Note: 1.The mini creepage distance is a little different as per product height.
          2. The product height and top, boltom accessories install dilmension could be choosed from table, also could be supplied their dates to us by yourself.The 220 kVinsulator could be one section, and also two sections.
          3. 110Kv-220kV composite core post insulator only could be applied to busbar post or laleral post.It should be discussed with manufacturer if the products are used for knife switch post.
