Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1 copper core, 2 insulating barriers, 3 porcelain tendre layers, 4 lock armos, 5 mica tapes, 6 aluminium strips, 7 cable layer of paste, 8 oxide layers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of copper core fireproof power cable, including copper core 1,
The outer surface of copper core 1 is enclosed with oxide layer 8, and oxide layer 8 has pvc material to make, and has difficult combustion, acid and alkali-resistance, anti-micro-life
Thing, wear-resisting and have preferable warmth retention property and elasticity, the outer surface of oxide layer 8 is glued with aluminium strip 6, and aluminium strip 6 has airtight work
With, it is ensured that in cable, Integral sealing is improved, and the inside of aluminium strip 6 is coated with cable layer of paste 7, and cable layer of paste 7 has the effect of water suction,
