    Introduce of 220kv composite insulator
    1.End fitting is made of special steel. With labyrinth design at the terminal, the sealing performance is excellent under multi-layer protection.
    2.The end fitting is connected with core under the most advanced computer controlled coaxial constant pressure crimping process.
    3.The housing & weather sheds adopts the one-time integral molding process under high temperature and high pressure.Insulator factory
