Explore our flagship certified cables designed to satisfy British, French, American, and IEC standards under extreme industrial loads.
Why professional power grids, smart manufacturing facilities, and heavy-duty environments rely on audited structural wiring.
CE marking verifies that dual-core cables meet rigorous European Union directives for health, safety, and environmental protection. For international procurement managers, importing CE-certified 2-core power lines ensures hassle-free customs clearance and verified fire safety resistance parameters under LVD (Low Voltage Directive).
2-core cable configurations isolate phase and neutral or dual power lines within specialized outer jacketing. This design reduces electromagnetic interference, optimizes thermal dissipation ratios, and ensures steady current flow for low-voltage applications up to 0.6/1KV.
From industrial automation lines to complex offshore installations, modern setups demand materials that resist chemicals, oils, and intense mechanical pull. Advanced insulation materials (XLPE, LSZH, PVC) ensure durability, protecting conductors from thermal overload and chemical erosion.

Cross-linked Polyethylene (XLPE) offers superior electrical properties over traditional PVC. It has a higher thermal threshold of 90°C (compared to PVC's 70°C under continuous load), meaning it can carry higher currents under the same nominal cross-sectional area. XLPE also features excellent resistance to chemical corrosion, ozone weathering, and mechanical abrasion, reducing electrical leakage and line losses in long-distance grids.
CE marking for 2-core power cables demands conformity under the Low Voltage Directive (LVD) 2014/35/EU. The cables must pass insulation resistance tests, voltage withstand testing (applying 3.5kV AC for 5 minutes without breakdown), and structural dimensional checks. If used in permanent installations within buildings, compliance under the CPR (Construction Products Regulation) EU 305/2011 is mandatory, requiring verified fire behavior and low toxic gas emission profiles.

Get answers to critical technical questions regarding compliance, performance, and customization.
CE certification guarantees that the 2-core cable complies with European Union health, safety, and environmental standards. Specifically, it ensures the cable meets the requirements of the Low Voltage Directive (LVD) 2014/35/EU and the RoHS Directive, confirming it has undergone dielectric strength, conductor resistance, and insulation elongation testing.
XLPE (Cross-linked Polyethylene) offers a higher continuous operating temperature limit of 90°C compared to PVC's limit of 70°C. It features superior tensile strength, chemical resistance, and lower dielectric loss. Consequently, XLPE-insulated 2-core cables can safely handle higher load currents, making them ideal for modern industrial distribution networks.
Yes, but direct burial requires appropriate outer armor protection. For 2-core cables, we offer Steel Wire Armor (SWA) or Steel Tape Armor (STA) configurations. SWA provides robust longitudinal tension protection, ensuring the conductors remain safe from physical shearing or rodent damage underground.
We perform end-to-end digital monitoring on our state-of-the-art intelligent production lines. Each batch is subjected to routine and sample tests in our dedicated testing laboratories, which include tests for electrical resistance, flame retardancy (IEC 60332), thermal stability, and mechanical strength, ensuring compliance with BS, NF, ASTM, or IEC standards.
For installations in public spaces, commercial complexes, and transit systems where fire safety is paramount, we supply 2-core LSZH cables. In the event of a fire, these cables emit minimal smoke and zero toxic acid gases (halogens), preventing visibility loss and protecting both personnel and sensitive electronic systems.
