Zhongdong Cable manufactures medium voltage cables for utility distribution, substations, industrial power systems, renewable energy projects and infrastructure networks. Our MV cable range is available with copper or aluminum conductors, XLPE insulation, metallic screening, and armoured or unarmoured constructions.
Common voltage ratings include 6/10kV, 8.7/15kV, 12/20kV and 18/30kV. Cables can be manufactured according to IEC 60502-2 and customized to meet project specifications.
Choose the cable construction according to the installation route, mechanical protection requirements and project environment.
Suitable for protected ducts, cable trays, substations and indoor distribution systems.

To recommend a suitable MV cable construction, our engineering team normally evaluates the following project information.
Zhongdong medium voltage power cables are designed for power transmission between transformers, switchgear, substations and major electrical loads.
Zhongdong integrates cable production, engineering and quality inspection within a 67,000㎡ manufacturing facility. Quality control covers raw materials, conductor processing, insulation, screening, sheathing and finished cable testing.
Supports production across multiple cable structures and voltage classes.
Used for dimensional, electrical, mechanical and voltage-withstand inspections.
Engineering support for conductor, armour, screen and sheath selection.
ISO management systems, CE, EAC and CNAS laboratory capabilities support project quality control.
For distributors, contractors, EPC companies and utility projects, Zhongdong can manufacture medium voltage cables according to cable schedules, technical datasheets and tender specifications.
Common voltage classes include 6/10kV, 8.7/15kV, 12/20kV and 18/30kV. Other project-specific configurations can also be evaluated.
Yes. Both copper and aluminum conductors are available depending on ampacity, cable weight, installation requirements and project budget.
Unarmoured cables are generally used in protected routes such as ducts and trays. Armoured constructions provide additional protection against mechanical damage and installation stress.
Yes. Applicable medium voltage cable constructions can be manufactured according to IEC 60502-2, with conductor requirements according to IEC 60228 where required.
Please provide voltage rating, conductor material and size, number of cores, armour type, sheath material, standard, quantity, installation environment and required drum length.
Send us your voltage class, conductor size, cable construction, installation conditions and required standard. Our engineering team will review your specification and recommend a suitable MV cable solution.

Embedded within our premier Medium Voltage Cable echelon, the STA Armoured Cable tier represents the engineering benchmark for direct-burial utility corridors and regional power lines facing continuous surface load. The integration of dual-layered, helically applied galvanized steel tape armour provides a robust physical barrier that effectively counters severe crushing forces and subterranean shifting, ensuring absolute phase stability and zero mechanical degradation over decades of heavy-duty operation.
·Standards: IEC 60502-2
·Cores: 1 Core, 3 Cores (Note: For single-core AC lines, non-magnetic Stainless Steel Tape Armor (SSTA) is used to eliminate eddy currents. 3-Core circuits utilize conventional steel tape)
·Conductors & Screening: Copper or Aluminum conductors backed by premium CTS or CWS capacitive shielding.
·Material Matrix: Formulated with 90°C XLPE insulation. The bedding layers and outer jackets can be matched interchangeably between PE and PVC to fight chemical soil corrosion.
·Optional Upgrade: To survive marshy land or high-water-table routes, longitudinal water-blocking swelling tapes are available upon request to halt axial moisture ingress.
Key Advantages
·Zero Thermal Loop Losses: Implementing SSTA (Stainless Steel Tape Armor) on all 1-Core layouts disrupts the magnetic loop. This completely eliminates eddy current heat generation, protecting the system's total ampacity.
·Subterranean Biological Defense: The overlapping metallic tape barrier provides absolute structural resistance against heavy soil compression, while permanently denying penetration from destructive underground termites and rodents.
·Harsh Environment Adaptability: For chemical refineries or severe industrial zones, the external jacket can be fortified with optional fire-barrier mica layers or advanced self-extinguishing compound jackets on demand.
Application Guideline
·Choose STA: Ideal for direct underground burial and sub-grade utility trenches requiring standard radial crush defense.
·Choose SWA: Highly discouraged for environments featuring continuous vertical suspension, steep inclines, or high-tensile pulling risks. For those conditions, please view our SWA high-tensile series.
Zhongdong Cable combines premium raw materials, large-scale manufacturing capabilities, and strict quality control systems to deliver cable products that fully match your technical requirements and brand identity.
