Medium Voltage Pin Insulators ANSI 55-5

Classification of Porcelain Pin Insulators

Porcelain pin insulators are essential components in the transmission lines industry. These insulators are classified by voltage level and pin length:

• Voltage Level:
  • High-Voltage Pin Insulators: Designed for high-voltage applications.
  • Low-Voltage Pin Insulators: Suited for low-voltage use.
• Pin Length:
  • Long Leg Pin Insulators: Ideal for use on wooden crossarms.
  • Short Leg Pin Insulators: Fit for iron crossarms application.
