FAQs
Can it adapt to the voltage and frequency requirements of different countries' power grids?
Yes, it can flexibly customize 50Hz/60Hz frequencies, with a voltage fluctuation range of ± 10%, which can meet the distribution network parameter requirements of different regions such as Southeast Asia, Africa, and Europe. At the same time, local certifications (such as CE, UL) can be provided.
How to ensure the sealing performance of equipment in cross-border transportation?
Before transportation, vacuum sealing treatment and shock-absorbing cushioning packaging should be carried out, equipped with transportation specific fixing devices to avoid deformation of the air box and damage to the sealing components. After arrival, on-site airtightness testing services should be provided to ensure the equipment performance is intact.
How to ensure overseas after-sales response and spare parts?
There are 12 service outlets on five continents worldwide, with remote response time for routine faults ≤ 24 hours. For complex faults, engineers can be dispatched for on-site repairs. At the same time, sufficient spare parts are stored in overseas warehouses with a supply cycle of ≤ 7 days.

Agricultural irrigation power distribution scenario in overseas countries: It is suitable for agricultural irrigation projects in tropical regions such as Southeast Asia and Africa. The equipment can withstand high temperature exposure, rainstorm and flood, and its anti salt fog and dust prevention design can cope with harsh field environment. The compact structure can be flexibly installed in simple distribution rooms in the field, providing stable power supply for irrigation pumps, water fertilizer integrated machines and other equipment. It is environmentally friendly and pollution-free, meeting the needs of local agricultural green development. At the same time, its low operation and maintenance characteristics are suitable for weak local operation and maintenance conditions.
Distribution scenario of foreign-funded enterprises in China factories: Balancing IEC international standards and domestic power supply regulations, perfectly adapting to the power supply needs of imported production equipment in foreign-funded factories, and stable operation without the need for installation of conversion devices. The environmentally friendly gas meets the green production standards of the enterprise headquarters, and the multilingual control panel is easy for foreign operation and maintenance personnel to operate. The intelligent remote diagnosis function can achieve real-time linkage between the headquarters and factory equipment status, which meets the refined and international management needs of foreign-funded enterprises.
Overseas port branch line distribution scenario: In response to the severe salt spray corrosion and large load fluctuations along the coast of overseas ports, multi-layer anti-corrosion coatings on equipment can effectively resist salt spray erosion, and stable arc extinguishing performance can cope with frequent start stop impacts of port loading and unloading machinery. Support remote control function, facilitate centralized operation and maintenance of ports, meet the requirements of international port green operation for environmental protection, and have seismic and impact resistant design to adapt to the vibration environment of port cargo loading and unloading, providing power for cranes, refrigerated storage, and navigation equipment.
