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.

5 Quality control:

we provide samples to customer for checking before production; we will not produce until the sample is approved; we will do the product inspection randomly in the process of production to detect the problem in time, we also will select random products to customers for checking according to customers requirements after the completion of the production before shipping.

For the products with high assembly requirements, we will ask customers to provide the assembly parts, to ensure that the products can be assembled ok before shipment.

6. Provide valuable pictures anytime:

provide clear pictures of Electrical silver Contact point samples to customers for checking before the shipment; provide pictures of products which is in the process of producing; provide the detail packaging pictures showing the quantity and packaging of each product clearly after the completion of producing.

7. Freight advantage:

many customers who cooperate with us for many years give feedback that the freight charges that we offered is much lower than the costs that the customers arrange the transportation by themselves, in general, the price can be cheaper by 30 percent to 50 percent, which help customers save shipping costs greatly.

8. Efficiency:

Our sales department communicates with customers by using a variety of online tools (Skype, MSN, Trademanager,Wechat,WhatsAPP ...), telephone, and e-mail, and adjusts the working hours according to customer time difference to keep in touch with customers and answer customer inquiries at any time, customers can use PAYPAL, western union and other online payment platform to pay a small amount of sample fee to shorten the sample production time.
