Described ceramic fiber paper is replaced by ceramic fiber blanket or ceramic fiber cloth or ceramic fibre strip.
Described fire lagging is that mica tape more than three layers or three layers is wrapped outside conductor.
Described waterproof insulating layer is at the silica gel porcelain band of outer wrapped more than two layers of fire lagging, plays waterproof fireproofing insulating effect.
Described fire prevention filler is high flame retardant glass fiber or ceramic fibre rope.
Described total screen adopts thin copper wire braiding, copper strips or the wrapped formation of aluminium foil, is installed on jamproof place.
Described flame retardant bed is ceramic fibre braid over braid or porcelain band, stops outside flame to combustion.
Described ring protection jacket layer selects environmental-friendly halogen-free low-smoke or silica gel material.
Described insulation crust is made up of mineral fibres.
The utility model patent compared with the existing technology, its advantage is: the construction of cable adopts sandwich construction parcel conductor to form, rational in infrastructure, the effect of fire prevention, waterproof can be reached, refractory temperature can reach 1000 degree, fire resistance period reaches 180 minutes, safe and reliable, can reach the user demand in ships cable; Fire prevention insulating layer wherein after ceramic fiber paper back adhesive glass fabric, bonds aluminium foil again form, refractory temperature is high, thermal insulation is effective, and quality of materials is light, quality is soft, decrease the weight of whole cable and the external diameter of cable, cable radius flexibility makes greatly the easy mounting and installation of cable and bends, convenient transportation; The material that each layer adopts is all ep-type material, and clean environment firendly is nontoxic, meet national environmental protection policy.
