The FPQ series composite pin insulators have good hydrophobicity, aging resistance, resistance to leakage current tracking, and resistance to electrical erosion, along with being lightweight and easy to install. They also possess high bending strength, impact resistance, shock resistance, and anti-brittle fracture performance, making them highly effective in power station facilities. The installation dimensions at the top and bottom of the insulator correspond to the dimensions of the respective porcelain pillars and can be used interchangeably.
The FPQ series composite pin insulators produced and sold by our company use fittings made of special steel. The ends of the fittings adopt a labyrinth design principle, providing multi-layer protection and good sealing performance, which solves the most critical issue of "interface electrical breakdown" for insulators.

The pin insulator is a critical component in the electrical distribution system, designed to support conductors on poles while preventing current flow to the ground. Made from weather-resistant ceramic or composite materials, pin insulators ensure high electrical insulation and mechanical reliability. They are particularly suitable for medium-voltage overhead lines and are commonly installed on cross-arms or pole tops.
Engineered for long service life, each pin insulator undergoes rigorous testing to withstand mechanical loads and electrical stress. Their design includes a grooved head for secure conductor placement and a strong metal pin for safe and stable mounting. The hydrophobic surface of the pin insulator prevents water film formation, reducing flashover risks during wet conditions.
Pin insulators are essential for maintaining the integrity of power lines across diverse geographic and climatic environments. Their compact and cost-effective design makes them a popular choice for utility companies seeking reliable insulation solutions. Trust pin insulators to deliver optimal performance in every segment of your power distribution system.
