The porcelain bushings are used extensively in electrical apparatus. Porcelain bushing is the device that enables one or several conductors to pass through a partition such as a wall or tank and insulates the conductors from it. The means of attachment to the partition, such as flange or other fixing device, forms part of the bushing.

Armaflex insulation is black, flexible, closed cell elastomeric nitrile rubber insulation providing a highly efficient method of controlling condensation and insulating against both heat loss and heat gain.
GOOT Vacuum Insulation Panel (VIP) is a new highly-efficient thermal insulation material which was developed in 2006.
The VIP s are constructed using a special technique by inserting the open-celled filler into a centralized sealed barrier.
Using the core material which provides the structural strength and resistance for heat transfer makes the VIP extremely efficient in low thermal conductivity that has less than 0.005w/m.k.
The VIP has been proven to exceed its performance than the conventional insulations by far. Vacuum Insulation panels are our new high- efficient thermal insulation. It is created by inserting the open celled filler into a centralized sealed barrier. The core material provides the structural strength and resistance to heat transfer.

Toughened glass insulators produced Electric provide the highest level of performance and long-term security for high voltage insulation.
MECHANICAL & VOLTAGE RATING
Toughened glass disc insulator 40kN up to 300kN, 11kV up to 765kV.
STANDARD
glass insulators comply with IEC60383.
STRUCTURE
Glass insulator consists of cast-iron cap, toughened glass body and pin which are agglutinated together by cement into an integrated piece. Cylindrical head has been adopted for insulators, which is the most advanced structure in the world with superiorities such as less dimension, lighter wieght, higher strength and longer creepage distance which can save metallic materials and reduce transmission line cost.
Most High-voltage lines use ball & socket type toughened glass insulator, which is also called cap & pin. Cross-section is as below. Tongue & Clevis assembly is also used for glass disc insulator.
Nomal type/Fog type
APPLICATION
Glass insulators are applied in HV and Extra HV transmission lines as dielectric and use for suspending conductors.
Types: Long rod composite insulator, tension & suspension insulator, line post, station post/busbar support insulator
Composite insulator consists of three parts:
Fiberglass core: ECR
End fitting: Hot-dip galvanized forged steel and casting steel.
Silicone rubber: HTV
VOLTAGE RATING & STRENGTH RANGE
11kV up to 500kV. 40kN up to 300kN long rod type, 4kN up to 20kN post type.
STANDARD
TRONCO ELECTRIC insulators complied with the standard of IEC 61109 & IEC 61952
ADVANTAGES
The use of composite insulators in place of traditional porcelain and glass insulators for line insulation has become widespread in the last 20 years. High temperature vulcanized (HTV) silicone rubber is dominating for transmission voltages.

Composite Insulator Classification
According to different installation methods, insulators can be divided into suspension insulators and post insulators; according to the different insulating materials used, they can be divided into porcelain insulators, glass insulators and composite insulators (also called composite insulators). according to different voltage levels, they can be divided into Low-voltage insulators and high-voltage insulators. according to the different environmental conditions used, the pollution-resistant insulators used in polluted areas are derived; according to the different types of voltages, DC insulators are derived. there are also various special-purpose insulators, such as insulating crossarms, Semiconductor glaze insulators and tension insulators for power distribution, spool insulators and wiring insulators, etc. In addition, according to the different breakdown possibilities of insulators, it can be divided into A-type, non-breakable insulators and B-type instant-breakable insulators.
