A question we frequently get is what is the difference between SO cable and SOOW cable. They are the same basic cable but the SOOW cable has an oil resistant jacket and conductors whereas the SO cable only has an oil resistant jacket. The voltage and temperature ratings are the same for either version. The flexibility is the same also. Most manufacturers are only making the SOOW cable now as it covers most needs and building both types is not really cost effective.
