Lapp porcelain post insulators

 Lapp porcelain post insulators can be used for extra high voltage and high voltage substations, such as 1000kv post insulators with high mechanical strength.

Lapp porcelain post insulators

Lapp porcelain post insulators are made from high quality aluminum oxide porcelain, conforming to IEC 60672. Lapp porcelain post insulators shall be glazed in brown or grey. The glaze forms a protective dirt repellent layer on the surface of the insulator.

The end fittings of Lapp porcelain post insulators
◆ All fittings are hot dip galvanized as per IEC and ANSI standards
◆ Made from stainless steel, aluminum and iron
◆ Threads are generally tapped after hot dip galvanizing
◆ The insulator shall be installed with bolts, nuts and others

The models of Lapp porcelain post insulators are glazed (brown or grey color) and fired in fully automated kilns where thorough vitrification is assured. High voltage porcelain post insulators shall be installed with grading rings.

100kv Lapp porcelain post insulators are used with one grading ring, above 220kv porcelain post insulators used with two suitable grading rings.
