Medium voltage power cable is a key component in modern electrical distribution systems. It transfers electricity between substations, transformers, industrial facilities, utility networks, renewable energy systems, and other major electrical loads.
Compared with ordinary low-voltage cable, medium voltage power cable requires a stronger insulation system and more carefully designed electrical shielding. XLPE insulation is widely used because it provides excellent dielectric performance, thermal stability, and dependable long-term operation.
Jianyun Cable supplies XLPE medium voltage power cable with copper or aluminum conductors, PVC outer sheathing, and multiple armored construction options for underground, industrial, utility, and infrastructure applications.
Recommended Medium Voltage Power Cable:
XLPE Medium Voltage Power Cable from Jianyun CableMedium voltage power cable is designed for electrical systems operating above conventional low-voltage distribution. Typical medium-voltage applications include power networks ranging from several kilovolts up to approximately 35kV.
The Jianyun Cable product range includes working voltage classes from 3.6/6kV through 26/35kV. These cables are designed for power transmission and distribution in underground networks, industrial facilities, substations, and infrastructure projects.
Depending on the project, the cable can use copper or aluminum conductors and may include additional armor to protect against mechanical stress.

Contact Jianyun Cable for XLPE Medium Voltage Power CableMedium voltage power cable is used to transmit electrical energy between substations, transformers, industrial facilities, utility networks, renewable energy systems, and major electrical loads.
Typical options include 3.6/6kV, 6/10kV, 8.7/15kV, 12/20kV, 18/30kV, 21/35kV, and 26/35kV, depending on project requirements.
XLPE provides strong dielectric insulation, good thermal stability, low dielectric loss, and dependable long-term performance under medium-voltage electrical stress.
Armored cable should be selected where additional protection is required against impact, compression, pulling force, ground movement, or other mechanical stresses.
SWA uses steel wire armor and is commonly applied to multi-core cables. AWA uses aluminum wire armor and is often selected for single-core AC cables because aluminum is non-magnetic.
Cable size should be selected according to system voltage, load current, cable length, voltage drop, short-circuit current, installation environment, ambient temperature, and applicable electrical standards.
