Further, the metallic spacer filling non-magnetic stainless steel band lock armo structure.
Further, the fire retardant anticorrosion environment-friendly type inner sheath fills ceramic crosslinked polyolefin insulating material.
The utility model has the advantages that in inorganic thermal insulation fireprotection layer compared with existing cable using ceramic SiClx
Rubber, it is nonhygroscopic, it is ensured that electric property can greatly improve the duration under flame, apply in cabling process inorganic
It is mineral-filled, flame retardant property is improved, there is fire resistance, is blazed up also nontoxic smokeless.The double-deck mineral insulation design, so that
Insulating properties inside and outside cable is more preferable, is optimal rank.Equipped with the double-deck mineral insulation, in addition inorganic thermal insulation fireprotection layer, so that
Cable has fire-proof insulation from inside to outside, has obtained multiple flameproof protection；And use Environmental-protective fire-proof nanometer mineral insulation material structure
At under rated voltage 2.5 times of excess load and insulating effect can be played as usual；Metal isolation is joined using non-magnetic stainless steel band
Sheathed structure is locked, there is superior mechanical, resistance to compression, antimagnetic, fire prevention, flexible, there are also have the effects that prevent pilferage, insect bite.It is anti-
Fiery anti-corrosion environment-friendly type inner sheath use ceramic polyolefine material, can be tied after burning porcelain, do not drip, smoke density is small, does not generate
Harmful gas simultaneously effectively keeps the internal structure of cable complete.
