Suspension insulator according to the umbrella classification

Ordinary Suspension Insulators

The umbrella insulators is to use one of the oldest suspension insulator, he is characterized by structural shapes simple, low cost, suitable for cleaning areas choose to use. They are typically used in the exchange of transmission lines.

Bell-type suspension porcelain insulator

Under the umbrella insulator has a long umbrella ribs, the product can achieve greater creepage distances cavity under the umbrella difficult to damp, has high withstand voltage filthy, more suitable for coastal, foggy and wet and saline areas AC and DC transmission lines to use.

Double umbrella, three umbrella Suspension Insulators

Both the shape of the product due under the umbrella of a smooth shape without edges and into an open, so its good self-cleaning properties storm, natural contamination rate, coupled with the large creepage distance, the product has a good level of pressure sewage , used in dusty environments to better play to the superiority of mushroom structures. This umbrella insulator is called "aerodynamic type", they adapt to a variety of operating conditions, especially heavy contamination, AC and DC transmission lines and the high altitude desert dry areas.

Straw hat Suspension Insulators

The products are particularly large disk diameter umbrella, umbrella smooth without edge, streamlined structure, good self-cleaning, dirt accumulated small amount, it is characterized by the use of interspersed AC DC line insulator overhanging the upper and middle strings, King of the disc diameter structure can restrain the ice slide and guano lines caused pollution flashover occurs.
