually under adverse circumstances owing to can not high temperature resistantly influencing its operate as normal.
The utility model content
The purpose of the utility model provides a kind of high temperature resistant computer and uses shielded type cable, influences the problem of its operate as normal owing to resistance to elevated temperatures is relatively poor with computer cable in the solution prior art.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of high temperature resistant computer is used shielded type cable; It is characterized in that: include several cores; Every core constitutes by two groups of conductor pair twists that are coated with insulating barrier are wrapped, and every core is surrounded with the polyvinyl chloride lapping layer outward, extrudes in the said lapping layer to be filled with fire-retardant filler; Said lapping layer is coated with tinned copper wire braiding sub-shield; Several cores that are surrounded with sub-shield are coated with inner sheath, extrude in the said inner sheath to be filled with fire-retardant filler, and said inner sheath is coated with the wrapped total screen of copper strips, flame retardant coating, armour and oversheath outward successively.
Described a kind of high temperature resistant computer is used shielded type cable, it is characterized in that: said fire-retardant filler is a glass cord.
Described a kind of high temperature resistant computer is used shielded type cable, it is characterized in that: said flame retardant coating constitutes by mica tape is wrapped.
Described a kind of high temperature resistant computer is used shielded type cable, it is characterized in that: said armour is double-deck steel-tape armouring.
The beneficial effect of the utility model is:
The utlity model has good fire-retardant, high temperature resistant, anti-interference, performance such as transmission rate is fast, can adapt to different occasions, be specially adapted to the signal transmission of the computer automation system in long, high-temperature operation district of operating time.
