In a few in-stances lightning hasbeen known to strikehigh-voltage lines,burn off one or moreconductors in themiddle of a span orslightly damage afew poles without af-fecting the insulat-ors. Often times when disturbances of this kind happennear a station in which are located trans-formers or similar apparatus, the voltagewill jump to ground either around theIcTiiiinal bushings or at some other pointwhere the distance will permit, withoutotherwise (hmiaf^ing llie api)ar;ilus in any.

Thepin-type insulatorhas about reached itslimitations,both elec-trically and mechani-cally, and the time isnot far distant whenthe manufacturerswill be forced to re-rate them on a moreconservative basis. The continuallyincreasing demandsof the general publicfor better servicewill compel utility ompanies to im-prove their facilitiesfor giving service bybuilding up andstrengthening the weak most long distance transmissionsystems too much attention has been de-voted to other parts of the system, leav-ing the economies to be made on theline. This has resulted in the use of tooshort poles, too light towers, insuiricientinsulation, etc., any one or all of whichway. false economies represent a saving in The suspension-type of insulator has first cost insignificant a
