            35kV-1200kV AC Composite Hollow Insulator/±400kV-±1100kV DC Composite Hollow Insulator
            • Description
            • Parameter

            Structure: composed mainly of glass fiber reinforced plastic sleeve, high temperature liquid silicone rubber (LSR) sheds and alloy flange.

            Features:

            1) Made of non-brittle materials with excellent explosion-proof property;

            2) Excellent hydrophobic of LSR will result in almost no maintenance;

            3) Strongly resistant to leakage tracking (4.5 kV) and galvanic corrosion;

            4) Small weight and excellent seismic performance, easy for transportation and installation;

            5) Long service life, stable and reliable quality and short delivery time.

            Product application:
             
            After the type test of 1100kV hollow insulator was completed in 2007, a series of products were developed according to the requirements of users. The ± 1100kV composite hollow bushing was successfully sold to snivent in early 2013.
