YJV and BVV cables can be said to have a high degree of coincidence in many aspects. For example, in practical applications, both YJV and BVV cables are often used in outdoor lighting street lamp systems. Both can also be used to transmit electrical energy. YJV cable and BVV cable have many differences in signal, voltage and characteristics.
First, let’s briefly introduce the YJV cable and BVV cable:
Full name of BVV cable: copper core PVC insulatedPVC sheathed round sheathed cable
YJV cable full name: XLPE insulated and PVC sheathed power cable
Although YJV cable and BVV cable have a high degree of overlap in practical applications, there are actually quite a few differences between the two. The first is the difference in voltage. The voltage level of BVV is 300/500V, while the voltage level of YJV cable is common. Three gears: low voltage 0.6/1KV, medium voltage 6/10KV, high voltage 26/35KV, etc.
Secondly, the side structures of YJV cable and BVV cable are different. BVV sheathed cable is a commonly used cable in a typical weak current system. Its structure is composed of two or more BV cables plus an outer sheath layer. The core is round wire, and the double core is flat wire.
In addition, there are 3 cores, 4 cores, 5 cores, 3+1 cores, 3+2 cores, 6 cores, 7~24 cores and other specifications. The YJV is a cross-linked cable, and its basic structure is composed of three parts: conductor, insulation and sheath. If there are special requirements, YJV cable will also have a shielding layer or armor layer, etc., and the number of cores, YJV is more than BVV type Few, only single core, 2 core, 3 core, 4 core, 5 core, 4+1 core, 3+2 core, 3+1 core.
In terms of characteristics, BVV cables and YJV cables are also different. BVV is a common home improvement cable. It has excellent characteristics such as corrosion resistance, moisture resistance, and oil resistance for household use. Its working temperature cannot exceed 65 degrees Celsius, while YJV cables are traditional The above is defined as a power cable, which can operate normally in an environment not exceeding 90 degrees Celsius, has excellent electrical performance, and also has excellent characteristics such as stability, light weight, and small outer diameter.
Although in many practical applications, BVV and YJV can meet the requirements at the same time, because of their different characteristics, many specific uses are also different. For example, BVV cable is suitable for power frequency rated voltage 300/500V It is used to install power cords for electrical appliances and below, and is often used for surface-mounted wires, such as the laying of household appliances, lighting circuits, and electrical equipment. YJV cables are suitable for fixed installations in distribution networks or industrial installations with rated power frequency voltages of 0.6/1KV and above, such as urban power grids, mines, and large factories.
It is precisely because of the development of technology that various industries are involved in more and more fields and more and more demands. In order to better serve production, wires and cables will develop products with different characteristics and models. The specific characteristics and use methods of cable products can make the best use of their materials and give play to their best characteristics.
