Electrical Cable Classification Pdf. Stranded core wire for a given gauge stranded wire withstands flexing more than its solid core equivalent. The triplex service drop cable is a three core conductor. However the classification of cables on the basis of voltage is more common according to which they can be divided into the following categories.
Classified or verified wire and cable see appendix a for designations. Classification based upon voltage rating of the cable. Electrical cable classification according to voltage. Automatic voltage regulator avr for generator.
Stranded wire is best suited where frequent flexing or vibration is more likely to occur e g.
The triplex service drop cable is a three core conductor. Solid class 2 stranded class 5 flexible class 6 extra flexible mostly used for cords and welding etc. Usually the operating voltage determines the type of insulation and the cables are placed in various. High voltage or h t cable above 1000v to 11kv super tension or s t cable above 11kv to 33kv extra high voltage or e h t cable above 33kv to 66kv extra super voltage or e s t cable above 66kv related. Automotive applications signal wiring in electrical and electronic devices flexible power cables etc.
