Clean and retighten electrical switchboards

Maintenance of electrical switchboards increases their reliability, minimising the damage by allowing a reduction of costs.
They say the best practices that the paintings should remain in a good state of repair and cleaning. And should be cleaned periodically using dielectric solvents and ecological products. Cleaning the paintings should be made by aspiration, and not blow compressed air, thus avoiding due to pressure from the air, dust or foreign objects, to settle on the system or in active parts, causing malfunction. Dust can facilitate disruption during the dielectric rigidity test.
