The Universal Medium Voltage Termination System
for Polymeric and Paper Insulated Cables
Over the last three decades, engineers in utilities and industry around
the world have specified million’s of
Raychem cable terminations at
distribution voltages up to 36 kV.
Raychem terminations have become
identified with reliability because of
their unparalleled long-term performance – where it really counts – in
the field. Today there are many
changes influencing the distribution
of power at medium voltages. For
example, the transition to new types
of polymeric cable, distribution at
higher voltages, and the widespread
usage of compact switchgear.
Anticipating these industry changes,
we have continued to extend and
improve the product range, based on
the extensive experiece both in the
field and at our outdoor test sites in
polluted and desert environments.
Now these developments are
incorporated in a new generation of
Raychem heat-shrinkable cable terminations, that are even easier to select
and install, without compromising
the reliability of proven materials
technology. The improved system is
simple to use, because the basic termination components and installation
steps are the same – even if your network operates with voltages of 7.2 to
36 kV; if you use 12 kV belted paper
cable and 24 kV water-blocked single
core polymeric cable; whether you
make equipment connections in a
cable box or in compact switchgear.
Let’s review the main advantages of
the improved system:
Universal Selection Procedure
• Simplifield selection table allows
quick selection based on conductor
cross section and voltage class for
either polymeric or MIND paper
insulated cables (For MI draining oil
cables, contact your local representative)
• Simple modification codes permit
easy specification of optional
accessory kits
• Enhanced range-taking ability
means that one kit fits more conductor sizes, reducing stocking
requirements
• Unlimited shelf life allows stocking
of economic quantities without
product spoilage
Simplifield Cable Preparation
• Improved treatment of screen cut
back is compatible with all state of
the art screen removal techniques
• No tapering of insulation required
• No polishing of polymeric insulation
surface
• No special preparation of sectored,
or eccentric conductors, or of cable
that is curved after unreeling from
the cable drum
• Cable preparation steps are similar
to those for Raychem joints
Simplified Installation
• Components are lightweight and
non-shattering
• Clear instruction sheets
• Common installation procedure for
polymeric and MIND paper cables
• Factory engineered kit permits rapid
on-site installation
• No mechanical stress at insulation
screen cutback
• Termination accommodates same
bending radius as cable
• Visual confirmation of correct
assembly sequence possible after
installation
• Rain skirts can be installed to allow
either top or bottom feed
• No soldering of earthing accessories
required
Outstanding Long-Term Reliability
• Fully sealed against water ingress
from the environment or from within
the conductor strands
• Polymeric materials load cycle with
the cable without mechanically
stressing termination components
and sealants
• Unsurpassed performance in
polluted environments, proven
over three decades.

Boots
Insulating boots are moulded parts
which are shrunk over the connection
between the cable lug and bushing to
insulate them. They are used in
switchgear and transformers with
compound filled boxes where the
clearances are insufficient for
operation in air or to protect against
flash over due to rodents or extreme
humidity.
A full range of insulating boots are
available up to 17.5 kV. These can be
ordered separately by quoting the
part number or with the termination
by adding a mod code to the end.

The insulated adapter termination
system provides perfect sealing,
electrical insulation and an electrical
connection between Raychem terminations and SF6-insulated switchgear
up to 24 kV.
Its lead-in insulator (630 A) conforms
to DIN 47636 and ANSI IEEE 386.
The cable box of the switchgear
must be provided with suitable
protection against electric shock.
The insulating adapter is compatible
with all Raychem terminations.
Details of the terminations can be
found in the cable accessories
catalogue.
Thick walled insulator made of high
quality elastomer with sealing face
over the termination, bushing cone
and plug.
The electrical connection is made
with a terminal stud and the cable
lug of the termination. Two cable
connection is possible. A special plug
which allows cable testing without
disconnecting the adapter is also
offered. The design of the adapter
for connecting the surge arrester is
basically identical. The elastomer
insulator has an additional lead-in
duct for the surge arrester. Details
of the surge arresters can be found
in the brochure EPP 0533.
A thick walled, heat-shrinkable
insulating sleeve provides a
hermetic seal over the cone of
the bushing and the termination.
The adapter area is smoothed
with a meltable filler strip.
The insulating body, fixing bolts, terminal stud and backplug are supplied
in a 3-phase set complete with installation instruction. Cable lugs and
terminations are not included.
For double T-connections, the second
adapter is of special design and
includes connection plug, insulating
body, fixing bolts, terminal stud and
backplug. It can be combined with
first adapters of type RICS-57x3-CU
with M16 lugs, but not with adapter
for surge arresters type RICS-51x9
Scope of supply (for three phases)
Heat-shrinkable insulating sleeving,
filler strip, small accessories and
installation instructions. Terminal
stud and lug must be enclosed.
Scope of supply (for three phases)
Insulator, plug, terminal stud, small
accessories and installation instructions.

RCAB – Elastomeric insulating bushing boot
for bushings up to 17.5 kV and 24 kV
RCAB right angle or inline
application up to 17.5 kV
Raychem elastomeric insulating
boots are moulded parts which fit
over the connection between the
cable lug and the inline or rightangled equipment bushing to
improve phase-to-phase and phaseto-ground insulation. They are used
in switchgear and transformer cable
boxes where the air clearances are
insufficient for normal operation,
or to protect against flashover due
to rodents or high humidity.
The non-tracking elastomeric
housing has excellent erosion
resistance, dielectric properties and
environmental resistance, giving
superb per-formance in areas of
high humidity and electrical stress.
RCAB inline application up to 24 kV
RCAB boots works in combination
with all Raychem termination product
lines including both elastomeric and
traditional heatshrink technology.
RCAB boots are quick and easy to
install and do not require any taping
of the bushing or the termination.
The boot can easily be removed
and reinstalled without the need
for additional material or tooling,
allowing access to the bushing
connection for test purposes.
The universal screw EXRM-1366 is
available on request.
The insulating body is supplied in a
3-phase set complete with installation
instruction. Fixing bolts, terminal stud
and cable lugs are not included.
Terminal studs with a M16 thread can
be ordered separately as EXRM-1366.
The adapter is to be used in combination Raychem teminations.
Each kit contains elastomeric
insulating boots, collars (if required)
for three phases and installation
instructions.
