FAQs
What are the core differences between customized diesel generator sets for telecom base stations and standard diesel generator sets?
The core difference lies in adapting to the special working conditions and requirements of telecom base stations. Customized models are designed for scenarios such as unattended operation, all-weather running, high requirements for voltage and frequency stability, and shock and temperature resistance. They can be integrated with remote monitoring modules, ATS (Automatic Transfer Switch) and noise reduction devices, and feature a more compact size to fit the limited space of base stations. Standard diesel generator sets are mostly of universal design and cannot meet the high reliability and customized functional needs of base stations.
How to choose your new power generation equipment?
Many customers need to consider the technical and economic feasibility of diesel power generation solutions. Usually the diesel genset is combined with the external large power grid, and the energy supply complements each other, which can improve the reliability and flexibility of the entire system.
To find a cost-effective, technically reliable and more environmentally friendly power generation solution, we recommend that you consider the following important factors when choosing a power generation equipment:
- The most important thing is the installation cost. Diesel genset solutions offer very competitive installation costs compared to other power generation systems, with a limited footprint for a single kilowatt project.
- Power generation efficiency. The power generation efficiency of diesel gensets directly affects the economy of the project. PowerLink diesel gensets are efficient and offer a high value.
- Manufacturing and commissioning time. PowerLink diesel gensets usually take 3 to 6 months from production time plus construction and commissioning time. Your cash on delivery time will be shorter if you have it in stock.
- Modular installation solution. Considering that the equipment is ultimately delivered safely to the installation site, the modular structure makes project installation easier and commissioning simpler and faster.
- Another very important factor in determining the choice of power generation equipment: the operating expenses associated with the equipment. These aspects need to be considered: service intervals, spare parts costs, downtime during maintenance, and the entire working cycle of the equipment before the overhaul. Based on our long experience, we offer multi-year service contracts for PowerLink gensets. This can help reduce the need for spare parts and can predict service times in advance, reducing operating costs throughout the engine’s working life.
- Help you select the most suitable equipment through the load analysis of the project. PowerLink’s wide range of diesel engines (5 to 3250KVA) will help you find the right solution for you.
- The surrounding environmental conditions will have an impact on the use of the equipment, thus affecting its actual power output capacity. In other words, in some cases, your power output may be much lower than the rated power. If you plan to operate equipment at high temperatures and/or altitudes significantly above sea level, be aware of this factor.
Where can I buy PowerLink products?
- We have dealers in more than 100 countries worldwide, and you can contact local dealers to purchase products. In areas without dealers, you can contact our offices directly, and our sales experts will provide a one-on-one service with you.
