Installation Manual

Product information
Introduction
Eaton’s Cooper Power Systems 600 A 15/25 kV Class
deadbreak connectors are used to terminate high-
voltage underground cable to deadfront apparatus such
as transformers, switches, and switchgear. They are fully
shielded, submersible, and meet the requirements of the
IEEE Std 386™ standard— “Separable Insulated Connector
Systems”. Eaton’s Cooper Power Systems 600 A deadbreak
connectors are fully interchangeable with all other
manufacturers that also certify compliance with the IEEE
Std 386™ standard. The DT625 is rated for 900 A when
used with all copper current carrying components.

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. When
additional information is desired to satisfy a problem not
covered sufficiently for the user’s purpose, please contact
your Eaton’s Cooper Power Systems sales representative.
Acceptance and initial inspection
Each deadbreak connector is completely inspected and
tested at the factory. It is in good condition when accepted
by the carrier for shipment. Upon receipt of a deadbreak
connector, inspect it thoroughly for damage and loss
of parts incurred during shipment. If damage or loss is
discovered, file a claim with the carrier immediately.
Handling and storage
If the deadbreak connector is to be stored for an appreciable
time before installation, provide a clean, dry storage area.
Quality standards
ISO 9001-Certified Quality Management System
DANGER
All associated apparatus must be de-energized during
any hands-on installation or maintenance. Failure to
comply will result in death, severe personal injury and
equipment damage.
WARNING
The 600 A DT625 T-body is designed to be operated in
accordance with normal safe operating procedures.
These instructions are not intended to supersede or
replace existing safety and operating procedures. The
elbow connector should be installed and serviced only
by personnel familiar with good safety practices and
the handling of high-voltage electrical equipment.
WARNING
Optional Capacitive Test Point Operating Instructions:
Use only voltage indicating instruments specifically
designed for test points. Use of conventional voltage
sensing devices may provide false “No Voltage”
indications.
The test point must be dry and free of contaminant’s
when checking for voltage. After indication is taken:
clean, dry, and lubricate the test point cap with silicone
grease and assemble to the test point.
The capacitive test point is not sufficiently accurate,
nor is it intended for, actual voltage measurements or
phasing operations.
A reading of no voltage from the test point should
not be the only indication of a de-energized circuit
obtained before touching the connector. Other
procedures can include direct conductor voltage testing
or grounding using a live-line tool.
