What does RHW stand for in conductor/wire and insulation?

RHW stands for Moisture and heat resistant rubber, which is significant in the context of electrical conductors and wiring. This designation indicates that the insulation used on the wire is designed to withstand both moisture and elevated temperatures, making it suitable for use in environments where these conditions are present. This type of insulation is particularly important for electrical systems that may be exposed to damp conditions or that operate at high temperatures, as it ensures safety and longevity of the wiring.

Moisture resistance helps to prevent corrosion and other damage to the wire's conductor, while heat resistance maintains the integrity of the insulation, even when the wire is carrying high currents. This balance of properties makes RHW wire ideal for a variety of applications, including residential, commercial, and industrial settings, where wiring may be exposed to challenging environmental conditions.
