Description
Technical field
The present invention relates to technical field of electric equipment, specially a kind of fire resisting electrical cable.
Background technology
With the continuous development of today's society economy, the performance of power equipment is also improving constantly, and user is to for passing
The requirement also more and more higher of the electrical cable for power of transmitting electricity.Electrical cable is as a kind of common electric utility, and its performance was in recent years
Also very fast lifting has been obtained.But traditional electrical cable electromagnetic radiation is larger, electromagnetic interference source is serious, and in transmitting procedure
Loss is very high, and electrical cable security on the market is low, and waterproof and fire resistance are poor, easily damages during outdoor application, it is impossible to
Meet the requirement in outdoor application cable to cable security performance.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of fire resisting electrical cable, to solve to propose in above-mentioned background technology
The problem of.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of fire resisting electrical cable, including outer jointing jacket and internal protective cover, the outer jointing jacket are made up of five layer materials, from
Flame resistant protective layer, polyvinylidene chloride protection film layer, screen layer, aluminium foil layer and rubber layer, the outer protection are followed successively by outside
Set is internally provided with herringbone frame, and the end of the herringbone frame is fixedly connected with rubber layer, the inside of the herringbone frame
Connect iron frame, be provided with internal protective cover in the arm support of the herringbone frame, and between herringbone frame and internal protective cover between
Elastic gel is also filled with gap, the internal protective cover is divided into two layers, and is followed successively by high strength fibre yarn layer, waterproof from outside to inside
Layer and flame retardant coating, the internal protective cover is internally provided with copper conductor, and the outer wrap of copper conductor has insulating barrier.
Preferably, the waterproof layer using the aluminium-plastic tape and AT sheaths of melten gel welding by being formed.
Preferably, the screen layer is worked out by aluminium wire, and the quantity of aluminium wire is 8 to 12.
Preferably, the copper conductor has four.
The beneficial effects of the present invention are：Most of electromagnetic radiation can be shielded, ensures that body during user's use is good for
Health, the high strength fibre yarn layer of setting improve the tensile strength of cable, the use of waterproof layer and flame resistant protective layer so that electrically
The waterproof and fire protecting performance of cable are further strengthened, and security performance improves, and meets the requirement of outdoor application.
