Lampholders for Discharge Lamps
THERMOPLASTICS
AND PORCELAIN
THE RIGHT MATERIAL MIX
SPELLS A DECISIVE ADVANTAGE
The lampholders presented in this chapter are designed for highpressure
discharge lamps, for which high ignition voltages and high
starting currents are characteristic. High temperatures can also occur
with higher lamp outputs.
Vossloh-Schwabe therefore attaches great importance to ensuring
casings, contacts and cables are made of high-grade materials.
Owing to the high ignition voltages, these lampholders are also
governed by stricter requirements regarding creepage and air
clearance distances.
When operating high-pressure discharge lamps with E27 and E40
Edison bases, care must be taken to ensure that the respective
lampholders are approved for use with discharge lamps. Lampholders
that are suitable in this respect are marked with "5 kV".
Lampholders with E26 and E39 bases and UL-approved wiring can
be found under www.unvlt.com.
