Vacuum Interrupter VS30029

About product:
Features:
Advanced and reliable working process (ensured
vacuum tightness), 100% imported raw materials
(Copper-Chromium 50 contact material support to resist wear away), long life time metal
bellows -- to ensure 30,000 operating time of vacuum interrupters.
-The contact in the vacuum are not subject to impurities or contamination on their surface.
And due to special treatment the contacts have good surface quality and high conductivity.
All these features have contributed to a low inside resistance of the interrupters in the
range from 8 to 15􁪽̦􁪽, the result is low temperature rise during the long operation of the
interrupters.
-Excellent design, 100% imported raw material and advanced working process to make the
components surface clean and smooth so that to reach high dielectric strength which in
line with IEC and GB
-Thanks to the introduction of one-shot brazing technology it is possible to achieve reliable
brazing jointing. And the brazing seam is not vulnerable to ageing deterioration
Interrupters brazed with such technology have by far lower leakage than those brazed with
conventional technology. High vacuum tightness is therefore ensured over the entire life
span of the vacuum interrupters.
