Answers to hot questions about copper bar products

Many people have some questions about copper bar, tinned copper bar and grounding copper bar. Here, Buck Copper answers the hot issues that we are concerned about.

1. What are the classification of copper bars?

In fact, many classification standards of copper bar lead to more specific classification, such as according to the material classification can be divided into T2 copper bar and T3 copper bar; According to the use can be divided into grounding copper bar and distribution box copper bar; According to the surface treatment can be divided into tinned copper row and red copper row and so on.

2. How to choose the specification of copper bar?

Many users in the purchase of copper bar products for the selection of special specifications headache, buy large specifications for fear of unnecessary waste, but buy small specifications and fear not enough to bury the hidden safety risks, here by copper bar manufacturers in copper copper industry to introduce how to choose specifications of copper bar products, In fact, we choose specifications mainly according to the load size to compare the bus load meter to make a reasonable choice, the specific selection of specifications can refer to the following two points:

A, rated current, the selection and use of copper bar must be able to meet the demand (the rated current value can be calculated through the load capacity);

B. Short-time tolerated current, which means that the type of copper bar we choose should be able to meet the use demand of short-time high-flow current in the line.

When selecting the type, we need the maximum value of rated current and short-time tolerated current to make a correct choice against the bus current table.

3. Why do copper bar prices fluctuate and differ?

For example, many users responded that the copper row I bought last time was only 50 yuan, why is it 55 yuan this time? In fact, there are many factors affecting the price of copper bar. Buck copper industry will briefly introduce why its price will be different and different?

A, the more you buy, the lower the price, the amount of copper platoon in general user one-time buy more manufacturers to offer would be the lower (in order to retain customers select the meager profit but high turnover), for buying fewer customers are generally the retail price (A little) A little higher than the wholesale price of its copper platoon, so I strongly recommend everyone according to his demand for copper platoon as far as possible one-time buy more;

B, different materials lead to different prices. We all know the difference between T1, T2 and T3 common copper bar products. Generally speaking, we choose to use T2 copper bar (cost-effective).

4. How much is the error of copper bar size?

In particular, some people who buy copper products for the first time find that there is error in size and I want with a caliper after buying copper products, then do you know the reasonable error of copper products is generally within the range of more words? Is a standard of the specifications of the copper platoon size 10 * 200 (mm), if you need 20 * 20 (mm) of the copper platoon manufacturers would be to cut the standard copper platoon, although the copper platoon error of cutting technology is more mature can still exist, such as copper for non-standard size copper platoon cut the Buck to ensure that the error between 1 to 3 mm, Therefore, it is recommended that you choose copper bar manufacturers with high accuracy and small error to buy more reliable.
