Glass-fiber-fabric burn-out-proof layer outside moist fiber inner core.
The irregular isolating bar of cross-sectional shape is provided between the composite rope, the isolating bar is flame retardant epoxy
Propane is made.
The cross section of the ethylene propylene rubber insulated rope is diamond shape.
Between the copper foil polyester composite shielding band and mica insulation layer, ceramic polyolefin and mica insulation layer it
Between, between ceramic polyolefin and polytetrafluoroethylene (PTFE) flame-retardant layer be provided with flame retardant polypropylene fibers filled layer.
The beneficial effects of the utility model are: using the ceramic that between array cable core and cross section is in " 3 " shape is wound on
Polyolefin temporarily rapid curing can protect cable core is temporary not influenced by high fire as flame-retardant layer, in high fire, to need
The mechanical of operation provides one lifesaving time, and fire protecting performance is good；It is assumed diamond in shape using composite rope with cross section ethylene propylene rubber insulated
Restrict as tensile elements inside cable and one of fire-retardant, can be reduced in cable use internal stiffening bring run it is unsmooth
Problem；Cooperate the isolating bar of irregular shape to improve the stability inside cable simultaneously, extends cable life.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
