The beneficial effects of the utility model are as follows:
The utility model is compact-sized, reasonable, by the shielded layer of cable, replaces copper material with new material alloy material, reduces
The weight of material, reduces costs, while cable being made to lighten；Using the material-structure of good flame retardation effect, so that the resistance of cable
Combustion property fire resistance greatly improves.It is specific as follows:
1, the utility model with copper-clad aluminum alloy wire material by replacing copper wire, Nanoalloy band to replace copper for shielded layer
Band, the suitable situation of electrical property, the weight saving of cable about 10%~20%, cable cost reduce by 8%~15%.
2, the utility model uses fire-retardant fireproof separation layer, and the heat-insulated solidified mud of the mineral is encountered with softness under room temperature
High temperature starts the characteristic of cure hard, does not burn and not thermally conductive, therefore flame-retardant is preferable.In the case of fire, one is formed
The hard protection shell of layer, fire-retardant flame are inwardly spread, and play the role of anti-flaming thermal-insulation, cable can be in 750 DEG C~950 DEG C flames
Lower normal operation 90min or so when encountering fire, brings prime time to escape and rescue.
3, oversheath has certain anti-flammability using the high resistant combustible material extruded, material, in the case of fire, has very well
Longitudinal anti-flammability if cigarette is few nontoxic using LSOH anti-flaming material, and when fire be a kind of environment-friendly materials, fire occurs
When burning, it is conducive to personnel escape.
4, split-phase shielded layer uses aluminum-alloy wire braid shielded, and total shielded layer uses the wrapped shielding of Nanoalloy band, this
The structure of split screen aggregation screen, can be reduced the mutual crosstalk and external disturbance between circuit, so that computer cable not only has well
Flame retardant effect, there are also preferable shield effectiveness, while there are the advantages such as light-weight, at low cost.
