1.The meaning of RHH/RHW/USE wires

RHW

R: Rubber insulation

This rubber outer layer is very important when it comes to copper cables, especially when those cables are utilized in possible hazardous environments. Performance Wire and Cable`s RHW-2 wires are insulated by cross-linked polyethylene. Even though the [R" stands for rubber, it also incorporates other neoprene insulations that XLPE falls under.

H: Heat resistance of 75 degrees Celsius

Again, cables must be able to withstand the elements. You`ll occasionally see [HH" on some wires, which details the wire`s ability to resist heat up to 90 degrees Celsius. The insulation`s length and width help determine its heat resistance. The thinner the XPLE is, the less resistant it is to heat.

W: Water resistant

Depending on location, this factor could be the most important for your wire. The [W" label even suggests that the cables can be submerged in water if needed. Even if the wire has [R," which means it is acceptable to use in damp locations, it is wise to keep these wires away from water if the [W" isn`t present. Wires without this [W" label are susceptible to failure and erosion when exposed to water and other liquids.

So, RHW cable is a wire is insulated by rubber or something else (XLPE), can withstand heat up to 75 degrees Celsius, and is water resistant. That`s why RHW cables are regularly found underground in wet locations. However, the NEC lists RHW-2 as having the ability to withstand heats of up to 90 degrees Celsius, a fact that puts our RHW-2 wires ahead of the competitions` regular RHW wires.

2.The difference between RHH and RHW cable

? Pro-Line Type RHH or RHW-2 or USE-2 conductors are used with conduit as specified in the National Electrical Code1
? When used as Type USE-2, conductor is suitable for use as underground service entrance cable for direct burial at conductor temperatures not to exceed 90°C
? When used as RHH, conductor temperatures shall not exceed 90°C in dry locations
? When used as RHW-2 or USE-2, conductor temperatures shall not exceed 90°C in wet or dry locations
? Voltage rating for RHH or RHW-2 or USE-2 conductors is 600 volts
