Said heat-resisting aluminium alloy silk cross section is circular or oval.
Can also comprise the high flame retardant inner covering, said high flame retardant inner covering is positioned at outside the high temperature resistant band lapping layer, in the S type self-locking armour.
Optimal technical scheme: porcelain fire-resistant silicon rubber insulating barrier is coated on the heat-resisting aluminium alloy conductor and forms cable core outward; Article 4, fill high temperature resistant packing material between cable core; Fill high temperature resistant packing material between cable core and the high temperature resistant band lapping layer; High temperature resistant band lapping layer is outward the high flame retardant inner covering, and the high flame retardant inner covering is outward a S type self-locking armour, and outermost layer is a porcelain fire-resistant silicon rubber outer jacket.
The utility model is to be cable core with the heat-resisting aluminium alloy stranded conductor that is coated with porcelain fire-resistant silicon rubber insulating barrier, is filled with high temperature resistant packed layer between each core, and the outside has high temperature resistant band lapping layer, fire-retardant inner covering, S type self-locking armour and outer jacket successively.The utility model is to be conductor with the aluminium alloy, and ampacity is than big many of general aluminium cable, can be near the ampacity of copper, thereby can replace copper cable, thus practice thrift a large amount of valuable copper resources.With the porcelain fire-resistant silicon rubber is insulating barrier, any fire-resisting cable that cost performance is superior to existing in the market.Fire resistance and mechanical performance are superior to existing any fire-resisting cable.The utility model adopts heat-resisting aluminium alloy conductor good bandability, and the bounce-back rate is low, high temperature resistantly is difficult for scorification and breaks, and the utlity model has fire-resistance property, and when fire took place, the porcelain fire-resistant silicon rubber outer jacket porcelainization of being heated stoped further carrying out of burning.
S type self-locking armour not only plays fire-retardant effect when fire takes place; And after the outer jacket porcelainization; The self-locking armour of S type is embedded in the porcelain fire-resistant silicon rubber outer jacket, links porcelain fire-resistant silicon rubber outer jacket, because the existence of self-locking armour; Electric wire can be not cracked because of embrittlement, avoids the heat-resisting aluminium alloy silk exposed by scorification.Under normal circumstances, S type self-locking armour can also play the effect of reinforcement protection, and electric wire can be crooked easily, the buckling work requirement under the suitable complex environment.
Compared with present technology the utility model is described further, the utility model have obvious technical advantage:
1, current-carrying capacity of cable is a times of copper model aluminium 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.
6, cable has S type self-locking armour, withstand voltagely, anti-pounds, tension, and fire resistance is better.
