3. Manufacturing Process: From Copper Rod to High-Spec Cable

N2XH 0.6/1kV Cu Cable: XLPE Insulated, LSZH-FRNC Sheathed

1. Copper Wire Drawing: High-purity Cu rods are drawn, annealed & stranded/compacted (Class 1/2, per IEC 60228). 2. XLPE Extrusion: Cross-linked polyethylene is melt-extruded over the conductor using triple-head extruders. 3. Insulation Curing: XLPE layer is cured via CV (Continuous Vulcanization) lines to enhance dielectric strength. 4. Cabling & Assembly: Multi-core twisting and core assembly on S/Z or concentric stranding lines. 5. LSZH-FRNC Sheath Extrusion: Low-smoke zero-halogen sheath is co-extruded to provide flame and smoke performance. 6. Final Testing & QA: Rigorous testing per IEC 60502, ISO 9001, and CPR (EN 50575): conductor resistance, high-voltage withstand, smoke toxicity, flame propagation, dimensional checks. 7. Drum Packaging/Labeling: Each drum marked: batch number, CPR class, country of origin, cable length.

4. Technical Advantages: Why Choose N2XH 0.6/1kV XLPE/LSZH Cable?

Fire Safety: LSZH-FRNC sheath limits halogen gas & smoke (as per IEC 60332-3, IEC 61034, EN 50575), reducing panic & corrosion during fire.
Superior Durability: XLPE insulation is cross-linked, enabling higher thermal limits (+90°C continuous, +250°C in short-circuit).
EMC Compliance: Copper conductor & massive sheath thickness confer immunity to EMI (Electromagnetic Interference), suiting data centers, airports, and process plants.
Environmental Safety: LSZH sheath ensures no dioxins/carcinogens when exposed to fire; meets RoHS2/REACH, chosen for public buildings, hospitals, metros.
Endurance: Service life typically 25-40 years in normal operation; weather/UV/oil/microbe resistance support harsh environments (petrochemical, water treatment).

Q4: Is this cable suitable for outdoor or direct burial?

A: Yes, but for limited extents (up to 0.6/1kV layouts); for direct burial or heavy UV/oil/chemical exposure, specify reinforced sheath or consider armored GSWA braid upon request.

Q5: What is the typical service life and warranty?

A: Expected field service life 25–40 years. Standard warranty offered is 5–10 years depending on project scope and installation assessment.

Q6: What are typical conductor constructions available?

A: Solid (Class 1) or stranded (Class 2) copper, in sizes from 1.5mm²–630mm², as per IEC 60228. Multicore versions for up to 4 or 5 cores (including earth/neutral).
