RHH Cables

RHH cables are very similar to RHW cables, with two major differences. While only one letter is different in the respective codes, keep in mind what we talked about above. We already covered that the “R” stands for a rubber insulation and the “HH” details the heat resistance.

R: Rubber insulation

HH: Heat resistant up to 90 degrees Celsius

This means that while RHH cables can withstand a higher temperature than RHW cables, they do not possess the water resistance trait that RHW cables boast. This doesn’t mean one cable is better than the other or vice-versa; it simply means that each cable is specifically designed to work in different locations.

RHW-2 wires are suitable for direct burial in both wet or dry locations. Along with RHH cables, they hold a 600 voltage rating. Both cables can be found in general wiring applications, lighting and power systems – depending on the location and surrounding environments.
