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.

As a critical infrastructure segment of our Medium Voltage Cable lineup, this Unarmoured Cable range is engineered for fixed primary distribution networks isolated within controlled utility stations, industrial cable galleries, and indoor housing racks. This streamlined series eliminates heavy metal shields to focus purely on spatial density, narrow bending dynamics, and fast routing inside protected pathways.
·Standards: IEC 60502-2
·Cores: 1 Core, 3 Cores
·Conductors & Screening: High-purity Copper or Aluminum conductors wrapped with specialized CTS or CWS screening for electric field equalization.
·Material Matrix: Built with standard 90°C high-ampacity XLPE insulation. External protective jackets can be selected independently between PE and PVC to fit localized thermal layouts.
·Optional Upgrade: Standard outers feature industrial PVC or PE. Halogen-free, low-smoke (LSZH) compound upgrades are accessible on demand to meet strict emission protocols in tunnels and indoor vaults.
Key Advantages
·Congested Route Flexibility: The unarmoured execution minimizes the total cable weight and diameter, allowing fast wire-pulling through continuous bends and heavily cutting engineering manpower expenses.
·Partial Discharge Mitigation: Precision-lapped copper screens provide a uniform electro-static shield around the XLPE cores, effectively grounding charging currents and stopping local insulation breakdown.
·Continuous Batch Tracking: Backed by our native production capacity, we offer flexible contract runs for major utility projects. Every shipment features distinct meter markings to eradicate cutting scrap.
Application Guideline
·Choose Unarmoured: For clean, protected grid locations with zero risk of backfill pressure or impact (e.g., secondary substations, indoor switchgear rooms, or overhead trays).
·Choose Armoured: For applications requiring direct underground trenching, heavy crushing environments, or soil-pest infestations, please refer to our STA / SWA / AWA 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.
