With few exceptions, ordinary wooden cross-arms are used; steel "wishbones" appear on but few lines. Steel bayonets and guard wires are common on many of the higher-voltage or more important lines. One company mounts the guard wire on glass insulators on the bayonets. Contrary to common belief, single-phase lines constitute but 21.4 percent of the total mileage; the remainder is all three-phase, and is all delta connected except for 237.75 miles. In general, with respect to the construction of the lines, it may be said that they are usually satisfactorily built, mechanically. The criticism to be made is that too many are well built, but not well engineered. A line may stand the stress of weather and look like a pretty decent job; it may even deliver the required power at the load end; but still true economy may be lost in construction, so that the resultant line losses or interest charges, if properly taken account of, may show the job to be a poor one, indeed, for the conditions under which it must serve.
