Pollution Performance of Composite Hollow Core Insulators with HTV & LSR Housings

The properties of silicone rubber make it an ideal shell for composite high voltage outdoor insulators.These include stability against UV rays and ozone;Good dielectric properties, not affected by temperature changes;Combustion non-toxic products;Excellent hydrophobic recovery and transfer to the pollution layer;High arc resistors comply with IEC 61621 and high tracking resistors comply with IEC 60587.High temperature vulcanized silicone rubber is commonly used in the casing of large composite hollow insulators, which are manufactured using extrusion technology, and hollow and solid insulators which are manufactured using injection molding technology.In contrast, LSR rubber is commonly used in the casing of large composite hollow insulators made by injection molding technology.
