1 general state
GW 4-15 and GW 4-15 TQ and GW 4-20( D), 4-20 GW TQ( D) the type outdoor alternating switch-disconnector of high voltage let have voltage have no load , divide join circuit 。
4-15 GW / 50200 and 4-15 GW TQ/50 200 type industrial railway lines stop up voluntarily the use of pilot device.
4-15 GW / 400 and 4-20 GW( D )/400, 4-15 GW TQ/400 and 4-20 GW TQ( D )/400 type supply power for railway station site route use .
GW 4-20( D )/50 to stop up voluntarily 200 and 4-20 GW TQ( D) 50 rod operation with the 27.5 generator vehicle kV lines of high voltage200 type may be used the 10 kV line of high voltage join .
GW 4-15 , 4-15 GW TQ , GW 4-20( D) , 4-20 GW TQ( D ) type the technical data of switch-disconnector see its performance of Table 1 accord with country to mark GB stipulate in 1985.
