Many people associate high-end industrial parks with underground cables and fully enclosed utility tunnels, believing there shouldn’t be a single overhead wire. However, the reality is quite the opposite—an increasing number of advanced manufacturing parks, science and technology innovation bases, and green industrial parks are “smartly” using TST CABLE’s high-quality overhead cable system, ensuring power supply reliability while also considering cost efficiency and future flexibility.
The key is not “haphazardly strung bare wires,” but rather a modern overhead solution that is “aesthetically pleasing, intelligent, and highly reliable,” achieving a balance between safety, economy, and aesthetics.
I. Why Do High-End Parks Use TST CABLE Overhead Cables? Three Practical Reasons
Controllable Costs, More Efficient Investment: The cost per kilometer of underground cables + integrated utility tunnels exceeds 8 million yuan, while a high-quality overhead system only costs 2-3 million yuan, saving over 60%. For parks spanning several square kilometers, this money can be invested in R&D or talent acquisition.
Short construction cycle, early production for enterprises: Overhead lines can be energized in 1-2 months, while underground utility tunnels often take more than six months. For chip factories and biopharmaceutical companies urgently needing to start production, “time is cash flow.”
Flexible expansion, adapting to industry iteration: Future additions like data centers, hydrogen fuel stations, and high-power charging piles? Overhead lines can be expanded at any time without “road excavation,” avoiding disruption to enterprise production.
✅ Core concept: High-end industrial parks pursue not “invisible power lines,” but “invisible risks and visible efficiency.”
II. How can high-end industrial parks achieve a “high-end feel” with overhead cables?
✅ 1. Full insulation + exquisite pole and tower design: 1kV or 10kV cross-linked polyethylene (XLPE) insulated overhead cables eliminate the risk of electric shock and short circuits; Pole and tower designs integrate with antique steel columns and landscape lighting poles, even hiding them in green belts; Conductor colors are customized in dark gray, dark green, or matte black, visually “blending into the environment.” 🌳 Case Study: An AI industrial park in Suzhou Industrial Park uses poles integrated with 5G micro base stations and LED lighting, resembling modern sculptures from afar but revealing the true power infrastructure up close.
✅ 2. Multi-Pole Integration for Efficient Space Power, communication, monitoring, and streetlights share composite poles, reducing the number of poles by 70%; Layered cable laying ensures physical isolation between strong and weak currents, preventing signal interference; 20% redundant channel space is reserved to support future smart park upgrades.
📡 Results: The park’s roads are clean and tidy, with clear maintenance access, meeting the aesthetic standards of a “smart city.”
✅ 3. Intelligent Monitoring for Highly Reliable Power Supply Fault indicators, temperature sensors, and partial discharge monitoring terminals are installed on overhead lines; Data is integrated into the park’s energy management platform, enabling: Automatic fault location (accuracy ±50 meters); Load forecasting and dynamic voltage regulation; Real-time alarms for lightning strikes/external damage.
⚙️ Value: A semiconductor industrial park, through its intelligent overhead power line system, reduced its average annual power outage time from 4 hours to less than 8 minutes, meeting the requirements of the ISO 50001 energy management system.
✅ 4. Green Integration: Supporting Zero-Carbon Park Goals
Overhead lines are prioritized for connection to rooftop photovoltaic systems, energy storage stations, and V2G charging piles;
Low-loss conductors (such as aluminum alloy cores) and energy-saving fittings are used, reducing line losses by 3-5%;
Space is reserved at the top of the towers for future installation of small wind turbines or photovoltaic panels.
🌱 Trend: The Shanghai Zhangjiang Science City New Area explicitly requires that newly constructed overhead power lines must be compatible with distributed energy access and have carbon flow metering capabilities.
III. Typical Application Scenarios
Scenario | Solution | Advantages
R&D Office Area Periphery | Landscaped overhead insulated cable + multi-functional pole | Aesthetically pleasing, low-cost, rapid deployment
Factory Power Inlet | Self-supporting 10kV insulated cable directly into the workshop | Avoids complex underground conduit construction
Temporary Incubation Base | Detachable overhead system | Quick recycling and reuse after project completion
Park Edge Expansion Area | Primarily overhead + underground in the core area | Tiered investment, precisely matching needs
IV. Industry Trends: Overhead ≠ Low-end, but “Intelligent Light Infrastructure”
“Invisible Overhead” Emerges: Utilizing building facades, corridors, sound barriers, and other structures to attach cables, achieving “zero poles”;
Digital Twin Integration: Overhead line BIM models are linked with the park’s CIM platform for full lifecycle management;
Domestic High-end Substitution: Companies like TST CABLE and TST SEAL have launched weather-resistant, flame-retardant, low-smoke halogen-free overhead cables, with performance comparable to leading international brands.
Rationally Choose Truly “High-end” Overhead Cables
Power planning for high-end industrial parks has long surpassed mere “vanity projects.” Whether or not to use overhead cables depends not on their form, but on the scenario, cost, reliability, and future flexibility. When a meticulously designed overhead line can guarantee 99.999% power availability for a chip factory while saving the company millions in investment, it is the most “high-end” choice.
The smart parks of the future don’t need “invisible wires,” they only need every kilowatt-hour of electricity to be safe, efficient, and sustainable. Modern overhead cables, with their understated yet powerful presence, are becoming a crucial support for this goal.
