A. The products are purely solid structure and they do not need to fill any oil medium or gas medium, so they will not leak any oil or gas. They will not pollute the environment in the operation and do not need maintenance.

B. The insulation margin of the bushing is large and they use the semiconductor as the capacitive screen which improves the corona inception voltage greatly.

C. They are made of flame resistant and insulation material and they do not decompose. Their electric property is stable and does not have the danger of combustion and explosion and they will not influence and do damage to other equipments during the operation.

D. The compact construction and silicon rubber housing with small size and light weight is convenient for safe transport and they can be installed at any angle.

E. The products are twined by epoxy glass fiber and use optimal mechanical layer tay-up design. The flexural strength is high and the mechanical property is excellent. They are especially suitable for heavy earthquake area for its anti-seismic conditions (g≤1).

F. The material characteristics of products determine the area of products that can resist great changes of the temperature. The highest temperature is 155 ℃ and the lowest temperature is 200 ℃ below zero.

G. The antifouling property of silicon rubber sleeve is excellent and the products are mainly used in the area with heavy pollution. So there are a lot of DC bushing have been widely used in Shanxi coal power system.

H. The products provided with the above advantages and we can guarantee its long service life and the low cost of the long-time running.

I. The cycle of production is short. They can be designed and produced according to the different operating requirements of customers and they are flexible and quicker.
