Abstract
The utility model relates to a kind of fireproof power cable, comprise cable core and fire retardant polyolefin oversheath, cable core is made up of the core of two and two above tape insulation layers, between core, fill anti-chamotte, wrapped ceramic silicon rubber composite band outside anti-chamotte, fire retardant polyolefin oversheath is wrapped in outside ceramic silicon rubber composite band.The beneficial effects of the utility model are: anti-chamotte, in fire-resistant, can prevent inner insulating barrier burning, and ceramic silicon rubber composite band, under the high temperature of burning, ceramic occurs, and closely wraps up anti-chamotte in protection cable core, prevents that anti-chamotte from coming off.This fireproof power cable can pass through category-A fire resistance test, and flame retardant effect excellence, and rate of finished products is high, and structural strength is high, and tensile property is good.
Description
Technical field
The utility model relates to a kind of fireproof power cable.
Background technology
Fireproof power cable refers to have that better fireproofing flame-resistant burns, flame-retarding power energy not, the power cable that still can maintain the operation of certain hour normal power-up in ablaze situation, it is used to important department and the public places such as skyscraper, subway, power plant, nuclear power station, tunnel widely.Traditional fire safe type power cable is Mica tape structure.This mica tape is to select phlogopite paper, organic siliconresin adhesive and alkali-free glass wool cloth, through gluing, bonding and cure and make.But the category-B fire resistance test that the fire-resisting cable of this fire-resistant layer structure can only specify by GB/T12666 standard, although existing ceramic silicon rubber fireproof power cable can pass through category-A fire resistance test, but it is low to compare common polyvinyl chloride power construction of cable intensity, and tensile property is poor.
Utility model content
Technical problem to be solved in the utility model is: a kind of fireproof power cable is provided, reaches the requirement of category-A fire resistance test.
The utility model solves the technical scheme that its technical problem adopts: a kind of fireproof power cable, comprise cable core and fire retardant polyolefin oversheath, cable core is made up of the core of two and two above tape insulation layers, between core, fill anti-chamotte, wrapped ceramic silicon rubber composite band outside anti-chamotte, fire retardant polyolefin oversheath is wrapped in outside ceramic silicon rubber composite band.
For further improving structural strength and tensile property, insulating barrier is polyvinyl chloride insulation layer.
The beneficial effects of the utility model are: anti-chamotte, in fire-resistant, can prevent inner insulating barrier burning, and ceramic silicon rubber composite band, under the high temperature of burning, ceramic occurs, and closely wraps up anti-chamotte in protection cable core, prevents that anti-chamotte from coming off.This fireproof power cable can pass through category-A fire resistance test, and flame retardant effect excellence, and rate of finished products is high, and structural strength is high, and tensile property is good.
Brief description of the drawings
Fig. 1 structural representation of the present utility model;
In figure: 1, fire retardant polyolefin oversheath; 2, core; 3, insulating barrier; 4, anti-chamotte; 5, ceramic silicon rubber composite band.
Embodiment
As shown in Figure 1, a kind of fireproof power cable, comprise cable core and fire retardant polyolefin oversheath 1, cable core is made up of the core 2 of two and two above tape insulation layers 3, between core 2, fill anti-chamotte 4, in the outer wrapped ceramic silicon rubber composite band 5 of anti-chamotte 4, fire retardant polyolefin oversheath 1 is wrapped in outside ceramic silicon rubber composite band 5.
Insulating barrier 3 adopts polyvinyl chloride insulation layer.
