Causes and preventive measures for wire and cable damage in winter
Causes and preventive measures for wire and cable damage in winter
In the winter, many construction workers will find that wire and cable products with good quality often have some hard lines and damaged insulation skin. Many construction workers think that it is the wire and cable product itself. There have been quality problems, and cable manufacturers have insisted that the products have been tested at the factory and...

Advantages of aluminum alloy cables
Advantages of aluminum alloy cables
Conductive properties: The electrical conductivity of aluminum alloy is 61.5% of the most commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, which is superior to the pure aluminum standard.2. Creep resistance: The alloy material and annealing treatment of aluminum alloy conductors reduce the "creep" ten...

The difference between high temperature control cable and power cable
The difference between high temperature control cable and power cable
The power cable is the backbone of the power system to transmit and distribute large functional power. The rated voltage is generally 0.6/1KV and above. The high temperature control cable is used to directly transfer electrical energy to various power equipment and its rated voltage is 450/750V. This makes the insulation and sheath thickness of the power...

How to lay power cable lines
How to lay power cable lines
(1) Directly buried in the ground, this is the most common and economical method of laying.(2) Laying in the cable trench for laying multiple cables.Although the cable ditch was larger than the direct burial at the time, it was convenient for temperature monitoring and ventilation and cooling measures to improve its heat dissipation conditions. In addit...

Rare accidents with overhead wires suggesting 10kV overhead lines
Rare accidents with overhead wires suggesting 10kV overhead lines
There are many kinds of lightning strikes on 10kV overhead lines, such as breakdown or burst of insulators, disconnection, and distribution transformer burning. Lightning strike accidents, of course, have a great relationship with the objective reasons of lightning strikes, but also have a great relationship with equipment defects. The reasons for t...

The methods to ensure the quality of control cable
The methods to ensure the quality of control cable
The appearance quality of the cable is very important. The first impression given to the user is the appearance quality of the product. Therefore, all good products pay attention to the appearance quality. For example, flame-retardant shielded control cables, low-smoke halogen-free control cables, and xlpe insulated control cables. For the appearan...

Main factors affecting the overall tensile properties of overhead conductors
Main factors affecting the overall tensile properties of overhead conductors
The extra breaking force of the wire is calculated from the strength of all aluminum single wires and reinforcements. However, the actual breaking force will have a certain bias with the actual calculated value. The secondary reason is that the strength of each single line has not been lost. Therefore, when designing a product, you should not only meet the m...

Aluminum alloy core aluminum stranded wire overall performance improvement skills
Aluminum alloy core aluminum stranded wire overall performance improvement skills
The rated breaking force of the wire is calculated from the strength of all aluminum single wires and reinforcements. However, the actual breaking force will be deviated from the actual calculated value. The main reason is that the strength of each single wire is not fully utilized. Therefore, when designing the product, not only must meet the minimum stre...

Method for treating power cable moisture
Method for treating power cable moisture
In the long-term construction process, we found that the phenomenon that the cable is damp and influence has become a potential hidden danger affecting the safe operation of the cable.1. Causes and hazards of cable flooding(1) When the new whole cable is shipped from the factory, both ends are sealed with plastic sealing sleeves. However, after the constr...
