SEECO three-way, 69 kV phase-over-phase switch with three bottle vacuum interrupters, motor operators and SEECO voltage sensors. Multi-way switches utilize a ‘bundling’ concept, with shared insulators, switch components and interrupters, significantly reducing the cost of sectionalizing ‘per way’ when compared to multiple single way switches on separate pole structures.

SEECO unitized, phase-over-phase 115 kV vertical break switch with our high velocity whip (HVW).  Compact phase spacing reduces pole height and cost.  Unitizing reduces installation time and cost, and ensures reliable operation and long life.

SEECO one-way, 69 kV phase-over-phase switch with three bottle vacuum interrupters, mounted in a delta configuration.  The delta mounting arrangement minimizes phase spacing and overall pole height and cost.

SEECO 345 kV vertical break switch.  Live part construction is fabricated bar stock and current path is fully segregated from mechanical linkages that rotate and raise or lower the blade.

SEECO unitized 69 kV three-way phase-over-phase switch offloaded at job site.  Our unitized single and multi-way switches are fully factory assembled and adjusted for three phase operation, including synchronous clocking of all three phases and correct ‘toggle’ in the closed position.  Unitizing reduces installation time and cost by 30% – 50%.

SEECO 230 kV combination current and voltage line sensors, a key component of this substation’s relay and protection scheme.  Lightweight, oil-free, environmentally friendly.

SEECO unitized 115 kV vertical break switch with four bottle vacuum interrupters and worm gear operating mechanism.  This switch was fully factory assembled, adjusted and shipped on a SEECO-supplied truss assembly.  Unitizing substantially reduces field installation time and cost, and ensures reliable operation and long life.

SEECO 115 kV unitized vertical break switch with four bottle vacuum interrupters, motor operator and voltage line sensor.  This automatic throw-over application will open and close upon gain or loss of potential, greatly reducing outage duration and restoring the associated load quickly.

SEECO motor operators in a remote location, where 120 VAC is not readily available.  Power is provided by an optional SEECO solar power supply, which includes batteries, DC charge controller, solar panels, mounting bracket and separate enclosure for battery storage.

SEECO 115 kV center Vee switches, mounted both vertically and horizontal upright on this customer’s A-frame structure.  The small footprint of SEECO center Vee switches minimizes mounting structure size and cost, while the direction of the break minimizes overhead clearance requirements.
