BRAIDED FLEXIBLE
HIGH FLEXIBLE AIR COOLED COPPER CONNECTORS
Highly flexible connectors are manufactured from braided tapes/ropes/cables with bare, tin or silver coated
copper wires of diameter of 0.07/0.30 mm.
Standard flexibles are non insulated but on request it is possible to deliver the connectors with insulation
tubes. The contact areas are assembled with solderless pressed bare, tin or silver coated copper connectors
The advantage of the solderless pressing process is that only material of same analysis and same conductivity
is being connected which is not the case where tin or welding is additionally used.

Flexible connectors are manufactured by Copper or Aluminium strips.
They consist of several stacked strips with rivited or welded contact
areas. They have a constant corss-section over the whole length.
Busbars and laminated connectors witht he same corss-section can
be loaded with the same current. To manufacture suitable connectors
for the variable applications we have different methods of production.
So we manufacture connectors in various types.

at copper and aluminium joints.
WHAT IS COPAL?
COPAL consists of copper (sheet metal) claded on pure Aluminium
(base metal), both metals being diffused together to form an
inseparable whole by roll bonding process.
COPAL, is therefore not an alloy and the copper layers are not Electro
plating but are rather mechanically welded to Aluminium sheets.
WHY COPAL?
It is known that when Aluminium Terminals are directly connected
to Copper Terminals to carry current at a high voltage, a bimetallic
galvanic corrosion occurs, resulting in a high resistance at the joint.
The heated joints are oxidised and looses contacts resulting in sparks,
voltage dropout power losses and failure, damages to machinery.
When COPAL bimetal is placed between Aluminium Terminal and
Copper Terminal at the joint (with Copper facing Copper and
Aluminium facing Aluminium), bimetallic galvanic corrosion is averted
due to absence of air in COPAL bimetal. COPAL is thus used at
dissimilar metals joints of Aluminium and Copper to make similar
metals contact.
COPAL has been successfully evaluated and used by many of the
world's leading electrical equipment manufacturers.
