Copper‑Core XLPE‑Insulated Non‑Magnetic‑Wire‑Armoured PVC‑Sheathed Power Cable

Copper‑core XLPE‑insulated non‑magnetic‑wire‑armoured PVC‑sheathed power cable is a heavy‑duty, mechanically‑reinforced power‑transmission cable designed for installation environments where strong magnetic‑field interference must be avoided. Its conductive core is manufactured from high‑purity copper conductor material, which ensures excellent electrical conductivity, low transmission loss and stable long‑term current‑carrying capacity. Cross‑linked polyethylene (XLPE) forms the primary insulating layer. After cross‑linking treatment, polyethylene molecules create a stable three‑dimensional network structure, greatly improving heat‑resistance performance, insulation strength, anti‑ageing capability and electrical reliability compared to ordinary polyethylene insulation. The special non‑magnetic metal‑wire armour layer is wrapped around the insulated cores. Unlike conventional steel‑wire armour, this non‑magnetic structure will not produce induced‑magnetic‑loss heating, avoiding extra energy consumption, local overheating and electromagnetic‑field distortion. The outermost polyvinyl‑chloride (PVC) sheath provides comprehensive mechanical protection against moisture, dust, chemical splashes, sunlight ageing and minor external impact damage. Thanks to this multi‑layer composite structure, the cable achieves a perfect balance of outstanding electrical performance, powerful mechanical‑impact resistance and low‑magnetic‑interference characteristics, making it the preferred wiring choice for industrial facilities, power‑grid substations and engineering projects sensitive to magnetic‑field disturbance.

Every production procedure follows strict quality‑control specifications. High‑quality oxygen‑free copper rods are drawn and stranded into compact conductors to guarantee stable load‑carrying performance. XLPE insulation is extruded evenly on the conductor surface under precisely‑controlled temperature and pressure, eliminating hidden defects such as air bubbles, impurities or uneven insulation thickness. After core‑stranding, non‑magnetic metal wires are wrapped uniformly to form the armour layer, with strict control over winding density and tightness. Finally, the outer PVC sheath is extruded and cooled. Each finished cable undergoes a full series of performance tests, including conductor‑resistance testing, insulation‑resistance measurement, high‑voltage withstand inspection, armour‑layer continuity check and outer‑jacket dimensional verification. These rigorous inspection workflows prevent risks such as partial discharge, insulation breakdown, armour‑layer fracture and sheath damage, ensuring that every cable reel can deliver safe, long‑term and stable power‑transmission service in complex‑condition engineering sites. This cable is mainly intended for fixed‑installation power‑transmission and distribution circuits. It is suitable for laying underground, inside cable trenches, tunnels, cable ducts and other locations exposed to potential mechanical extrusion and impact, where magnetic‑loss‑free operation is required. It adapts well to indoor, outdoor, underground and semi‑exposed laying environments.

This cable exhibits comprehensive advantages in practical engineering applications. XLPE insulation allows the copper conductor to operate continuously at 90 °C, delivering higher current‑carrying capacity than traditional PVC‑insulated cables. Its low dielectric‑loss property reduces energy waste during long‑distance power transmission. The non‑magnetic metal‑wire armour greatly enhances mechanical‑damage resistance, protecting internal insulation and conductors from crushing, sharp‑object piercing and external impact during underground burial or tunnel installation. Most importantly, the non‑magnetic armour material avoids magnetic‑induction‑caused heat generation, which is critical in environments around precision‑instrument workshops, substation control‑rooms and signal‑sensitive equipment. The outer PVC sheath offers excellent waterproofing, dust‑proofing and general‑corrosion‑resistance properties for most industrial‑site conditions. The cable structure is compact, convenient for transportation, laying and terminal‑connection construction. Its outstanding anti‑ageing performance extends its service life under normal‑operation conditions, reducing circuit‑renovation frequency and overall maintenance costs for project owners. It is widely deployed to supply power for heavy‑duty production equipment, large‑scale distribution‑loops, precision‑instrument power‑supply circuits and auxiliary‑facility transmission‑lines.

Our copper‑core XLPE‑insulated non‑magnetic‑wire‑armoured PVC‑sheathed power cables and our complete cable‑product portfolio are extensively applied in metallurgy, electric power, energy, chemical industry, construction, shipbuilding, transportation and many other industrial sectors, as well as numerous national key infrastructure‑construction projects.

Within the metallurgical industry, these cables serve as heavy‑load main power‑supply circuits for smelting equipment, rolling‑production‑line distribution loops, raw‑material‑handling‑system wiring and auxiliary‑facility power‑transmission lines inside metallurgical plants. Large‑scale metallurgical workshops contain massive power‑consuming equipment and complicated electromagnetic‑field environments. The non‑magnetic‑armour design prevents extra‑heat generation caused by magnetic‑induction loss, while the reinforced armour layer resists mechanical impact from on‑site construction operations. Our cables guarantee stable electric‑energy delivery for metallurgical production systems and support safe, uninterrupted industrial manufacturing.

In the electric‑power sector, this cable series is widely used for substation outgoing‑line circuits, power‑plant auxiliary‑equipment distribution loops, urban underground power‑grid trunk‑lines and power‑supply circuits near control‑room precision instruments. Power‑grid‑related sites contain a large number of electromagnetic‑field sources. Using non‑magnetic‑armoured cables effectively avoids local‑overheating risks and electromagnetic interference, improving the operational safety and stability of power‑distribution networks.

For energy‑development projects, the cables are deployed in on‑site underground power‑distribution systems of photovoltaic‑power stations, buried internal‑power loops for wind‑farm facilities, oil‑and‑gas‑field auxiliary‑equipment wiring and energy‑storage‑station underground low‑voltage power‑supply circuits. New‑energy facilities are frequently built in open‑air zones with complicated natural‑environment conditions and underground‑laying requirements. The strong mechanical protection from the non‑magnetic‑wire armour adapts perfectly to underground‑burial demands, delivering reliable power‑transmission support for renewable‑energy‑generation equipment.

Chemical‑industry parks adopt this cable type for underground‑buried power‑supply circuits of production reactors, pumping‑station equipment, workshop‑lighting loops and automated‑control‑system power‑distribution wiring. The PVC outer sheath satisfies routine anti‑pollution requirements inside most chemical‑plant zones, while the reinforced armour layer protects cables buried underground from soil‑extrusion damage, providing stable electric‑power supply for chemical‑production workflows.

In the construction industry, the cables are widely used for buried main‑power‑supply trunk‑lines of high‑rise commercial buildings, underground‑distribution circuits of industrial plants, municipal‑engineering underground‑power‑supply systems and underground‑garage heavy‑load power loops. Ship‑building and marine‑engineering projects select these cables for shore‑based buried dock‑facility power‑distribution circuits and on‑land ship‑repair‑shop underground wiring systems, meeting land‑side buried‑cable power‑transmission demands of marine‑industry facilities. The transportation industry makes full use of the cables for underground highway‑service‑area power‑supply circuits, buried railway‑station auxiliary‑equipment distribution loops, traffic‑hub underground‑power‑transmission lines and tunnel‑facility buried‑power‑supply wiring.
