1.Station Post Insulator ,(also called Solid core post insulator, bus support insulator,support rod insulator etc) is one type of the electrical insulator which is used in substation as part of the disconnect switch. It includes a part of porcelain insulating body and cast iron fittings.there are standards like IEC, ANSI, and some countries have their own standard for statoin post insulators like Russian, Mexico,and South Africa etc.
2.Our Porcelain Station Post Insulators are manufactured with a cantilever strength from 4kN to 20kN. Rated Voltage from 10kV to 1100kV
3.Our IEC Standard Porcelain Station Post Insulator have C4-125,C6-125,C8-125,C10-125, C4-150,C6-150,C8-150,C10-150,C4-170,C6-170,C8-170,C10-170,C4-200,C6-200,C8-200,C10-200,C4-250,C6-250,C8-250,C10-250,C12.5-250,C4-325,C6-325,C8-325,C10-325,C4-450,C6-450,C8-450,C4-550,C6-550,C8-550,C10-550,C12.5-550,C16-550,C4-650,C6-650,C8-650,C10-650,C12.5-650,C16-650,C20-650,C4-750,C6-750,C8-750,C10-750,C12.5-750,C6-950,C8-950,C4-1050,C6-1050,C8-1050,C10-1050,C12.5-1050,C6-1300,C8-1300,C10-1300,C6-1425,C8-1425,C10-1425,C6-1550,C8-1550,C10-1550,C12.5-1550,C8-1675, C10-1675,C6-1800,C8-1800, C10-1800, C10-2100, C10-2550 etc.
4.Our ANSI Standard Station Post Insulators have: TR202,TR205,TR208,TR210,TR216,TR287,TR286,TR288,TR304,TR306,TR316,TR324,TR-362, TR-369, TR391 etc.
5.Royal Insulators is one of the strongest manufacturer of porcelain station post insulators in China and supply to the largest switchgear company in China and some large company in Europe and USA. We have type test reports for IEC standards and ANSI standards which are done in authorized lab known all over the world. We can produce post insulator as per customer requirement and design for them.Experienced technicians are always on line for help with fast respond.
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.
