Building Wires and Cables Turnkey Project
1.Overview
Building wires and cables are the most widely used type of electrical equipment wire and cable products, mainly refers to the fixed laying and mobile use of wire and cable for low-voltage power distribution, the rated voltage level is generally 450/750V and below. In our production and life, the construction line is closely related to us, from the power supply in the building to the normal operation of the factory equipment, are inseparable from these products, now and in the future the construction line will play a pivotal role.
Over the past decades, LINT TOP has carried out a large number of turnkey projects for construction lines in North Africa, South Africa, South America and many other countries and regions. We have provided our customers with a complete range of services and technical support, including: assistance in the design of the detailed cable structure, supply of complete production equipment from drawing and annealing to coil packaging, supply of all testing equipment for routine, sample and type tests, supply of all auxiliary equipment, bobbins, moulds, etc., and supply of all raw materials required for the cables.
In the past, we have completed projects for the whole building line, involving specific product types such as unjacketed cables for fixed wiring, sheathed cables for fixed wiring, flexible cables, etc.; conductor cross-sections of 1.5mm2 to 6mm2, but also 10mm2 and above; conductor categories of class1, class2, class5; insulation cores of (1 to 5) cores. The product standards involved are IEC 60227 series, DIN VDE 0281 series, etc.
