Sediver toughened glass insulators With more than 50 years of successful experience in the US from coast to coast and over 500 million of insulators in service worldwide, Sediver is the proven world expert in transmission insulator technology. Sedicoat RTV coated glass insulators – the solution for extreme pollution Silicone coated glass insulators combine excellent pollution performance and the technical merits and reliability of toughened glass insulators. This product eliminates the risk of pollution related flashovers and the need for periodic washing.
Sediver High Resistivity glass insulators for HVDC applications Insulators used on HVDC lines have to sustain very unique and specific stress conditions associated with the unidirectional e-field and current flow. To achieve an optimum performance in DC and to cope with its specific constraints, Sediver developed an exclusive technical solution: the High Resistivity Toughened Glass insulator.
