What does RW stand for in electrical terminology?

In electrical terminology, RW specifically refers to "Moisture Resistant Rubber compound." This designation indicates that the wire insulation is made from a rubber compound specifically formulated to resist moisture, which is crucial for ensuring safety and longevity in various applications where the wire may be exposed to damp or wet conditions. This moisture resistance helps prevent short circuits and degradation of the wire over time, making it suitable for outdoor or industrial use where exposure to moisture is a concern.

The other options, while they may sound plausible, do not accurately capture the specific meaning associated with RW in the context of electrical wiring. Rubber Wrapped, Regular Wire, and Resistant Wire might describe characteristics of different types of cables or wires, but they do not convey the important aspect of moisture resistance that RW represents, which is a critical factor in electrical applications.
