Copper Core XLPE Insulated Steel Tape Armored PVC Sheathed Power Cable

Product Overview

The copper core XLPE insulated steel tape armored PVC sheathed power cable is a high-performance, high-voltage power transmission product designed and manufactured for medium and high-voltage power distribution systems. Structurally, the cable adopts high-purity copper conductors as the core conductive medium, cross-linked polyethylene (XLPE) as the main insulating layer, steel tape armoring as the mechanical protective layer, and polyvinyl chloride (PVC) as the outer protective sheath. This multi-layer composite structural design perfectly integrates excellent electrical insulation performance, strong mechanical protection capability, outstanding anti-compression and anti-tensile properties, as well as superior environmental adaptability. After professional cross-linking treatment, the XLPE insulation material features stable molecular structure, strong heat resistance, excellent electrical insulation strength, low dielectric loss and outstanding anti-aging performance, which can maintain stable insulating performance under long-term high-load operation and complex environmental conditions. The internal steel tape armoring layer greatly enhances the cable’s ability to resist external mechanical extrusion, impact damage and tensile force during laying and long-term underground operation, effectively avoiding core damage caused by external construction disturbance and ground pressure. The outer PVC sheath provides reliable protection against moisture, dust, chemical corrosion and ultraviolet aging, greatly extending the overall service life and operational stability of the cable.

Product Application Scope

This series of high-voltage power cables is specially applicable to power transmission and distribution projects with a rated voltage range from 6kV to 35kV, covering the mainstream medium and high-voltage power supply grades required for industrial production, urban power grid construction, energy engineering and key infrastructure construction. As the core transmission carrier of medium and high-voltage power systems, the product undertakes the key tasks of long-distance electric energy transmission, regional power distribution and stable power supply for major equipment. Different from low-voltage ordinary cables, 6kV to 35kV high-voltage cables have extremely high requirements for insulation uniformity, voltage withstand performance and operational safety. With ultra-high insulation stability and standardized structural design, our XLPE armored high-voltage cables can effectively avoid insulation breakdown, partial discharge and line leakage faults under high-voltage operating conditions, ensuring continuous, safe and stable operation of high-voltage power transmission lines.

The product is suitable for various complex laying environments, including direct buried laying, cable trench laying, underground pipe gallery laying, tunnel laying and outdoor overhead fixed laying scenarios. The built-in steel tape armoring structure enables the cable to adapt to harsh construction environments such as road backfilling, ground pressure bearing and construction machinery rolling, which is very suitable for urban underground power grid transformation and industrial park buried power transmission projects. At the same time, the excellent anti-corrosion and moisture-proof performance allows the cable to operate stably in humid, saline-alkali and chemically slightly corrosive environments, solving many common quality problems of ordinary high-voltage cables such as easy aging, poor pressure resistance and short service life in complex working conditions.
