297,160. Hofmann, J. W. June 23, 1927. Drawings to Specification. Clamps for cables.-The parts of a clamp for suspending or straining electric cables which are in contact with the conductor are made of the same metal as the conductor, while the other parts are made of iron or steel. Corrosion between the clamp and the conductor due to electrolytic action is prevented, while the use of iron or steel enables the weight of the clamp to be reduced. Instead of using the same metal as the conductor, a metal near to it in the series of potential differences may be used. Specification 297,159 is referred to.
