Insulator is a special insulation controls, can play an important role in the overhead transmission lines.Insulator used for the early years of poles, and slowly developed in the high-pressure end of the wire connecting the tower were a lot of disk-shaped insulator, which is to increase the creepage distance, usually made of glass or ceramic, called Insulator.Insulator should not be due to various mechanical and electrical stress changes caused by environmental and electrical load conditions occur and fail, otherwise Insulator would not have a significant effect, it will damage the use and operation of the entire line of life.

Insulator according to a different installation, and can be divided suspension strut Insulator Insulator; used according to different insulation materials can be divided into Insulator porcelain, glass and Composite Insulator Insulator (also known as synthesis Insulator); used according to different voltage levels, divided into insulator insulator low pressure and high pressure; according to different environmental conditions of use, the dirty areas derived using stain insulator; used according to different types of voltage, current derived insulator; insulator there are a variety of special purpose, such as insulation cross arm, Insulator semiconductor enamel with tensioning Insulator and distribution, and cabling spool Insulator Insulator like.Further, according to the different possibilities insulation breakdown, i.e. type A can be divided into non-punch-through type and B type to breakdown Insulator Insulator two type.
Insulator suspension widely used in high voltage overhead transmission lines and hair, soft substation bus insulation and mechanical fixing.Insulator in suspension, the suspension can be divided into disk-shaped and Rod Insulator Insulator.Insulator pin type transmission line is one of the most widely used Insulator.Rod Insulator has been widely adopted in Germany and other countries.
Insulator insulation and mechanical fixing strut mainly for bus bars and electrical equipment of power plants and substations.Additionally, often as part of the strut Insulator disconnectors and circuit breakers and other electrical equipment.In Insulator pillar, the pillar can be divided into pin and rod post Insulator Insulator.Insulator strut needle used for low-voltage distribution line and a communication line, used for high-pressure rod post Insulator substation.
Insulator Ceramic Insulator insulating member made of a ceramic electrician.Electrician ceramic composed of quartz, feldspar and clay made from baking ingredients.Insulator ceramic surface of porcelain enamel cover generally, to improve its mechanical strength, water infiltration, increased surface smoothness.In all kinds of Insulator, the most widely used porcelain Insulator.
Insulator Insulator glass insulator made of steel after treatment is made of glass.In which the surface compressive prestressing state, such as electrical breakdown and cracking, the glass itself Insulator break into small pieces, commonly known as “SELF”.This feature makes the glass without Insulator “zero value” in the operation of the detection.
Also known as synthetic Insulator Composite Insulator.Insulator insulation member made of glass fiber resin mandrel (or core tube) and the sheath and sheds organic material composed of.It features small size, light weight, high tensile strength, excellent anti-contamination performance flashover.But resistance to aging as good as porcelain and glass Insulator.Composite Insulator comprising: Rod Insulator, insulating cross arm, and a hollow strut Insulator Insulator (i.e., composite bushing).Alternatively the composite bushing of electrical equipment used in a variety of porcelain, such as transformers, surge arresters, circuit breakers, condenser bushing and cable terminals.Compared with porcelain, which in addition to having high mechanical strength, light weight, small size tolerances advantages, but also to avoid damage caused by decrepitation.
Insulator low pressure and high pressure low pressure Insulator Insulator Insulator means for low-voltage distribution lines and communication lines.It refers to high pressure Insulator Insulator for a high voltage, EHV transmission lines and substations.In order to meet the needs of different voltage levels, typically with a different number of the same type Single (member) composed of insulating pillars Insulator Insulator string or section.
Fog Insulator primarily measures to increase or increase Insulator sheds or umbrella ribs to increase Insulator creepage distance, in order to improve the electric strength at Insulator filthy state.Also take the structural shape change shed to reduce the amount of the surface nature of the contamination, to improve the antifouling performance of the flash of Insulator.Fog Insulator creepage distance is generally better than ordinary Insulator increased by 20% to 30%, and even more.World Power flashover prone areas using customary stain Insulator double umbrella-shaped structure, such Insulator strong self-cleaning ability, easy manual cleaning.
Insulator refers mainly used in DC HVDC disk-Insulator.Usually sacrificial DC Insulator Insulator Fog type than AC electric longer creep distance, the insulation member has a higher volume resistivity (50 deg.] C is not less than 10Ω · m), which is connected fittings should install anti-electrolytic corrosion electrodes (such as zinc sleeve, zinc ring).
Insulator type A and B type InsulatorA i.e. non-punch-through type Insulator, which is not dry dry flashover distance breakdown 3 times (casting resins) or 2 times the distance (Other Materials): breakdown of type B to type Insulator, which distance is less than the breakdown 1/3 dry (casting resins) or 1/2 (other materials) flashover distance.Insulator dry flashover distance refers to the shortest distance via the insulating member along the outer surface of the air; the shortest distance from a breakdown in the insulating material of the insulating member via.
