Universal Metals Pvt Ltd has introduced high-performance Submersible Copper Wires through technical collaboration with Japan. Our company specializes in manufacturing premium winding wires for electric water submersible motors (EWSM) and electric oil submersible pumps (EOSP). Our reputation is built on solid technical expertise, advanced technology, and reliable product quality.
Submersible Copper Wires are specifically engineered for use with submersible pumps in deep wells. These wires must be highly waterproof since they remain primarily submerged during operation. To ensure maximum reliability, our Submersible Copper Wires are insulated with high-quality resins from Altana Chemise, Germany.
Our product range includes the ‘Standard’ German Thin ‘Cross Linked 90C’ covering copper wires, designed for electric oil submersible pumps. This product is highly regarded in assembly plants and large oil fields throughout Pakistan.
Submersible Copper Wires from Universal Metals are exceptionally reliable. Rigorous testing in France has proven that SONA submersible copper wires possess excellent mechanical and electrical strength, with insulation performance that is more than sufficient for demanding applications.
Our experience and extensive research enable us to select only premium brands of high-grade Copper Rod, ensuring superior quality throughout our product line. To meet exacting quality standards, we use copper with the lowest levels of impurities. Strict control of operating parameters during production ensures that conductors achieve optimum annealing, resulting in the preferred texture for optimal electrical conductivity, tensile strength, elongation, and springiness.
Continuous testing during manufacture ensures the integrity of surface finish, quality, purity, and gauge. Our fully equipped technical department conducts all specialist testing and inspection at both the point of manufacture and in our laboratory.
Performance Testing
Typical tests include tangent delta measurements to achieve optimum performance of our Submersible Copper Wires, ensuring:
