What are medium-voltage insulated conductors categorized by?

Medium-voltage insulated conductors are categorized primarily by their shield type. This categorization is critical because the shield's function is to contain the electric field within the conductor and to provide a path to ground for any fault currents, which is essential for safety and performance in electrical systems. Different types of shields can affect the conductor's ability to handle voltage, reduce electromagnetic interference, and ensure adequate insulation resistance.

Understanding the shield type can influence not just installation practices, but also how the conductor performs under varying environmental conditions. This is particularly relevant in medium-voltage applications, where insulation quality and effectiveness are paramount for reliable operation over time. The other factors mentioned, such as connector type, conductor size, and insulation color, while important in certain contexts, do not serve as the primary basis for categorizing medium-voltage insulated conductors.
