The corresponding rated current-carrying capacities of these four specifications are 130A, 165A, 205A, and 250A respectively. Different cross-sectional areas and current-carrying capacities enable the cable to flexibly adapt to equipment of different powers in the power station, from precision instruments in the main control room to high-power equipment such as generator sets and transformers, and a suitable specification can be found for each.
The
Copper Conductor has a copper content of over 99.9% and a conductivity of more than 58MS/m. This parameter ensures the efficiency of the cable in power transmission, which can effectively reduce losses. Even under high current loads, it can maintain stable conductive performance, ensuring the continuity and reliability of power transmission.
The temperature resistance range of the XLPE insulation layer can reach -40℃ to 90℃, which means the cable can still work normally in the extreme temperature environment that may occur in the power station. Its insulation resistance is ≥1000MΩ, and the high insulation resistance characteristic can effectively resist voltage fluctuations and instantaneous impacts, fundamentally reducing the risk of electric leakage and ensuring the safety of power transmission.
The outer
PVC Sheath has a tensile strength of ≥12MPa and a uniform thickness. This parameter ensures that the sheath has sufficient mechanical strength to withstand long-term mechanical damages such as friction and collision. At the same time, the cable has good overall
Flexibility, with a minimum bending radius of 12 times the conductor diameter. This specification facilitates laying and installation in the narrow space of the power station.

(III) Material and Style
Conductor Material: Nyy Cable uses high-purity copper as the conductor material, with a copper content of more than 99.9%. High-purity copper has excellent conductive performance, with a conductivity of more than 58MS/m, which can transmit power efficiently and reduce energy loss during transmission. At the same time, copper has good ductility and toughness, so that the conductor is not easy to break during processing and use, and is convenient for bending and laying of the cable. In addition, copper has good chemical stability, is not easy to be corroded in the complex environment of the power station, can maintain stable conductive performance for a long time, and prolong the service life of the cable.
Insulation layer material: The insulation layer is made of cross-linked polyethylene (XLPE) material, which is treated with a special cross-linking process. XLPE material has extremely high insulation resistance (≥1000MΩ), which can effectively block the current and prevent electric leakage accidents. It has a wide temperature resistance range, up to -40℃ to 90℃, and can adapt to the extreme temperature environment that may occur in the power station. Moreover, XLPE material has good anti-aging performance and mechanical strength, and is not easy to age and deteriorate due to external factors during long-term use, ensuring the stability and reliability of the insulation layer.
Sheath material: The outer sheath is made of weather-resistant polyvinyl chloride (PVC) material. PVC material has good wear resistance, which can protect the internal conductor and insulation layer of the cable from external mechanical damage, such as friction and collision. It has excellent corrosion resistance, can resist the impact of dust erosion and humid environment in the power station, and ensure that the service life of the cable in complex working conditions is more than 15 years. At the same time, PVC material has a simple processing process, relatively low cost, and certain flexibility, which is convenient for processing and laying of the cable.
In terms of style design, Nyy Cable adopts a circular structure. This structure makes the appearance of the cable regular, and can pass through pipes, trunking, etc. more smoothly during laying, reducing laying resistance. The circular structure is evenly distributed, and the force of each part is relatively balanced, which can improve the mechanical strength of the cable and enhance its stability during use. The overall design of the cable takes into account both functionality and practicality, ensuring good conductive, insulation and protective performance, and being convenient for installation and maintenance.
(IV) Production Process
The production process of Nyy Cable PVC power cable strictly follows high-standard process requirements and integrates a variety of advanced technologies to ensure the quality and performance of the product.
In the conductor manufacturing link, first, high-purity electrolytic copper is selected as the raw material, and strict screening and inspection are carried out to ensure the purity and quality of the copper material. Then, the copper material is drawn into
Copper Wires of the required diameter through the wire drawing process. During the wire drawing process, the drawing speed and tension are precisely controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth. After that, according to the specification requirements of the cable, multiple copper wires are stranded. During the stranding process, the stranding pitch and tension are controlled to make the conductor structure tight and stable, improve the flexibility and mechanical strength of the conductor, and facilitate subsequent processing and use.
The insulation layer is made by a special cross-linking process. After preprocessing the polyethylene material, it is evenly coated on the outside of the conductor through an extruder to form a preliminary insulation layer. Then, the conductor coated with the preliminary insulation layer is cross-linked, usually by means of warm water cross-linking or steam cross-linking. Under specific temperature, pressure and time conditions, the polyethylene molecules undergo a cross-linking reaction to form a three-dimensional network structure. The XLPE insulation layer after cross-linking treatment has significantly improved temperature resistance, insulation and mechanical strength, and can meet the requirements of special environments such as power stations.
The sheath extrusion process is to heat and melt the weather-resistant PVC material, and then evenly coat it on the outside of the insulation layer through an extruder to form the outer sheath. During the extrusion process, parameters such as extrusion temperature, speed and pressure are precisely controlled to ensure that the thickness of the sheath is uniform, the surface is smooth, closely combined with the insulation layer, and free of bubbles, impurities and other defects. The thickness of the sheath is designed according to the specification and use environment of the cable to ensure that it has sufficient mechanical strength and protective performance.
In the entire production process, multiple quality inspection procedures are set up. The diameter, resistance and other parameters of the conductor are tested to ensure that its conductive performance meets the standards; the insulation resistance, temperature resistance and other properties of the insulation layer are tested to ensure that the insulation performance is up to standard; the thickness, tensile strength and other properties of the sheath are inspected to ensure that the protective performance of the sheath is qualified. Only products that pass all inspections can leave the factory, thus ensuring the high quality of Nyy Cable PVC power cable.
