Best Price 70kn 550mmLong Rod Suspension Porcelain Insulator Lp705390

1. High mechanical strength and good bending resistance
Structural design: Using solid or high-strength materials (such as porcelain or composite materials) as a whole, without internal splicing or metal components, to avoid stress concentration points.
Wind resistance and vibration: suitable for large-span and high tension scenarios (such as high-voltage lines and large-span towers), able to withstand wire tension and mechanical loads in harsh weather conditions.
2. Excellent anti pollution flash performance
Umbrella skirt design: The umbrella skirt has a simple structure and a smooth surface, reducing the accumulation of dirt (dust, salt spray, etc.) and lowering the risk of pollution flash.
Self cleaning ability: Rainwater can easily wash away surface dirt, maintain insulation performance, suitable for high pollution areas (industrial areas, coastal areas).
3. Reliable electrical insulation performance
Long creepage distance: By increasing the length of insulators or the number of umbrella skirts, the surface discharge voltage can be increased, suitable for high voltage levels (such as 220kV and above).
No internal breakdown risk: The solid structure avoids internal air gap discharge problems and has high long-term stability during operation.
4. Low maintenance cost and long lifespan
Aging resistance: Ceramic or silicone rubber materials are resistant to ultraviolet radiation, corrosion, and have strong environmental adaptability (high temperature, low temperature, humidity).
Maintenance free: No complex components, not easily damaged, reducing inspection and replacement frequency.
5. Easy to install and lightweight
Modular design: Long single section length reduces installation quantity and simplifies construction.
Lightweight: Composite material pull rod insulators are lighter than traditional ceramic insulators, reducing tower loads.
6. Strong seismic and impact resistance
Flexible structure: Some designs have a certain degree of elasticity, which can buffer earthquakes or external impacts, suitable for earthquake prone areas.
Creepage distance 660mm vs 550mm

Typical application scenarios
High voltage/ultra-high voltage transmission lines
Large span tower, substation
