UltraSIL polymer-insulated D-73P disconnect switches installation instructions
●Introduction
◆Service information MN008004EN covers installation of Eaton’s Cooper Power™ series D-73P, D-73P-CD, D-73P-LT, and D-73P-TS disconnect switches.
◆The D-73P line of disconnect switches are single phase-operable switches to sectionalize or isolate overhead lines on electrical distribution systems up to 38 kV. It is for manual switching of de-energized parallel circuits of overhead lines on electrical distribution system. The D-73P switches have no current making or breaking ability. The switches can be mounted in wide variety of positions depending on style and mounting brackets purchased. Many terminal connections are available to customize switch to user’s need.
◆Eaton’s D-73P-CD single insulator cutout disconnect switches are hookstick operated switch designed for operation at 600 A and 900 A on overhead distribution circuits rated up to 38 kV, 150 BIL. The cutout disconnect switch is designed for riser pole application where the switch is easily installed with included cross arm bracket much like a standard cutout.
◆The D-73P-TS style switch is an in-line disconnect switch used to manually switch de-energized or parallel distribution circuits of 15kV through 38kV 200BIL. The D-73P-TS switches are rated at 600 and 900A continuous and may be applied directly into the line wherever line sectionalizing is desired.
◆The D-73P-LT single insulator line-tap disconnect switch is an in-line single-phase hookstick-operated switch designed for operation at 600 and 900A on distribution circuits up to 38kV, 150kV BIL. The switch is designed for use in feeder tap, sectionalizing, and devise isolation applications. The switch can be installed under existing line for tap applications without cutting the conductor or it can be cut into the distribution line for sectionalizing applications.
●Read this manual first
◆Read and understand the contents of this manual and follow all locally approved procedures and safety practices before installing or operating this equipment
●Additional information
◆These instructions cannot cover all details or variations in the equipment, procedures, or process described nor provide directions for meeting every possible contingency during installation, operation, or maintenance.
