a full range of group operated
disconnect switches for substation switching applications, including
center-break, center "Vee", and
double end-break. All
switches are available in both parallel insulator and Vee insulator
Voltage ratings for most SEECO disconnect switches range from 15 to
230 kV and all switches can be supplied with continuous current
ratings of 600, 1200, and 2000 amp. All switches except the
vertical break have copper live part construction. Check the
individual web pages and catalog literature for the ratings of each
SEECO vertical break is available in both aluminum
and copper. The voltage range is 15 to 345 kV with available
current ratings of 600, 1200, 2000 and 3000 amp. SEECO plans
to extend the voltage range to 500 kV and the current rating to 4000
amp in the future.
Typical applications for SEECO substation switches include high side
and by-passing breakers, bus sectionalizing, and isolating
arrestors, metering equipment, and other apparatus.
SEECO substation switches have over 40 years of proven field
experience. Each switch configuration is designed for
maintenance-free operation in extreme environmental and operating
conditions. The operating effort to open and close the
switches is minimal, even at higher voltages. The switch
design employs a positive toggle when in the fully closed position,
so the switch stays closed under adverse conditions, such as
excessive structure deflection, vibration, seismic events, and high
current or momentary conditions.
All substation switches can also be supplied with other complementary SEECO products, including
operators, pre-assembled trusses, vacuum interrupters, ground
externally mounted auxiliary contacts.
