What adopt both at home and abroad is the fire-resisting cable that magnesia mineral fire-proof insulation cable and mica tape twine mostly; The production and processing of magnesia mineral fire-proof insulation cable is can not image height molecular material that kind convenient; Need special import equipment, the laying installation difficulty is big, and cost of raw material cost is high; Be difficult to popularize on a large scale use, be difficult to especially on civil buildings, promote etc.And the fire-resisting cable that mica tape twines needs multi-lay winding in process of production, because the restriction of process conditions; Often be prone to cause overlapping the slot place defective to occur; Burn back mica tape embrittlement, come off easily, also cause fire-resistant weak effect; Thereby be difficult to ensure safe and smooth under fire condition of communication, electric power, fire-resistant weak effect.
The utility model content
In order to overcome deficiencies such as existing cable amount of copper consuming high-fire resistance difference, the purpose of the utility model is: a kind of aluminium alloy conductor porcelain fire-resistant silicon rubber insulated cable is provided.
It is following that the utility model solves the technical scheme that its technical problem adopted: a kind of aluminium alloy conductor porcelain fire-resistant silicon rubber insulated cable, and it comprises cable core, glass fiber filling part, heat-resistant fireproof glass strap lapping layer, porcelain fire-resistant silicon rubber outer jacket; Filled glass fiber filling part between cable core and the heat-resistant fireproof glass strap lapping layer, outermost layer is a porcelain fire-resistant silicon rubber outer jacket.
Said cable core is more than one or 1, filled glass fiber filling part between each cable core.
Said cable core is made up of heat-resisting aluminium alloy conductor and porcelain fire-resistant silicon rubber insulating barrier, and said porcelain fire-resistant silicon rubber insulating barrier is coated on outside the heat-resisting aluminium alloy conductor.
Said heat-resisting aluminium alloy conductor adopts single heat-resisting aluminium alloy silk, or, press or the non-heat-resisting aluminium alloy conductor that constitutes that presses by multiply heat-resisting aluminium alloy silk; Said heat-resisting aluminium alloy silk cross section is a regular shape.Said heat-resisting aluminium alloy silk cross section is preferably circle or ellipse.
Can also comprise fire-retardant inner covering, said fire-retardant inner covering is positioned at outside the heat-resistant fireproof glass strap lapping layer, in the porcelain fire-resistant silicon rubber outer jacket.
Can also comprise armour, said armour is positioned at outside the heat-resistant fireproof glass strap lapping layer, in the porcelain fire-resistant silicon rubber outer jacket.
Porcelain fire-resistant silicon rubber insulating barrier is coated on the heat-resisting aluminium alloy conductor and forms cable core outward; Article 4, filled glass fiber filling part between cable core; Filled glass fiber filling part between cable core and the heat-resistant fireproof glass strap lapping layer; Heat-resistant fireproof glass strap lapping layer is fire-retardant inner covering outward, and fire-retardant inner covering is outward an armour, and outermost layer is a porcelain fire-resistant silicon rubber outer jacket
The utility model is to be conductor with the aluminium alloy, because conductor all can be high temperature resistant with insulation, overload capacity is strong; Can replace copper cable, thereby practice thrift a large amount of valuable copper resources.With the porcelain fire-resistant silicon rubber is insulation, any fire-resisting cable that cost performance is superior to existing in the market.The cable appearance is an outer jacket.
The utility model structurally has evident characteristic:
The utility model cable adopts the single aluminium plying of heat-resisting aluminium alloy or strands presses or non-compact conductor, and refractory glass fibre is a packing material, and lapping layer is the refractory glass fibre inhibiting tape.
Compared with present technology, the utility model has obvious technical advantage:
1, the long-term overload capacity of cable is than high many of existing power cable.
2, the refractory insulating layer of the utility model is can the potteryization fire-resistant silicon rubber being insulation; Through high temperature or flame calcination the time, insulation can be formed resistant to elevated temperatures solid ceramic, and has the excellent electric insulating ability; Can guarantee cable normally operation in flame; Can bear the spray of certain water and the vibrations of certain intensity, can guarantee that circuit does not rupture not short circuit.
3, the material environment friendly that the utility model adopted is nontoxic, and has the favorable mechanical performance.
4, the utility model is compared with common fire-resisting cable with mineral insulated cable in the past, has to be prone to produce, to be prone to install and characteristics such as cost performance height.
5, the utlity model has that ampacity is big, operating temperature is high, cable is flexible and difficult generation scholar becomes.
