CONNECTORS
INTRODUCTION
BURNDY®electrical connectors are
designed to be installed with a minimum of
effort, to run cooler than the conductors
being joined and to provide optimum per-
formance under all operating conditions.
To achieve this type of performance, exten-
sive research and development time is spent
by BURNDY®engineers and scientists to
improve manufacturing techniques, materials
and designs. As these improvements become
available, they are incorporated into both
existing and new product lines. This continu-
ous program of product innovation and
improvement insures that, as new and more
critical applications evolve, high quality con-
nectors from BURNDY®will be available to
meet the need.
Flat pad connectors used to join cable or
tubing terminals to equipment studs.
A variety of bus supports are also available
for tube or cable. Some can be adjusted for
either a rigid or slide-fit by rotating the
clamping cap 180°.
Expansion connectors are used to absorb
the stress imposed on the bus by settling
ground, thermal expansion and shocks, as in
circuit breaker operations. The flexible ele-
ments are flat-tinned, copper braid, with suf-
ficient cross sectional area to carry the rated
current of the conductors being joined.
N-Line connectors are two-piece copper
alloy castings assembled with DURIUM™
(silicon bronze) hex bolts, nuts and washers.
They are available for connecting tube or
cable.
The Variline incorporates a modified V-bolt as
the clamping element for heavy-duty appli-
cations. This line is particularly suited for use
with flexible and extra flexible cables.

FLEXIBLE COPPER
BRAID JUMPER
Copper braid is made of tinned, pure copper
wire woven and flattened into a rectangular
shape for greater flexibility. Seamless, pure
copper ferrules are formed and assembled
on each end to provide appropriate
contact surfaces.
Braid is used extensively to compensate for
expansion and contraction of moving parts
and for thermal movement of rigid devices;
to prevent breakage of insulators or bushings
or equipment because of misalignment dur-
ing settling of substation foundations; to
absorb shock and vibration of operating
equipment; and to provide flexible current
carrying leads between moving parts of
heavy machinery or equipment.
CURRENT CARRYING
CAPACITY
Flexible copper braid has generally better
heat dissipation properties than flat bar,
cable or other conductors, and therefore can
be expected to have a greater current carry-
ing capacity for a given cross-sectional area.
This is due to its greater surface area result-
ing from the woven construction of fine
strands. However, ventilation, due to the ver-
tical convection current of air, is appreciably
better when the long axis of the braid is ver-
tical rather than horizontal, so that the long
sides of the braid, rather than the edges, are
exposed to the moving air. This is particular-
ly true when spaced braids are used in
multiple as can be seen by comparing
Figures 1 and 2.
To take full advantage of ventilation, the
cooling convection current of air should be
permitted to flow freely between the braids.
Therefore, if possible, the braids should be
spaced apart, rather than bunched together,
as illustrated in Figure 3. The effectiveness of
spacing is, or course, greater when the
braids are in a vertical position.
BULK BRAID
Bulk braid can be ordered with a minimum
order quantity of 10 feet. Specify feet in num-
ber of inches.

COPPER BRAID
CUSTOM DESIGNS
Flexible copper braid offers an economical
and efficient means of protecting electrical
equipment from the potentially harmful
effects of shock and vibration, terminal
expansion, movement of components and
misalignment that may occur during the
service life of the equipment.
Many varieties of braid are required to meet
those needs which we can build to your
specifications.
We also offer engineering assistance in the
selection of the most appropriate standard
or custom braid configuration for your
application.

CONNECTORS FOR
ALUMINUM CONDUCTORS
Bolted aluminum connectors are cast of alu-
minum alloy and assembled with aluminum
alloy bolts, nuts and galvanized steel
washers. The hex head bolts are captured for
one-wrench installation. The connectors
accommodate aluminum or copper conduc-
tor. The “mass anode” design pioneered by
BURNDY®minimizes the effect of galvanic
corrosion on aluminum (anode+) connectors
when used with copper (cathode –) conduc-
tor (Reference Fig. 1).
Joint deterioration caused by relaxation or
“cold flow” of the aluminum is eliminated by
the massive design. Generous contact areas
distribute clamping forces evenly over the
conductor, eliminating points of high stress
that cause “cold flow.” These contact areas
are factory treated to remove surface oxides
and coated with an oxide inhibitor to prevent
their reformation. Large radiating surfaces
allow the connectors to run cooler than the
copper conductor compensating for the fact
that aluminum has a higher coefficient of
thermal expansion. Connector and conduc-
tor expand and contract together during load
cycles, eliminating stresses on the aluminum
body that can cause relaxation of the joint.
CONNECTOR SELECTION
Generally, copper connectors are recom-
mended for copper conductor and aluminum
connectors for aluminum conductor. Where
aluminum connectors are recommended for
use on both aluminum and copper conduc-
tors, the copper must be positioned parallel
to or below the aluminum to prevent contam-
ination of the aluminum by copper salts
washed down by rain.
Except where indicated, all rigid connectors
accept standard or extra heavy I.P.S. and all
flexible connectors standard I.P.S. If extra
heavy I.P.S. is to be used with a flexible joint,
it must be spelled out at the time of ordering
so that the proper cross sectional area of the
flexible element may be supplied for the
increased conductor rating.
CONDUCTOR PREPARATION
To obtain optimum performance from any
connector, the conductor surface must be
thoroughly cleaned before installation. The
surface oxides that form on all conductors
act as insulation. Failure to remove them
can result in high resistance joint and, ulti-
mately, failure.
Conductor contact surfaces should be
scratch brushed until bright and shiny.
Aluminum conductor (new or old) should be
coated with BURNDY®PENETROX™ after
scratch brushing. PENETROX™ is a joint
compound that aids in the establishment of
low resistance joints and prevents aluminum
oxides from reforming.
