In modern power transmission systems, polymer insulators are widely used due to their lightweight design, high strength, and superior environmental resistance. However, not all polymer insulators are designed and manufactured the same way. Understanding these differences is crucial for ensuring long-term reliability and performance. Key Components of Polymer Insulators A typical polymer insulator consists of three primary components: The Importance of Mechanical Performance Polymer insulators are critical in mechanically supporting conductors while maintaining required clearance distances between phases. Their mechanical strength is crucial and typically falls into two main categories: Variability in End Fitting Designs While ANSI and IEC standards …
