英国采购需求：发电机组、发电机、柴油发电机、柴油发电机、便携式发电机、隔音柴油发电机

I'm in the market for a reliable generator that I intend to ship to Africa. Ideally, I'm looking for a unit that's not only durable but also efficient, as it will be used in various conditions. If you have different models available, I'd appreciate it if you could provide me with details on their specifications, performance metrics, and any optional features that might enhance usability. Additionally, I want to understand the logistics involved, such as shipping options, lead times, and any associated costs. It would be great to know about the warranty and after-sales support, as I want to ensure long-term reliability. Please send me any relevant catalogs or product brochures so I can review your offerings in more detail. Looking forward to your prompt response!
