XLPE cables are considered by XLPE cable manufacturers to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station outlets and internal power supply in industrial and mining enterprises. Power cables are cable products used for the transmission and distribution of high-power electrical energy in the main line of the power system, including various insulated power cables of 1-500 kV and above.
Armored power cable manufacturers remind everyone that the external total protective layer of wires and cables plays a very important protective role. Generally in the production process, manufacturers will use better materials for the overall protective layer. Armored power cable manufacturers: The reason why the price of the wire is different is that it has a certain relationship with the category. The types of cables include overhead cables and household cables, and the prices of different types vary greatly.
Armored power cable manufacturers believe that in the structural design, production and selection of power cables, electrical properties (including electrical conductivity, insulation and transmission characteristics, etc.), mechanical and physical properties, aging properties, compatibility between materials and other properties Materials with good properties (such as metal hardness, creep, non-flame resistance, radiation resistance of polymer materials, etc.) must be comprehensively considered according to the purpose of the product, the use requirements and the laying environment. This requires a thorough understanding of metallurgy, metalworking, electroplating, polymer materials, dielectric chemistry, electrical insulation, polymer rheology and heat transfer.
Aerial cables are overhead conductors with insulating layers and protective sheaths. They are special cables made by a production process similar to cross-linked cables. They are a new type of transmission between overhead conductors and underground cables. Aerial cables are single-core, which can be divided into hard aluminum wire structure, hard copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure and self-supporting three-core laminated structure (the wire core can be hard aluminum or hard copper wire). Its main features are high reliability of power supply, good power supply, convenient erection and maintenance, economical and reasonable. Its main technical parameters include weather resistance, insulation level, inner and outer semi-conductive shielding layers. Aerial cables should be used in power transmission at home and abroad
Overhead cable manufacturers believe that the resistivity of metal conductors in insulated cables is very small; the resistivity of insulators is very high. The reason why insulators can insulate is because the positive and negative charges in the insulator molecules are tightly bound, there are few charged particles that can move freely, and the resistivity is high. Therefore, in general, the macroscopic current generated by the movement of free charges under the action of an external electric field can be ignored, and it is considered to be a non-conductive substance. For insulators, there is a breakdown voltage that gives electrons enough energy to excite them. Once the breakdown voltage is exceeded, the material is no longer insulating.
Overhead cable (full name overhead insulated cable) is an overhead conductor with an insulating layer and a protective sheath. Aerial cable is a special cable manufactured by a production process similar to cross-linked cable, and it is a new transmission method between overhead conductors and underground cables.
Power cable manufacturer: It is very inconvenient to have water in the power cord. So far, there is no particularly reasonable way to deal with it. Replacing a cable is rather difficult without making an intermediate connector. Therefore, when the cable has water, it is generally necessary to take precautions.
1KV cable manufacturers: ordinary socket wire selection criteria: ordinary socket 2.5 square meters is enough. Generally, the load of the wire needs to be controlled within 2500 watts, but if you consider the frequent use of high-power electrical appliances, you can choose a 4 square wire.
