Post Insulator
Post Insulator includes Station Post Insulators , Line Post Insulators and Pin Post Insulators
This type is Station Post insulator,it is also called Outdoor solid Core Post insulator.It is used for insulation and support of live parts in outdoor power stations, substations and electrical equipment(disconnector) with a average rated voltage of 10-500kV.
It includes a part of porcelain insulating body and cast iron fittings.Our factory manufactured station post insulator mainly according to standard IEC, ANSI, and some countries have their own standard like Russian, Mexico,and South Africa etc.
The suitable environment for station post insulator is -40℃~ +40℃, and some can be used in areas with an altitude of 4000m. Station Post Insulator is divided into two categories: normal type and anti-pollution type. Anti-pollution type can be used in medium, heavy and heavy pollution areas.
IEC POST INSULATOR
IEC Station Post Insulator is manufacture according to standard IEC 60273 and IEC 60168.Royal Insulators supply IEC Post Insulator that has a rated voltage from 10kV -500kV， BIL voltage from95kV -1800kV， and have Cantilever Strength from 4kN to 20kN.Our IEC Post Insulator is made of C130 material with lighter weight and higher strength.
The insulator material of the unit is made of high quality aluminum oxide porcelain,C130 ,Which conform to Standard IEC 60672.Glazing provides a dirt repellent surface.Glazing is normally brown and grey in color.Semi conductive surface glazing can also be provided for special enviroments.
Fittings are made of malleable cast iron according to according to Standard EN1562 or Spheroidal according to EN1563.
All fittings are hot dip galvanized according to standard EN ISO 1461 with a zinc weight min600g/m2.(min.85um) as average value.
