5. FAQ (Frequently Asked Questions)

Q1: What is the difference between prime power and standby power of YC4D80Z-D20 generator set in actual use?

The 44kW/55kVA prime power refers to the long-term continuous working power of the unit, supporting 24-hour uninterrupted power generation for daily main power supply scenarios such as field operations and remote area power supply. The 48kW/60kVA standby power is only for short-term emergency peak load during grid power failure or sudden load increase, and cannot operate continuously for a long time. For daily use, controlling the long-term operating load within 80% of prime power can reduce unit wear, lower failure probability and greatly extend the overall service life of the generator set.

Q2: What are the core advantages of the brushless self-excited alternator of this 60Hz Yuchai generator?

Different from traditional brushed alternators, the brushless self-excited alternator equipped on YC4D80Z-D20 has no carbon brush and slip ring wearing parts, eliminating regular replacement and maintenance work, which saves a lot of time and labor costs for daily operation. Cooperated with H-grade high-temperature insulation and AVR intelligent voltage regulation technology, it delivers more stable voltage and frequency output, stronger anti-interference ability, lower operation noise and failure rate. It is more suitable for long-term standby and high-load continuous power generation, and shows better stability in harsh working environments.

Q3: Can the YC4D80Z-D20 diesel generator adapt to high altitude and extreme temperature working conditions?

Yes, this unit has excellent all-weather environmental adaptability. It can achieve stable cold start at -25℃ ultra-low temperature, solving the difficult startup problem of ordinary generators in severe cold areas. It operates stably at an altitude of 2500 meters without power derating, fully meeting the power supply needs of plateau and mountain field operations. Meanwhile, the closed water cooling system ensures stable heat dissipation in 55℃ high-temperature environments, and the IP23 protection grade resists outdoor dust and rain splash erosion, adapting to various complex outdoor and industrial working conditions.
