In a further embodiment, the number of the inner insulating protection sleeves is four, the four inner insulating protection sleeves are uniformly arranged inside the dry packing layer, and the dry packing layer is arranged between the inner insulating protection sleeves and the anti-interference wrapping tape.

In a further embodiment, the insulating protective sheath port is provided with a ferrule, and the ferrule is provided in an aluminum structure.

In a further embodiment, two copper conducting cores are arranged inside the inner insulating protective sleeve, and the two copper conducting cores are arranged in a mutual transverse tangency mode.

In a further embodiment, the flame retardant layer is disposed between the tamper-evident tape and the metal armor layer.

In a further embodiment, the inside of the insulating protective sleeve is provided with a protective rib, and the protective rib is provided with a solid rubber structure.

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

1. the utility model discloses an insulating protective sheath's port department installs insulating protective sheath and can consolidate its port department, can avoid it to begin to warp by the port department, improves its regularity, is provided with the protection rib in insulating protective sheath's inside, makes the resistance to compression stretch-proofing ability of protective sheath improve greatly, effectively improves its life.

2. The utility model discloses an insulating protective sheath and fire-retardant layer between be provided with the metal armor, can wrap up the cable inner core through it, make the parcel comparatively inseparable, can avoid the inner core to warp, and be provided with the bayonet socket on the metal armor, make things convenient for the installation of metal armor to dismantle.
