Definitions
- the present invention relates to a security cable, fire resistant and halogen-free, capable of working properly for a period of time given in fire conditions, without being propagating fire or generator of significant fumes or halogenated gases.
- These cables safety cables are in particular energy transmission cables or low frequency transmission, such as control or signal cables.
- JP-A-31 10713 discloses an electric cable comprising a fire resistant barrier between electrical conductor insulation and sheathing halogen-free electric cable.
- This barrier is produced by a ribbon containing sodium carbonate or sodium hydrocarbonate which emits carbon dioxide from around 400 ° C and has a self-extinguishing action on fire.
- WO 86/03 329 discloses the use of one or more taping containing glass fibers and / or mica, to make a barrier of fire resistance around an electrical conductor.
- compositions halogen-free and resistant to fire usable as insulation and / or sheathing in the field of cables electric.
- Patents EP-A-54424 and EP-A-82407 disclose such composition, comprising a mixture formed of a first elastomer component and a second plastomer component, a mineral filler containing a metal hydroxide, and optionally carboxylic groups.
- the proportion of metal hydroxide is 180 to 320% by weight relative to the weight of the mixing, making the composition fire retardant and non-propagating.
- thermoplastic composition of same type for the sheathing of a cable comprising a mixture of an elastomer and a plastomer and 150 to 250% by weight of metal hydroxide filler in the mixture.
- This mixture does not contain carboxylic acid groups related to said charge. It is formed from 20 to 35% by weight of copolymer polyethylene / vinyl acetate and from 65 to 80% by weight of copolymer ethylene / vinyl acetate.
- Document FR-A-2 241 580 discloses another composition similarly type, which comprises a polyethylene / ethylene-vinyl acetate copolymer, of hydrated alumina, a silicone elastomer and possible additives and agents coupling according to the required properties and which is crosslinked using a peroxide tertiary.
- the proportions by weight of hydrated alumina are from 25 to 150 parts, silicone elastomer from 2 to 25 parts and tertiary organic peroxide from 2 10 parts, per 100 parts of copolymer.
- Document GB-A-2 060 652 describes another composition of this same type, comprising an organic polymer, in particular an ethylene copolymer, a polysiloxane, a salt of a carboxylic acid of a Group II A metal and possible additives such as in particular silica and other retarding compounds of fire.
- Document FR-A- 2 601 377 discloses a composition also of same type, with ceramic forming agents.
- This composition comprises a polydiorgonasiloxane, in particular with methyl and vinyl groups, a reinforcing silica filler, a copolymer of siloxane and silica units and hydrocarbon groups, for example with methyl, ethyl, vinyl and phenyl groups, mica in the form of particles or pulverized, and an organic peroxide.
- the proportion of mica is 40 to 220 parts by weight per 100 parts by weight of the polydiorganosiloxane.
- Document FR-A-2 450 855 also discloses a composition fire resistant siloxane which converts to a resistant ceramic substance and homogeneous on exposure to temperatures above 500 ° C.
- This composition contains a ceramic filler which is chosen among a large number of such existing natural or synthetic fillers and used in the form of a fine powder to be dispersed in the composition.
- the proportion of ceramic filler can be 3 to 300 parts by weight in the composition. It is defined according to the ceramic property desired composition when exposed to high temperatures of a fire and the desired flexibility of this composition at temperatures normal use.
- compositions containing a filler of metallic hydroxide transforms into residual ash under the action of fire but do not allow the integrity of the cable to be preserved.
- the compositions containing a ceramic filler allow by against preserving the integrity of the cable. They are relatively high cost by compared to polyolefin compositions containing mineral fillers. They are also less flexible than the latter.
- the aim of the present invention is to improve the reliability of the behavior the fire of a safety cable, maintaining the resistivity as much as possible and the volume resistivity of the insulation composition, or minimizing the fall of these resistivities, while the insulation composition is exposed to the high temperatures of a fire.
- an electrical safety cable, fire resistant and without halogen comprising at least one electrical conductor, insulation around each conductor and an outer sheath, in which at least one of the parts components defined by the insulation of each electrical conductor and by the sheath exterior is made of a first composition made of a material polymer containing at least one ceramic filler and thus suitable to be converted at least superficially into the state of ceramic at high temperatures corresponding to fire conditions, characterized in that the insulation of each electrical conductor is alone carried out in said first composition, empty spaces are provided between said sheath and said insulation of each electrical conductor, and said sheath is produced in a second polyolefinic composition containing at least one metal hydroxide chage to burn completely and turn into residual ash under the action of fire.
- said second composition of said sheath comprises in addition an additional binder reducing the drop flow during its combustion but remaining insufficient for the transformation of said second composition in the state of ceramic under fire conditions.
- the polymeric material is a polysiloxane or an ethylene copolymer or a mixture of the two.
- the cables shown have two or three electrical conductors 1, insulation 2 around each electrical conductor and an outer sheath 3. This outer sheath provides empty spaces 4 between it and the isolated conductors it surrounds.
- the insulation 2 around each conductor is made of a polymer composition formed from a polysiloxane and / or a ethylene copolymer and containing in particular a formative filler of ceramic due to the high temperatures of a fire.
- the outer sheath 3 is in turn produced in a polyolefinic composition containing mineral fillers likely to turn into residual ash under the effect high temperatures of a fire.
- the empty spaces occupy at least 10% of the cable section. These empty spaces favor the complete combustion of this cladding subjected to fire, made of the presence of oxygen in these spaces, and the transformation of this cladding as residual ash coming off the insulation of the conductors. They prefer simultaneously the evacuation of part of the carbon contained in the compositions sheathing and insulation subjected to the high temperatures of the fire, under form of gas resulting from the combination of carbon and oxygen. This carbon thus evacuated does not settle on the insulation, while this passes to the less superficially in the state of ceramic. However, it was noted that this presence of carbon in the cable during its combustion has an influence decisive and harmful on the volume resistivity and the surface resistivity of insulation of electrical conductors. The decrease in the amount of carbon present in the cable during its combustion allows the maintenance of its resistance isolation to a level sufficient for it to continue to function properly.
- the combustion thus favored of this cladding and its complete and relatively rapid transformation into residual ash means that the insulation quickly passes at least superficially to the state of ceramic and therefore ensures the maintenance of the physical integrity of the cable under the conditions of fire.
- the duration of the transitional phase between 400 to 600 ° C is reduced by this transformation at least superficial in the ceramic state, to minimize possible macrocracks which may appear during this phase transient.
- This complete combustion of the cladding in polyoffinic composition takes place at low emission of toxic fumes and gases and without propagation of the fire.
- the cladding composition can also include a binder, in particular a ceramic filler then used in low proportion in the sheathing composition, to avoid the drop flow during its combustion and thus avoid a possible spread of fire but without leading to a change in the state of this composition in ceramic.
- a binder in particular a ceramic filler then used in low proportion in the sheathing composition, to avoid the drop flow during its combustion and thus avoid a possible spread of fire but without leading to a change in the state of this composition in ceramic.
- the desired presence of empty spaces between the insulation of each electrical conductor and the sheathing of the cable leads to a gain of the quantities of the composition which is used for the sheathing not coming fill natural spaces in a multi-conductor cable structure isolated. The cost and the release of smoke and gas are thereby reduced.
