Described packed layer is low smoke, zero halogen inserts.

Described oxygen barrier layer is ceramic silicon rubber oxygen barrier layer.

Described outer jacket is the anti-ant mouse of LSOH anti-flaming polyolefin jacket.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, conductor adopts 8000 series alloys conductors, and it has the characteristics such as high creep resistance, high-tensile, high-elongation, deadweight bearing capacity is strong, Corrosion Protection is good, high-flexibility, simultaneously switching performance safety and stability.This utility model product conductor adopts the aluminium alloy of the 2nd class formation to press stranded conductor wire core, and stranded conductor wire core makes it have stronger tensile property.

2, insulating material adopts 125 ℃ of IXPE to make, and IXPE is after electron beam to irradiate crosslinked, and mechanical performance improves greatly, guarantees that cable has excellent electric property, mechanical performance.The long-time running temperature of cable, at 125 ℃, is compared with common cable, and the physical and mechanical properties of cable is good, and ampacity improves greatly, and rise appreciably useful life.

3, " ceramic silicon rubber " is a kind of novel polymer composite, does oxygen barrier layer can guarantee the unimpeded of electric power, communication line the breaking out of fire in the situation that with it, the not short circuit of 90-180min of working, opens circuit the in the situation that of flame ablation; Ceramic silicon rubber oxygen barrier layer makes cable have high flame resistance, makes the be up to state standards category-A bunched burning test requirement of GB/T19666-2005 regulation of its fire resistance, has guaranteed the fail safe that cable is used under fire condition.

4, outer jacket adopts the anti-ant mouse of environment-protective halogen-free low-smoke flame-retardant polyolefin jacket material; can under-40 ℃ of low temperature environments, keep normal operation; in sheath, add termite-resistant rodent-resistant repellant; this material adopts and extracts from multiple natural plants; after repeatedly compound, add in cable sheath material; make cable jacket contain a kind of specific peculiar smell; after mouse ant class animal contact cable, because being upset, its sense of smell detests and rejects contact; Hai Huixiang colony sends impalpable information and produces population effect simultaneously, thereby reaches the object that protection cable is not destroyed by mouse ant.

5, all material of the utility model product all adopts LSOH anti-flaming material, has guaranteed cable loop guaranteed cost.Have when burning smoke density very low, non-corrosiveness gas is overflowed, and does not also produce harmful hydracid material, possesses the advantages such as low temperature resistant, high flame retardant and anti-ant mouse performance simultaneously, can be widely used in the more concentrated place of some personnel.
