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.
