Description
Scada-Mate SD switches are three-pole, group-operated
interrupter switches rated 900 amperes continuous and
interrupting. They are offered in voltage ratings of 14.4 kV
and 25 kV. Scada-Mate SD switches feature a five-time
duty-cycle fault-closing rating of 12,500 amperes, RMS,
symmetrical. Circuit-making and circuit-breaking are
accomplished internally within a vacuum interrupter
bottle encapsulated in a solid dielectric S&C Cypoxy™
Insulator module. Interrupter position is clearly visible
on the OPEN/CLOSED indicator on the side of the switch.
Scada-Mate SD switches are specifically designed for
automation of overhead distribution systems. They are
factory-assembled on a one-piece base and include an
integral stored-energy operating mechanism. In addition
to electrically operating the interrupters, the operating
mechanism provides nonelectrical mechanical opening
and closing of the interrupters by means of a manualoperation
pull-ring. The switch can be locked open to
prevent electrical or manual closing.
Scada-Mate SD switches are available in compactcrossarm
upright, compact-crossarm upright with extra
mounting-pole clearance, compact-crossarm upright
compact (alley arm), and compact-crossarm tiered
outboard models.
All models feature Cypoxy Insulators.
Arrester mounting brackets are provided as standard
on one side of the switch. A single-point integral lifting
tab is provided for convenient rigging and hoisting.
Scada-Mate SD switches are shipped in heat-treated
(kiln-dried) wooden crates.
