For achieving the above object, this utility model provides following technical scheme: a kind of new waterproof insulate Cable, including core, the inside of described core is provided with inside insulating barrier and screen layer, and insulating barrier and sets Having inner insulating layer and external insulation layer, described inner insulating layer is joined directly together with external insulation layer and is connected into integrated knot Structure, at the conductor that is internally connected with of inner insulating layer, the outside of described external insulation layer connects has quasiconductor to hinder Water layer, connects in the outside of quasiconductor water blocking layer and has screen layer, and screen layer includes woven shield, Connecting in the outside of woven shield and have metal screen layer, the outside of described core connects packed layer, Connect in the outside of packed layer and have almag steel wire armor layer, outside almag steel wire armor layer Side connects styroflex layer, and the outside of described styroflex layer connects overcoat, and Overcoat is made up of sheath and outer jacket, and described sheath is located at inside outer jacket, described outer jacket Two ends be respectively connected with sheath, the top of sheath connects sealing lead, and connecting in the side of sheath has fiber crops to drape over one's shoulders Sheath.

As a kind of preferably technical scheme of this utility model, the outside of described styroflex layer connects It is connected to overcoat, and overcoat is made up of sheath and outer jacket.

As a kind of preferably technical scheme of this utility model, described sheath is located at inside outer jacket, The two ends of described outer jacket are respectively connected with sheath.

As a kind of preferably technical scheme of this utility model, the top of described sheath connects sealing lead, Connecting in the side of sheath has fiber crops to drape over one's shoulders sheath.

As a kind of preferably technical scheme of this utility model, the top of described outer jacket connects sealing lead Lid, connects on the surface of outer jacket and has earth lead.

Compared with prior art, the beneficial effects of the utility model are: this new waterproof insulated cable, By using almag steel wire armor layer, protection cable is not damaged by external force, has resistance to compression, tension Effect, safety is good, except normal power supply in flame, starts fire-extinguishing apparatus, reduces fire and damages Losing, simultaneously reliable to personal safety, its copper sheath is good conductor, is best earth lead, And continue to cable total length, and substantially increasing ground protection sensitivity and reliability, service life is long, Inorganic insulating material, high temperature resistant, and it is difficult to aging, there is volume advantage little, lightweight, structure Compact, save space, it is ensured that use the most energy-conservation, the safety of process, and efficiently, economical, just Victory, design is simple, with low cost, can be widely popularized use.
