Eaton 600 A 35 kV Class Insulated Standoff Bushing User manual

600 A 35 kV class PUSH-OP®
deadbreak connector
General
Eaton offers a complete threadless deadbreak,
clampstick operable connection system with
its Cooper Power™ series 600 A, 35 kV
class PUSH-OP®deadbreak connector for
terminating underground cables to transformers,
switches, switchgear, and other apparatus. It
is fully shielded, submersible, and meets the
requirements of IEEE Std 386™-2006 standard –
Separable Insulated Connector Systems.
The design employs a unique, 600 A rated, plated
copper probe and mating PUSH-OP bushing
utilizing a plated copper finger contact system.
The PUSH-OP connector's stainless steel latching,
linkage mechanism provides leverage for easy
disconnection of the terminator and easy handling
of heavy cable. The result is a one-person,
clampstick operable connection system that is
unequalled in ease of operation and time required
to perform sectionalizing operations.
A coppertop compression connector is provided
for terminating the conductor.
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 Eaton's Cooper
Power series M.O.V.E. arrester or grounding
elbow. The grounding elbow may be continuously
connected to the PUSH-OP connector while
moving it to and from an apparatus bushing.
Eaton offers an optional capacitive test point similar
to test points on 200 A elbow connectors. This allows
use of Eaton's Cooper Power series test point faulted
circuit indicators.
The PUSH-OP connector also has a non-bolted
connection that eliminates threading and its
associated problems.
PUSH-OP connectors are designed for use on solid
dielectric cable (XLPE or EPR) with extruded semi-
conducting shields and concentric neutral, with or
without jacket. Installation on jacketed concentric
neutral cable may require additional sealing
material. Cold shrinkable adapters are available for
tape shield, linear corrugated and drain wire cable
adaption for use with deadbreak connectors.
Installation
The T-body housing with stainless steel shroud is
assembled onto prepared cable with a threaded
coppertop spade lug compression connector. The
loadbreak reducing tap plug is threaded into the
connector and onto a probe using an alignment
tool, installation torque tool, and T-wrench.
The assembled housing is then connected to
a de-energized 600 A PUSH-OP type bushing
interface and bracket using a clampstick without
any threading operation. (See Table 5 for
information on tools.) Refer to Service Information

Connector Installation Instructions for details.

Catalog number selection
Use the following procedure to develop the correct part number for
the desired PUSH-OP kit, based on cable size, conductor size and
desired options.
Step 1 – Determine the cable’s diameter over the electrical
insulation as shown in Figure 3 (including tolerances). Then identify a
cable range from Table 3 that brackets the minimum and maximum
insulation diameters. Select the correct CABLE RANGE CODE.
Step 2 – Identify the conductor size and type in Table 4 and select
the CONDUCTOR CODE from the far right column.
Step 3 – For a PUSH-OP kit with a capacitive test point and
protective cap, order:
For a PUSH-OP kit without a capacitive test point or protective cap,
order:
EXAMPLE: To select a PUSH-OP kit without a capacitive test point,
with a protective cap for a 250 kcmil compressed cable with a
nominal insulation diameter of 1.16".
Step 1 – Nominal diameter over the insulation is 1.16" ± .030"
minimum diameter = 1.16 - .030 = 1.13"
maximum diameter = 1.16 + .030 = 1.19"
From Table 3 identify the cable range 1.13" - 1.19" and select the “H”
Cable Range Code.
Step 2 – The conductor size is a 250 kcmil compressed. From Table
4, under the column “Concentric or Compressed”, identify 250 kcmil
and select the “17” conductor code.
Step 3 – Order catalog number:
