Specific embodiment
To keep the purposes, technical schemes and advantages of the technical program more clear, With reference to embodiment,
The technical program is further described.It should be understood that these descriptions are merely illustrative, rather than to limit this technology side
The range of case.
Embodiment 1
It is as shown in Figure 1, it is provided in this embodiment to extrude aluminium sheath mineral insulated cable, including by exterior layer to interior
Successively nested metal protection stratum reticulare 100, fire retardant insulating sheath 300 and outer layer extrudes aluminium sheath 300 to layer, and outer layer extrudes aluminium sheath
300 inside form accommodating cavitys, are equipped with the spaced lead unit of at least two groups in the accommodating cavity, and lead unit it
Between and lead unit and outer layer extrude the mineral-filled insulator 400 of the gap filling between aluminium sheath 300；
Lead unit include by outer layer to internal layer successively nested internal layer extrude aluminium sheath 540, fire-retardant insulated jacket 530,
Waterproof jacket 520 and conductor 510.
In the present embodiment, metal protection stratum reticulare 100 is aluminium alloy network management.Fire retardant insulating sheath 300 is polyvinyl chloride insulation
Sheath.Mineral-filled insulator 400 is magnesia powder.Fire-retardant insulated jacket 530 is fire-resisting ceramic silicone rubber.Waterproof jacket 520
For crosslinked polyethylene sheath.
The ratio of the diameter and lead unit diameter that accommodate cavity is greater than 3.
When lead unit quantity is greater than 3, the arrangement of lead unit circle column.
This fireproof cable is used through outer protective, is formed external metallization and is protected stratum reticulare 100, prevents animal from biting and destroy electricity
