Profile: Liquid Evolution specializes in offering environmentally friendly care products. Our core and windings are manufactured with materials that meet all specifications necessary for oil immersed transformers. Each transformer is pot tested to 5000 VDC for 1 minute before installation. Transformer winding is baked and braced to handle short circuit conditions without causing rupture of windows. Transformer steel is of the highest grade M4 material and all windings are copper & splice free. The oil cooled rectifiers are designed to run continuously at maximum duty cycle, while still offering dependability under the most severe conditions. Every rectifier is custom built. We also offer patented range of corrosion resistant products. Oversized reflective lenses are available in red and green for low light working areas. Our step iron range of products offers the latest in manufacturing techniques using BC-66 polypropylene and a solid steel core (16mm). These are manufactured and tested according to several international standards. They are used by various water authorities. Our manhole step iron features impact strength, usability in a wide range of temperatures, electrical insulation capability, precision molding properties & dimensional stability, low moisture absorption, and weather resistance.
