INSULATOR STRINGWITH RING SHIELDAND ARCING HORN F\g. 2 The fundamental weakness of the multi-part suspension insulator in its present formis the fact that the electrical strength of anyunit is much below the total voltage ap-plied, and no positive means exist for con-trolling the distribution of this voltageamong the several units. For parts requiring rigid support pillartype insulators are available consisting ofseveral multipart units. These units indi-vidually have much higher flashover valuesthan the suspension units. A typical flash-over value is 185 kv. dry and 145 kv. wet.Observation indicates better performance ofthese insulators in a given length than ofthe standard suspension units. 2—Corona Another important practical problem isthe selection of a size of conductor that will avoid excessive energy loss into the air byreason of the electrical overstress of the airsurrounding the conductor. This phe-nomena called corona has been recognizedfor many years and has been the subj
