300kN DC suspension porcelain insulator XZWP-300 (U300B)

300kN DC suspension porcelain insulator XZWP-300 (U300B)

DC disc suspension porcelain insulators are used on HVDC transmission lines to support and insulate conductors. The insulators can be used in heavy polluted area with reasonable shed profile design, the porcelain material has superior characteristics to resist DC ageing, and pins with zinc sleeve can prevent DC electrolytic corrosion. The main E&M performance has reached international advanced level.


The following suspension insulator comply with the IEC standard. The glaze color of the insulator are brown or light gray.
