- Bonded Maintenance in Hainan (China): Why Are Used Generator Sets More Cost-Effective Than Brand New Ones? 2026-05-19 In the field of power equipment procurement, enterprises often face a choice: spend a large amount of money on a brand new generator set, or buy a professionally refurbished used unit for much less. The price of a used unit is typically 30–50% of a new one, but many people worry about quality issues. The bonded maintenance policy in China's Hainan Free Trade Port has made the refurbishment and repair of used generator sets more standardized and less expensive. The following nine aspects explain why used generator sets can be a more cost-effective choice.
- How Does Bonded Maintenance in Hainan (China) Simultaneously Serve the Maintenance Needs of Both Diesel and Natural Gas Generator Sets? 2026-05-08 In the actual operation of power plants, diesel generator sets and natural gas generator sets are two common types of backup power and peak-shaving equipment. Their working principles are similar, but they differ in fuel type, combustion characteristics, and maintenance focus. The bonded maintenance policy in China's Hainan Free Trade Port provides practical support for the maintenance of both types of equipment. The following sections explain the maintenance characteristics and technical points of each from the perspective of comparing the two types of equipment.
- How Does Bonded Maintenance in Hainan (China) Support Power Plants in Full-Process Management from Daily Maintenance to Emergency Fault Handling? 2026-04-28 Diesel generators in power plants are not equipment that runs every day, but their reliability directly affects the power safety of the entire plant. From daily servicing to deep overhauls, from fault diagnosis to performance verification, each stage has its own technical specifications. The bonded maintenance policy in China's Hainan Free Trade Port provides tariff exemptions and expedited customs clearance for the imported components involved in these stages. The following six aspects explain how power plants can achieve full-process management of diesel generators.
- How Does Bonded Maintenance in Hainan (China) Accompany a Diesel Generator Through the Entire Process from Arrival to Overhaul? 2026-04-28 When a new diesel generator set is delivered to a power plant and commissioned, it enters a long lifecycle from that day onward. This lifecycle goes through four stages: break-in period, stable operation period, performance degradation period, and overhaul decision period. Each stage has different maintenance focuses and technical requirements. The bonded maintenance policy in China's Hainan Free Trade Port plays a key role in the latter half of this lifecycle. The following sections explain this process in chronological order.
- How Does Bonded Maintenance in Hainan (China) Simultaneously Serve the Maintenance Needs of Both Diesel Engines and Generator Sets? 2026-04-28 In the field of power equipment, diesel engines and generator sets are two different but closely related types of equipment. Diesel engines are responsible for generating power, and generator sets are responsible for converting that power into electrical energy. Their maintenance focuses are different, their fault manifestations are different, and their repair methods are different. The bonded maintenance policy in China's Hainan Free Trade Port provides practical support for the maintenance of both types of equipment. The following sections explain from the perspective of comparing the two types of equipment.
- What Practical Problems Can the Bonded Maintenance Policy in Hainan (China) Solve for Enterprises in Maintaining Their Diesel Generators? 2026-04-28 The bonded maintenance policy in China's Hainan Free Trade Park has two core benefits: tariff exemption on imported repair parts and deposit exemption on the entry and exit of overseas equipment. These two provisions may sound simple, but for enterprises that own imported diesel generator sets, marine engines, and gas turbines, they solve real, tangible problems. The following seven aspects explain how the policy affects enterprise equipment maintenance decisions.
