Introduction: Meeting the Core Demands of Global Energy Interconnection

As the world accelerates the construction of new power systems and energy interconnection becomes irreversible, the stability and adaptability of power transmission have emerged as the most critical demands of the cable industry. Serving as the "energy arteries" of modern society, power cables and niche market leaders concentric cables jointly underpin the efficient operation of industrial production, residential livelihood security, and large-scale cross-border energy projects.

With over 15 years of deep cultivation in the cable manufacturing sector, Zhengzhou Sitong Cable Co., Ltd. has accumulated profound R&D and production expertise in power cables. Its high-performance concentric cables have secured a dominant position in the South American market, and the company is now actively seeking to strengthen cooperation with global partners to expand its international footprint.

Power Cables: Customized Solutions for Diverse Scenarios

Based on in-depth market research and scenario-specific electricity demand analysis, Sitong Cable has developed a diversified power cables system, covering industrial, municipal, residential, and new energy fields. Among them, XLPE insulated power cables and low-voltage power cables have become star products favored by customers for their stable performance and strong adaptability.

Industrial Park Applications: High-Load & Durability

For industrial parks with intensive power consumption and continuous production needs, Sitong’s cross-linked polyethylene (XLPE) insulated power cables are engineered to excel. These cables adopt high-purity oxygen-free copper conductors, which reduce transmission loss by up to 15% compared to ordinary copper conductors, effectively lowering energy consumption for enterprises. The XLPE insulation layer features excellent heat resistance (sustaining stable operation at 90℃ for long periods) and anti-aging properties, making it perfectly suitable for high-temperature, high-humidity industrial environments.

A typical case is the application in a large auto parts industrial park in Henan Province: since the deployment of Sitong’s XLPE insulated power cables three years ago, the park has achieved a 99.9% power supply stability rate, ensuring the uninterrupted operation of 24/7 production lines.

Urban Distribution Network: Flexibility & Installation Efficiency

Against the backdrop of urbanization and old community renovation, low-voltage power cables from Sitong Cable have become the first choice for municipal projects. The products adopt an optimized conductor stranding structure, which increases flexibility by 30% compared to traditional cables, making them easy to bend and lay in narrow spaces such as underground pipe networks and wall cavities. This design reduces on-site installation time by nearly 20%, significantly cutting labor costs for construction teams.

Currently, these low-voltage power cables have been widely used in urban distribution network renovation projects in Zhengzhou, Luoyang, and other cities in Henan Province, winning high praise from local power supply companies for their reliable quality and convenient construction.

Concentric Cables: "Power + Signal" Dual-Drive Creating Multi-Field Value

With the stable supply capacity of power cables as the foundation, Sitong’s concentric cables have formed a unique competitive advantage by virtue of their "power transmission + signal interaction" dual-function design. They have created benchmark application cases in smart grids, industrial manufacturing, new energy, and other emerging fields, becoming a key growth driver for the company’s international business.

Smart Grid & Industrial Monitoring: Precision & Reliability

• Zhengzhou 10kV Smart Grid Renovation Project: Sitong’s concentric cables serve as the core connection medium between distribution network terminals and the main control station. While providing stable power for smart meters, load controllers, and other terminal equipment, the cables synchronously transmit real-time operation data such as equipment voltage and current. This dual-transmission capability has increased the grid’s dispatching response speed by 30%, realizing the transition from "passive maintenance" to "predictive maintenance" of the power grid.
• Jiangsu Chemical Industrial Park Project: Aiming at the high-humidity, strong-corrosion environment of chemical plants, Sitong customized corrosion-resistant concentric cables for reactor temperature and pressure monitoring systems. The cables use special anti-corrosion outer sheaths and reinforced shielding layers, which not only resist chemical erosion but also ensure the accuracy of signal transmission. Since their commissioning two years ago, they have maintained a zero-fault record, providing a strong guarantee for the safe production of the park.

New Energy & Smart Agriculture: Data Empowering Added Value

• Qinghai 50MW Photovoltaic Power Station: In one of the largest photovoltaic projects in Northwest China, Sitong’s concentric cables are used to connect solar panel combiner boxes and inverters. While efficiently transmitting the generated electricity, the cables feed back key parameters such as photovoltaic module efficiency, surface temperature, and ambient light intensity to the central control system in real time. This data support enables the power station to adjust the angle of the panels and optimize the operation strategy in a timely manner, increasing annual power generation by about 5%.
• Hunan Smart Agricultural Park: The integration of concentric cables has promoted the intelligent upgrading of the park’s irrigation system. The cables not only supply power to water pumps and sprinkler equipment but also transmit data collected by soil moisture sensors, light sensors, and temperature sensors. The agricultural Internet of Things platform uses this data to automatically trigger irrigation operations, reducing manual management costs by 45% and ensuring the stable growth of cash crops such as strawberries and greenhouse vegetables.

Core Technical Advantages: Building Multi-Dimensional Product Barriers

The outstanding performance of Sitong’s concentric cables stems from its in-depth technical research and development:
1. Innovative Structural Design: The concentric conductor structure integrates power-carrying and signal-transmitting functions, reducing the number of cable laying by 50% in dual-demand scenarios, and lowering project construction costs.
2. Strong Anti-Interference Capability: The optimized multi-layer shielding layer design effectively isolates external electromagnetic interference, reducing the signal transmission error rate by 40% compared to traditional products—critical for precision equipment such as industrial sensors.
3. Excellent Environmental Adaptability: The use of weather-resistant and corrosion-resistant materials enables the cables to operate stably in outdoor, underground, coastal, and other complex environments, adapting to the diverse climate conditions of the global market.
4. 5G-Ready Supporting Capacity: The company’s supporting communication cables adopt high-purity copper cores and low-loss insulating materials, ensuring low latency (≤1ms) and high bandwidth for 5G signal transmission. They have been applied in multiple county-level digital rural construction projects, providing network support for rural smart agriculture and remote medical care.

Full-Process Quality Control: The Foundation of Global Trust

Quality is the core competitiveness of cable products, and it is also the cornerstone of Sitong Cable’s ability to strengthen cooperation with global partners. The company has established a strict full-process quality control system covering "raw material incoming inspection → in-production monitoring → finished product testing → after-sales tracking":
- Raw Material Control: Copper conductors, PVC insulation materials, and other core raw materials are purchased from internationally renowned suppliers and must pass 12 strict tests such as purity detection and tensile strength before entering the factory.
- Intelligent Production Monitoring: The production line is equipped with internationally advanced online monitoring equipment, which automatically detects the insulation thickness, conductor resistance, and other key indicators of power cables and concentric cables in real time, eliminating defective products at the source.
- Strict Finished Product Testing: Every batch of products undergoes voltage resistance testing (up to 3kV), insulation resistance testing, signal transmission performance testing, and other 8-item final inspections, ensuring that all indicators comply with IEC 60502-1, ANSI C119, and other international standards.

This rigorous quality management system has enabled Sitong Cable to obtain ISO 9001 quality management system certification, CE certification, and South American INMETRO certification, laying a solid foundation for its global market expansion.
