ВЫСОКАВОЛЬТНЫ КАБЕЛЬ
As HV electric cable, it can be divided into aluminum high-voltage cables and coppers according to different materials. With the complex environmental conditions and special requirements in certain areas, the use of copper core cables is more reliable in terms of quality and safety. According to our construction, the selection of cable models and the cross-sectional area should refer to the surrounding environment, the corresponding means of laying, and the performance of electrical equipment.

Product Structure Features:
1. Has good high-temperature resistance: XLPE insulation uses chemical or physical methods to change the structure of polyethylene molecules into a three-dimensional network structure. The three-dimensional network structure has good heat resistance and can be used in Long-term work at a high temperature of 90 degrees Celsius, the lifespan can be as long as 40 гадоў.
2. It has good insulation performance: polyethylene not only retains the insulation performance of cross-linked polyethylene but also has a further improvement in insulation resistance.
3. High mechanical properties: hardness, stiffness, wear resistance, and impact resistance have been improved
4. Chemical resistance: XLPE itself has strong acid and alkali resistance and oil resistance
5. Ахова навакольнага асяроддзя: Since the products of cross-linked polyethylene combustion are water and carbon dioxide, the environmental pollution is low, and it meets the fire safety requirements.
6. The maximum rated temperature of the cable conductor is 90°C, and the maximum temperature during the short circuit (the longest duration does not exceed 5S) does not exceed 250°C.

УЖЫВАННЕ
The type of these cables uses in electricity distribution lines laying across rivers and valleys where special geographical creatures exist. The conductor of ACSR represents the most important component of an overhead power line because they have to ensure economical and reliable transmission and contribute considerably to the total line costs.
Laying of VERI High Voltage Cables
Inspection before cable laying: whether the model and specifications meet the requirements, the insulation should be good, the appearance should be complete, and there should be no traces of trauma.
A spare length should be reserved near the cable terminal, and a spare length should be reserved for the directly buried cable in the wave-shaped laying. The distance between each fulcrum of the cable shall be as specified in the design. When there are no design regulations, it should not be greater than rubber кабелі. These plastic cables are horizontal 1M, vertical 2M, and cables suspended on steel cables that are horizontal 0.75M. The bending radius of the cable should not be less than 10 times the outer diameter of the cable (armored or unarmored multicore plastic insulated power cable).
When laying the cables, the cables should be drawn out from the upper end of the reel, and avoid friction and drag of the wires on the bracket and the ground. The cables should not be crossed when laying, they should be neatly arranged, and fixed, and signs should be installed. There should be firm stakes at the corners of the directly buried cables. When cables enter cable trenches, tunnels, buildings, and pipes, the entrances and exits should be closed. Clamps and fixtures for AC single-core cables should not have a closed magnetic circuit composed of iron.
