Product Overview
Tinned copper is primarily engineered for protection against oxidation and corrosion. In environments where copper has long-term exposure to water and humidity, oxygen combines with the metal to form brittle copper oxide, weakening the metal bonds and reducing conductivity. Tekla Energy tinned bunched copper conductors prevent accelerated corrosion in wet and contaminated settings, safeguarding against premature cable failure.
