An experimental study of dynamic icing process on an Aluminum-Conductor-Steel-Reinforced power cable with twisted outer strands

Ramsankar Veerakumar et al.

Summary: An experimental campaign was conducted to investigate the dynamic icing process and wind loads on an ACSR power cable under dry rime and wet glaze icing conditions. The icing process was recorded using high-resolution imaging, and the 3D shapes of the ice layers were quantified using a novel scanning system. The wind loads on the cable were measured using force/moment transducers and the evolution of the wake flow was analyzed using Particle Image Velocimetry (PIV). Differences were observed in the ice accretion and wind loads between the dry rime and wet glaze icing conditions.

Collision Characteristics of Water Droplets in Icing process of Insulators

Xingbo Han et al.

Summary: This paper investigates the collision process of supercooled water droplets on insulators and establishes a mathematical model using the boundary element method. The results show that the increase in wind velocity and droplet diameter leads to an increase in icing rate and area.
