Galvanized Steel Pin Insulator, 33 KV Nominal Voltage, 245 mm Height

A pin insulator is a high-voltage insulating component used in overhead power distribution systems to support and electrically isolate conductors from grounded utility poles. Typically mounted on crossarms or poles via a steel or polymer pin, it provides mechanical support while preventing current leakage under varying environmental and electrical stress conditions. Pin insulators are widely deployed in medium-voltage networks due to their simplicity, durability, and cost efficiency.

Engineered from high-dielectric materials such as porcelain, glass, or polymer composites, pin insulators are designed to withstand electrical, mechanical, and environmental loads including wind, pollution, and temperature fluctuations.

Key Features:

• High dielectric strength for reliable electrical insulation
• Robust mechanical load-bearing capacity for conductor support
• Weather-resistant design suitable for harsh outdoor conditions
• Available in porcelain, glass, and polymer material variants
• Anti-tracking and erosion-resistant surface properties
• Compatible with standard pin-type mounting hardware
• Low maintenance with long operational service life
• Suitable for medium-voltage overhead distribution networks
