In 2024, Suriname launched the "Deep Blue One" submarine fiber optic system construction project, a key infrastructure initiative aimed at improving the country’s coastal and offshore communication connectivity, supporting marine resource development, and bridging the digital divide between coastal and inland areas. As a core participant in this project, Dongguan Greater Wire & Cable Co., Ltd. provided customized electrical cable solutions, successfully addressing the client’s critical pain points with our UL-certified products, rich engineering experience, competitive pricing, and reliable quality. This case details how we supported the smooth progress of the Suriname Deep Blue One project, highlighting the application value of our XHHN-2, MC Cable, and PV Cable in marine utility projects, and demonstrating our strength as a trusted electrical cable exporter.
1. Urgent Needs and Pain Points of Suriname’s Marine Fiber Optic Project
The Deep Blue One submarine fiber optic system, located off the coast of Suriname, is a large-scale marine communication infrastructure project covering approximately 180 kilometers of submarine fiber optic lines, connecting 6 coastal towns and 3 offshore observation stations. The project, undertaken by a well-known local engineering company in Suriname, aimed to build a high-speed, stable communication network to support real-time data transmission for marine environmental monitoring, fishery management, and coastal emergency communication. However, the project team encountered multiple challenges in the selection of electrical cables, which directly affected the project’s progress and long-term operational stability.
The client’s core pain points were concentrated in four aspects. First, the submarine and coastal construction environment is extremely harsh—high humidity, strong salt spray corrosion, large temperature differences, and potential mechanical damage from marine organisms and seabed rocks require cables to have excellent corrosion resistance, water resistance, and mechanical strength. Second, as the project involves critical communication infrastructure, the client has strict requirements on cable safety and compliance, requiring all cables to hold UL certification to meet international safety standards and pass local regulatory inspections. Third, the project has a tight construction schedule and a fixed budget; the client needed high-quality cables at a competitive price to avoid cost overruns while ensuring construction progress. Fourth, the client lacked experience in selecting cables for large-scale marine projects and needed a supplier with professional technical support and rich similar project experience to provide one-stop solutions, from product selection to on-time delivery and after-sales guidance.
Before cooperating with us, the client had contacted several cable suppliers, but none could fully meet their needs. Some suppliers lacked UL certification, making their products unable to pass local regulatory inspections; others had no experience in marine utility projects and could not provide targeted product recommendations; a few suppliers offered high-quality products but at prices that exceeded the client’s budget, making cooperation unfeasible. At this critical juncture, the client found Dongguan Greater Wire & Cable Co., Ltd. through Google search, and after in-depth communication, decided to cooperate with us to solve the cable supply problem.
2. Tailored Cables for Marine Environmental Needs
After fully understanding the project’s requirements, construction environment, and client pain points, our professional team conducted in-depth research and designed a customized cable solution, focusing on three core cable types: XHHN-2, MC Cable, and PV Cable, each selected for its unique advantages to match the project’s specific scenarios. We also ensured that the solution fully integrated our core advantages, including UL certification, similar project experience, competitive pricing, and reliable quality, to comprehensively address the client’s concerns.
First, for the power supply lines of the submarine fiber optic junction boxes and coastal communication stations, we recommended XHHN-2 electrical cables, specifically the 12 AWG, 14 AWG, and 16 AWG sizes. The XHHN-2 cable is a high-performance cross-linked polyethylene (XLPE) insulated cable, which differs significantly from traditional THHN/THWN-2 cables. Unlike THHN/THWN-2 cables with thermoplastic PVC insulation (which may melt under high temperatures and emit toxic smoke when burned), the XHHN-2’s XLPE insulation is a thermoset material that undergoes a curing process, maintaining its shape and structure even under high temperatures (rated 90°C in both wet and dry conditions) and not emitting toxic smoke in case of fire. This makes it ideal for the harsh marine environment, where high humidity and potential fire risks require high safety and durability. Additionally, the XHHN-2 cable has excellent chemical resistance and salt spray corrosion resistance, effectively preventing damage from seawater and salt spray, ensuring long-term stable operation in marine environments. This is the key reason the client chose XHHN-2 over traditional cables—its superior performance in harsh environments directly addresses the client’s concern about cable durability.
Second, for the internal wiring of the offshore observation stations and fiber optic signal conversion rooms, we provided MC Cable (Metal-Clad Cable), including 10/3 AWG and 12/2 AWG sizes. The MC Cable is equipped with a lightweight aluminum interlocked armor and a sunlight-resistant PVC jacket, complying with UL 44 and1569 standards. Compared with ordinary non-armored cables, the MC Cable has stronger mechanical protection, effectively resisting mechanical damage from construction, marine organisms, and seabed rocks. It is also suitable for wet locations and direct burial applications, meeting the NEC 330.10(11) standard, which is perfectly adapted to the offshore observation stations’ outdoor and humid working environment. The client chose MC Cable because it integrates insulation, protection, and wiring functions, reducing installation complexity and improving construction efficiency, while its UL certification ensures compliance with local safety regulations.
Third, for the power supply system of the solar energy equipment supporting the coastal communication stations, we supplied PV Cable (Photovoltaic Cable) with specifications of 4mm², 6mm², and 10mm², rated for DC 1500V. The PV Cable is designed with halogen-free cross-linked insulation and护套, complying with IEC 62930:2017 standards, with excellent UV resistance, high and low temperature resistance, and aging resistance. In Suriname’s tropical coastal climate, where sunlight is strong and temperature differences are large, the PV Cable can maintain stable performance for a long time, avoiding insulation aging and power leakage caused by harsh weather. Compared with ordinary power cables, the PV Cable has lower electrical loss, improving the energy conversion efficiency of the solar power system, which aligns with the client’s demand for energy conservation and long-term stability.
Notably, this project also involved XHHW-2 electric cable utility projects supporting the onshore power distribution network connected to the submarine fiber optic system. The XHHW-2 cable, with its high heat resistance (125°C in dry conditions) and superior water resistance, was used in the onshore power distribution lines, ensuring stable power supply to the entire fiber optic system. Its UL certification and compliance with NEC standards further enhanced the overall safety and reliability of the project.
3. UL Certification and Strict Quality Control
For the Suriname Deep Blue One project, safety and compliance are the top priorities, and our UL certification and strict quality control system provided the client with full confidence. All three core cable types we supplied—XHHN-2, MC Cable, and PV Cable—have obtained UL certification, including UL 44 for XHHN-2 and MC Cable, and UL 4703 for PV Cable, ensuring that the products meet the strict safety standards of the United States and international markets, and can smoothly pass Suriname’s local regulatory inspections. As a globally recognized safety certification, UL certification verifies that our cables have passed rigorous tests in terms of fire performance, electrical characteristics, mechanical strength, and environmental adaptability.
In addition to UL certification, we have established a full-process quality control system to ensure the stability and reliability of each batch of cables. From the selection of raw materials, we only use high-quality XLPE insulation materials, oxygen-free copper conductors, and corrosion-resistant armor materials, and conduct strict inspections on raw material suppliers to ensure the quality of raw materials. During the production process, we adopt advanced production equipment and strict production processes, with professional technicians monitoring each production link in real time to avoid defects such as insulation gaps and conductor oxidation. After production, each batch of cables undergoes a series of tests, including insulation resistance test, voltage withstand test, mechanical strength test, and corrosion resistance test, and only products that pass all tests are allowed to leave the factory. This strict quality control system ensures that our cables can withstand the harsh marine environment and maintain stable performance for a long time, addressing the client’s concern about cable quality and safety.
Furthermore, our rich experience in undertaking similar marine and utility projects has provided additional safety assurance for the project. We have participated in multiple submarine fiber optic and coastal infrastructure projects in Southeast Asia and Latin America, accumulating valuable experience in product selection, installation guidance, and after-sales service. Our technical team can provide professional suggestions according to the specific needs of the project, helping the client avoid potential risks in cable selection and installation, and ensuring the safety and stability of the entire project.
4. On-Time Supply and Professional Technical Support
The Suriname Deep Blue One project had a tight construction schedule, requiring the cables to be delivered on time to avoid delaying the construction progress. After signing the cooperation agreement, we immediately arranged production, optimized the production schedule, and prioritized the production of cables for this project to ensure that the products were completed within the agreed time. Considering the long-distance transportation from China to Suriname, we chose a professional international logistics company with rich experience in exporting electrical cables, ensuring that the cables were properly packaged (using moisture-proof, shock-proof, and corrosion-proof packaging materials) to avoid damage during transportation. At the same time, we tracked the transportation process in real time, provided the client with transportation information and customs clearance documents in a timely manner, and helped the client complete customs clearance smoothly, ensuring that the cables arrived at the construction site on time.
In addition to on-time delivery, we also provided professional technical support throughout the project. Our technical team communicated with the client’s construction team in a timely manner, providing detailed product specifications, installation guidelines, and precautions, helping the construction team understand the performance and installation requirements of the cables. For the installation of MC Cable in offshore areas and PV Cable in solar power systems, our technical team provided remote guidance, solving problems encountered during installation in a timely manner. We also arranged on-site technical personnel to visit the construction site twice, conducting on-site inspections and guidance to ensure that the cables were installed correctly and in line with project requirements. This professional technical support solved the client’s lack of experience in marine cable installation, ensuring the smooth progress of the project.
