This winter’s phenomenon popularly known as a “polar vortex” has kept many of us around the world under a blanket of snow and ice and well below freezing temps — hitting -23°F below zero in Chicago! Despite the freezing temps, there’s still work to be done – cable plants to install and permanent links to test. But installing and testing cable plants isn’t always easy when it’s so bitter cold! Cold temperatures can make for stiff, inflexible cable that is more difficult to install. And if the cables aren’t pulled at or above recommended temperatures, PVC jackets can potentially crack during the rigors of installation.
