Porcelain suspension insulators fall into two types: AC and DC. The high-resistance insulating material formula, special umbrella structure, and anti-corrosion design of metal attachment make the AC porcelain insulators produced by the company fully meet the harsh requirements of DC power transmission on product performance. The varied umbrella-type structural designs of porcelain suspension insulators provide a wide range of reasonable options for line use in different areas. -Normal-type Porcelain Suspension Insulator -Bell-type Suspension Porcelain Insulator -Double-shed and Tri-shed Porcelain Suspension Insulators -Straw Hat Type Porcelain Suspension Insulator -Ground Wire Insulator Composite insulatorsWe can supply 35kv to 1000kv AC/DC suspension composite insulators with the annual capacity of 600,000 standard pieces. And can also supply composite insulators of other types, such like pin type, post type, partition rod, as well as some used on railway, light train and live-wire etc.
