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.
Request a Technical QuoteSWA Armoured Cable
Positioned at the apex of our Medium Voltage Cable engineering sector, this SWA Armoured Cable series is built for high-stress infrastructure layouts requiring maximum longitudinal tensile capacity alongside robust physical armoring against geological displacement. A dense structural cage of round galvanized steel wires (SWA) absorbs immense pulling forces, serving as the main safety standard for vertical or moving soil profiles.
·Standards: IEC 60502-2
·Cores: 3 Cores Exclusively (Note: Ferrous steel wire is strictly forbidden on 1-Core AC lines due to severe magnetic circuit losses; there are no single-core options in this category)
·Conductors & Screening: Copper or Aluminum conductors paired with heavy-duty dual CTS&CWS screening parameters.
·Material Matrix: Designed with high-performance XLPE insulation. This series permits flexible outer sheath selection between PVC and PE components to balance grounding resistance and thermal grid loads.
·Optional Upgrade: Beyond standard PVC/PE options, our production line offers tailored flame-retardant polymers and fire-barrier upgrades for vital emergency loops and high-risk petrochemical grids to prevent continuous fire spreading.
Key Advantages
·High-Drop Tensile Backbone: The heavy, longitudinal steel wire cage locks the cable structure against massive gravitational pulling stress. This prevents inner core elongation or snapping inside steep mine shafts and deep borehole grids.
·Subsidence Mitigation: Offers an advanced mechanical cradle that defends the electric network against jagged rock backfills and shifting soil strata caused by land subsidence or heavy seismic movement.
·Low-Resistance Grounding Path: The massive continuous galvanized wire matrix functions as an ideal, low-impedance fault-current return path, massively upgrading substation system safety during high-amperage faults.
Application Guideline
·Choose SWA: Critical for deep vertical mine installations, borehole power feeds, river crossings, or extreme long-span overhead pulling tasks.
·Alternatives: If longitudinal tensile strength is unnecessary and you require a lighter, lower-cost multichannel line, check out our STA tape series. For 1-Core armoured applications, view our AWA portfolio.
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.
