Composite insulator composite polymer insulator composite silicone insulators are a special type of insulation control that can play an important role in overhead transmission lines.

Composite insulators are also known as synthetic insulators, non-porcelain insulators, polymer insulators, rubber insulators, etc. The main structure is generally composed of a shed skirt, a FRP core rod and an end fitting. The shed skirt is generally made of organic synthetic materials, such as ethylene propylene rubber, high temperature vulcanized silicone rubber, etc.; FRP mandrels are generally made of glass fiber as a reinforcing material, and a oxidizing resin as a base material; The end fittings are generally carbon steel or carbon structural steel coated with hot zinc-aluminum.

 

Classification of Silicone Rubber Insulators silicone rubber insulator silicone composite insulators

Composite insulators can be divided into: line composite insulators and power stations, electrical composite insulators. It can also be divided into rod-shaped suspension composite insulators, pin-type composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof partial composite insulators, and so on.

 

Advantages of Composite Silicone Insulator

Small size, easy to maintain;

Light weight, easy to install;

High mechanical strength, not easy to break;

Excellent seismic performance and good stain resistance;

Fast production cycle and high quality stability.

End Fitting Structure

Composite insulators vary in their structure depending on the characteristics of use. In addition to meeting the tensile strength, meeting the requirements, and reliably connecting with the mandrel, the design of the metal tip also needs to meet the special requirements for application under high voltage. Composite insulators are generally made in the shape of a rod with a small capacitance. Therefore, the voltage distribution on the surface of the insulator is very uneven. Thus, in normal operation, the generated corona will be harmful, so it is necessary to use a pressure equalization measure. In addition, the synthetic insulating material cannot withstand an electric arc of several tens of kiloamperes. In the event of a short circuit fault, it will burn the umbrella near the wire and the tower, so arcing is required. At home and abroad, the method of adding a pressure equalizing ring is generally adopted to uniform the end electric field, weaken the corona, and lead to the fault arc.

 

The voltage equalizing ring of the composite insulator is a component of the composite insulator. Its function is to control the electric field strength inside the insulator, avoid internal partial discharge, reduce the local electric field strength of the external surface, especially the surface of the metal connecting part, and reduce the radio interference. Leading the power frequency arc to avoid burning the surface of the insulator and minimizing the local electric field strength near the end surface to improve its anti-smudge performance.

The silicone rubber insulation coating is made from special silicone rubber, high-performance material and other polymers by polymer blending technology. Its basic structural unit is silicon - oxygen chain while its side chain is connected by silicone with another organic radical group. Therefore, this structure makes the coating well combine the properties of both organic and inorganic compound. This product can used for the equipment and components which need protection of insulation, thermos conduction, fire retardant, dampness-proof, etc., such as bare wire, busbar, cable, high-power generator, dry-type reactor, dry-type transformer, switch cabinet and so on, it's quite suitable for the electrical equipment which operated in contaminated and humid environments.

Item Silicone Rubber Insulation Coating Heat Shrink Tube

Electrical Insulation Excellent electrical insulation. Breakdown Voltage is more than 25 kV/mm. Common performance.

Cover Effect Excellent adhesion.

The coating layer is intense, it could strongly stick to the equipment surface and could well resist to the corrosion caused by acid, alkali, salt and air. Common cover effect especially in the connection part.

Thermal Conductivity The coating has closely attached to the conductor and has good thermal conductivity could better release the heat of equipment. Its thermal conductivity is 0.2W/ (m. k), which is ten times then air. Relatively poor due to there is air gap between the tube and equipment.

Flame Retardant Hard to burn and has good fire retarding ability up to FV-0 Class. Easy to deform, crack and broke.

Application Favorable hardness makes its construction time is short. (less than one working day)

It can well fit and protect the surface of special shaped equipment or components and special connection position so that to make the conductors as one. Long construction time and need to disassemble the equipment.

It’s easy to crack and broken for the coating on the special shaped equipment or components and the connection or twist place.

Maintenance Easy to maintain and repair. The coating will not affect the dismounting of screw or bolt. Moreover, if recoating, the new coating can have integrated fuse with the old coating tightly. Although it’s also convenient to maintain and repair, but the connection place is easy to peel and broke.

Ageing Resistance Good hydrophobicity and resistance to ageing, dampness, ozone, radiation, UV, etc. make it free of maintenance and can serve for a long time. Its service life could be more than 20 years. Poor ageing resistance, its service time is about 5 years or even less especially in some bad environment the cracking and break phenomenon will happen.
