AI Technical Summary
The poor thermal conductivity of existing mica tape leads to high conductor operating temperatures or reduced maximum allowable current carrying capacity in cross-linked polyethylene insulated cables, and cannot effectively solve the problem of poor thermal conductivity of mica tape.
Using MgO/γ-Al2O3 composite filler as the main component of the binder, a core-shell structure of MgO core and γ-Al2O3 shell is prepared by ball milling to improve the thermal conductivity and insulation properties of mica tape, and to generate a stable ceramic barrier at high temperature to enhance fire resistance and flame retardancy.
It significantly improves the thermal conductivity and insulation of mica tape, enhances the heat dissipation capacity and fire resistance of the cable, and ensures the stable operation of the cable under high temperature conditions.
