Dingbo Power, a professional diesel generator set manufacturer, is pleased to present our 1200KW 1500KVA silent diesel generator set, engineered to deliver stable and reliable power supply with low-noise operation. As an authorized supporting manufacturer for world-famous engine brands (Cummins, Perkins, Deutz, Weichai, Shangchai, Yuchai) and generator brands (Stamford, Leroy-Somer), we ensure the quality, stability and durability of the core components of each generator set.
This 1200KW 1500KVA silent diesel generator set is designed to meet the practical high-power supply needs of various scenarios. It adopts a rational structural design, with a silent cabinet made of 2mm galvanized steel—this material boasts excellent corrosion resistance, rust resistance and color fastness, ensuring long-term stable operation even in harsh working environments. The interior of the silent cabinet is filled with 5cm sound-absorbing cotton, which effectively reduces the unit’s operating noise to 75 decibels at 7 meters, meeting the noise requirements of most noise-sensitive scenarios.
Equipped with an 8-hour fuel tank at the bottom, the generator set can operate continuously for 8 hours under rated load, reducing the trouble of frequent refueling and ensuring uninterrupted power supply when needed. We adhere to a practical and customer-oriented principle: our professional team can provide personalized configuration recommendations based on the customer’s specific use scenarios, budget and power demand, ensuring the generator set perfectly matches actual application needs and achieves optimal cost performance.

The advantages of 1500kVA diesel generator:
Guaranteed Core Component Quality: As an authorized supporting manufacturer of renowned brands such as Cummins, Perkins, Deutz, Weichai, Shangchai, Yuchai, Stamford and Leroy-Somer, all core components of our generator sets are original and authentic. This fundamentally ensures the reliability, stability and service life of the unit, avoiding risks caused by inferior or refurbished components.
Practical Low-Noise Performance: The silent cabinet is made of 2mm galvanized steel, which is corrosion-resistant, rust-proof and not easy to fade. The 5cm sound-absorbing cotton inside the cabinet effectively isolates and absorbs noise, reducing the unit’s noise to 75 decibels at 7 meters. It should be noted that a silent generator set does not mean "no noise"; instead, it controls noise within a reasonable range through scientific noise reduction measures, complying with environmental noise standards and avoiding noise pollution complaints.
User-Friendly Design: The built-in 8-hour fuel tank at the bottom supports continuous operation under rated load, which is suitable for scenarios requiring short-term uninterrupted high-power supply and reduces the frequency of manual refueling. The overall structure is compact and reasonable, facilitating transportation, installation and daily maintenance.
Customizable Configurations: We do not adopt a one-size-fits-all model. According to the customer’s actual use scenarios (such as indoor/outdoor, noise-sensitive or not), budget and specific power requirements, we can recommend suitable engine, generator and auxiliary component configurations. This ensures the unit is practical and cost-effective, avoiding unnecessary waste of resources.
Reliable Manufacturer Strength: As a professional diesel generator set manufacturer, we have rich production experience and a strict quality control system. All products comply with relevant national and international standards (such as GB/T 2820.10-2002, ISO8528-2005), and each unit undergoes strict testing before leaving the factory to ensure it meets practical use requirements.
