LEAD - IN - WIRES
|
LEAD-IN-WIRES are one the most
important component and forms a nucleus in manufacture of Lamps
and Picture Tubes since it conducts electricity to the filament
and acts as sealing component from glass to metal. It also provides
resistance upto specified requirements. Based on individual applications
the specifications are selected by the Lamp manufacturers.
The major applications of Lead-in-wires
are …

However, the standard specification
of Lead-in-wires widely used by Lamp Industries are as mentioned
in Table A . Any other specifications, dimensions or materials combination
can also be available on request.
The Lead-in-wires are available in
Electric Welding or Gas Welding.
