Wire and cable is already an essential material in electricity, and many home lines are to listen to the advice of electricians or to consult sales staff for purchase. If we know something about it, we can be more confident when choosing a route. So how to see the quality of wire and cable and how to choose?

Today, I will understand with you: identify the quality of wire and cable.

1) First of all, the quality of the wire and cable is good or bad to see whether it is within the specified weight range. The general weight of poor quality is insufficient, either because the length is not enough, or the impurity of the wire copper core is more.

2) Secondly, the wire and cable to see the manufacturer. Generally, fake and shoddy products have no manufacturer, no production date, no quality assurance, but there are also ambiguous signs of origin above, such as made in China, a province or a city in China, which is actually equivalent to the unmarked origin.

3) Again, the wire and cable look at the copper core of the wire and cable. The copper core is purplish black, yellow or white, many impurities, poor mechanical strength, poor toughness, a little force will break, and the wire is often broken.

4) Then, look at the price of wire and cable. Generally, fake and shoddy products have low production costs and poor material quality, and people are deceived under the guise of cheap and high-quality products.

Wire and cable selection method

There are often the following kinds of insulated wires: PVC insulated wires, PVC insulated cords, nitrile polyvinyl chloride mixture insulated cords, rubber insulated wires, agricultural underground directly buried aluminum core plastic insulated wires, rubber insulated cotton yarn textile flexible wires, PVC insulated nylon sheathed wires, power and lighting PVC insulated cords. Select wire and cable manufacturers according to the use environment.

1. The selection of power cables should follow the following principles:

(1) The rated voltage of the cable should be greater than or equal to the rated voltage of the power supply system at the installation point;

(2) The continuous allowable current of the cable should be equal to or greater than the continuous current of the power supply load;

(3) The core section should meet the stability requirements of the power supply system when it is short circuited;

(4) Check whether the voltage drop meets the requirements according to the cable length;

(5) The minimum short-circuit current at the end of the line should enable the reliable operation of the protection device.

When purchasing wire and cable, specifications and quality are two points to pay attention to. Be sure to choose according to the actual situation, can not blindly listen to a specifications of the wire better not to covet cheap, because it is easy to buy inferior products. The quality of the wire is directly related to the safety of the household electricity. The most correct choice is to choose the genuine wire that suits your home.
