What are silver-tungsten alloy contacts?

    High-quality silver-tungsten alloy contacts are composite contacts made of silver or silver-aluminum alloy cables and copper wires through a special cold heading machine based on the basic principles of mechanical equipment physics. It is a vacuum circuit breaker, high-voltage switchgear , high-voltage isolation switch, the main component of the power switch of the grounding device, its performance immediately endangers the quality and service life of this high-voltage electrical appliance.

    Classification of electrical contacts

    1. Fixed contact: The electrical contact that is clamped with standard parts such as screws or iron buckles is called fixed contact. Fixed contact has no relative speed in the operation link.

    2. Separable contact: The electrical contact that can be separated in the operation link is called a separable contact, also known as a contact. The contacts of household appliances have always been in pairs. One of them is the static contact of the silver-tungsten alloy contact manufacturer, and the other is the moving contact. When the contacts are closed, they are generally clamped by torsion springs.

    3. Rolling and flipping contact: During the operation, the contacts can roll or flip with each other, but the electrical contact that cannot be separated is called rolling and flipping contact.

    Electrical Contact Features

    It has good silver-tungsten alloy contacts for sale, which are resistant to electrical damage, anti-welding, electrical conductivity and heat transfer, and small contact resistance. Because silver cadmium oxide is diffused in various parts, it can improve the strength of the material and improve the resistance to mechanical equipment. Abrasion. According to the short-circuit capacity, the anti-welding ability is good, and the electrical contact manufacturing technology is very harmful to its performance. The electrical contacts produced by the powder metallurgy process have good welding resistance and poor single corrosion resistance. The electrical contacts made by the air oxidation method of aluminum alloy have good resistance to point damage, but the drought resistance is slightly lower.

    Electrical Contact Efficacy

    As a key component in the equipment of medium and high voltage circuit breakers, electrical contacts play the function of breaking and shutting off, and are widely used in various high-voltage load switches, SF6 isolation switches, on-load tap power switches and their high-voltage switches. Volume high voltage isolating switch and grounding device power switch.

    Use of electrical contacts

    Electrical contacts are mainly used in automotive relays, contactors, air leakage switches, overcurrent protection power switches, motor protectors, small power switches, instrumentation equipment, electrical products, automotive electrical appliances (light switches, starters and other high-voltage load switches), Leakage circuit breaker, etc.
