How do power cable manufacturers choose suitable household wires cables?

In the home decoration, many friends in the choice of wires to save money, often think that wires do need to be too expensive, the general can, in fact, this idea is wrong. Wire is related to the problem of household electricity, because wire is generally installed in the wall, once there is a quality problem to repair, it will bring some trouble to repair. So, what should we pay attention to in the selection use of home installed wires? Below, the power cable manufacturers to understand it!

1、 Identify the "CCC" certification mark.

Because of its close relationship with the life of consumers, the quality safety of products directly affect the personal property safety of consumers. Therefore, wire cable products are products with national compulsory safety certification. All production enterprises must obtain "CCC" certification CNEEC, obtain "CCC" certification mark, have "CCC" certification mark on the certificate product.

2、 Insulation. The uniformity of wire insulation layer shall be thin the average thickness shall be specified in the national standard. The thickness of normal wire insulation layer shall be uniform, deviated the core, tightly wrapped on the conductor.

3、 Core. The core is made of pure copper raw material is strictly drawn, annealed (softened) twisted. Its surface should be bright, smooth, burr free, stranding tightness flat, soft ductile, easy to fracture. You can ask the merchant to cut off the head see the copper core material.

4、 The appearance of the product is smooth, round even in color. In order to improve the quality of products ensure that the products meet the requirements of national standards, we should strictly control the purchase of raw materials, production equipment, production process, etc. Therefore, the appearance of the wire cable products meet the standard requirements: smooth round, even color. 5、 The conductor is glossy, DC resistance, conductor structure size, etc. meet the requirements of national standards. The products of wires cables that meet the requirements of national standards, whether aluminum copper, are bright oil-free. Therefore, the DC resistance of the conductor completely meets the national standards, with good conductivity high safety.

5、 The conductor is glossy, DC resistance, conductor structure size, etc. meet the requirements of national standards. The products of wires cables that meet the requirements of national standards, whether aluminum copper, are bright oil-free, so the DC resistance of the conductor completely meets the requirements of the country.
