Bricks Test Storm Resistance of Phone Wires (Mar, 1941)

Bricks Test Storm Resistance of Phone Wires
To determine how well telephone wires will carry the extra weight of ice during snow and sleet storms, engineers string bricks along experimental open-wire lines at the Bell Laboratories field station in Chester, N. J. It has been found that an accumulation of ice one inch in radial thickness adds about twenty-two ounces to a foot of wire, or 200 pounds on a 150-foot span.
