Arc inner wall is bonded with inorganic mineral layer, and two pairs of curved metal sets are spliced into cylindric and copper conductor is wrapped in institute
In the cylindrical cavity of composition, the two sides of the curved metal set are provided with wedge groove, and the lumen loading of the wedge groove has
Mud is filled, the outer wall of the curved metal set is enclosed with mica tape, and the outer wall of the mica tape is arranged with embossing copper sheath, described
Embossing copper sheath is that multi-segment structure including the first body and the second body, first body, the junction of the second body are equal
It is provided with stepped groove, the metallic contact strips of more axial directions are connected between first body and the second body, the metal connects
Narrow bars are located in stepped groove, and the inner cavity of the stepped groove is wrapped with protection sleeve.
Preferably, the two sides of the curved metal set are provided with wedge groove, and the lumen loading of the wedge groove has filling
Mud.
Preferably, the filling mud and inorganic mineral layer are magnesia fire-proof mud.
The utility model proposes a kind of mineral insulated cable being easily recycled, beneficial effect is: passing through two pairs of setting
Curved metal set, curved metal cover inner wall and are bonded inorganic mineral layer, and inorganic mineral layer contacts realization insulation with copper conductor and prevents
The function of fire, comparison whole copper sleeve of existing use is set in copper conductor outer wall and inorganic mineral is filled in copper sleeve leads with copper
Mode between line convenient for copper sleeve to be realized to the function of recycling from copper conductor sur-face peeling, while embossing copper sheath being designed
At multi-segment structure, convenient for removing to embossing copper sheath, comparing existing mineral insulated cable has convenient for removing embossing copper
The advantages of sheath, inorganic mineral layer copper sheathing, realize the function being easily recycled.
