RHRW is a building wire with tinned copper conductors, rubber insulation, and a saturated braid finish that is flame and moisture resistant for moist locations.
RHRW is a building wire constructed with tinned copper conductors, rubber insulation, and an outer saturated braid given a flame-resistant and moisture-resistant finish. The tinned conductors resist oxidation, the rubber provides the primary insulation, and the treated braid protects against moisture and flame, making the wire suitable for moist locations where these properties are needed.
The combination of moisture and flame resistance suits RHRW to environments where wire may be exposed to dampness, with the braid finish guarding the insulation and conductors. Building wire types are defined by their conductors, insulation, finish, and suitable locations, which guide appropriate use.
In commercial and industrial buildings, wires such as RHRW carry power in moist environments within their rating. Selecting wire with the correct construction and location suitability is part of applying it correctly.
Because its construction combines tinned conductors, rubber insulation, and a treated braid, RHRW guards both insulation and conductors against moisture and flame, suiting it to moist locations where these protective properties are needed for dependable power wiring.
At Windy City Wire, an understanding of building wire designations like RHRW reflects a focus on matching wire to its application and environment. Recognizing the conductors, insulation, and moisture and flame resistance helps customers select wire appropriate for their commercial and industrial systems.
