YO has various meanings in the Electrical category. Discover the full forms, definitions, and usage contexts of YO in Electrical.
YO refers to a type of rubber-insulated, single-core electrical cable commonly used in light-duty installations and older electrical systems. The “Y” typically indicates rubber insulation, while the “O” denotes a single-core (monoconductor) structure. These cables are known for their flexibility and resistance to mechanical stress, making them suitable for portable tools, temporary power supply lines, or environments where cable movement is frequent. Though modern alternatives like PVC or XLPE-insulated cables are more common today, YO cables still see use in specific legacy systems or controlled environments.
In terms of electrical properties, YO cables typically operate within low to medium voltage ranges and are designed to withstand moderate thermal and mechanical demands. Their rubber insulation provides decent resistance against moisture, abrasion, and oil, but may degrade faster over time compared to synthetic insulators. For maintenance and retrofitting in older buildings or machinery, recognizing YO cables can be important for proper compatibility and safety evaluations.
