I'm looking for a reliable supplier for 4 core submersible cables. The purpose is to use them in various submerged applications, so I need cables that are durable and resistant to moisture and other environmental factors. It would be great to know the specifications you offer—such as voltage rating, current capacity, and insulation material. Additionally, I'm interested in your pricing, lead times for production, and the minimum order quantities. If you have product certifications or test reports, please share those as well. I'm keen on establishing a long-term partnership with a factory that can meet our quality standards and delivery requirements. Looking forward to your detailed response!
