Introduction:
This is a modern Pin Composite Insulator, a key component in 24kV overhead electrical distribution systems. This 24kV Pin Insulator represents a significant technological advancement over traditional porcelain or glass insulators. It is engineered using a polymer material (like silicone rubber) reinforced with a fiberglass rod, resulting in a product that is lighter, stronger, and more resilient to environmental challenges. Its primary function is to mechanically support and electrically isolate live medium-voltage conductors from the grounded utility pole structure.

Order Information: | ||||||||||
Parameter Specifications Explanation:
Rated Voltage: 24 kV (This indicates its designed operational voltage for medium-voltage distribution lines.)
Mechanical Strength (Failing Load): 10 kN (Approximately 1,000 kgf. This signifies its ability to withstand significant mechanical forces, such as conductor weight, wind, and ice loading.)
Number of Sheds: 7 (The disc-like protrusions that increase the surface leakage path.)
Creepage Distance: 680 mm (The total length along polymer pin insulator's surface between the live and grounded metal end-fittings. This long path is crucial for preventing electrical flashover, especially in polluted or wet conditions.)
Color: Grey (A common color for composite insulators, often associated with specific polymer formulations like cycloaliphatic epoxy or filled silicone rubber.)
Characteristics & Advantages:
Lightweight: Compared to equivalent porcelain insulators, composite insulators are significantly lighter. This simplifies transportation, handling, and installation, reducing labor costs and the risk of breakage during assembly.
High Mechanical Strength: The core is typically a rod of high-strength fiberglass reinforced with resin. This gives it an excellent strength-to-weight ratio and a high specified mechanical failing load (10kN in this case).
Excellent Pollution and Moisture Performance: The silicone rubber housing (or similar polymer) is hydrophobic. This means it repels water, preventing the formation of a continuous conductive film on its surface. Water beads up and rolls off, often carrying away surface contamination—a property known as self-cleaning. The specific design with seven sheds and a long 680mm creepage distance is optimized to manage leakage currents in harsh environments.
Vandalism and Impact Resistance: The polymer and fiberglass construction is much more resistant to damage from gunshots or impacts than brittle porcelain or glass, leading to improved reliability and reduced maintenance.
Long Service Life: These insulators are highly resistant to the primary causes of insulator aging: ultraviolet (UV) radiation, tracking, and erosion. They are designed for a long operational life with minimal degradation in performance.
Applications:
This 24kV Silicone Pin Insulator is primarily designed for use in overhead power distribution networks.
It is mounted onto a steel pin that is bolted to the cross-arm of a wooden, concrete, or steel utility pole.
The live conductor (wire) is secured in the groove of the metallic cap at the top.
The threaded metal stud at the bottom is attached to the grounded pin on the pole, creating the necessary electrical isolation.
Its robust parameters make it ideal for medium-voltage applications (e.g., 11kV, 24kV systems) in areas with challenging conditions, including:
Coastal regions with salt spray pollution.
Industrial areas with airborne contaminants.
Regions with high humidity, fog, or frequent rain.
