In-depth Analysis of Industry Requirements: The power transmission and distribution sector serves as the ‘artery’ for electricity conveyance. Its operational environment is complex and variable, potentially confronting challenges such as high altitudes, extreme temperature differentials, high humidity, and intense electromagnetic fields. The industry's demands for cables far exceed those of ordinary power transmission, centring on exceptionally high reliability, long-term operational stability, and the capacity to withstand extreme electrical and environmental stresses. Any cable failure could trigger widespread power outages, causing substantial economic and societal disruption. Consequently, critical priorities include insulation design, material processing, shielding efficacy, and long-term ageing performance.
Henghui Cable's Core Solutions: Henghui Cable delivers comprehensive cable system solutions spanning power generation, transformation, transmission, and distribution. We specialise in utilising ultra-pure cross-linked polyethylene (XLPE) materials, employing advanced production techniques such as CCV (Chain-Chain Cross-linking) to manufacture high-voltage and extra-high-voltage cables with exceptional electrical performance, outstanding thermal resistance and mechanical strength, and resistance to water tree growth. Additionally, to address specialised environments, we supply specialised cables featuring flame retardancy, fire resistance, termite resistance, rodent resistance, and corrosion resistance, ensuring the robustness and intelligence of power grid infrastructure.
Examples of Typical Applications:
① Ultra-high voltage 110kV cross-linked polyethylene (XLPE) insulated cable systems: This product serves as the backbone for urban grid transmission lines and interregional power interconnections. For instance, in transmission corridors requiring river crossings or traversing densely populated urban areas where overhead lines cannot be installed, Henghui's 110kV XLPE cables are employed for underground installation. Featuring ultra-smooth conductor shielding and insulation shielding combined with dry cross-linking technology, this cable guarantees an impurity-free insulation layer with zero air gaps. Its exceptionally low partial discharge levels enable it to withstand extremely high operating voltages and system short-circuit currents, ensuring absolute safety for national backbone grids.

② Aluminium Alloy Core Overhead Insulated Cable: Specifically engineered for upgrading rural and mountainous grid networks with extended distances and large spans. Compared to conventional copper cables, it achieves a 30% weight reduction while maintaining equivalent conductivity, substantially lowering tower mechanical loads and overall project costs. Its high-strength weather-resistant insulation withstands UV radiation, precipitation, and salt spray corrosion, delivering a service life exceeding 30 years.
