• User-friendly operation interface and maintenance space.
• Provide clear Chinese/English/French/Portuguese operation documents and maintenance manuals.

5. Flexibly respond to diverse application scenarios

• The product range covers a wide range:
• Box-type step-up substation: integrated medium-voltage switchgear, transformer, low-voltage cabinet and monitoring, pre-installed design, especially suitable for large-scale ground power stations (hundreds of kW to several MW level), shorten the on-site construction period.
• Photovoltaic dry-type transformers: flame retardant, maintenance-free, environmentally friendly, ideal for industrial and commercial rooftops, distributed power stations and small and medium-sized ground power stations.
• Photovoltaic oil-immersed transformer: good heat dissipation, strong overload capacity, more competitive price, suitable for large-scale projects (especially in extreme high temperature areas).
• Customization capability: Voltage level (such as 11kV, 33kV), capacity, protection level, interface mode, etc. can be flexibly customized according to project requirements.

Ⅲ. The key to success: go beyond the localization support of the device

In Africa, excellent localization services are the other half of a project's success.

1. Localized team with quick response:
• Set up offices or service centers in priority countries/regions.
• Equipped with local technical support engineers and service teams.
• 24/7 technical support in local languages.
• Establish and deliver on strict on-site response time commitments.
2. Localized Supply Chain & Spare Parts Network:
• Establish or cooperate in the establishment of local warehouses to store critical spare parts.
• Establish long-term strategic cooperation with local high-quality channel partners.
3. Professional Training & Knowledge Transfer:
• Provide comprehensive technical training for equipment operation, maintenance, and fault diagnosis for local customers, operation and maintenance providers, and installation teams.
• Training materials are available (multilingual).
• Supporting the development and capacity building of local technical talents.
4. Financing & Solution Support:
• Explore working with financial institutions to provide flexible financial leasing or procurement solutions.
• Provide a one-stop solution covering consulting, design, equipment supply, installation supervision, commissioning and operation and maintenance support.
