COOPER POWER

™
General
Eaton terminates high voltage underground cable
to transformers, switches, switchgear, and other
apparatus with its Cooper Power™ series 600 A,
25 kV Class T-OP™ II deadbreak connector. It
is fully shielded, submersible and meets the
requirements of IEEE Std 386™-2006 standard
–"Separable Insulated Connector Systems" .
The 200 A three-phase rated loadbreak interface
provides a means for obtaining a live test, visible
ground and visible break using a clampstick.
It also provides a convenient location for an
Eaton's Cooper Power series M.O.V.E. arrester or
grounding elbow.
Eaton offers an exclusive optional capacitive
test point similar to test points on 200 A elbow
connectors. This allows use of test point reset
(TPR) faulted circuit indicators.
T-OP II connectors are designed for use on solid
dielectric cable (XLPE or EPR) with extruded semi-
conducting shields and concentric neutral, with or
without a jacket. Installation on jacketed concentric
neutral cable may require additional sealing
material. Adapters are available for terminating
tape shield and drain wire jacketed cable.
Installation
The T-body is assembled onto prepared cable with
a threaded coppertop compression connector and
using a T-Wrench, the loadbreak reducing tap plug
is threaded into the connector. The short end of a
special copper alloy stud, provided with the kit, is
threaded into a de-energized 600 A bushing. The
assembled housing is then con nect ed to the ap pa-
ra tus bushing using an O&T tool (with cap) and an
installation torque tool.
The T-OP II connector's unique captured rotating
nut provides ease of removal of the T-OP II
connector system from the apparatus bushing.
