Wires and circuits are hidden works, and even small hidden dangers may cause serious safety accidents. Therefore, before laying the line, we should make full preparations. For example, when choosing wires and cables, we need to determine the appropriate cable based on various considerations. There are too many types of wires and cables, how should we choose? The following Yunnan cable manufacturers will analyze for you.

1. Selection of wire and cable model

(1) When selecting wires and cables, consider the use, laying conditions and safety;

(2) According to different purposes: power cables, overhead insulated cables, control cables, etc. can be selected;

(3) According to different laying conditions, general plastic insulated cables, steel tape armored cables, steel wire armored cables, anti-corrosion cables, etc. can be selected;

(4) According to safety requirements, flame-retardant cables, low-smoke halogen-free cables, fire-resistant cables, etc. can be selected.

2. Selection of wire and cable specifications

(1) When determining the specifications of the wire and cable (conductor cross section), conditions such as heating, voltage loss, economic current density, and mechanical strength should be considered;

(2) Due to the large load current of the low-voltage power line, the section is generally selected according to the heating conditions, and then the voltage loss and mechanical strength are checked;

(3) Since the low-voltage lighting circuit requires a high voltage level, the cross-section can be selected according to the allowable voltage loss conditions, and then the heating conditions and mechanical strength can be checked;

(4) For high-voltage lines, first select the section according to the economic current density, and then check its heating conditions and allowable voltage loss.

The cable is usually a rope cable composed of several groups or groups of conductors (at least two in each group). Each set of conductors is insulated from each other, usually twisted around the center. The whole is covered with a highly insulating cover layer. Most of them are installed in the air or underground or underwater for telecommunications or power transmission.

Although there are many factors to consider when choosing cables from Yunnan cable manufacturers, one thing can never be ignored, that is, the quality of wires and cables. The quality of the wire and cable directly affects the normal operation of the circuit. Unqualified wires and cables not only affect the use, but also directly endanger our lives. Therefore, we must choose high-quality cables with quality assurance.

Nowadays, more and more manufacturers sell cables. If you want to make the cable work better, you will have a good advantage in professional safety. You must understand the quality standards of the various manufacturer brands and identify specific needs during practical application. Only in this way can we choose the right brand and the quality of natural use will be better?

First of all, don't blindly covet cheap. If you want the cable you buy to show the effect of use, you must ensure that the quality of the cable meets the standard, and the stability and functionality of the cable also need to meet industry requirements. The only way to ensure that you buy the cable, avoid all kinds of accidents. If the cheap cable you choose is of poor quality, naturally, various safety hazards will easily appear.

Secondly, it is necessary to know whether the manufacturer's brand has better public recognition, as well as the evaluation and reputation of other consumer customers, so as to determine whether the brand has a better advantage. As there are more and more cable brands and the characteristics of different brands are different, people will inevitably feel very tangled and confused when choosing. If they want to achieve a better standard of use, then it is necessary to comprehensively measure the reputation and evaluation of different brands.

In order to achieve better cable use effect, especially to ensure better safety, it is recommended to purchase cables from Yunnan cable manufacturers, and select the appropriate specifications and models based on actual needs to ensure better display of its functional characteristics. Since many manufacturers sell different models of cable cabinets and different price positioning, it is recommended that you conduct a detailed analysis according to the specific situation.
