As a professional pin insulator manufacturer, we produce most of electrical insulators. Electrical insulator for sale is necessary. We want to know how to sale electrical insulator. I have suggestion for you.

Firstly, must know what the electrical insulator is?
Electrical Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves.

Secondly, what do the properties of electrical insulator have?
◆Application: transmission and distribution line, electrical tower or substation.
◆Voltage range: 10KV, 11KV, 22KV, 33KV, 35KV, 66KV, 69KV, 110KV, 220KV, 230KV, 330KV, 400KV, 500KV and so on. Such as porcelain pin type insulator voltage have 11KV, 22KV, 33KV, 15kV, 25kV, 35KV, 36kV etc.
◆Mechanical strength: 2KN, 4KN, 6KN, 8KN, 10KN, 12.5KN, 16KN, 70KN, 80KN, 100KN, 120KN, 210KN, 300KN, 530KN. Such as mechanical strength of porcelain pin insulator has only 2KN, 4KN, 6KN, 8KN, 10KN, 12.5KN, 16KN.
◆Materials: porcelain, glass, polymer etc.

The last, you must know the price of all type electrical insulators. For example, you must know how much a 33kV 2kN composite pin insulator is.
