Global Telecom recently said, the submarine communication cable construction at a cost of $ 250 million which will directly connect Southeast Asia and the United States has officially started construction recently.

China has thousands of wire and cable manufacturers, and the quality has different levels. For the majority of users, the selection of high-quality products from a number of wire and cable brands is very complex. Collecting these five tips from the network to identify the quality of wire and cable,   it will help the majority of users make the decision.

The First, observe with eyes
You need observe and check three points: the quality system certification; the name, address, test chapter, and the production date; the printed trademark, size, voltage, and details on the wires.

The Second, test with hands
You can pick up a piece of wire and repeatedly bend its head, if it is soft, fatigue strength, elastic plastic or rubber handle and no cracks on the wire insulation, it is exactly the superior product.

The Third, distinguish copper
Usually qualified copper wire should be purple, shiny, soft touch. But the inferior copper wire is shoddy purple, yellow or white, impurities, poor mechanical strength, poor toughness, that would be a little harder to break, often worse in the wire breakage phenomenon. While in inspection, as long as one end of the wire stripped 2cm, then a piece of paper with a little twist on the copper, if there is a black substance on white paper, indicating existing more copper impurities .

The Fourth, weighing
Good quality wire, generally within the specified weight range. Here are several sets of data, for your reference.
Under normal circumstances, the commonly used cross-sectional area of 1.5mm2 single strand of plastic insulated copper wire, each weighing 100m 1.8-1.9kg; and 2.5mm2 single strand of plastic insulated copper wire, each weighing 100m 3-3.1kg; 4.0mm2 single strand of plastic insulated copper wire, each weighing 100m 4.4-4.6kg. So, poor quality or insufficient wire weight, or not long enough, or is too much copper wire impurities.

The Fifth, comparing the price
Due to the low production costs of fake wire, when in the sales, they often under the guise of cheap low-cost sales and lure people fooled. Therefore, you can’t pick the wire and cable product without the price consideration.
