Brief description of the drawings
Fig. 1 is a kind of structural representation of fire-proof and explosion-proof power cable proposed by the present invention.
Embodiment
As shown in figure 1, Fig. 1 is a kind of structural representation of fire-proof and explosion-proof power cable proposed by the present invention.
Reference picture 1, a kind of fire-proof and explosion-proof power cable proposed by the present invention, including：Cable core, lapping layer 5, screen layer 6, every
Absciss layer 7, embossing metallic sheath 8, restrictive coating 9；
Cable core includes multiple conducting wires, and each wire includes the conductor 1 positioned at middle part, the interior insulation being coated on outside conductor 1
Layer 2, the middle insulating barrier 10 being coated on outside inner insulating layer 2, the external insulation layer 3 being coated on outside middle insulating barrier 10, inner insulating layer 2
Formed using mica tape cladding, middle insulating barrier 10 is formed using polyester belt cladding, and external insulation layer 3 uses ceramic silastic material system
Into；
Lapping layer 5 is coated on outside cable core, and screen layer 6 is coated on outside lapping layer 5, and separation layer 7 is coated on outside screen layer 6
Portion, embossing metallic sheath 8 are coated on outside separation layer 7, and restrictive coating 9 is coated on outside embossing metallic sheath 8.
In the present embodiment, the fire-proof and explosion-proof power cable proposed, cable core include multiple conducting wires, and each wire includes position
Conductor in middle part, the inner insulating layer being coated on outside conductor, the external insulation layer being coated on outside inner insulating layer, inner insulating layer are adopted
Formed with mica tape cladding, external insulation is made of ceramic silastic material, and lapping layer is coated on outside cable core, screen layer cladding
Outside lapping layer, separation layer is coated on outside screen layer, and embossing metallic sheath is coated on outside separation layer, and restrictive coating, which is coated on, to be rolled
Outside line metallic sheath.By the fire-proof and explosion-proof power cable of above-mentioned optimization design, structural design optimization is reasonable, is provided with outside conductor
Three layers of fire-proof insulation, while ensureing insulating properties, ensure fire retardant performance, meanwhile, metallic sheath is set outside cable core, without
Extra poling insulation blocking, can be mounted directly laying by metallic sheath, alleviate installation strength, improve installation effectiveness.
In the design of wire, wrapped mica tape insulating barrier, reaches this fireproofing of cable purpose, then in cloud on conductor
Wrapped polyester belt insulating barrier on master tape insulating barrier, because polyester belt has preferable insulating properties and mechanical performance, can make up cloud
The deficiency of master tape insulating properties, while mica insulation layer is protected by, prevent mica powder piece from coming off and influenceing fire protecting performance.Most
The wrapped Ceramic silicon rubber tape insulation layer on polyester belt insulating barrier afterwards.Ceramic silicon rubber tape insulation performance is fine, about 450
DEG C start to be hardened and form ceramic-like housing, in case of fire, the ablation time is longer, and temperature is higher, the ceramic-like housing of formation
