Pin Insulator - Coating Type: As For Costmer

Pin insulators have specific features that make them suitable for various applications.

Key Specifications:

- Material: Pin insulators are made from non-conducting materials like porcelain, ceramic, silicon rubber, or polymer.
- Voltage Rating: They are used in power distribution systems up to 33 kV voltage levels, beyond which they become too bulky and uneconomical.
- Tensile Strength: Pin insulators have a minimum bending load of 5 kN for 11 kV and 10 kN for 33 kV.
- Creepage Distance: The minimum creepage distance for pin insulators is 320 mm for 11 kV and 900 mm for 33 kV.
- Dimensions: The length of the FRP rod is at least 165 mm for 11 kV and 300 mm for 33 kV, with a diameter of 20 mm for 11 kV and 24 mm for 33 kV.

Types of Pin Insulators:

- Porcelain Pin Insulators: Made from porcelain material, these insulators are durable and resistant to environmental factors.
- Polymer Pin Insulators: Made from composite materials, these insulators are lightweight and offer excellent electrical insulation properties.

Applications:

- Power Distribution: Pin insulators are used in power distribution systems for voltage levels up to 33 kV.
- Industrial Settings: They are used in industrial settings for electrical transmission and distribution.
- Sub-transmission and Distribution Lines: Pin insulators are suitable for use in sub-transmission and distribution lines .

Standards:

- IEC 61109: Pin insulators must conform to IEC 61109 standards for composite insulators for A.C. overhead lines above 1000 V.
- IS 2486: Pin insulators must also conform to IS 2486 standards for insulator fittings for overhead power lines
