Detailed Description

230kV Composite Polymer Insulator 120kN With Socket And Ball And 2 Corona Rings CHARACTERISTICS: (1)The silicon rubber shedsdesigned according to the aerodynamics principle,use the whole-moulding methodto make sure the validity of total creepage distance under every climate and nasty conditions, as well as improvethe pollution discharge of the insulators. (2) The corerod uses the ECR high-temperature and acid-proof material. (3) The end fittings connection adoptthe zinc cover protection, supersonic monitor and coaxial constant compression controlled by computer, finished with good appearance and high quality.
