Abstract
The utility model discloses a halogen-free low-smoke flame-retardant fire-resistant medium-voltage flexible cable, which comprises flexible-structured conductors, and a semi-conductive tape layer, a conductor shielding layer, an XLPE insulation layer, an insulation shielding layer and a copper-wire-braided shielding layer sequentially coating the flexible-structured conductors. A ceramic silicone rubber layer and a halogen-free low-smoke flame-retardant sheath layer are also arranged sequentially outside the copper-wire-braided shielding layer; and an alkali-free glass fiber tape layer is also arranged between the ceramic silicone rubber layer and the halogen-free low-smoke flame-retardant sheath layer. In the case of fire, the external ceramic silicone rubber layer in a fire-resistant structure is changed into a fire-resistant basic layer in a ceramic structure after heating, the inner structure can be firmly wrapped, roles of oxygen insulation and heat insulation can be played, normal power supply can be ensured, and valuable time can be provided for escape and property rescue.
Description
Technical field
The utility model relates to a kind of middle pressure flexible cable, especially relates to the fire-resistant middle pressure flexible cable of a kind of LSOH anti-flaming.
Background technology
Along with the development of Urban Construction in China, the gradually rising of electricity capacity, the buildings such as high-rise, super-huge market, tunnel are increasing to the demand of power cable.At present the structure of common cable general mainly comprises the soft structure conductor, sequentially is coated on this soft structure conductor outer semiconductive belting layer, conductor shield, XLPE insulating barrier, insulation screen and proof copper-wire braided screen, the common cable of said structure does not have fire-resistant performance, when breaking out of fire, insulating barrier will soon be burnt, cause short circuit power cut, make troubles to escape.
The utility model content
The technical problems to be solved in the utility model provides a kind of fire-resistant middle pressure flexible cable of LSOH anti-flaming with good fire resistance.
For solving the problems of the technologies described above, the fire-resistant middle pressure flexible cable of the utility model LSOH anti-flaming, comprise the soft structure conductor, sequentially be coated on this soft structure conductor outer semiconductive belting layer, conductor shield, XLPE insulating barrier, insulation screen and proof copper-wire braided screen, described proof copper-wire braided screen also sequentially is coated with ceramic silastic-layer and LSOH anti-flaming restrictive coating outward.
As further improvement of the utility model, also be provided with the alkali-free glass fiber belt between described ceramic silastic-layer and the LSOH anti-flaming restrictive coating.
Adopt the fire-resistant middle pressure flexible cable of LSOH anti-flaming of said structure, because described proof copper-wire braided screen also sequentially is coated with ceramic silastic-layer and LSOH anti-flaming restrictive coating outward, when breaking out of fire, its outside fireproof construction ceramic silastic-layer is after being heated, can be transformed into the fire-resistant basic unit of one deck ceramic structure, internal structure is wrapped up firmly, play oxygen barrier, heat insulation effect, guarantee normal power supply, provide the valuable time for escaping and rescuing property; This cable has the LSOH anti-flaming restrictive coating, and when cable during in the calcination that is subject to flame, itself does not prolong combustion, and the amount of being fuming is very low simultaneously, and a small amount of produce be nontoxic gas, can not cause secondary injury; Owing to also be provided with the alkali-free glass fiber belt between described ceramic silastic-layer and the LSOH anti-flaming restrictive coating, further strengthened the fire-resistant effect of cable in addition.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the cross-sectional view of the fire-resistant middle pressure flexible cable of the utility model LSOH anti-flaming.
Embodiment
Referring to Fig. 1, the fire-resistant middle pressure flexible cable of the utility model LSOH anti-flaming, comprise soft structure conductor 1, sequentially be coated on this soft structure conductor 1 semiconductive belting layer 2, conductor shield 3, XLPE insulating barrier 4, insulation screen 5 and proof copper-wire braided screen 6 outward, also sequentially be coated with ceramic silastic-layer 7 and LSOH anti-flaming restrictive coatings 8 outside the described proof copper-wire braided screen 6.
Can also be provided with alkali-free glass fiber belt (9) between described ceramic silastic-layer 7 and the LSOH anti-flaming restrictive coating 8.
Claims (2)
1. fire-resistant middle pressure flexible cable of LSOH anti-flaming, comprise soft structure conductor (1), sequentially be coated on this soft structure conductor (1) outer semiconductive belting layer (2), conductor shield (3), XLPE insulating barrier (4), insulation screen (5) and proof copper-wire braided screen (6), it is characterized in that: outer ceramic silastic-layer (7) and the LSOH anti-flaming restrictive coating (8) of also sequentially being coated with of described proof copper-wire braided screen (6).
2. the fire-resistant middle pressure flexible cable of LSOH anti-flaming as claimed in claim 1 is characterized in that: also be provided with alkali-free glass fiber belt (9) between described ceramic silastic-layer (7) and the LSOH anti-flaming restrictive coating (8).
