In power infrastructure projects, the quality and specification of transmission and distribution cables directly impact the safety, efficiency, and longevity of the entire system. As general contractors and power utilities face growing demand for stable electricity supply, the choice of strong, durable cables for generation, transmission, transformation, and distribution lines has become a strategic priority.
We provide the key cable types used in power transmission and distribution networks, with an emphasis on material performance, voltage range, and field application suitability. Each cable mentioned complies with international standards such as IEC, BS, ASTM, and GB/T, ensuring reliable integration into utility and EPC (engineering, procurement, and construction) projects globally.
ACSR conductors are the backbone of overhead high-voltage transmission lines. Their high tensile strength, low line loss, and cost-effectiveness make them ideal for long-span installations in both rural and urban grid systems. The steel core provides mechanical strength, while the outer aluminum strands ensure excellent conductivity.
AAAC conductors offer better corrosion resistance and higher ampacity compared to conventional aluminum conductors. Widely used in coastal and humid environments, these cables reduce maintenance requirements and enhance system lifespan.
XLPE cables are used extensively in underground transmission and substation interconnections. Available in low voltage (LV), medium voltage (MV), and high voltage (HV) configurations, they provide superior thermal and electrical performance, resistance to water ingress, and excellent dielectric strength.
LV XLPE cables (up to 1kV): Used in distribution panels and building connections.
MV XLPE cables (1kV–35kV): Suitable for utility-grade feeders, ring main units (RMU), and primary distribution networks.
HV XLPE cables (above 35kV): Deployed in high-capacity transmission corridors and utility substations.
For underground applications requiring additional mechanical protection, armored cables are a preferred choice. Steel wire armor (SWA) or aluminum wire armor (AWA) ensures durability against impact, rodent damage, and soil movement, making them ideal for direct burial or in concrete cable trenches.
Control cables are essential for signal transmission in automation, SCADA, and substation protection systems. They ensure uninterrupted data flow between control rooms and electrical equipment. Flame-retardant and low-smoke halogen-free (LSZH) versions are commonly used in enclosed environments to meet safety codes.
To support the complete lifecycle of power delivery—from generation at power plants to consumption at end-user facilities—contractors require a versatile portfolio of cables:
Low Voltage Cable (up to 1kV): For building services, lighting systems, and final supply lines.
Medium Voltage Cable (1–35kV): For distribution from substations to industrial or commercial loads.
High Voltage Cable (35kV and above): For long-distance transmission between generation facilities and primary substations.
Each cable type is tested for performance under high thermal loads, voltage stress, and environmental exposure. Custom options such as water-blocked layers, UV-resistant sheaths, and triple-extruded insulation are available to meet the demands of specific projects.
All cables are manufactured in compliance with major global standards:
IEC 60502, IEC 60840, IEC 62067
BS 6622, BS EN 60228
ASTM B232, ASTM B399
GB/T 12706, GB/T 1179
This ensures compatibility with engineering specifications across different national grids and infrastructure projects.
