Types: Porcelain disc insulator/suspension insulator, pin insulator, line post insulator, station post insulator. DISC INSULATORS Porcelain disc insulators are the most widely used in strings, they can be used for any voltage depending on the numberof units mounted in series for transmission and distribution lines. Voltage & Mechanical Range 11kV-765kV. 40kN-300kN. Application The insulators are designed to be suitable for different types of polluted zones and mechanical strength according to client's requrests. Life expectancy of these insulators are extremely high but may be adversely affected if operated beyond specified limits of electrical or mechanical stress. STATION POST INSULATOR the most comprehensive range of porcelain post insulators up to highest system voltages with the most progressive technology, engineering and life time. Short production time, tighter tolerances, flexible design, extra-high mechanical strength and extended creepage distances are possible by wet/dry process. Voltage Range IEC station post insulators manufacture in full accordance to IEC60273. Operating rod columns for disconnectors are manufactured corresponding to the relevant post insulators. Insulation requirements are available in ratings from BIL 60kV to 2550kV. TR station post insulators manufacture in full accordance with ANSI C29.9. Insulation requirements are available in ratings from 95 kV to 2050 kV. Special requirements can be also offered upon request. Standard post insulators conforms to specifications of IEC 60273 and ANSI-C29.9. Application The post insulator up to 500kV can be used for switchgears, disconnectors and substations.

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. Lighter weight Lower cost Easier handling Better resistance to damage from vandals Superior contamination performance APPLICATION Long rod insulators are used for suspension and tension towers for high voltage grids and railway grids. Composite post insulators are used for disconnector, switchgear and substation works. Tronco Electric can also make the design and supply the insulator strings.
