I. Product-Related Information
(1) Specification Parameters
The 0.6/1 Kv XLPE insulated Axmk power cable series, encompassing specifications such as 4X50mm², 4X70mm², 4X150mm², 4X185mm², 4X240mm², and 4X300mm², comes with a comprehensive set of parameters that define its performance and suitability for diverse low-voltage power distribution scenarios.
The rated voltage of all cables in this series is 0.6/1 Kv, which aligns perfectly with the requirements of low-voltage power distribution networks. This voltage rating ensures compatibility with a wide range of electrical systems, including those in industrial plants, commercial buildings, residential complexes, and municipal infrastructure, enabling seamless integration and reliable power transmission.
The 4-core structure (denoted by "4X") is a key design feature, specifically tailored for three-phase four-wire systems. In this configuration, three cores function as phase conductors (A, B, C), responsible for transmitting active power, while the fourth core serves as the neutral conductor, balancing the three-phase currents and maintaining stable voltage levels. This structure is crucial for preventing voltage imbalances that could damage connected equipment and ensuring the efficient operation of the power system.
Current-carrying capacity, a critical parameter indicating the cable's ability to transmit power without overheating, increases proportionally with the conductor cross-sectional area. At an ambient temperature of 25℃, the long-term allowable current-carrying capacities for each specification are as follows:
4X50mm²: Approximately 165A per core, corresponding to a power handling capability of about 36.3kW (calculated using the formula P = √3×U×I×cosφ, where U = 0.4kV, I = 165A, and cosφ = 0.85).
These current and power ratings make the series suitable for a wide range of applications, from powering small to medium-sized machinery to supplying large commercial and industrial facilities.
Physical dimensions vary across the specifications, with outer diameter increasing as the conductor size grows. For instance, the 4X240mm² cable has an outer diameter of approximately 60mm. This dimension is determined by the sum of the thicknesses of the individual components: the XLPE insulation layer surrounding each conductor is about 2.0mm thick, providing excellent electrical insulation to prevent current leakage between cores. The sheath, which can be made of PVC or LSZH, has a thickness of around 2.5mm, offering mechanical protection and resistance to environmental factors.
Other important parameters include the short-circuit withstand temperature and minimum bending radius. The cables can withstand short-circuit temperatures up to 250℃ for a limited duration, which is vital for maintaining power supply during transient fault conditions, allowing protective devices to isolate the fault before permanent damage occurs. The minimum bending radius for fixed installations is 12 times the outer diameter, ensuring that the cable can be bent during installation without compromising the integrity of the insulation or conductor. For example, the 4X240mm² cable has a minimum bending radius of 720mm (12×60mm).
Conductor resistance is another key parameter, with lower resistance indicating better conductivity and reduced power loss. At 20℃, the maximum DC resistance values are:
These low resistance values ensure efficient power transmission with minimal energy loss, contributing to the overall energy efficiency of the power distribution system.

The versatility of the series, combined with its performance characteristics, makes it a go-to choice for various power distribution needs.
(3) Material and Style
The 0.6/1 Kv XLPE insulated Axmk power cable series is constructed using high-quality materials, with a focus on performance, durability, and safety, and features a practical design style that facilitates installation and use in diverse environments.
The conductors are made from high-purity electrolytic copper with a purity of ≥99.95%. This high purity ensures excellent electrical conductivity, which is essential for minimizing power loss during transmission. Copper is chosen for its superior conductive properties compared to other metals, allowing for efficient energy transfer even over long distances. The
Copper Conductors are stranded, consisting of multiple thin wires twisted together, which enhances their flexibility and makes them easier to bend and install, especially in tight spaces or around corners. The stranding also improves the conductor's mechanical strength, reducing the risk of breakage during handling and installation.
The core insulation layer is composed of cross-linked polyethylene (XLPE), a material that undergoes a chemical or physical cross-linking process to form a three-dimensional network structure. This cross-linking significantly enhances the material's properties compared to non-cross-linked polyethylene:
The sheath, which forms the outermost layer of the cable, is available in two material options to suit different application requirements:
Polyvinyl chloride (PVC): PVC Sheaths are cost-effective and offer good resistance to corrosion, chemicals, and abrasion. They are suitable for general-purpose applications in dry or moderately humid environments, such as indoor industrial and commercial settings.
Low smoke zero halogen (LSZH): LSZH sheaths are designed to emit minimal smoke and no toxic halogen gases when burned, making them ideal for use in enclosed spaces, public buildings, and areas with high safety requirements (e.g., hospitals, data centers, and underground tunnels). They also have good resistance to UV radiation and weathering, making them suitable for outdoor applications.
Some models in the series may include an armoring layer for enhanced mechanical protection. Armoring can be made of
Steel Tape or steel wire:
Steel tape armoring: Consists of two layers of steel tape wrapped around the Insulated Cores, providing protection against crushing, puncture, and abrasion. It is commonly used for underground direct burial or installation in cable trays where the cable may be subject to mechanical stress.
Steel wire armoring: Made of galvanized steel wires twisted around the cable, offering higher tensile strength and resistance to pulling forces. It is suitable for applications where the cable needs to be suspended or installed in areas with high mechanical stress, such as in vertical shafts or industrial cranes.
In terms of style, the cables have a cylindrical shape with a smooth outer surface, regardless of the sheath material. The
Stranded Conductors, insulated with XLPE, are twisted together to form a compact core, which is then covered by the sheath (and optional armoring). The outer diameter increases with the conductor size, as previously detailed, ensuring that the cable is proportionate to its current-carrying capacity. The surface of the sheath is often marked with information such as the cable type, specification, rated voltage, manufacturer's logo, and production date, printed at regular intervals for easy identification and traceability. This marking is done using durable ink that remains legible throughout the cable's service life.
The overall design of the cable balances functionality and practicality, ensuring that it can be easily installed using common methods such as direct burial, installation in conduits, or laying in cable trays. The flexibility of the
Stranded Conductors and the smooth sheath surface facilitate pulling and bending during installation, reducing labor costs and installation time.
(4) Production Process
The production process of the 0.6/1 Kv XLPE insulated Axmk power cable series involves several precise and controlled stages, each designed to ensure the final product meets strict quality standards for electrical performance, mechanical strength, and durability.
Conductor Manufacturing: The process begins with high-purity electrolytic copper rods, which are inspected for purity and quality. The rods are first cleaned to remove surface oxides and contaminants using chemical cleaning or mechanical brushing. They are then drawn through a series of dies with progressively smaller diameters in a wire drawing machine, reducing the rod diameter to form thin
Copper Wires. The drawn wires undergo annealing, a heat treatment process performed in a controlled atmosphere (typically nitrogen) at temperatures around 500-600℃. Annealing relieves internal stresses in the wires, improving their ductility and conductivity. Multiple annealed wires are then twisted together in a stranding machine to form the required conductor cross-sections (50mm², 70mm², etc.). The stranding process ensures a compact and uniform conductor structure, enhancing current-carrying capacity and mechanical flexibility.
XLPE Insulation Extrusion: Each stranded conductor is fed into an XLPE insulation extrusion line. The XLPE material, in pellet form, is first dried to remove moisture (moisture content must be less than 0.02% to prevent insulation defects). The dried pellets are fed into an extruder, where they are melted by the heat generated from the rotating screw and barrel heaters. The molten XLPE is forced through a crosshead die, which shapes the insulation around the conductor, ensuring a uniform thickness (e.g., 2.0mm for the 4X240mm² cable). After extrusion, the
Insulated Conductor enters a cross-linking chamber, where the XLPE undergoes cross-linking. This can be achieved through three methods:
Cross-linking transforms the linear molecular structure of XLPE into a three-dimensional network, enhancing its thermal and mechanical properties. The insulated conductor is then cooled in a water bath to solidify the insulation.
Cabling: The four insulated conductors are gathered and fed into a cabling machine, where they are twisted together at a specific lay length to form a round cable core. This twisting ensures the cable has a stable structure and uniform flexibility. A filling material, such as polypropylene rope or non-woven fabric, is often added between the conductors to fill gaps, ensuring a compact core and preventing movement of the conductors during subsequent processing. A binding tape (usually polyester or polypropylene) is wrapped around the cabled core to hold the conductors together and provide additional structural integrity.
Sheath Extrusion: The cabled core (with optional armoring) is fed into a sheath extrusion line. Depending on the selected sheath material (PVC or LSZH), the corresponding pellets are dried and melted in the extruder. The molten sheath material is extruded over the cabled core, forming a continuous outer layer with a thickness of about 2.5mm. The extrusion process is carefully controlled to ensure uniform thickness, good adhesion to the underlying layer, and a smooth surface. For
Armored Cables, the armoring (steel tape or wire) is applied before sheath extrusion: steel tapes are spirally wrapped around the cabled core with overlapping edges, while steel wires are twisted around the core. The sheath material then encapsulates the armoring, providing corrosion protection. The
Sheathed Cable is cooled in a water bath and dried.
Testing and Quality Control: After production, each cable undergoes rigorous testing to ensure compliance with standards. Electrical tests include insulation resistance measurement (using a megohmmeter), withstand voltage testing (applying 3kV for 5 minutes without breakdown), and partial discharge testing to detect insulation defects. Mechanical tests evaluate the tensile strength and elongation of the insulation and sheath materials, as well as the flexibility and impact resistance of the cable. Dimensional checks verify conductor size, insulation and sheath thickness, and overall outer diameter. Additionally, for XLPE insulation, thermal aging tests are performed to confirm long-term heat resistance. Only cables passing all tests are labeled and packaged.
II. General Product Information
