Description
Technical field:
The utility model relates to a kind of computer cable, the dynamo-electric cable of particularly a kind of high temperature resistant pair twist SHIELDING CALCULATION.
Background technology:
Existing computer cable ubiquity defective aspect high temperature resistant is that the materials used of lapping layer all is that polyethylene film or tetrafluoroethene film are made on the one hand, and polyethylene can not be high temperature resistant, can't normally use under hot environment; Polytetrafluoroethylene at high temperature can discharge pernicious gas, causes environmental pollution.On the other hand, lack flame retardant coating, there is defective in the cable that uses a computer aspect fire prevention.
Summary of the invention:
The purpose of this utility model is at the problems referred to above, designs a kind ofly in adverse circumstances, especially can guarantee the dynamo-electric cable of the normal high temperature resistant pair twist SHIELDING CALCULATION of using in hot conditions.
The technical solution of the utility model: the dynamo-electric cable of a kind of high temperature resistant pair twist SHIELDING CALCULATION, it comprises: flexible conductor, insulating barrier, pair twist group lapping layer, pair twist component screen, total lapping layer, flame retardant coating, total screen, external sheath layer, it is characterized in that, flexible conductor is surrounded by insulating barrier outward, constitutes heart yearn; Per two heart yearns strand constitutes the heart yearn group together, and every pair of heart yearn group is surrounded by pair twist group lapping layer outward, and pair twist group lapping layer is surrounded by pair twist component screen outward, constitutes the conductive core line group.The conductive core line group is surrounded by total lapping layer outward, and lapping layer is surrounded by flame retardant coating outward, and flame retardant coating is outward total screen, and total screen is outward a sheath, constitutes whole cable.
Wherein, described flexible conductor adopts multiply tin-coated copper tow.
Wherein, described insulating barrier is a crosslinked polyethylene.
Wherein, described pair twist component screen forms by aluminum-plastic composite membrane is wrapped.
Wherein, described total screen is formed by the copper wire braiding.
The beneficial effects of the utility model:
1, has low toxicity, low cigarette, Halogen or characteristics such as low halogen, flame-retarding cleaning.
2, have low electric capacity, low inductance.
3, this utility model is provided with the screen of one deck copper wire braiding between high temperature resistant lapping layer and sheath, makes this cable have good shield effectiveness and interference free performance.
Description of drawings:
Fig. 1 is a schematic cross-section of the present utility model.
