What are the advantages of copper core cables compared to aluminum core cables?
Copper and aluminum are both used as conductor materials in wire and cable products. Why are copper core cables more widely used than aluminum core cables? What are the advantages of these two cables compared to copper core cables? Next, let me explain the differences between copper core cables and aluminum core cables, and what advantages aluminum core cables have compared to copper core cables.

Development history of power cables
Power cables are cables used for transmitting and distributing electrical energy. They are commonly used in urban underground power grids, power plant outgoing lines, internal power supply of industrial and mining enterprises, and cross-river and underwater power transmission lines.

Let me explain several reasons for the aging of power cables.
Let me explain several reasons for the aging of power cables. Water ingress can easily affect the normal use of power cables. First, we must recognize the harm of water ingress. Generally speaking, after water intrusion, under the action of the electromagnetic field, the phenomenon of "water tree aging" will occur. After the water tree is formed, the electric field at the water tree formation site is easy to change, reducing the insulation performance of the cable. When it can conduct electricity, the cable will be broken down, seriously affecting the stability of power supply.

Let me explain the reasons for power cable heating and the difference between flame-retardant and fire-resistant cables. Reasons for power cable heating When a certain load current passes through the power cable, it will generate heat. As the load current increases, the surface temperature of the cable will be higher. Therefore, the reasons for power cable heating and how to choose power cables are discussed.

Below is a discussion on how to identify inferior power cables
Below is a discussion on how to identify inferior power cables. How to identify inferior power cables? Counterfeit products are not uncommon in the market. Even in the power cable industry, there are some inferior products mixed in, which seriously affects our power safety and has long-term hidden dangers for our lives. If fake power cables are used, it may cause short circuits and electric shocks in minor cases, and fires and casualties in serious cases. In recent years, more than 40% of fires have been caused by electrical faults, and copper core "shrinkage" black core power cables are one of the main reasons.

Distinguishing between wires and cables
Distinguishing between wires and cables Wires can consist of one or more flexible wires covered with a soft covering; cables consist of one or more different insulated wires covered with a tough metal or rubber outer layer. Generally, the difference between cables and wires in enterprises is that they are composed of three main parts: core wires, insulation, and protective outer sheath.

Main categories of wire and cable products
The design of wire and cable products can be mainly divided into five categories: 1. Bare wire and bare conductor products The main development characteristics of this type of information product are: pure conductors are made of metal, without insulation and sheath, such as steel core aluminum stranded wire, copper aluminum busbar, electric locomotive wire, etc.; the processing technology is mainly through pressure processing, such as melting, rolling, drawing, twisting/tight twisting, etc. The product design can be mainly used for suburban areas, rural areas, user management trunk lines, switch cabinets, etc.

Types and characteristics of mineral-insulated cables, explained by a wire manufacturer
Wire manufacturers believe that with the increase in high-rise buildings, rescue during fires in high-rise buildings is becoming increasingly important. In order to ensure a certain power supply time for rescue after a building fire, higher requirements are put forward for the building's power supply facilities, especially the ability of cables to maintain continuous and safe power supply under fire conditions. Wire manufacturers believe that mineral-insulated fire-resistant cables for fire systems are the guarantee for achieving this goal. Mineral-insulated cables, commonly known as fire-resistant cables, are made of mineral-insulated all-inorganic materials and have the characteristics of high temperature resistance, radiation resistance, corrosion resistance, and high mechanical strength. The operating temperature can reach 1000. It can not only be used in fire environments

Some knowledge points about mineral cables, told by wire manufacturers
Wire manufacturers believe that mineral-insulated cables are the main fire-resistant cables that ensure power transmission in modern construction projects, suitable for power supply lines such as fire power supply, uninterrupted power supply, and emergency lighting power supply. Most high-rise buildings on the market need mineral-insulated cables, and the market application is very mature. Wire manufacturers believe that the characteristics of mineral-insulated cables are as follows: 1. High operating temperature: Wire manufacturers believe that mineral-insulated cables can withstand continuous operating temperatures as high as 250. However, in emergencies, the cable can continue to operate for a short time at temperatures close to the melting point of the copper sheath;

Some common sense about mineral cables, explained by a wire manufacturer
Wire manufacturers believe that mineral-insulated cables are the main fire-resistant cables that ensure power transmission in modern building projects, suitable for power supply lines such as fire protection power supply, uninterruptible power supply, and emergency lighting power supply. Wire manufacturers believe that mineral-insulated cables are composed of copper cores, mineral insulation materials, and copper metal sheaths. They not only have good conductivity, mechanical and physical properties, and fire resistance, but also good incombustibility. Under fire conditions, this type of cable can ensure the use of electricity for fire protection during the fire, and will not delay the fire or produce smoke. Therefore, the specifications allow this type of cable to be directly exposed.
