National surveys show consumers’ mood is brightening, and it’s not just holiday cheer. The more positive outlook has a lot to do with the steep drop in gasoline prices since last summer. 2015 holds the promise of more price relief not only at the gas pump but also at grocery stores.
Damaged Insulation Led To Underground Explosions In Columbus
American Electric Power says explosions that sent manhole covers flying in downtown Columbus last February happened when insulation material on electricity cables broke down because of water, salt and other factors.
Nobody was injured in the explosions that sent two manhole covers into the air and shattered one.
The utility is spending around $30 million to prevent any similar explosions.
AEP says the cracked insulation exposed metal wires to the air and the high level of electricity running through the cables produced heat. That caused the rubber insulation to burn, releasing a flammable gas.
The utility says the gas built up inside a small vault that holds electricity equipment and the heat and electricity likely led to a spark that caused the explosion.
