AXQJ EMC 1kV Cable

What is AXQJ EMC 1kV Full Screen Cable?

The AXQJ EMC 1kV Full Screen Cable is a low-voltage, screened four-core power distribution cable featuring sector-shaped stranded aluminium conductors, XLPE insulation, an HFFR inner sheath, an annealed copper wire full concentric screen with an opposite open copper helix, and a black UV-resistant HFFR outer sheath conforming to SS-EN 60228 Class 2, SS 424 14 18, and HD 603 S1/5P standards. Designed for an operating voltage of 1kV, it provides exceptional electromagnetic compatibility (EMC) and low smoke zero halogen safety across critical industrial networks.

Engineered to suppress electromagnetic interference and protect personnel and equipment during fire emergencies, the cable combines low-loss XLPE core insulation with a heavy-duty copper wire concentric screen. Its dual HFFR bedding and sheath layers emit zero corrosive halogen acid gases and minimal smoke during combustion, while its robust construction permits versatile installation indoors, outdoors in free air, underground in ground trenches, or submerged in water.

AXQJ EMC 1kV Cable Construction

• Conductor: Sector-shaped stranded aluminium conductors (Class 2) complying with SS-EN 60228, engineered to reduce overall cable diameter and installation weight.
• Insulation: Cross-Linked Polyethylene (XLPE) delivering high dielectric strength, continuous 90°C thermal rating, and short-circuit withstand up to 250°C.
• Inner Sheath: Extruded Halogen-Free Flame Retardant (HFFR) compound providing mechanical cushioning and core stabilization.
• Screen: Full concentric screen consisting of annealed copper wires bound with an opposite open helix of copper, delivering comprehensive EMC protection and earth continuity.
• Outer Sheath: Heavy-duty Halogen-Free Flame Retardant (HFFR) compound, UV-resistant and self-extinguishing.
• Core Identification: 4 core: Blue, Brown, Black, Grey.
• Sheath Colour: Black.

Applications

AXQJ EMC 1kV Full Screen Cables are purpose-built for primary electrical distribution, variable frequency drive motor circuits, and critical infrastructure networks where full metallic shielding and halogen-free fire safety are essential.

• Direct Ground Burial & Underground Trenches: Utility power networks installed directly in soil, open outdoor trenches, and moisture-prone cable raceways.
• Submerged & Water Installations: Feeder runs submerged in waterways, retention basins, and channels under standard static water conditions.
• Industrial Frequency Inverters & Processing Facilities: Variable speed drives and manufacturing machinery requiring complete copper screening to mitigate high-frequency harmonics.
• Public Infrastructure & Tunnels: Indoor and outdoor air-laid tray installations in transit tunnels, hospitals, and high-occupancy buildings requiring zero halogen emissions.

Frequently Asked Questions

Q: What engineering advantages do sector-shaped aluminium conductors offer over circular designs?
A: Sector-shaped conductors interlock compactly to eliminate interstitial voids, reducing the overall cable diameter and weight, which lowers transportation costs and simplifies handling during pulling operations.

Q: How does the annealed copper wire screen with an opposite open helix ensure EMC compliance?
A: The concentric annealed copper wires combined with the counter-wound copper helix provide low electrical transfer impedance and high shielding coverage, effectively containing high-frequency emissions and preventing cross-talk.

Q: Is AXQJ EMC 1kV cable suitable for outdoor and submerged water installations?
A: Yes, the cable is certified for fixed installation indoors, outdoors in free air, directly in ground trenches, and submerged in water under standard operating conditions.

Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We accept standard international commercial payment terms including Telegraphic Transfer (T/T, with 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
