Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of mineral insulated cable with stronger high temperature-proof, including two cable hearts 3 and housing 1,
Two cable hearts 3 are located at the inner cavity of housing 1, and two cable hearts 3 are centrosymmetric compared with the axis of housing 1 to be arranged inside housing 1,
Housing 1 is mixed using insulating materials with steel, and the inside of housing 1 sets the first adhesive layer 7, the first adhesive layer 7
Inside is provided with reinforcing layer 2, and the inside of reinforcing layer 2 is provided with the second adhesive layer 8, and the outer sheath of the cable heart 3 is equipped with cooling layer 6, drop
Warm layer 6 is internally provided with several cooling pipes, and cooling pipe is arranged compared with 3 center of circle circular array of the cable heart, the outside for the layer 6 that cools down
Be arranged with fireprotection layer 5, fireprotection layer 5 is the insulated wire cores thermal insulation layer of high molecular halogen-free silicon porcelain cement, by fireprotection layer 5 for macromolecule without
The setting of the insulated wire cores thermal insulation layer of halogen silicon porcelain cement can strengthen the fire protecting performance of the mineral insulated cable, the outside of fireprotection layer 5
Equipped with the 3rd adhesive layer 9, the first adhesive layer 7, the second adhesive layer 8 and the 3rd adhesive layer 9 are epoxy resin, pass through the first bonding
The 7, second adhesive layer 8 of layer and the 3rd adhesive layer 9 are the setting of epoxy resin, can strengthen mineral insulated cable connection
