Anti-/de-icing technologies have evolved into an integrated system combining active intervention and passive defense: DC de-icing (particularly MMC-based topologies) has become the mainstream active solution for high-voltage lines due to its high efficiency and low energy. Anti-/de-icing technologies have evolved into an integrated system combining active intervention and passive defense: DC de-icing (particularly MMC-based topologies) has become the mainstream active solution for high-voltage lines due to its high efficiency and low energy. Surfaces with poor hydrophobicity and high thermal conductivity, such as glass and metal, are especially prone to ice adhesion and buildup, including aluminum strand high voltage (HV) powerlines (figure 1). When overwhelmed with the weight of ice, the HV lines and towers can collapse, resulting in. Atmospheric icing (or simply icing) refers to freezing and sticking of water in various forms on the surface of an exposed object. Therefore, icing describes both ice and snow growth on exposed structures such as power network equipment. Icing can be classified into different categories: 1. Visual systems based on UAVs and fixed platforms have achieved breakthroughs in ice recognition and thickness retrieval, yet their performance remains constrained by image quality, data scale, and edge computing capabilities. These not only endanger the reliability of electrical grids by the loss of a power line for weeks or even months, but in general, the safety in the surroundings of the power line. As technology advances, we. Icing of transmission lines seriously affects the safety of the power sys-tem, and reliable anti-icing technologies guarantee the safe and stable operation of the power system.
