Causes of common problems of high-voltage cables
Cable is a bridge between power supply equipment and power use equipment, and plays a role in transmitting power. Due to its wide application, failures often occur. This paper briefly analyzes the causes of common problems of YJV high-voltage cables. According to the classification of the causes of failures, it can be divided into four categories: manufacturing reasons of manufacturers, construction quality reasons, design reasons of design units and external force damage. Then, let's understand the causes of common problems of high-voltage cables together!

Cause Analysis of Abnormal Grounding Circulation of High Voltage Cable
The cable above 10 kV adopts single-core structure, and the metal protective layer produces grounding circulation. If the circulating current exceeds the standard (the circulating current value is above 50A or 20% of the load current or the maximum/minimum value between phases is above 3), it will not only affect the current carrying capacity and service life of the cable, but also the alternating magnetic field generated by the working current will generate induced potential in the metal protective layer. If the sheath passes through the earth to form a channel, it may also cause malignant power grid accidents. Serious heating caused by circulating current will also burn the grounding wire or grounding, let's understand the cause analysis of the abnormal grounding circulation of the lower high-voltage cable!

How to distinguish the difference between low voltage cable and medium and high voltage cable
There are many types of cables. The most basic ones are low-voltage cables and high-voltage cables. How should the two be distinguished? Some people say 250V, some people say 1000V, how to distinguish between high-voltage and low-voltage? So, let's learn how to distinguish between low-voltage cables and medium-and high-voltage cables!

Installation of High Voltage Cable
When installing 6kV or 10kV electrical equipment, we will encounter situations where a single-core short cable is required as a connecting line. In electrical engineering installations, three-core high-voltage cables are sometimes used. Strip the outer skin, strip the ladle armor, and use the three-core wire as a single-core cable. Even if the insulation resistance of the single-core cable meets the requirements, if the core is installed close to the external metal parts, the discharge of structural parts will occur, especially in the wet weather in spring, which will endanger the safety of equipment and personnel.

Basic structure of power cable
The third side of the power cable power supply is the core (conductor). The outer side of the core is phase insulation and filler, and the outer side is three-phase blanket insulation. The insulation layer of the package is covered with a lead package, and the outer layer of the lead package is a protective layer such as steel armor and PVC sheath.

Causes of power cable moisture
We have sorted out the following for everyone: when the power cable is in normal operation, if it fails for some reason, the water in the cable trench will enter the cable along the fault point; in civil buildings, especially in the use of large construction machinery construction sites, cable breakage or breakdown accidents caused by various human factors are not uncommon. When such an accident occurs, the insulation of the power cable is seriously damaged, which will also cause the cable to enter water. After the power cable laying is completed, due to the limitation of the application conditions on site, the cable head cannot be made in time, resulting in the unsealed cable fracture being exposed to the air for a long time or even immersed in water.

Construction and manufacture of high voltage cables
The reasons of high-voltage cable manufacturers can be divided into three categories according to different locations: cable body reasons, cable joint reasons, and cable grounding system reasons. Cable body manufacturing reasons. The problems that are prone to occur in the general cable production process are: insulation eccentricity, uneven thickness of insulation shielding layer, impurities in insulation, protruding internal and external shielding layer, uneven crosslinking, cable moisture, poor sealing of cable metal sheath, etc. Some cases are more serious and may fail soon after the completion test or operation. Most of them exist in the form of cable system defects, causing serious hidden dangers to the long-term safe operation of the cable.

What is the difference between high voltage cable and low voltage cable
Cables are used to transmit power, but the cables sold on the market are divided into high-voltage cables and low-voltage cables. There are many differences between these two types of cables, and their application ranges are not the same. High-voltage cables are an important member of power cables. He is used to transmit power between 1kv and 100kv, low-voltage cables are used to transmit power below 1kv, which is the most important difference between the two.

How can we find regular overhead insulated wire manufacturers?
In the past, many users are looking for overhead insulated wire manufacturers to find it, but do you know if they have their own factories? Have you ever understood their strength? If you don't understand these, then you still have risks if you want long-term cooperation. So, how can we find the formal overhead insulated wire manufacturers? On this issue, we will introduce for everyone.
