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.

In-depth Analysis of Industry Requirements: The operational environment within the new energy sector typically involves unmanned facilities exposed to harsh conditions (intense ultraviolet radiation, significant diurnal temperature fluctuations, wind and rain erosion), with extreme sensitivity to power generation efficiency. The long-term weather resistance, temperature tolerance, DC voltage endurance, and mechanical strength of cables directly impact the efficiency, reliability, and return on investment of power generation systems. For instance, within photovoltaic systems, a cable's DC resistance and heat resistance impact overall system efficiency. In wind farms, a cable's resistance to twisting directly relates to turbine maintainability and lifecycle costs.
Henghui Cable's Core Solutions: Henghui Cable possesses a deep understanding of the unique characteristics of new energy technologies, providing a comprehensive range of cable products spanning the entire chain from generation to transmission, and extending to energy storage and charging. We employ specially modified cross-linked polyolefin materials, enabling cables to withstand temperature variations from -40°C to 120°C or wider ranges, alongside intense ultraviolet radiation. Optimised conductor and insulation designs minimise DC resistance, reducing energy losses. For mobile applications, dedicated torsion and bending designs ensure exceptionally long service life in dynamic environments.
Typical Application Examples:
① Photovoltaic cables: As photovoltaic technology advances towards higher voltages to reduce line losses, Henghui's PV cables have emerged. Featuring dual-layer irradiation-crosslinked halogen-free materials, these cables excel in DC voltage rating, high-temperature resistance (e.g., 120°C), and current-carrying capacity. In large-scale Gobi Desert photovoltaic power stations, this cable reduces the number of series connections, lowering system costs. Its superior heat resistance also permits higher current carrying capacity at elevated ambient temperatures, thereby enhancing the overall power generation efficiency of the photovoltaic array.
