Product Features:
Advanced Material Composition: This composite insulator is built with a high-strength Fiberglass-Reinforced Plastic (FRP) core for exceptional tensile strength, encased in a silicone rubber housing. This polymer material provides excellent hydrophobic (water-repellent) properties.
Optimized Shed Design: The 4-umbrella, large-and-small shed profile is engineered to enhance pollution performance. This design effectively disrupts the path of water during rain, promotes uniform wetting, and increases the surface resistance to leakage currents, thereby reducing the risk of flashover in contaminated conditions.
High Mechanical Strength: With a specified Mechanical Failing Load (MFL) rating of 70kN, this insulator is built to withstand significant mechanical tensions encountered in overhead power lines, including wind loads and conductor weight.
Superior Electrical Insulation: The 480mm creepage distance is a critical feature that provides a long leakage path along the insulator's surface, ensuring reliable insulation performance and high resistance to tracking and electrical flashover, even in polluted or humid environments.
Durability and Longevity: The silicone rubber housing offers excellent resistance to UV radiation, ozone, and temperature variations, ensuring a long service life with minimal maintenance compared to traditional porcelain insulators.
Lightweight and Vandal-Resistant: Composite insulators are significantly lighter than their porcelain counterparts, making them easier and safer to install. The polymer housing is also more resistant to impact damage.
Production Process:
The manufacturing of this polymer suspension insulator involves a precise, multi-stage process to ensure quality and performance:
Core Rod Fabrication: A high-strength Fiberglass-Reinforced Plastic (FRP) rod is produced via a pultrusion process. This creates a core with extremely high tensile strength, which is the primary load-bearing component.
Housing Molding: The FRP rod is then placed in an injection mold where high-temperature vulcanized (HTV) silicone rubber is injected under pressure to form the insulating housing. This single-step molding process integrally forms the four-umbrella sheds with the specific large-and-small profile, creating a seamless, waterproof bond with the core.
End Fitting Assembly: The metal end fittings (typically hot-dip galvanized steel), comprising a socket at the top and a ball at the bottom for easy connection, are crimped or swaged onto the ends of the FRP rod. This process creates a permanent, high-strength mechanical connection.
Quality Control and Testing: Each insulator undergoes rigorous testing to verify its specifications. This includes:
Mechanical Load Test: Sample units are tested to destruction to confirm the 70kN rating is exceeded.
Electrical Tests: Tests such as steep impulse voltage tests and power frequency withstand voltage tests are performed to ensure dielectric integrity.
Environmental Tests: Assessments for hydrophobicity transfer and recovery, as well as salt fog resistance, are conducted to validate performance in polluted conditions.
Application Scenarios:
This 11kV composite tension insulator is ideally suited for a wide range of applications:
Overhead Distribution Lines: Primarily used to suspend and electrically insulate conductors on 11kV overhead power lines from transmission towers or poles.
Polluted and Coastal Areas: Its excellent pollution performance makes it the preferred choice for industrial areas, coastal regions, and areas with high dust or salt contamination where frequent flashovers can occur with standard insulators.
Rural and Urban Networks: Its lightweight nature, durability, and reliability make it suitable for both expansive rural distribution networks and dense urban power grids.
Critical Infrastructure: Used in applications requiring high reliability and low maintenance, such as lines supplying hospitals, data centers, and industrial plants.
