Porcelain Insulator

Suspension Porcelain Insulator

Suspension porcelain insulator is used for insulated conductor and fixed conductor of overhead line. Normally composed insulator string is used for different voltage classes. Creepage distance is increased by increasing of insulator quantity to improve pollution flashover performance....

Post Porcelain Insulator

Pillar type insulator is mainly used for outdoor purpose. Outdoor pillar type is divided into pillar rod type insulator, pillar needle type insulator and piled-cone insulator. Outdoor rod type insulator has solid round porcelain pillar including umbrella. Umbrella is used to keep some surface of insulator dry in rainy day and improve leak...

Rod Type Porcelain Insulator

Long rod suspension type insulator has non-breakdown structure with balloon fitted outside. In recent years, this kind of insulator is applied of non-breakdown structure, deep creepage skirt and middle & big creepage distance structure. Normally rod type insulator is applied of lead antimony alloy to fix fitting. This kind of fixer is no...

Pin Porcelain Insulator

Needle type porcelain insulator consists of porcelain with umbrella, iron pin inserted to porcelain and iron cap above porcelain. It may bear bend loading directly. Needle type porcelain is simply manufactured and has low cost. It can be installed conveniently. It’s widely used in 6~10KV electric power circuit. But this kind of in...

Porcelain Cross-Arm

Porcelain pole arm is a kind of cone or pillar type insulator used for overhead electric power circuit. Compared with hypothetical circuit of normal insulator, its strong points as following: Rotating structure is applied. When circuit is disconnected, tension unbalance of conductor may rotate porcelain pole arm to effectively relieve ex...

DC Porcelain Insulator

DC insulator has longer creepage distance than AC insulator. It has higher resistivity for insulation condition. There is big difference in design and manufacturing between DC insulator and AC insulator. Under effect of DC electric field fixed direction, ion inside insulation material moves, which changes the material and degra...

Glass Insulator

Suspension Type Glass Insulator

Glass insulator has bigger dielectric consonant than porcelain insulator. Minimum thickness may be achieved under the same mechanical strength and breakdown voltage compared with porcelain insulator, which may reduce dimension and weight of insulator. But pontaneous detonation rate of glass product is high. Fragments dropped ou...

Pin Glass Insulator

Needle type glass insulator belongs to line insulator. There is no principal difference in structure and respective scope of application compared with porcelain insulator....
