General Information
Vitreous enamelled wirewound resistors are capable of
withstanding a higher dissipation size for size, than any other
protected type; this is attributable to the higher operating
temperature which the wire and enamel can withstand.
Vitreous enamel provides exceptionally good protection to the
wire element and is essentially impervious to moisture. The
resistors can safely be used in harsh environmental conditions.
The Welwyn range is based on thirteen sizes of tube, each of
which has a recommended maximum dissipation which limits
operating surface temperature to a maximum of 375°C.
The stability and high reliability of Welwyn tubular vitreous
resistors is a direct result of the best quality materials being
used in their construction.
High purity ceramic tubes have been matched with nickel
chromium resistance wires and specially formulated enamel to
ensure that the resistors can withstand repeated heat cycling
without damage.
Connections between the resistance element and end
terminations are welded; other connections are brazed.
Mounting devices are available which permit resistors to be
mounted by both ends or by one end. Single ended mounting
is recommended for applications which do not subject the
resistor to shock or vibration.
Ferrules and the F type mounting plug are anchored into the
tubes with high temperature adhesive.
Special requirements, for types or styles not described
in this brochure, will be considered for economic
quantities.
