Industrial Applications

 

Commercial High-Rises: Emergency lighting, smoke extraction blowers, and fire suppression pumps during active fires.
Public Transit: Underground power distribution in metro systems, airport passenger terminals, and rail tunnels.
Petrochemical Plants: Main power feeds for high-risk crude refining, gas processing, and chemical units.
Power Generation: Auxiliary power and control circuits in thermal, hydroelectric, and solar plant control rooms.
Mining & Heavy Industry: Subsurface distribution networks exposed to severe vibration and mechanical impact.

 

Custom Manufacturing Options

 

Oxygen-Free Copper (OFC) or Class 2 aluminum conductors tailored to specified resistance limits.
Tinned copper wire braiding or copper tape screening for EMI suppression in signal circuits.
Flame-retardant LSZH, oil-resistant PVC, or specialized anti-termite outer sheathing compounds.
Custom drum lengths supplied on steel-wood or iron-wood drums matched to project cable schedules.

 

Manufacturing Control

 

Extrusion Processing: Dry nitrogen-gas XLPE extrusion lines ensure consistent insulation wall thickness without micro-voids.

Standard Compliance: Batch-tested for fire resistance (IEC 60331), acid gas release (IEC 60754), and smoke density (IEC 61034).

In-Line Electrical Testing: Continuous spark testing and 100% high-voltage dielectric testing on every production lot.

Quality Traceability: Mill Test Certificates (MTC) and Factory Acceptance Test (FAT) reports included with each shipment.

 

Supply Capacity

 

Order Scaling: Minimum order quantity of 1,000 meters for custom runs, supporting project orders up to 500 km.

Export Packaging: Fumigated wooden reels or steel-wood drums sealed with heat-shrink moisture-barrier wrapping.

Lead Time: 15 to 25 working days from technical drawing sign-off to factory release.

Shipping Documentation: Certificate of Origin (CO/Form E), Packing List, Commercial Invoice, and Bill of Lading provided.

 

Factory Capabilities

 

Facility Scale: 150-acre production plant, 800+ workforce, and annual capacity exceeding 50,000 km of cable.

ISO Certifications: Certified management systems under ISO 9001 (Quality), ISO 14001 (Environment), and ISO 45001 (Safety).

Vendor Experience: Contract supplier for national power utilities, global EPC contractors, and public infrastructure projects.

Global Export Reach: Direct export footprint across 40+ countries in Southeast Asia, the Middle East, Africa, and South America.

FAQ

 

Q: What is the current-carrying capacity difference between copper and aluminum conductor versions?

A: At the same cross-sectional area, copper conductors carry approximately 1.6x the current-carrying capacity of aluminum.

Q: How can we verify the ATEX and IECEx certificate numbers?

A: The ATEX and IECEx certificate numbers and issuing notified body can be provided as PDF copies within 2-3 business days of request.

Q: What is the expected insulation service life when continuously operated at the rated 90°C conductor temperature?

A: XLPE insulation rated at 90°C continuous operation typically provides a service life of 20-25 years under standard IEC 60216 thermal aging models.

Q: What happens if a batch fails the IEC 60331 fire resistance test after arrival at the destination port?

A: Buyers must submit a claim with test evidence within 15 days of port arrival, after which a credit note or free replacement is issued within 10 business days upon verification.

Q: Does the direct-burial installation option require any additional mechanical protection beyond the standard FR PVC/LSZH sheath?

A: For direct burial without a duct, an additional steel wire armor (SWA) layer is recommended for mechanical protection against soil settlement and accidental digging damage, available as a custom construction option.
