1. First of all, what is hard wire and what is soft wire?
Hard wire: a single conductive solid metal wire with a diameter greater than 1 mm, and its hardness is higher than that of flexible wire.
Flexible cord: a conductor twisted by a plurality of conductive solid metal wires with a diameter of 1 mm or less.
2. What are their advantages and disadvantages?
Hard wire: low price, strong tensile strength, strong corrosion resistance, weak fatigue resistance and high waste recovery rate.
Flexible cord: high price, weak tensile strength, weak corrosion resistance, strong fatigue resistance and low waste recovery rate.
In fact, in general, hard wiring will be better. Generally, each copper wire of the soft wire of the burning joint is too thin, which is easy to be damaged and oxidized, and the power distribution and heat conduction are uneven, which easily leads to copper wire burning. Therefore, the durability of hard wire is still relatively good, and it is simple, cheap and quick to install.
Moreover, at present, because the soft wire is multi-wire metal, the production is complicated and the cost is high, and then the price has no obvious advantage, so the hard wire is better.
The advantages and disadvantages of soft wires and hard wires also determine their use functions and places. Generally, hard wires are used for burying walls and underground, and are used as main lines. Flexible cords are generally used for power connection wires of household appliances and equipment. There is no difference between the two, only who is suitable for which position. So you can choose hard wire or soft wire according to the location of decoration.
