\"SKM-12<\/p>\n

Product Overview<\/h3>\n

The spring operating mechanism adopts an independent design from the frame. It can be used either as a fixed installation unit or assembled with a withdrawable truck to form a draw-out unit. It features long service life, simple maintenance, no pollution, no explosion risk, and low noise, and is suitable for harsh working conditions such as frequent operations.<\/p>\n

Product Features<\/h3>\n
    \n
  • The spring operating mechanism adopts an innovative modular design.<\/li>\n
  • Optional phase spacing and pole spacing to meet various special requirements.<\/li>\n
  • Stable mechanical and electrical performance, high reliability, with a mechanical life \u2265 30,000 operations.<\/li>\n
  • The operating mechanism can be equipped with an online monitoring system for mechanical characteristics.<\/li>\n<\/ul>\n
