　　Application and characteristics of glass insulators:

　　Classification of insulators

　　Insulators can be divided into high voltage insulators and low voltage insulators according to their operating voltage.

　　Insulators can be divided into ceramic insulators, glass insulators, and organic material (epoxy resin cast) insulators according to their manufacturing materials. Insulators can be divided into indoor insulators and outdoor insulators according to their installation locations.

　　Insulators can be divided into 11 subcategories and 48 series according to their structure and purpose. The main use of insulators

　　1) High voltage line insulators

　　① High voltage line rigid insulators: including needle type porcelain insulators, porcelain cross arm insulators, and butterfly type porcelain insulators. High voltage line porcelain cross arm insulators can be divided into four types according to their structural forms: all ceramic, adhesive, single arm, and V-shaped; According to the installation form, it can be divided into two types: upright and horizontal; According to the 50% full wave impulse flashover voltage, it can be divided into levels such as 185kV, 21OkV, 280kV, 380kV, 450kV, and 610kV. Used for high-voltage overhead transmission and distribution lines, it can replace pin and suspension insulators and eliminate the need for high pole porcelain supports.

　　High voltage line butterfly porcelain insulators are divided into two levels according to rated voltage: 6kV and 1OkV.

　　Used for insulation and fixing wires on overhead transmission and distribution line terminals, tension and corner poles. It is also widely used in conjunction with suspension insulators for power lines, as a component in line fittings, simplifying the structure of fittings.

　　② High voltage line suspension insulators: including disc-shaped suspension porcelain insulators, disc-shaped suspension glass insulators, porcelain rod insulators, and ground wire insulators.

　　High voltage line disc-shaped suspension porcelain insulators are divided into two types: ordinary type and pollution resistant type. Used for high voltage and ultra-high voltage transmission lines, to suspend or tension wires and insulate them from tower poles. Suspension insulators have high mechanical and electrical strength, and can be applied to various voltage levels and strength requirements through different string combinations, making them the most widely used. The regular type is suitable for& divide; General industrial area. Compared with ordinary insulators, pollution resistant insulators have a larger creepage distance and a shape that is easy to clean in wind and rain, making them suitable for coastal areas, metallurgical powder, chemical pollution, and areas with severe industrial pollution. When pollution resistant insulators are used in the above-mentioned areas, they can reduce the size of the tower and have significant economic value.
