Porcelain Insulator Plant Invests in Expanded Production Capabilities

The past two decades have seen the marketplace for high voltage porcelain insulators impacted by intense global competition as well as a serious challenge from hollow core composite technology. At the same time, the growing number of HVDC and UHV AC and DC... Read More

Optimal Dimensioning of Grading Rings for Composite Insulators

One of the most important parameters for composite insulators is hydrophobicity, allowing superior insulation performance compared to ceramic cap & pin strings. However, these initial hydrophobic properties can deteriorate in service if there is... Read More

High Voltage Insulator Coatings: State-of-the-Art & Future Development

A HVIC Symposium organized by the Gulf Co-operation Council Interconnection Authority (GCCIA) was held in Dammam, Saudi Arabia this past February. Following upon an earlier such Symposium organized in Avellino, Italy last October, this next event again... Read More

Coating Porcelain Line Insulators to Prevent Pollution Flashover

The Gulf State of Kuwait is nestled in one of the driest places on earth. A highly urbanized country, it is also one of the highest per capita consumers of energy, mostly for the oil and gas sector as well as for air conditioning and water desalination... Read More

Coating Line Insulators with RTV Silicone

Study of RTV coatings to combat pollution flashover of line insulators began in China during the early 1980s, with the first trial application in 1986 when Tsinghua University in Beijing co-operated with the Tianjin Power Bureau and applied coatings to 15... Read More

Non-Soluble Surface Deposits on Insulators

High voltage engineers well understand that insulators usually remain quiescent when dry – even if highly polluted. However, they can quickly light up with partial discharge activity once dirty surfaces are wetted by rain or condensation. The extent of such... Read More
