Insulated Power Cable: The Core Backbone of Global Energy 

Transmission and Infrastructure Upgrade

In the era of global energy transition and accelerated infrastructure construction, the demand for stable, efficient, and safe power transmission solutions is soaring. As the core carrier of power transmission, insulated power cable has become an indispensable key component in fields such as new energy power generation, smart grids, urban rail transit, and industrial manufacturing. According to the latest industry report, the global insulated power cable market scale is expected to maintain a steady growth rate of 6.5%-8.0% in the next five years, with the new energy sector's demand accounting for as high as 25% by 2026. For engineering contractors, power operators, and industrial enterprises, choosing a high-quality insulated power cable not only ensures the safety and stability of power transmission but also directly affects the overall efficiency and long-term return on investment of the project.

Insulated power cable refers to a power cable with an insulating layer wrapped around the conductor, which can isolate the conductor from the outside world and prevent short circuits and electric leakage. With the continuous advancement of material science and manufacturing technology, modern insulated power cable has evolved from the early rubber-insulated and paper-insulated types to a variety of high-performance products such as cross-linked polyethylene (XLPE) insulated power cable, fire-resistant insulated power cable, and low-smoke halogen-free insulated power cable. These products have their own characteristics and are widely used in different scenarios, forming a complete product system that covers low-voltage, medium-voltage, and high-voltage power transmission needs.

Core Advantages: Why High-Quality Insulated Power Cable Is Indispensable for Major Projects

The quality of insulated power cable directly determines the reliability of the entire power system. Our insulated power cable series has won wide recognition from global customers with four core advantages, solving the pain points that have long plagued the industry such as rapid insulation aging, insufficient load capacity, and poor environmental adaptability.

First, superior insulation performance ensures long-term stable operation. We adopt advanced XLPE cross-linking technology, which makes the insulation layer of the high-voltage insulated power cable have excellent heat resistance and chemical corrosion resistance. The operating temperature can reach up to 90℃, and the service life is as long as 30 years, which is 20% higher than the national standard. In practical applications, this means that the frequency of maintenance and replacement of cables is greatly reduced, and the secondary rectification cost caused by insulation aging is saved for customers. A large-scale photovoltaic power station project in Southeast Asia used our XLPE insulated power cable, and after three years of operation in a high-temperature and high-humidity environment, the insulation performance remained stable, with no power failure caused by cable problems.

Second, excellent load capacity adapts to the peak demand of the power system. The conductor of our industrial insulated power cable is made of high-purity oxygen-free copper, with a conductivity of more than 99.95%, and the current-carrying capacity is 15% higher than the national standard. This enables the cable to easily cope with the peak load of industrial production and large-scale power consumption scenarios. A machinery factory in East China replaced the original ordinary cable with our industrial insulated power cable, and the problem of production line shutdown caused by cable heating during peak production was completely solved. The factory feedback showed that the cable temperature only reached 45℃ after 12 hours of continuous operation, far lower than the national standard limit of 70℃.

Third, comprehensive environmental adaptability meets the needs of diverse scenarios. Whether it is a cold alpine region, a humid coastal area, a high-temperature industrial workshop, or a flammable and explosive chemical zone, we have corresponding insulated power cable products. Our fire-resistant insulated power cable has passed the Class A test of GB 31247-2014, which can maintain power supply for 180 minutes in an 800℃ flame, providing a reliable power guarantee for the fire protection system of high-rise buildings and key projects. The corrosion-resistant insulated power cable adopts a special XLPE insulation layer, which can resist acid and alkali corrosion for 1000 hours, and is widely used in chemical industrial zones and mining areas.

Fourth, green and environmental protection complies with global sustainable development trends. With the increasing emphasis on environmental protection in various countries, the demand for green and low-carbon products is growing. Our low-smoke halogen-free insulated power cable uses degradable polyolefin materials, with a smoke density grade of ≤50 and a recovery rate of more than 95%, which is far higher than the national standard. This product has been widely used in green grid projects and renewable energy power stations, helping customers achieve environmental protection goals while ensuring power transmission safety. It is predicted that the proportion of environmentally friendly insulated power cable in the global market will reach 65% by 2026, becoming the mainstream product in the industry.

Scenario-Based Application: Tailor-Made Insulated Power Cable Solutions for Different Industries

Different industries and application scenarios have different requirements for insulated power cable. We adhere to the concept of scenario-based customization and provide targeted solutions for new energy, industrial manufacturing, infrastructure construction, and other fields, helping customers maximize the value of power transmission systems.

In the field of new energy, the insulated power cable for renewable energy has become a key supporting product for photovoltaic and wind power generation. The new energy power generation scene has the characteristics of harsh outdoor environment and long transmission distance. Our insulated power cable for renewable energy is specially designed with anti-ultraviolet and anti-aging insulation materials, which can withstand the test of extreme weather such as strong wind, heavy rain, and high temperature. At the same time, the low attenuation design ensures that the power loss during long-distance transmission is less than 0.12dB/km, improving the overall efficiency of the power station. Up to now, our products have been applied in more than 50 new energy projects around the world, with a total supporting capacity of over 10GW.

In industrial manufacturing, industrial insulated power cable is the "blood vessel" of the production line. Different manufacturing industries have different environmental characteristics: the automobile parts factory has oil pollution, the glass factory has high temperature, and the heavy machinery factory has frequent mechanical collisions. Aiming at these characteristics, we have developed a series of special industrial insulated power cables. The oil-resistant insulated power cable uses nitrile rubber sheath, which can operate stably in an oil-polluted environment for a long time without cracking; the high-temperature insulated power cable can operate continuously at 125℃, adapting to the high-temperature working environment of glass and metallurgical factories; the anti-mechanical damage insulated power cable adopts steel wire armoring, with a compressive strength of more than 1000N/cm², which can withstand the rolling of forklifts and the collision of heavy equipment. These products have helped hundreds of industrial enterprises solve the problem of frequent cable failures and improved production efficiency.

In infrastructure construction, insulated power cable is an important part of urban energy supply and transportation systems. Urban rail transit, commercial complexes, and municipal road lighting have high requirements for cable safety and laying flexibility. Our flexible extruded insulated power cable adopts a special conductor stranding process, with a bending radius of only 6 times the cable outer diameter, which is much smaller than the national standard of 10 times. This greatly reduces the difficulty of laying in complex spaces such as commercial complexes and subway tunnels, and shortens the construction period by 15% compared with traditional cables. In a high-rise residential project in a first-tier city, our fire-resistant insulated power cable ensured that the fire protection system maintained power supply during the fire drill, and the project passed the fire acceptance at one time.

In special environments such as marine engineering and mining areas, the requirements for insulated power cable are more stringent. Our submarine insulated power cable adopts double-layer steel wire armoring, with a compressive strength of more than 2000N/cm², which can withstand the pressure of deep-sea environments and ensure the normal operation of offshore oil exploration and marine wind power projects. The explosion-proof insulated power cable meets the GB 3836.1-2010 standard, which effectively prevents explosion accidents in underground mining scenarios and guarantees the safety of workers' lives and property.
