Product Introduction:
This is an 11kV, 10kN Grey Silicone Rubber Pin Insulator featuring a sophisticated five-shed design. As a fundamental component in medium-voltage overhead power distribution networks, its primary function is to electrically insulate live conductors from the supporting utility poles while providing robust mechanical support. The distinctive & big-small alternating shed profile is engineered to achieve a substantial creepage distance of 450mm, making it a reliable choice for demanding environmental conditions.

Key Features and Design Advantages:
Optimized Electrical Performance (11kV, 450mm Creepage): The rated voltage of 11kV qualifies it for standard distribution lines. The 450mm creepage distance is a critical feature, providing a long leakage path along the insulator's surface. This effectively prevents flashovers—unwanted electrical discharges—caused by pollution, dust, salt fog, or moisture.
Big-Small Shed Design: The five-shed configuration with alternating diameters is not merely aesthetic. This design maximizes the surface area and creepage distance without increasing the insulator's overall height. It also promotes efficient water shedding during rain, disrupting continuous water films that can lead to short circuits.
Robust Mechanical Strength (10kN): With a mechanical strength rating of 10 kilonewtons (approximately 1 metric ton), this composite insulator can reliably support the weight of the conductors, along with additional loads from ice accumulation and wind pressure, ensuring long-term structural integrity.
Durable Material (Typically Porcelain or Toughened Glass): Traditionally manufactured from high-strength porcelain or toughened glass, the grey insulating body offers excellent dielectric properties, high compression strength, and resistance to weathering and UV degradation. The material is non-porous, preventing water absorption.
Corrosion-Resistant Fittings: The insulator is equipped with galvanized steel fittings. The top consists of a pin terminal with a groove for securely tying the conductor, and the base is a threaded shank for screwing directly into a pole-mounted cross-arm or bracket.
Production Process (Traditional Method):
The manufacturing of this pin polymer insulator typically follows a well-established process for ceramic/porcelain units:
Raw Material Preparation: A mixture of high-purity clay, feldspar, and quartz is blended to create a homogenous ceramic body.
Forming/Shaping: The mixture is shaped using a high-pressure hydrostatic pressing machine in a steel mold. This process forms the precise grey body with its five-shed profile in a single step.
Glazing (Optional): The pressed body may be coated with a glossy or semi-matte glaze to further enhance its hydrophobic properties and make the surface smoother, which aids in the self-cleaning process during rain.
High-Temperature Firing: The shaped insulators are fired in a kiln at temperatures exceeding 1200°C. This vitrification process sinters the ceramic particles, making the body incredibly strong, dense, and impervious to water.
Metal Fitting Assembly: The galvanized steel pin and socket are securely cemented to the ceramic body using a high-strength Portland cement or a similar compound. This assembly is then cured to achieve a permanent, solid bond.
Rigorous Quality Control: Each insulator undergoes stringent tests, including:
Electrical Test: High-voltage power frequency tests to verify the 11kV rating.
Mechanical Test: Sample units are tested to destruction to ensure they meet or exceed the 10kN load rating.
Porosity Test: To confirm the impermeability of the ceramic material.
Application Scenarios:
This 11kV pin insulator is widely deployed in:
Overhead Distribution Lines (11kV Systems): Its primary application is on utility poles in urban, suburban, and rural areas to support and insulate primary distribution lines.
Pole-Mounted Transformers: It is used to insulate the incoming high-voltage lines connected to distribution transformers.
Branch Line Support: Ideal for providing support at points where lines branch off the main feeder.
