What are the types of high-voltage cables?

Speaking of high-voltage cables, we must all be familiar with it, but we are also very unfamiliar with the basic information about this product. In fact, the high-voltage cable is a kind of power cable, which refers to the power cable used to transmit between 1kv and 1000kv, and is mostly used for power transmission and distribution. Its conductor material is copper, aluminum, and steel core aluminum stranded wire. The standard used when it is used is GB/T12706-2008, and the temperature of the device is above 0°C. It is usually used at a normal temperature of 90°C. These are some basic information about high-voltage cables. Here we at Shenyang Cable Factory still need to tell friends what are its varieties? In fact, there are many types of high-voltage cables. The common ones we have are YJV cables, VV cables, YJLV cables, and VLV cables. The full name of YJV is actually XLPE insulated PVC sheathed power. The full name of VV is PVC insulated PVC sheathed power, YJLV generally calls it XLPE insulated PVC sheathed aluminum core power, VLV calls it PVC insulated PVC sheathed aluminum core power cable. If the type is different, its function will be different at the time of use. In the future, we must be clear about our needs when buying.

Therefore, there are many types of high-voltage cables. Because of the good conductive function of copper conductors, copper core power cables are used as the main road of the power supply system in many projects, while aluminum core power cables are less used. , Especially in the higher voltage power system, the more copper core cables are selected. The structure of this high-voltage cable is relatively simple. The main components from the inside to the outside include conductor, insulation, inner sheath, filler, and outer insulation. Of course, armored high-voltage cables are mainly used for underground burying. When in use, they can resist high-strength squeezing on the ground and prevent damage from other external forces. Therefore, its advantages are also very clear. Generally speaking, the requirements for this product are relatively high when it is used. We must find a regular manufacturer to buy it when we purchase it. In short, high-voltage cables are suitable for communication with rated voltages of 35KV and below for power transmission and distribution. The long-term working temperature of the cable conductor is 90 degrees, and the temperature of the cable conductor does not exceed 250 degrees.
