COELME-EGIC
Our railway switcher range is designed to ensure the best performances and reliability, which are the result of our 60-year old experience in the field of high voltage.
VSV AC railway switcher
The VSV AC railway switcher is an outdoor switch specifically designed to meet the needs of railway electrification, for applications both in overhead lines (at catenary level) and in feeder substations.
The VSV is composed of a sealed enclosure filled with inert gas where a vacuum interrupter is located. This device is operated by an electromagnetic actuator which is connected to it without any outside mechanical transmission rods.
The VSV’s strengths are its versatility and weather resistance, which make its installation possible also in harsh environmental conditions, with no need for adjustments or final calibrations.
Its simplicity, compactness and robustness make it easy to be installed as well as able to operate regularly, in the years, under maintenance-free conditions.
Pursuant to the most recent environmental laws on the use of sulphur hexafluoride, the VSV uses nitrogen only to guarantee the dielectric features, thus avoiding emissions of burnt gases during operations.
Reliability and Maintenance
The VSV is designed to be maintenance-free. The use of a high-quality vacuum interrupter ensures the constancy of performance in time.
The use of stainless material (or made so thanks to proper protective coatings) in the manufacturing of
all components, the presence of an electromagnetic actuator and of few moving parts, the absence of external transmission rods ensure an excellent level of reliability of the VSV for many years of operation.
