Profit forecast and investment advice: without considering the additional issuance, we expect the company to make a forecast of 0.14-0.22 yuan per share in 2011-2012. due to the broad market prospect of the superconducting current limiter in the future, the company is the only enterprise in China that can do it and will monopolize the market. give "overweight" investment rating.

Investment risk: at present, the main focus of the company is the superconducting current limiter, and the 220KV superconducting current limiter is the main demand in the future, and its operation and approval of the power grid directly determine the future market promotion of the company. at present, the 220KV superconducting current limiter is in the grid commissioning period, there is a certain uncertainty.
