Low Voltage Power Cable Turnkey Project
The power industry is a basic industry for economic development. In the power system, power cable is a cable product that transmits and distributes high-power electrical energy in the main line, it is the nerve of the power system and plays a pivotal role in the whole transmission and distribution system.
Power cables can be divided into low voltage, medium voltage, high voltage, ultra-high voltage and other products of different voltage levels. Among them, low-voltage power cables generally refer to the rated voltage of 0.6/1.0kV cable products, which are the most basic and widely used category of products in the entire power cable product category. Compared to higher voltage power cables, low-voltage power cables have a simple structure, fewer production processes, low investment in equipment and high demand for products. In view of these characteristics, low-voltage power cables have always been the preferred production product for new investment in cable plants in various countries.
Over the past decades, LINT TOP has carried out a large number of turnkey projects for low-voltage power cables in many countries and regions such as North Africa, South Africa and South America, and we have provided our customers with complete project services and technical support, mainly including: helping customers to design the detailed structure of the cable, helping customers to calculate the cable production capacity, reasonably allocating the number of production equipment, helping custom
equipment, helping customers to reasonably arrange the plant, providing a complete set of production equipment from drawing and annealing to the finished product packaging of a full set of production equipment, to provide all the testing equipment required for routine testing, sampling testing and type testing of cables, to provide all the auxiliary equipment, bobbins, moulds, etc., to provide the various raw materials required for cables, etc.
In the past we completed the whole plant project of low-voltage power cables, involving product types such as round, fan-shaped (straight fan-shaped, pre-twisted fan-shaped) armoured (steel wire armoured, steel belt armoured) and non-armoured cables; conductor cross-section mainly 630m2 and below; conductor category mainly class1, class2, class5; insulation cores (1 to 5) cores, mainly 4 cores and 5 cores, where 4 cores also include 3+1 cores, 5 cores also include 3+2 cores and 4+1 cores; involving product standards such as IEC 60502, DIN VDE0276.
