Abstract

The utility model discloses a zero-halogen low-smoke cables flame-retardant medium-voltage fireproof cable, and the cable is provided with an insulating cable core. The interior of the insulating cable core is provided with conductors. The outer surfaces of the conductors are respectively provided with an insulating layer. The cable is special in that a plurality of filling cords are disposed in the gaps between the conductors in the insulating cable core; and the exterior of the insulating cable core is sequentially provided with a flame-retardant layer, an oxygen-isolating layer, a fire-isolating layer, a steel-tape armoured layer and an outer sheath from the inside to the outside. According to the utility model, the filling cords, the flame-retardant layer, the oxygen-isolating layer and the outer sheath generate non-poisonous gas during the breaking out of fire, and are good in light-admitting performance, thereby enabling persons at a scene of fire to clearly see the surrounding for rapid escape. The fire-isolating layer is disposed in the steel-tape armoured layer, so that heat can be quickly conducted through a steel tape during the breaking out of fire, thereby enabling the fire-isolating layer to become a ceramic housing. The hard housing can play a good role in flame retardation, fire resistance, fire prevention, and heat isolation. The cable can be used for supplying power for a period of time continuously during the breaking out of fire, thereby guaranteeing the safety of life and property.

Description

In LSOH anti-flaming, press fire-resisting cable
Technical field
The utility model relates to a kind of cable, particularly in a kind of LSOH anti-flaming, presses fire-resisting cable.
Background technology
Power cable is widely used in fields such as production, lives, is mainly used in the industries such as electric power, metallurgy, oil, chemical industry, building.There are two important problems in some places when fire occurs, and the one, when meeting fire, cable because burning produces a large amount of toxic smokes, Field Force can not be withdrawn safely and fast; The 2nd, when fire occurs, cable needs continued power a period of time, makes Field Force take in time corresponding measure guarantee personnel's life security and reduce property loss.So when fire occurs, guarantee power circuit within a certain period of time safe operation be very important.
Existing fire-resisting cable is mainly to adopt the halogen containing material such as flame-proof polyvinyl chloride, neoprene and chlorosulfonated polyethylene to reach as the sheath of cable the object that suppresses propagation of flame.These flame retardant cables can discharge a large amount of toxic smokes in burning, and smog block vision is brought certain difficulty to scene of fire escape; And poisonous gas suffocates people, jeopardize people's life security.
Summary of the invention
It is good that the technical problems to be solved in the utility model is to provide a kind of fire resistance, can be the in the situation that of breaking out of fire continued power a period of time, in the LSOH anti-flaming that gas is nontoxic, light transmission is good of generation, press fire-resisting cable.
Technical solution of the present utility model is:
In a kind of LSOH anti-flaming, press fire-resisting cable, there is an insulated wire cores, the built-in conductor of insulated wire cores, described conductor outer surface is provided with insulating barrier, its special character is: in the gap of insulated wire cores and conductor, be provided with many gasket for packings, the outer rim of insulated wire cores is provided with inhibiting tape, oxygen barrier layer, refuge floor, steel-tape armouring layer and oversheath from the inside to the outside successively.
Described gasket for packing is LSOH anti-flaming gasket for packing, the material of described oxygen barrier layer is low-smoke halogen-free flame-resistant polyolefin oxygen barrier CABLE MATERIALS, the material of described refuge floor is ceramic fireproof composite band, and the material of described oversheath is low-smoke and halogen-free flame retardant polyolefin jacket material.
The beneficial effects of the utility model are:
1, in this LSOH anti-flaming, press gasket for packing, inhibiting tape, oxygen barrier layer and the oversheath in fire-resisting cable, the gas producing when breaking out of fire is nontoxic, and light transmission is good, and scene of fire personnel can see environment around clearly, rapidly escape.
2, in LSOH anti-flaming, press refuge floor in fire-resisting cable in the inside of steel-tape armouring layer, when occurring, fire can pass through rapidly steel band heat conduction, make refuge floor form ceramic shell, hard housing can play better fire-retardant, fire-resistant, fire prevention, heat insulation effect; Continued power a period of time in the situation that of breaking out of fire, can better ensure the safety of life and property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-insulated wire cores, 2-conductor, 3-insulating barrier, 4-gasket for packing, 5-inhibiting tape, 6-oxygen barrier layer, 7-refuge floor, 8-steel-tape armouring layer, 9-oversheath.
Embodiment
As shown in the figure, in this LSOH anti-flaming, press fire-resisting cable, there is an insulated wire cores 1, built-in three conductors 2 of insulated wire cores 1, described conductor 2 outer surfaces are provided with insulating barrier 3, in the gap of insulated wire cores 1 and conductor 2, be provided with many gasket for packings 4, the outer rim of insulated wire cores 1 is provided with inhibiting tape 5, oxygen barrier layer 6, refuge floor 7, steel-tape armouring layer 8 and oversheath 9 from the inside to the outside successively.Described gasket for packing 4 is LSOH anti-flaming gasket for packings, the material of described oxygen barrier layer 6 is low-smoke halogen-free flame-resistant polyolefin oxygen barrier CABLE MATERIALS, the material of described refuge floor 7 is ceramic fireproof composite band, and the material of described oversheath 9 is low-smoke and halogen-free flame retardant polyolefin jacket materials.
