Technical characteristics

STE1 and STE3 series are ceramic sealing structure, adopting magnetic blowing plus hydrogen gas arc extinguishing technology: the products have large control capacity and higher reliability.

STE2 series is epoxy sealed structure, adopting magnetic blowing and inert gas arc extinguishing technology, more reliable contact performance.

Mature structure and process: large-scale mass production, better product consistency.

Advanced brazing sealing technology: small sealing stress, lower air leakage rate.

Unique alloy contact material formula: lower contact welding rate.

High-temperature degassing technology: more stable long-term working performance, better voltage resistance and insulation level.
