The structural components of wire and cable products can generally be divided into four main structural components of wire, insulation layer, shielding and protective layer, as well as filling components and tensile components. According to the requirements and applications of the product, some products have a very simple structure, with only one structure of wires, such as overhead bare wires, catenary wires, copper-aluminum busbars (bus bars), etc.; the external electrical insulation of these products depends on installation and laying Use insulators and space distance (that is, use air insulation) to ensure.

We TANO CABLE are professional power cable manufacturer in China, we have a new shipment of Blue Power Cables to Yemen

The ABC, known as the NFC 33209 aerial bundled cable is manufactured and designed for fixed installations for overhead-power lines with a maximum of 1000V incl. These cables are also used to supply 120/220V aerial services for term services on construction sites, in the form of a service-drop which involves power-pole to a service-entrance, in the form of a secondary-cable which involves pole-to-pole, or for street lighting requirements. For services that reach a maximum of 1000V or lower, the cables are able to handle a maximum conductor-temperature of 90 degrees Celsius. 

Let us understand that the shielding layer mainly plays a role in resisting external electromagnetic interference, preventing the electromagnetic field generated by itself from interfering with the surrounding environment and passing fault current during use.

Santiago, September 1 (Reuters)-Chile's mining minister told Reuters on Wednesday that Chile needs US$150 billion in investment to achieve its goal of nearly doubling copper production by 2050. This is also one of the world's largest copper-producing countries' plans to increase production while reducing environmental impact.

What is discharge?

Between two conductors with a potential difference, when the performance of the insulating material decreases, electron energy transfer occurs between the two conductors. For example, the ignition between the high-voltage live wire and the ground wire is discharge, and the complete discharge is the instant of discharge. A complete arc channel is formed between the electrodes.
