Silver Bi-metal Contact Point Used For AC Contactors

Quick Detail:

Characteristics and Applications for AgCdO contact material

Contact Material in Huano:Type 3

AgCdO10,AgCdO20

AgCdO10,AgCdO20 Properties

CdO particles are finely distributed in Ag matrix. Under the action of arc, CdO decomposes and vaporizes, which cools down the contact surface,

so as to lower the arc energy and extinguish the arc. This material is of high welding resistance and electric wear resistance, low and stable contact resistance.

by increasing CdO content, the welding resistance of the material can be improved, but the contact resistance and temperature rise will also increase.

Main applications for AgCdO10,AgCdO20 contact material according to its properties:

Widely used to relays, contactors and AC/DC switches for medium or large current, circuit breakers for medium or small current; specially fit for AC contactors for medium or large current.

Delivery forms:

AgCdO alloy Wire,AgCdO alloy tips or AgCdO alloy rivet

What are electrical contacts?

The contact is also called a tip, point, finger, wedge, button or segment.A single or multi-pole electrical product that contains movable and stationary contacts,

often including screws, springs and possibly other hardware is called a kit or set.

A contact opens and closes

(makes and breaks) to engage or interrupt an electrical circuit. They are usually used for switches,

relays, contactors and motor starters etc.

An electrical contact is defined as the interface between the current-carrying members of electrical/

electronic devices that assure the continuity of electric circuit, and the unit containing the

interface. The current-carrying members in contact, often made of solids, are called contact

members or contact parts. The contact members connected to the positive and negative circuit

clamps are called the anode and cathode, respectively.

Electrical contacts provide electrical connection and often perform other functions. The

primary purpose of an electrical connection is to allow the uninterrupted passage of electrical

current across the contact interface. It is clear that this can only be achieved if a good metalto-

metal contact is established. The processes occurring in the contact zone are complex and not

fully explained within the limits of present knowledge. Although the nature of these processes may

differ, they are all governed by the same fundamental phenomena, the most important being the

degradation of the contacting interface and the associated changes in contact resistance, load,

temperature, and other parameters of a multipoint contact.
