WDZ-VV Low Smoke Zero Halogen Power Cable
1; The main types of high-voltage cables are YJV cable, VV cable, YJLV cable, and VLV cable.
YJV cable full name cross-linked polyethylene insulated PVC sheathed power cable (copper core)
VV cable full name PVC insulated PVC sheathed power cable (copper core)
YJLV full cross-linked polyethylene insulated PVC sheathed aluminum power cable
VLV cable full name PVC insulated PVC sheathed aluminum power cable
Due to the excellent conductivity of copper conductors, more and more projects use copper core power cables as the main path of the power supply system, while aluminum core power cables are used less often, especially in higher voltage power systems, the choice of copper core The more cables there are.
2; high-voltage cable structure; high voltage cable from the inside to the outside of the components include: conductor, insulation, inner sheath, filler (armored), external insulation. Of course, armored high-voltage cables are mainly used for ground-buried, which can resist the high-strength pressing on the ground and prevent other external damage.

4;High-voltage cable use characteristics;This product is suitable for transmission and distribution of 35KV AC rated voltage and can be used for fixed connection line, the highest long-term operating temperature of cable conductor is 90 degrees, short circuit (the longest time does not exceed 5S), cable conductor The maximum temperature does not exceed 250 degrees.
5; UHV cables; 1KV and below are low-voltage cables; 1KV~10KV are medium-voltage cables; 10KV~35KV are high-voltage cables; 35~220KV are UHV cables; UHV cables emerge with the continuous development of cable technology. A kind of power cable, UHV cable is generally used as a middle hinge zone in a large-scale transmission system, and belongs to a high-voltage high-voltage cable, which is mainly used for long-distance power transmission.
Mobile Asphalt Mixing Plant
Mobile Asphalt Mixing Plant is a convenient, efficient and mobile asphalt mixture production equipment, which is suitable for all kinds of road construction and maintenance projects. It has the characteristics of strong mobility, quick installation and easy operation, and can provide high quality asphalt mixture for the project and improve the construction efficiency.
Mobile asphalt mixing plant is mainly composed of mixing host, dosing system, fuel system, support device and dust removal system. Among them, the mixing machine is the core part, which is responsible for mixing various raw materials evenly to produce high-quality asphalt mixture. The dosing system is responsible for adding various raw materials to the mixing machine in a certain proportion. The fuel system powers the entire device, usually using diesel or gasoline. The support unit includes four wheels and a suspension system that allows the device to travel and operate in a variety of terrain conditions. The dust removal system is responsible for collecting dust and exhaust gas generated during the production process to ensure a clean working environment and air quality.
The working process of the mobile asphalt mixing station mainly includes the following steps: First, the various raw materials are prepared and added to the mixing machine through the dosing system. Next, the mixer machine starts to work, mixing the raw materials evenly to produce the asphalt mixture. The asphalt mixture is then transported to the construction site for road paving or maintenance. In the whole process, the operation of the mobile asphalt mixing plant is simple and convenient, and it can be quickly deployed and moved, which greatly improves the construction efficiency.
Compared with the traditional fixed asphalt mixing plant, the mobile asphalt mixing plant has the following advantages: First, it has the characteristics of strong mobility and rapid deployment, and can adapt to a variety of complex terrain and construction environment.
