Hoëspanning kabels
Hoëspanning kabels can be divided into aluminum-core high-voltage cables and copper-core cables according to different materials. Voltage Level Range: 6/64 kV, 48/66 kV, 66/120 kV, 127/220 kV and other ultra-high voltage. Due to the complex environmental conditions and special requirements in certain areas, die gebruik van koperkernkabels is meer betroubaar in terme van kwaliteit en veiligheid. According to our production experience, the selection of technical specifications and cross-sectional area of high-voltage cables should be made with reference to the surrounding environment, the corresponding laying method 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 grade Celsius, the lifespan can be as long as 40 jare.
2. 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. Environmental Protection: 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.

Laying of VERI High Voltage Cables
Inspeksie voor kabellegging: of die model en spesifikasies aan die vereistes voldoen, die isolasie moet goed wees, die voorkoms moet volledig wees, en daar moet geen spore van trauma wees nie.
'n Spaar lengte moet naby die kabelterminal gereserveer word, en 'n ekstra lengte moet gereserveer word vir die direk begrawe kabel in die golfvormige lê. Die afstand tussen elke steunpunt van die kabel moet wees soos gespesifiseer in die ontwerp. Wanneer daar geen ontwerpregulasies is nie, dit moet nie groter wees as rubber kabels. These plastic cables are horizontal 1M, vertikaal 2M, and cables suspended on steel cables that are horizontal 0.75M. Die buigradius van die kabel moet nie minder wees as 10 keer die buitenste deursnee van die kabel (gepantserde of ongepantserde meerkern plastiek geïsoleerde kragkabel).
Wanneer die kabels gelê word, die kabels moet uit die boonste punt van die katrol getrek word, and avoid friction and drag of the wires on the bracket and the ground. Die kabels moet nie gekruis word tydens lê nie, hulle moet netjies gerangskik wees, and fixed, en tekens moet geïnstalleer word. Daar moet stewige stokke by die hoeke van die direk begrawe kabels wees. Wanneer kabels in kabelslote ingaan, tonnels, geboue, en pype, die ingange en uitgange moet gesluit wees. Klemme en toebehore vir AC enkelkern kabels moet nie 'n geslote magnetiese stroombaan hê wat uit yster bestaan nie.
