Copper‑Core XLPE‑Insulated PVC‑Sheathed Power Cable

Copper‑core XLPE‑insulated PVC‑sheathed power cable is one of the most widely‑applied general‑purpose power transmission cables in modern‑day power‑distribution systems. Its internal conductive core is made of high‑purity copper, which delivers excellent electrical conductivity, low‑resistance power transmission performance and stable current‑carrying capacity. Cross‑linked polyethylene (XLPE) serves as the main insulating layer. After cross‑linking treatment, polyethylene molecules form a stable three‑dimensional network structure, greatly improving heat‑resistance, insulation strength, anti‑ageing performance and long‑term operational reliability, compared with ordinary thermoplastic polyethylene insulation. The outer polyvinyl chloride (PVC) sheath functions as a mechanical‑protective barrier, shielding the inner insulation and conductor from moisture, dust, sunlight, slight mechanical abrasion and general chemical contamination. Thanks to this multi‑layer composite structural design, the cable balances outstanding electrical performance, mechanical durability and cost‑effectiveness, making it a preferred wiring solution for numerous industrial, municipal and commercial power‑supply projects.

Strict quality‑management standards are followed throughout the whole manufacturing workflow. High‑quality oxygen‑free copper rods are selected and drawn, stranded into compact circular conductors to guarantee stable current‑carrying capability. XLPE insulation is extruded homogeneously around the conductor under precise temperature and pressure parameters, to avoid defects such as bubbles, impurities or uneven insulation thickness. After cabling, the outer PVC sheath is extruded and cooled. Every finished cable undergoes a complete set of inspection tests, including conductor‑resistance measurement, insulation‑resistance detection, high‑voltage withstand test, outer‑sheath visual inspection and dimensional verification. These comprehensive quality‑control measures eliminate hidden risks such as partial discharge, insulation breakdown and outer‑jacket damage, ensuring that each reel of cable can provide long‑term, safe and stable power transmission in different operating environments. This cable is mainly suitable for fixed‑installation power‑transmission and distribution circuits, and it can be laid inside cable trenches, cable ducts, building wall conduits, tunnels and overhead‑support routes. It adapts well to indoor, outdoor and semi‑exposed laying conditions without severe‑mechanical‑damage risks.

The cable exhibits excellent comprehensive performance in practical engineering applications. XLPE insulation can withstand a long‑term conductor operating temperature of 90℃, allowing higher current‑carrying capacity than traditional PVC‑insulated power cables. Its low dielectric‑loss characteristic reduces energy waste during long‑distance electric‑energy transmission. The PVC outer sheath offers decent waterproof and anti‑pollution properties for general‑industrial and municipal environments. The whole‑cable structure is compact and easy‑to‑handle during transportation, laying and terminal‑connection construction. With reliable anti‑ageing performance, it achieves a long expected service life under normal operating conditions, effectively lowering the cycle of circuit renovation and maintenance costs for project owners. It is widely adopted for power supply of production equipment, lighting circuits, control‑room power loops and auxiliary‑facility distribution lines.

Our copper‑core XLPE‑insulated PVC‑sheathed power cables and the full spectrum of our cable‑product portfolio are extensively deployed in metallurgy, electric‑power, energy, chemical industry, construction, shipbuilding, transportation and many other industrial sectors, as well as a large number of national key infrastructure‑construction projects.

Within the metallurgical industry, these cables are used for main power‑supply circuits of smelting equipment, rolling‑production‑line distribution loops, raw‑material‑handling‑system wiring and auxiliary‑facility power‑transmission lines inside metallurgical plants. Metallurgical workshops contain large‑scale continuous‑running equipment with high‑power consumption, requiring stable long‑term power delivery. Our XLPE Insulated Power Cables guarantee steady electric‑energy supply for metallurgical production systems, supporting safe and uninterrupted industrial manufacturing.

In the electric‑power sector, this cable series plays an important role in urban and rural power‑grid renovation projects, substation low‑voltage outgoing‑line circuits, power‑plant auxiliary‑equipment distribution loops and community power‑supply trunk‑lines. Urban power‑distribution networks cover wide‑ranging municipal zones, residential districts and commercial‑building clusters. The dependable insulation performance of XLPE ensures safe power transmission for regional grids, reducing circuit‑fault incidents and improving the stability of urban power supply.

For energy‑development projects, the cables are applied to on‑site power‑distribution systems of photovoltaic power stations, wind‑farm internal power loops, oil‑and‑gas‑field auxiliary‑equipment wiring and energy‑storage‑station low‑voltage power‑supply circuits. New‑energy projects are often constructed in open‑air zones with complex natural‑environment conditions. The robust structure of our copper‑core XLPE‑insulated PVC‑sheathed cables adapts well to field‑site laying requirements and delivers reliable power‑transmission support for renewable‑energy‑generation facilities.

Chemical‑industrial parks deploy this cable type for power‑supply circuits of production reactors, pumping‑station equipment, workshop lighting loops and automated‑control‑system power‑distribution wiring. General‑grade anti‑corrosion performance of the PVC outer sheath can satisfy routine laying demands inside chemical‑plant zones without highly‑concentrated corrosive‑gas environments, providing stable electric power for chemical production workflows.

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

Apart from conventional industrial‑and‑civil‑engineering applications, our copper‑core XLPE‑insulated PVC‑sheathed power cables have been adopted in numerous national‑level key‑construction initiatives. These projects include cross‑regional power‑grid upgrading schemes, large‑scale new‑energy‑base construction, high‑speed‑rail supporting‑power projects, industrial‑park infrastructure development programs and major municipal reconstruction works. National strategic construction places high‑standard requirements on circuit safety and long‑term reliability. Our cables provide stable, high‑quality electric‑energy transmission to support the smooth implementation of these important national‑engineering tasks.
