The main difference between 5kV medium voltage cable, 15kV medium voltage cable, and 35kV mv cable lies in their voltage levels and applicable scenarios.
Firstly, in terms of voltage level, the voltage level of 5kV medium voltage cable is 5kV, the voltage level of 15kV medium voltage cable is 15kV, and the voltage level of 35kV medium voltage cable is 35kV. The definition of these voltage levels is based on the maximum voltage that the cable can withstand, and cables of different voltage levels are suitable for different power transmission needs.
Secondly, from the perspective of applicable scenarios, medium voltage cables are mainly used to transmit medium voltage electricity, such as distribution lines in urban power grids. 5kV medium voltage cables are suitable for distribution systems with lower voltage requirements, 15kV medium voltage cable are suitable for distribution systems with medium voltage requirements, and 35kV medium voltage cable are suitable for distribution systems with higher voltage requirements. The selection of these cables depends on specific power transmission and distribution requirements, as well as the design and specification requirements of the system.
Finally, in terms of performance and safety, as the voltage level increases, the insulation materials and structural design of cables also need to be more complex and reliable. High voltage cables (such as 35kV medium voltage cable) require higher safety standards and stricter testing during design and manufacturing to ensure stable operation in high voltage environments. In addition, cables of different voltage levels have different requirements for installation and maintenance to ensure the safety and reliability of the system
