Product Description

Composite Pin Insulators are essential components used in high voltage overhead power distribution lines. These insulators are constructed with a fiberglass-reinforced plastic (FRP) core, silicone rubber housing, and metallic fittings, ensuring superior performance and durability.

Key Features

  • Robust Construction: The insulator features a strong FRP core that provides high mechanical strength and excellent electrical insulation properties.
  • Durable Silicone Rubber Housing: The silicone rubber housing offers exceptional resistance to weathering, UV radiation, and pollution, ensuring long-term reliability in harsh environments.
  • Secure Metallic Fittings: The insulator is equipped with metallic fittings on both ends. The bottom fitting, known as the pin, includes a screw for secure attachment to the cross-arm. The top fitting, or header, features a groove designed to hold conductors firmly in place.

Conditions of Use

  • Temperature Range: Suitable for ambient air temperatures from -40°C to +40°C.
  • Altitude: Effective up to 1,000 meters above sea level. For altitudes exceeding 1,000 meters, adjustments are required.
  • Frequency: Designed for AC power supply frequencies up to 100Hz.
  • Mechanical Load: Capable of handling mechanical loads up to the rated value.

Product Advantages

  • 1. Compact and Lightweight: The compact and lightweight nature of Composite Pin Insulators simplifies transportation and installation processes. Their reduced size and weight mean fewer resources are needed for handling and placement, which in turn lowers the overall labor and logistical costs associated with their deployment.
  • 2. High Performance: These insulators exhibit exceptional mechanical strength, making them highly effective in withstanding the stresses encountered in power line infrastructure. Their superior reliability ensures consistent performance, reducing the likelihood of power outages and the need for frequent replacements.
  • 3. Hydrophobic and Contaminant-Resistant: Composite Pin Insulators’ hydrophobic properties prevent the absorption of water, which is key to avoiding the conductive path that could lead to electrical leakage. Their resistance to contamination further protects against environmental factors that could otherwise impair their insulating capabilities, thereby ensuring that maintenance needs are kept to a minimum.
  • 4. Long-Term Durability: With excellent aging resistance, Composite Pin Insulators maintain their insulating properties over time without significant degradation. Their ability to resist leakage tracking means they can continue to provide reliable insulation even in damp or humid conditions, ensuring a long service life with sustained performance.
