ice load

ice load

[′īs ‚lōd]
(engineering)
The weight of glaze deposited on an overhead wire in a power supply system; standard safety codes require allowance for ½-inch (12.7-millimeter) radial thickness in heavy loading districts and ¼-inch (6.35-millimeter) in medium.

The models can be used to check for structural deformities that may have been caused by excessive stress and the surface area of components can be measured for wind and ice load calculations, allowing for well-informed decisions that no longer rely solely on the person climbing the tower.
Scientists from Finland [2], Sweden [3], Japan [4], Spain [5], United States of America [6] and others studied the ice load on a vertical structure, but these works focus on the formation of sea ice.
With an increased surface area, more ice can accumulate on lateral branches; the greater ice load results in greater chance of branch failure."
Equation (3) shows the ICE torque divided into ICE load torque and ICE friction torque.
In the higher latitudes, ice load is taken as design control load based on estimation.
Heavy snow or ice load can weigh down branches, causing fractures of limbs.
Furthermore, the primary environmental load considered in the design of transmission structures is the wind load, although the ice load may govern the design of transmission tower-line systems in some cold regions.
So, through the displacement excitation of wires, the ice can effectively be removed; in addition to the fact that the wire ice coating belongs to brittle material, alternating stress and displacement can significantly improve the efficiency of deicing and reduce the transmission lines ice load to the its allowance.
The ice load downed numerous trees, branches, and power lines which resulted in widespread power outages.
This results in a reduction of 25% of the total ice load.
"They can withstand 100-mile-an-hour winds and take a half-inch ice load."
Concentrations of certain elements in the rock suggest that mantle melting doubled when the ice load disappeared, they report.
