Lw58-252/T4000-50 High Voltage Sf6 Circuit Breaker

Product introduction

LW58-252/T4000-50 ouldoor self-energy power high voltage SF6 circuil breaker is suilable for the eleclric
power system of AC 50Hz and 252kV. which is the control and prolection equipmenl for lhe electric power
system. as well as for circuil breaker connection.

The product uses SF6 gas as the arc extinguishing and insulation medium. adopting the self-energy power arc
extinguishing double-action-type interrupter structure technique. equipped with new-type spring operating
mechanism.with features of strong switching ability. less operating power. bw noise and high reliability. the
technical indicators have reached similar products in domestic and intemational advanced level.

Three-phase SF6 circuit breaker. which is operated by one mechanism lor one pole. is changed to three-phase
mechanical linkage circuit breaker which is operated by one mechanism. The decrease of mechanism improves
the linkage reliability lor three-phase SF6 circuit breaker to avoid lack of phase operation.

Main characteristic
