Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, the utility model provides a splicing type fireproof protective sleeve of an environment-friendly cable, which comprises a cable body 1 and fireproof protective sleeve bodies 2, wherein a heat insulation layer 3 is arranged on the inner wall of each fireproof protective sleeve body 2, a splicing layer 4 is arranged between each fireproof protective sleeve body 2, and a sealing strip 5 is movably connected to the outer surface of each splicing layer 4.

Wherein, insulating

layer
