Key Selling Points
- Direct Mounting Design: No string required, fastens directly to crossarm pins for 6kV/10kV distribution lines, reducing installation complexity and cost
- High-Density Porcelain Build: High-temperature fired glaze (White/Brown) delivers superior dielectric strength, moisture resistance and long-term durability
- Optimized Mechanical Stability: Bending failure load up to 14kN, wind/ice load resistant, stable support for straight-line and light angle conductor runs
- Versatile Mounting Configurations: T/M series variants with M16 thread, varied pin lengths (h1/h2) to suit standard/heavy-duty crossarm designs
Product Description
Economical & Reliable Insulation for 6kV-10kV Distribution Networks The P/PQ Series Pin Type Porcelain Insulator is a core component for medium and low-voltage overhead power distribution systems. Engineered for voltage ratings up to 10kV, these insulators mount directly onto the pole’s crossarm pins, offering a compact, cost-effective solution for rural electrification, urban distribution grid upgrades and industrial power line projects. Core Engineering Advantages Crafted from dense, non-porous porcelain fired at high temperatures, our pin-type insulators feature a smooth, glossy glaze surface that enables self-cleaning via rain/wind, maintaining consistent insulation performance even in humid or lightly polluted environments. P Series (Standard Type): Balanced performance for general distribution lines, with creepage distances from 150mm to 560mm PQ Series (Anti-Pollution Type): Enhanced creepage distance (255mm-370mm) for coastal salt-fog or industrial dust zones, reducing flashover risks T Series (Standard Shank): Compact pin length for standard crossarms, ideal for routine construction M Series (Extended Shank): Longer pin length for thick/heavy-duty crossarms, suitable for mountainous or retrofitted lines
