The XLPE insulation system provides stable electrical insulation for medium-voltage distribution. Its performance depends on insulation quality, conductor design, shielding structure and correct installation. The cable specification should be selected according to the rated voltage, operating current, installation environment and applicable cable standard.
The metallic shielding layer provides a controlled electrical path around the insulated conductor and supports the overall insulation system. Proper shielding, jointing and termination are important for maintaining electrical performance after installation, particularly in medium-voltage distribution networks.
Copper and aluminum conductors are available for different project requirements. Copper offers higher electrical conductivity, while aluminum has lower density and can reduce cable weight. Conductor selection should consider current capacity, voltage drop, installation space, cable weight and project cost rather than conductor material alone.
The listed sizes cover different load requirements and installation conditions. Final selection should be based on calculated operating current, allowable voltage drop, short-circuit withstand requirements, ambient conditions, laying method and the applicable electrical design requirements.
For underground utility tunnels, hospitals, rail-transit facilities and other enclosed locations, cable fire-performance requirements should be confirmed during the electrical design stage. Halogen-free low-smoke constructions can be specified where the project requires lower smoke emission and reduced corrosive gases. The required construction should be confirmed against the applicable local standard and project specification.
For long-distance power distribution, cable weight and installation conditions can be important factors in conductor selection. Aluminum conductors can reduce overall cable weight, while copper may be selected where higher conductivity or a more compact conductor arrangement is required. The final choice should be based on the electrical calculation and installation conditions.
For infrastructure and export projects, production records and test documentation help provide traceability from manufacturing to delivery. Qiancheng maintains batch-related production and testing records, which can support customer inspection and project quality documentation according to the order requirements.
Export projects may require factory certificates, inspection records, technical specifications and other supporting documents. Documentation requirements should be confirmed before production so that the supplied documents match the contract, inspection procedure and destination-market requirements.
The product can be used in 6/10kV medium-voltage power distribution systems serving industrial parks, mining facilities, municipal utility tunnels, rail-transit infrastructure, hospitals and urban substations. Cable construction and conductor size should be selected according to the specific installation environment and electrical load.
When the ambient temperature is below 0℃, installation should follow the manufacturer's specified handling temperature. Where preheating is required, the cable should be brought above 5℃ before laying. During installation, avoid excessive bending, impact and contact with sharp edges that could damage the sheath or insulation.
Cable sheaths should be protected against cuts, abrasion and mechanical impact during transportation and laying. For underground installations, appropriate sealing, jointing and termination procedures are needed to limit water ingress. The specified bending radius and pulling tension should also be observed during installation.
Single-core AC cables should not be routed individually through ferromagnetic steel conduits because induced currents can cause additional heating. Where conduit protection is required, the cable arrangement should be designed according to the applicable electrical installation requirements.
The delivery package can include factory certificates, inspection records, technical specifications and batch traceability information according to the order requirements. For overseas projects, Chinese-English documentation can be prepared when required for customs, inspection or project handover.
For specification selection, customers can provide the required voltage level, conductor material, cross-sectional area, cable length, installation method and application conditions. Qiancheng can review these requirements and provide the corresponding product and technical documentation for the order.
A: It is suitable for medium-voltage power distribution systems in industrial parks, mining facilities, municipal utility tunnels, rail-transit infrastructure, hospitals and urban substations. The specific construction should be selected according to the installation environment, load requirements and applicable standards.
A: A halogen-free low-smoke construction can be specified when required by the project. Its fire-performance requirements should be confirmed against the applicable cable standard, local fire code and project specification before production.
A: Selection depends on current capacity, voltage drop, conductor size, cable weight, installation conditions and project cost. Copper is generally considered where higher conductivity is required, while aluminum can be considered when lower cable weight is an important project factor.
A: Production quality is controlled through material inspection, manufacturing-process control and finished-product testing. Batch-related production and test records are maintained to support traceability and customer inspection requirements.
A: Installation should follow the specified minimum handling temperature and manufacturer's instructions. When ambient temperatures are below 0℃, preheating above 5℃ may be required before laying. The cable should also be protected from excessive bending, impact and sharp edges.
A: This arrangement should generally be avoided because a single-core AC cable inside a ferromagnetic steel conduit can generate induced currents and additional heat. The conduit arrangement and cable grouping should be designed according to the applicable installation requirements.
