One, choose according to wire

The longest and most critical part of the data line is the wire. Wire is formed by the shielding layer of the inner core inside, center and outside, every part is worth us in a way consider.

1, the inner core

(1) Raw materials

Data lines on the market are mainly copper wire, iron core cross copper, iron core galvanized and iron core, copper wire charging speed is the fastest and iron core is the slowest, advocate the choice of copper core charging line. It can pass the maximum 2A current in the process of current transmission, and does not simply present the risk of heating, so it is the ideal inner core material.

(2) Quantity

"Charging for five minutes, talking for two hours" is the demand of many people, and the number of inner cores can accelerate the charging speed accordingly. There is a line of 8 core, 10 core, 12 core optional core on the market now, the more the number of charging faster, the price also rises accordingly. Can be combined with charging speed and price on demand.

2. Shielding layer

The shielding layer is wrapped with a layer of aluminum foil or metal woven net outside the inner core, which can prevent current channeling and short circuit and other risks. On the market, there is a single use of one or two kinds of shielding layer, which can better ensure the charging effect and the price will be more expensive.

3, was outside

The outer cover is the outermost layer of the data line, and its hardness, strength, elasticity and other properties directly affect the operation feeling. Now there are mainly PVC, TPU and preparation line three kinds of outer quilt, each has excellent defects, need to choose according to love.

1) PVC raw materials

Polyvinyl chloride, PVC for short, is a relatively cheap polymer chemical material, due to the increase of many additives in the process of artificial synthesis, so the early use of relatively heavy taste. Surface lubrication but more hard, not too resistant to folding.

Advantages: smooth appearance, smooth touch

Defects: when just received, there is a peculiar smell, but also simply show the skin, broken condition. Do not advocate the choice of such outer quilt.

(2) TPE raw materials

TPE is a kind of thermoplastic elastomer data, thermoplastic, elasticity, weakness is very good, more than the PVC data non-toxic tasteless characteristics. Many original lines are also this raw material, it can be said that data lines basically need such raw materials.

Advantages: good thermoplastic, soft touch, high softness, non-toxic and tasteless, not simply broken.

Defects: the service life is not long, simply showing the skin, yellow condition.

(3) Weaving thread

The weaving thread is generally made of nylon, and a layer of nylon is wrapped on the outside of TPE. Wear resistance and tensile ability are significantly strengthened, and compared with PVC and TPE raw materials are significantly more anti-fouling, service life is increased.

Advantages: long service life, anti stain, anti pull, anti break can be relatively strong. Because it is not made of plastic, it is not simple to show the phenomenon of broken winding.

Defects: Due to the addition of an outer layer, if the core selection is not good, it simply presents the phenomenon of charging and heating, which is relatively risky.
