Description

A kind of soft PE alloy cable of the fire-retardant radioprotective that blocks water

Technical field

This utility model relates to alloy cable technical field, is specially the soft PE alloy cable of a kind of fire-retardant radioprotective that blocks water.

Background technology

The development of economic society, has promoted the development in city. Urban architecture, along with the development in city, constantly develops to maximization, High Level and densification direction. And the personnel's highly dense in building, the harm of fire, floods is continuously increased. People often live near high tension cable, and health also can bear very big electromagnetic radiation, and the existing construction of cable is simple, not there is the function of fire protection flame retarding and waterproof, and when mounted, the bending coefficient of cable is relatively big, when carrying out straight line and laying, can not meet design requirement, waste a part of cable, according to copper conductor structure in copper pipe sheath, the restriction being subject to copper pipe length of this structure, erection joint is many, and joint hidden danger is big. Cable Unit Weight weight, is unfavorable for long length vertical run. Meanwhile, all adopting copper conductor, copper pipe sheath, inorganic oxide magnesium to insulate, manufacturing cost is high, is unfavorable for extensive use.

Utility model content

The purpose of this utility model is in that to provide the soft PE alloy cable of a kind of fire-retardant radioprotective that blocks water, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme: the soft PE alloy cable of a kind of fire-retardant radioprotective that blocks water, including PE oversheath, the inner chamber of described PE oversheath is installed with armouring, the inner chamber of described armouring is fixedly connected with rib, the inner chamber of described rib is filled with plastic foamed packed layer, the inner chamber of described plastic foamed packed layer is fixedly connected with outer semiconductor screen layer, the inner chamber of described outer semiconductor screen layer is fixedly connected with soft copper conductor, the inner chamber of described soft copper conductor is enclosed with interior semi-conductive shield, the inner chamber of described interior semi-conductive shield is fixedly connected with insulating barrier, in the inner chamber of described insulating barrier, fixed packet is wrapped with alloy conductor.

Preferably, described rib is fixing with outer semiconductor screen layer is connected.

Preferably, described plastic foamed packed layer and rib are at least provided with 10 groups, and are evenly distributed on the outside of outer semiconductor screen layer.

Preferably, described soft copper conductor is circumferential array, is evenly distributed on the outside of interior semi-conductive shield.

Compared with prior art, the beneficial effects of the utility model are: this utility model close structure, and production cost is low, enhance the pliability of cable, anti-radiation and anti-flammability, improve the service life of alloy cable. by arranging PE oversheath, cable can be stoped to ignite, it is effectively protected the structure within cable to be damaged from, reduce the economic loss that disaster causes, by arranging armouring, tensile strength can be increased, comprcssive strength and to cable protection, increase the service life, cable interference free performance can also be improved and pass through shielding protection, by arranging inside and outside semi-conductive shield, the electric field that can produce in shielded cable, it is possible to prevent electric current to leak simultaneously, play safe effect, by arranging rib and plastic foamed packed layer, the pliability of cable can be improved, when laying, the waste of cable can be avoided, effectively save production cost.
