Porcelain double suspension insulator string
Porcelain double suspension insulator string is used at medium voltage overhead lines for mounting and supporting the cables with the suitable cross section. Porcelain suspension insulator consists of mandrel, shed cover, end attachments, grading ring and other components.
There are three basic styles of porcelain unipart suspension insulator shells: "sombrero", which is flat, with multiple ridges or "skirts" on the under-side which increase the leakage distance; fog or "bell", in which the disk is curved into a bell or nearly hemispheric shape, the indent being to keep the ridgeless underside from being wetted as easily; and aero(dynamic) style, a wide flat disc (also with no ridges) which presents little cross-section and so is least affected by high winds.

Porcelain suspension Insulator definition:
Porcelain disc suspension Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The term Porcelain suspension insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. They support the weight of the suspended wires without allowing the current to flow through the tower to ground.
