Low-temperature crack-resistant reinforced power cable

Abstract

This invention discloses a low-temperature crack-resistant reinforced power cable, relating to the field of cable technology. A plurality of heat-absorbing insulation sheets are equidistantly laid on both the inner and outer sides of a high-flexibility insulation tube. Temperature-controlling heating tapes are symmetrically sleeved on the outer sides of the heat-absorbing insulation sheets. A plurality of anti-puncture steel strips are equidistantly bonded to the outer ends of the heat-insulating sleeves. A high-flexibility insulation sleeve is installed on the outer ends of the anti-puncture steel strips. A porous buffer sleeve with concave and convex shapes is sleeved on the inner side of the high-flexibility insulation tube. This invention effectively solves the problems in existing technologies where, due to damage to the protective layer and the cable relying solely on self-heating components for insulation, the cable suffers external freezing and hardening damage during prolonged operation, resulting in the consumption of large amounts of electrical energy. By employing two heating methods, temperature control is achieved while simultaneously providing self-maintenance to the cable's internal and external surfaces, preventing freezing and hardening damage, ensuring the stability of cable operation, and effectively utilizing the heat generated by the cable itself.
