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.
