Introduction:
Its 11-shed grey silicone rubber design with 1100mm creepage distance and specific protected features offers a significant advantage in flashover prevention.
Specifications:
Product Description: Composite Pin Insulator, is also named Polymer Pin Insulator, Silicone Rubber Pin Insulator.
Product Type: FPW-33-10--1100mm-M22-140mm
Height(mm): 385± 10
Min Dry Arcing Distance(mm): 330
Min Creepage Distance(mm): 1100
Diameter of the rod(mm): 38
Number of sheds: 11
Sheds of diameter(mm): 140/110
Screw diameter/ Screw length(mm): M22/140
Rated Bending Load(kN): 10
Rated Voltage(kV): 33
Lightning Impulse Withstand Voltage(kV): 250
Power Frequency Withstand Voltage(kV): 105
Key Specifications & Features:
Voltage Class:
This high voltage composite insulator is designed for medium-voltage 33kV (33,000 Volts) power distribution systems, suitable for primary distribution lines and substation applications.
Mechanical Strength:
Rated with 10kN (10 kilo-Newtons) cantilever strength, providing robust mechanical performance to withstand conductor loads, wind forces, and ice accumulation.
Composite Material:
This 33kV Pin Insulator constructed with grey High-Temperature Vulcanized (HTV) Silicone Rubber. This material offers:
Superior Hydrophobicity:Repels water, minimizing leakage current.
UV Resistance:Withstands prolonged sunlight exposure without degradation.
Pollution & Chemical Resistance:Performs reliably in industrial and coastal environments.
Lightweight:Significantly lighter than porcelain/glass equivalents.
Shed Design:
Features an 11-shed profile. This optimized shed geometry:
Maximizes the creepage distance (1100mm) for enhanced pollution performance.
Improves self-cleaning capability during rain.
Prevents flashover by effectively interrupting the path of surface leakage currents.
The grey color provides visual contrast and maintains aesthetic appeal.
Protected (Anti-Flashover) Design:
Engineered as a Protected Design specifically to:
Suppress Dry Band Arcing:Prevents the formation of damaging arcs on the insulator surface under polluted/wet conditions.
Increase Pollution Withstand Voltage (PSDD):Allows safe operation in areas with heavy industrial pollution, road salt spray, or desert dust (e.g., achieving Class IV / Heavy pollution per IEC 60815).
Enhance Reliability:Significantly reduces the risk of pollution-induced flashovers, minimizing outages
Creepage Distance:
A substantial 1100mm creepage path ensures exceptional performance in contaminated environments, exceeding standard requirements for 33kV systems in severe service areas.
Core:
Utilizes a high-strength fiberglass reinforced polymer (FRP) rod core. This core:
Provides excellent tensile and cantilever strength.
Is non-brittle and shatterproof.
Resists torsional stresses.
Features excellent dielectric properties.
End Fittings:
Equipped with corrosion-resistant hot-dip galvanized steel or malleable iron fittings compatible with standard pin and crossarm configurations. Crimped or threaded connections ensure mechanical integrity.
Applications:
Ideal for:
Overhead distribution lines (33kV) in coastal, industrial, desert, or high-pollution zones.
Upgrading ageing porcelain/glass insulators for improved reliability.
Areas requiring lightweight solutions for easier handling and installation.
Critical circuits where minimizing pollution flashovers is essential.
Advantages over Traditional Insulators:
Lightweight: Easier/cheaper handling & installation.
Vandalism & Impact Resistant: Won't shatter.
Maintenance-Free:No washing or greasing required.
Long Service Life:Resists weathering and degradation.
Superior Pollution Performance:Proven performance in harsh conditions due to silicone rubber hydrophobicity and protected design.
Seismic Resistance:Flexible FRP core performs well in earthquakes.
