Ac Disc Porcelain Insulators (Normal Type)

Product Detail

Standard: IEC60383 Voltage:6-33kV Suspension insulators are available for ball & socket or clevis-tongue coupling. Standard caps are constructed of hot-dip galvanized malleable iron. Cotter keys for locking ball & socket and clevis pin connections are stainless steel. The normal type disc suspension insulators include standard type and large creepage distance type, which are widely used in clean area and light pollution area. Disc suspension porcelain insulators are mainly used on high-voltage overhead transmission and distribution lines to support and insulate conductors. The normal type disc suspension porcelain insulators include standard type and large creepage distance type insulators, which are widely used in clean areas and light pollution areas.
