Guangzhou Nanyang Cable is a large-scale wire and cable manufacturing enterprise in South China, its predecessor was established in 1985 as a collective ownership enterprise Shantou Nanyang Cable Factory, and its trademark "NAN Nan Brand" was also created in the same year. Nanyang Cable's parent company, Nanyang Tianrongxin, has strong competitiveness in the domestic wire and cable capital market, and its comprehensive strength ranks among the top 20 in the industry.
 
Nanyang Cable products are the most prominent low-voltage cables, and it is an important supplier of power engineering and transmission and distribution system projects of China Southern Power Grid and State Grid. The cloth wire belongs to the low-voltage wire series of Nanyang Cable, and the strong current products mainly include BV, BVR, BVV and BVVR. The nominal cross-sectional area of the single-strand single-core BV line of Nanyang Cable is within 6 square meters, which is suitable for home improvement wiring; BV wire above 6 square is made of 7 strands of copper wire, and the conductor is a stranded structure similar to BVR wire, but the hardness is still higher than that of BVR wire, and most of them are construction wires.
 
The cores of BV, BVR, BVV and BVVR four kinds of cloth wires are made of 99.99% Chilean oxygen-free copper, and the factory has a number of German Sikora online diameter measurement and deviation measurement production lines to ensure that the finished wire diameter is sufficient, not loss-making, and the insulation is not biased. The insulating material is imported PC, which is flexible, not easy to break, and low smoke and flame retardant, so all the cloth wires of Nanyang Cable have certain flame retardant characteristics. Its flame retardant grade is national standard C, the wire can withstand short-term fire, and can be extinguished instantaneously when leaving the open flame, which will produce a small amount of white smoke; Although the flame retardant grade is not high, the C grade flame retardant has strong practicability for basic home decoration.
 
Among the four major products, BVV and BVVR plastic sheathed wires are only more common in South China, also known as double plastic wires, that is, a layer of PVC sheath is added on the basis of BV wires to form a simple structure of single-core hard conductor PVC insulation PVC sheath. Due to its own sheath, this BVV line can be laid directly in concealed projects, omitting the pipe threading process, which is convenient and trouble-free. However, many urban buildings now require the use of wire conduit in concealed works, so for the conduit wire, conventional BV wire is sufficient. In addition, the BVV wire is also available in a multi-strand soft wire version, and the construction principle is the same as that of the hard wire.
 
Nanyang Cable's products are rarely sold online and can generally be purchased in physical stores in South China. The price of BV line 2.5 square is 171 yuan / circle, and the price of BVR line is about 150 yuan per circle.
