Flat Submersible Cable
Samflex Submersible Cable ensures trouble-free operation even in the harshest underwater conditions. Our 3-core flat cables are engineered with precision-annealed copper conductors, carefully bunched and drawn for durability. Each conductor is insulated using a specially formulated PVC compound, then assembled in a flat parallel position.
The outer sheath is made of high-grade, water-impervious PVC, resistant to grease, oil, abrasion, and environmental stress. Rigorous testing at every stage—from raw materials to finished product—ensures Samflex cables meet stringent performance and safety standards, making them a trusted choice for submersible pump and motor connectivity.
Every cable undergoes stringent quality testing, ensuring protection against indefinite immersion in water under specified conditions, making it the preferred choice for submersible pump applications.
