Bodies –
Standard bodies are made of cast aluminum painted gray. Cast
brass bodies are available. A plated steel vent plug is standard
and is threaded into the body to permit displacement of the
internal insulating material during cable insertion.
External Insulation
– Slip-on terminators utilize a high strength, wet process
porcelain with excellent mechanical and electrical characteristics.
Deep draw corrugated skirts provide the necessary creepage
and strike distances and permit installation in either upright
or inverted positions, indoors and out. Porcelains are gasket
sealed to the body of the terminator.
Stress relief
– Factory installed, internal stress relief devices
control electrical stress without having to build a taped
stress cone on the cable. The device is shaped to permit smooth
entry of the cable while assuring continuous contact around
the cable shielding system.
Sealing system
– Hoods are gasketed and spun on to the top of the terminator.
Sealing bolts prevent leakage of the internal insulating material.
A silicone rubber diaphragm provides a positive seal at the
cable entrance of the terminator. A bolted cast aluminum sealing
plates holds the rubber diaphragm in place.
Internal insulating
material – Slip-on terminators are factory filled
with an exclusively formulated insulating material (Novoid
254) which eliminates the need for heating and pouring of
compounds in the field. The soft, tacky material has a dielectric
constant (SIC) which closely approximates that of polyethylene
providing a dielectrically compatible system with the cable.
The insulating material creates a void-free environment around
the prepared cable end and permits acceptance of a wide range
of cable sizes. Some physical and electrical characteristics
are:

249°C |

Cable centering plug
– A cable centering plug is included with each termination
to provide a snug fit at the cable entrance for small diameter
cables.
Adapter kits
– Slip-on terminators are designed for polyethylene
insulated, URD cables. To terminate paper or varnished cambric
insulated, lead sheath cables or shielded, jacketed cables
having rubber or polyethylene insulation one of the following
kits must be used.
“K” Adapter
Kit – or polyethylene or EPR rubber insulated,
shielded, jacketed cables or lead sheath cables not requiring
a wiped joint. A “K” kit adds approximately 2
3⁄4” to the length of the terminator. K1 kits
include a ground strap, tension spring, rubber sealing boot,
housing and mounting hardware. K2 and K3 kits consist of the
same as a K1 except that a rubber cushion strip and band clamp
is used instead of a tension spring.
“W” Adapter
Kit – For polyethylene or EPR rubber insulated,
lead sheathed cables where a wiped joint is required. The
kit consists of a brass wiping sleeve with molded rubber gasket.
A ground boss with a 1⁄2”-13 tap is provided on
the sleeve.
“PW” Adapter
Kit – For paper or varnished cambric insulated,
lead sheathed cables where a wiped joint is required. The
kit consists of a “W” series kit combined with
Teflon® tape for protection
of the paper or varnished cambric tape during installation.
Connectors
– Connectors are compression style available in either
copper or aluminum. Compression connectors are required for
both eyebolt and hood style terminations. Cooper connectors
are made of high conductivity copper and are for use on copper
conductor cable only. High conductivity aluminum connectors
are tin plated and are for use on aluminum conductors through
1250 kcmil and copper conductors up to 250 kcmil as standard.
The aluminum connectors are internally coated with a conductive
oxide inhibiting compound for proper connection to aluminum
conductors.
Aerial lugs
– Two different aerial takeoff constructions, an eyebolt
and compressible hood design, are used depending upon the
current rating and conductor size of the cable. Eyebolt style
lugs will accept up to a 250 kcmil overhead conductor. A flat
pad, clamp type and two styles of offset aerial lugs are available
for use with the hood constructed terminations. Standard hoods
are made of tinned aluminum with copper hoods available.
Various types of copper and aluminum aerial
lugs are available for hood style terminators. Copper lugs
are for use on copper aerial connections only. Aluminum lugs
are tin plated and can be used for both copper and aluminum
aerial connections. Flat pad and style 8 offset lugs are for
bus connections while clamp and style 4 offset lugs are for
bare wire aerial connections.
Brackets –
Various styles of pole, crossarm and channel mounting brackets
are available for single and three single conductor terminations. For more information see Bracket Selector Guide.
