This invention relates to the field of
power cable technology and provides an insulated
power cable including a conductor layer; the outer side of the conductor layer is provided with a buffer shielding layer, an
insulation layer, an insulation shielding layer, a braided reinforcement layer, a buffer repair layer, and a sheath layer in succession; the conductor layer includes a reinforcing core and an outer conductor one and an outermost conductor two, the cross-section of the conductor two being trapezoidal; the braided reinforcement layer includes an inner
braided composite layer and an outer braided layer, with anchoring units fixed at the intersection of the inner
braided composite layer and the outer braided layer; the buffer repair layer includes a
metal corrugated skeleton and an inner flexible
coating. The trapezoidal structure of the conductor two increases the contact surface, forming a heat dissipation channel in conjunction with the anchoring units. The composite braiding of the inner and outer braided
layers and the anchoring at the intersections quickly disperse external
impact forces. Simultaneously, the buffer repair layer enhances resistance to external forces, and repair microcapsules automatically fill defect gaps.
