At present domestic ABC cable is used more and more, and all enterprises are producing and market development needs various ABC cable. In daily sales and production, there are still customers put forward, ordering the BLX cable, and alternative ABC cable. According to the market survey, the domestic mainstream wire and cable manufacturing enterprises no longer produce the dragon core cable, so the difference between the two cables made some comments:

1, low voltage ABC cable companies, the current domestic production, with the national standard GB / 12527-2008 1kV rated voltage T and high above the cable is based. This standard is the latest version of the national standard revised edition 2008.

Special insulated ABC cable is mainly used for bundling wires, lead, and other places, the insulation material with special weather resistance insulated ABC cable materials, ABC cable insulation structure has the advantages of being so simple, safe, and reliable, the mechanical and physical properties and excellent electrical properties, environmental ultraviolet resistance, weather resistance, because of its insulation.  insulated ABC cable material, allowable working temperature 70 degrees C, 90 degrees C, and electrical insulation properties, volume resistivity greater than 1 x 1012 ohm m. in the construction, the insulated ABC cable laying gap can be reduced, saving the transmission line corridor, reduce the voltage drop; in use, can reduce the power supply accidents, ensure personal safety.

2, in the current domestic production of BLX type cable, mainly based on JB / t1601-1993 rated voltage 300 / 500V rubber insulating fixed wiring ", released in 1993 standard has in the past 20 years has not been updated, the products in the market have gradually been replaced by ABC cable.

BLX type rubber insulated wire is suitable for AC rated voltage Uo/U 300 / 500V and the following electrical equipment and lighting system, long-term working temperature is 65. Its structure is the aluminum conductor, the outer insulation, the outer braided wire, and then the asphalt coated, its function is the anti-ultraviolet ray. This cable is used two years ago, often due to wind and the sun caused by the woven glass fiber, damage, resulting in their own life being short, poor anti-aging, and the occurrence of environmental pollution.

Along with the continuous renewal of national standards for cable products, according to the national security and reliability of power demand, wire cloth BLX performance is not as good as the ABC cable, so the market insulation ABC cable has gradually replaced the BLX type cable.
