Suspension Insulator String
|
Consists of multiple
porcelain or glass insulator
discs connected by steel
pins and shackles. The discs
have a smooth or ribbed
surface to enhance
creepage distance. They are
available in various sizes
and mechanical strength
ratings.
|
Mainly used in high - voltage transmission lines (ranging from 35 kV to 1000 kV and above). Suitable for long - span lines and areas with high electrical stress, capable of withstanding large tensile forces and providing effective insulation against electrical discharges. |
|
Post Insulator
|
Has a solid, cylindrical body made of porcelain, epoxy resin, or composite materials. It can be either a single - piece or multi - piece structure with flanges or threaded ends for easy installation. | Widely applied in substations, switchgear, and other electrical equipment. Used to support and insulate conductors, busbars, and other electrical components, ensuring electrical isolation and mechanical stability. |
|
Pin Insulator
|
Features a pin - shaped structure at the top for mounting conductors. The body is typically made of porcelain and may have a single or multiple petticoat design to increase the insulation distance. | Commonly used in low - voltage distribution lines, usually in the range of 1 kV to 35 kV. Ideal for pole - mounted installations where it provides basic insulation for overhead conductors. |
| Strain Insulator | Usually has a double - cone or dumb - bell shape. Made of porcelain or composite materials, it is equipped with strong metal end - fittings for connection to wires or cables. |
Applied in overhead lines at dead - end, corner, and tension points. Designed to withstand high mechanical tension forces while maintaining electrical insulation, especially in areas with significant wind or other environmental stress.
|
| Composite Insulator | Comprises a fiberglass core wrapped with silicone rubber sheds. The sheds are designed in various shapes, such as conical or umbrella - like, to improve hydrophobicity and anti - pollution performance. | Suitable for all voltage levels, but especially popular in areas with high pollution or harsh environmental conditions. It offers advantages like lightweight, high mechanical strength, and excellent resistance to electrical tracking. |
| Tension Insulator | Constructed with a high - strength ceramic or composite body and metal inserts for connection. It has a compact design to fit in tight spaces within the electrical system. | Used in guy wire assemblies of transmission towers and other structures. Ensures that the guy wires are electrically insulated while withstanding the tension forces exerted on them. |
