3.6/6 (7.2)kV Voltage
Application
.MV cables with a voltage level of 3.6/6 (7.2) kV are widely used in medium voltage power systems and are suitable for industrial, commercial and municipal power transmission and distribution. Due to its good voltage breakdown resistance and mechanical strength, it is particularly suitable for use in underground laying, pipelines, troughs, overhead lines, and wet or dry environments.
Feature
MV cables use copper conductors to provide excellent conductivity, which can efficiently transmit power while ensuring stable current transmission. Inner semi-conductive layer: The inner semi-conductive material is used to evenly distribute the electric field, prevent electric field concentration, reduce the electrical stress of the insulation layer, and improve the overall stability of the cable. Cross-linked polyethylene (XLPE) insulation material has excellent electrical properties and heat resistance, and can withstand normal operating voltages up to 6kV, as well as higher impulse voltages, ensuring long-term stable operation.
Certification
MV cables have passed various certifications, and certified cables are an important process to ensure that they meet international and regional safety, performance, environmental and quality standards. To ensure the reliability and safety of power transmission, MV cables must pass strict certification tests during the production process to verify their applicability in various environments.

FAQ
Q: Which type MV cable shall not be used unless identified for the use?
2. Cables Not Rated for Wet Locations
Q: How to select mv cable size?
2. Determine the appropriate voltage rating for the cable.
3. Check the ampacity using manufacturer tables or software to select the correct conductor size.
4. Ensure the voltage drop remains within acceptable limits (3-5%).
5. Consider short-circuit rating to withstand fault currents.
6. Account for ambient temperature and installation conditions to adjust the cable size.
7. Add safety margins to handle variations in load and environmental conditions.
8. Choose the conductor material (copper or aluminum) based on the application and cost considerations.
