Structure

It is composed of three parts: wire core, insulation layer and protective layer. The wire core is used to conduct current and is generally twisted by multiple strands of copper wire or multiple strands of aluminum wire. Low voltage cable has single core, double core, three core, four core and so on. Two-core cables are used for single-phase lines, three-core and four-core cables are used for three-phase three-wire lines and three-phase four-wire lines, respectively, and single-core cables can be applied to single-phase or three-phase lines as needed. Commonly used low-voltage cable core cross-sectional area of 10,16, 25, 35, 50, 70, 95, 120,150, 185, 240 mm and so on.

Speculiarity

Low-voltage cable has the characteristics of reliable operation, no pole, no ground occupation, no visual obstruction, little influence from the outside world, etc., and has been widely used in low-voltage distribution system.

JiangnanLow-voltage cable is used for transmission and distribution of electric energy cable, often used in Chengpei underground power grid, power station leading lines, industrial and mining enterprises internal power supply and underwater transmission lines across the river and sea.

1. Aluminum core cables should be used in general environments and places, but copper core cables should be used in places with intense vibration and special buildings and special requirements;

2. Buried cables are generally armored cables with outer protective layer. In places where there is no possibility of mechanical damage, plastic sheathed cables and lead (aluminum) covered cables with outer sheaths can also be used;

3. In the soil with chemical corrosion or stray current corrosion, buried cables should not be used as far as possible. If it must be laid in the ground, anti-corrosion cables should be used;

4. Cables laid in tubes or tubes are generally plastic sheathed cables, and armored cables can also be used;

5. The cables laid in the cable trench or cable tunnel should not be flammable or flammable outer protective layer. armored cables, plastic sheathed cables and lead (aluminum) covered cables are generally used;

6. When the cable is laid in a place with a large height difference, plastic insulated cables, non-dripping cables and dry insulated cables should be used.

Jiangnan Cable's medium and high-voltage workshop is a place where advanced production technologies converge. It is equipped with the concentric high-speed stranding machine production line imported from Germany, as well as SKETT's concentric stranding machine and other high-end equipment.

Concentric high-speed stranding machine production line imported from Germany greatly improves the production efficiency with its high-speed and accurate stranding capacity. Each stranded wire can be guaranteed to be of high quality under high speed operation, which ensures high efficiency and stability in the production of medium and high voltage cables.

SKETT's concentric stranding machine is the best of its kind. It realizes high-precision concentric stranding, resulting in a tight and uniform cable stranding structure. This unique process not only enhances the mechanical strength of the cable to withstand strong external forces, but also optimizes the electrical performance, effectively reducing resistance and signal loss, laying a solid foundation for the superior quality of medium and high-voltage cables, and making Jiangnan Cables stand out in the market.

NO.1, Jiangnan Cable has advanced production technology and equipment. From the manufacturing of conductors to the processing of insulation, shielding and sheathing, every step is precise and strict to ensure the high quality of medium voltage cables.

NO.2, the quality control is extremely strict. The company has established a perfect quality inspection system, from the selection of raw materials to the finished products leaving the factory, checking at every level. Each medium-voltage cable has to go through a number of strict tests to ensure that the products meet or even exceed the national standards.

NO.3, Jiangnan Cable has invested heavily in research and development. According to the market demand and customers' special requirements, we can develop medium voltage cables with different characteristics, such as better environmental resistance and better current carrying capacity. Moreover, the rich product line can meet the different needs of various complex projects and provide customers with one-stop cable solutions.
