Railway Cable Manufacturers

Where Our Rail & Transit Cables Fit

Rail transit imposes some of the most demanding cable requirements of any sector: continuous vibration, mechanical shock, humidity, chemical exposure and strict fire safety. Our rail and transit cables are built for two broad duty zones — moving equipment and fixed infrastructure.

• Rolling stock: traction motors, auxiliary power, control and instrumentation wiring inside vehicles, where flexibility and vibration resistance are critical.
• Tram and light rail power supply: medium-voltage feeders connecting substations to the overhead or ground-level contact system.
• Fixed transit infrastructure: tunnel lighting, station power distribution, signalling and communication circuits requiring low smoke and halogen-free performance.

Our Rail & Transit Cable Range

The current rail and transit range is centred on a 10 kV XLPE insulated power cable for tram power supply system engineering. This cable is a representative example of how we combine conductor shielding, cross-linked insulation and halogen-free sheathing for transit duty.

Construction and Material Options

We build rail and transit cables around the conductor, insulation, shielding and sheath combination that matches the installation. For the 10 kV tram power cable, the standard construction uses a round compacted copper conductor, cross-linked semi-conductive conductor and insulation shielding, XLPE insulation, copper tape metallic shielding, galvanised steel strip armour and a 125°C halogen-free low-smoke flame-retardant cross-linked polyolefin outer sheath.

• Conductor: round compacted copper for stable electrical performance and reduced outer diameter.
• Insulation: cross-linked polyethylene rated for 90°C continuous conductor temperature and 250°C short-circuit temperature for up to 5 seconds.
• Metallic shielding: copper tape wrapping; temperature monitoring optical fibre can be added on request.
• Armour: galvanised steel strip for mechanical protection in buried or ducted routes.
• Outer sheath: halogen-free low-smoke flame-retardant cross-linked polyolefin, black or project-specific colour.

Critical Specifications for Transit Projects

Transit cable selection depends on a small set of parameters that drive both safety and service life. We confirm these against the project specification before releasing a quotation.

Configuration and Customisation

We produce both standard and customised rail and transit cables. Customisation can cover conductor size, core count, sheath colour, core identification method, fire performance grade and additional protective features such as termite resistance, rodent resistance and UV resistance.

• Core identification by coloured ribbon or printed numbers, or to customer requirements.
• Sheath colour black or project-specific.
• Optional temperature monitoring optical fibre within the cable structure.
• Armour and shielding combinations to suit buried, ducted or overhead installation.

For projects that also require transmission or industrial cabling, our Power Grid Transmission & Transformation Cables and Industrial Cables ranges use compatible material and quality systems.

Quality Assurance and Acceptance

Every metre of cable undergoes checks from raw material intake to finished product delivery. Our quality management system is certified, and we operate an MES system for end-to-end digital control from raw materials to finished goods. For rail and transit cables, routine tests cover conductor resistance, insulation resistance, dimensional checks and voltage withstand. Fire performance tests are conducted according to the applicable standard for flame retardant, low smoke and halogen-free grades.

We can supply test certificates and compliance documentation with each delivery. Where a project requires third-party witness testing or specific acceptance protocols, we confirm the test plan before production.

Installation, Maintenance and Serviceability

Rail and transit cables must withstand constant movement, bending and mechanical impact. Correct installation practice protects service life: maintain the specified bending radius, secure cables with appropriate clamps to minimise vibration damage, and separate power, signal and control cables to avoid interference.

• Inspect insulation wear, connector integrity and mechanical damage during scheduled maintenance.
• Check sheath condition at entry and exit points where cables pass through walls or trays.
• For rolling stock, verify flexibility and strain relief at moving joints.

We provide spare parts and technical support for the service life of the cable. Our after-sales team covers the full process from pre-sales technical review to post-delivery follow-up.

Information We Use to Configure Your Solution

To prepare an accurate configuration and quotation for rail and transit cables, we need the following project inputs. Providing these at enquiry stage shortens the technical review and avoids later specification changes.

Frequently Asked Questions

What voltage levels do your rail and transit cables cover?

Our rail and transit range includes low-voltage rolling stock cables up to 1 kV and medium-voltage tram power supply cables at 8.7/10 kV. For broader transmission needs, we manufacture power cables up to 110 kV and below.

Can you customise cable construction for a specific transit project?

Yes. We develop and manufacture products based on customer-provided drawings or samples. Customisation covers conductor size, core count, sheath colour, core identification, fire performance grade and additional protective features.

What fire safety standards do your transit cables meet?

Our rail and transit cables use halogen-free, low-smoke, flame-retardant materials. The 10 kV tram power cable is available with flame retardant A/B grade, low smoke and halogen-free performance, and we test to the applicable standard for each grade.

What is the minimum order quantity and delivery time?

Minimum order quantity varies by product; most cables have a minimum of 200 metres. Delivery time is approximately 7 to 10 days, depending on specification and quantity.

Do you provide test certificates and documentation?

Yes. We supply test certificates and compliance documentation with each delivery. Where third-party witness testing or specific acceptance protocols are required, we confirm the test plan before production.

Where are your rail and transit cables manufactured?

We manufacture at our facility in Guanlin Town, Yixing City, Jiangsu Province, China. Our production base covers approximately 200,000 square metres with two production plants and nine specialised workshops.
