All things considered, they all utilization high-virtue tungsten contacts
, chiefly on the grounds that the contacts have a high liquefying point, a sluggish dissipation rate, and great electrical and warm conductivity. Contrasted and customary contacts, the contacts made of metal tungsten have a more extended cycle life and simultaneously guarantee great contact of the circuit board.
As of now, normal control electrical items, for example, AC contactors, electromagnetic transfers, electrical switches, and air switches all contain electrical endlessly contacts are one of the main parts of these items.
The dependability and administration life of the item depends generally on the contact execution, and the contact execution is impacted by elements, for example, contact material, load type, contact pressure, working recurrence, and use climate. At the point when these variables can't meet the functioning necessities, issues, for example, electrochemical erosion of contacts, welding between contacts, contact wear, and increment of contact obstruction will happen, which will prompt questionable activity, useful disappointment, and, surprisingly, potential wellbeing risks.
In the empowered state, on the off chance that the ongoing that opens the circuit surpasses a specific cutoff, or on the other hand assuming the voltage on the contact hole surpasses a specific breaking point after the opening, the contact hole will show up. Under the activity of a solid electric field, the gas between the contacts will release. Flashes areas of strength for and will be created and radiated with the increment of the temperature. The circular segment will erode the metal surface of the contact, abbreviate the assistance life of the electrical machine, expand the breaking season of the circuit, and cause the contact disappointment of the contact. In extreme cases, it can likewise cause fire mishaps.
These days, to additionally work on the general nature of electrical gear contact focuses, most producers utilize metal tungsten to make electrical contacts.
