Electrical Insulating Oil
DESCRIPTION AND USE
Hydrochem EIO is an electrical insulating oil that provides cooling, insulating, arc quenching, and cleaning properties while meeting the requirements of an ASTM C 3487 Type II fluid.
Hydrochem EIO is a fully inhibited Type II oil, which provides outstanding performance in transformers, circuit breakers, switches, and capacitors.
Hydrochem EIO is designed for use as an insulating medium in multi-circuit junction boxes to protect wiring and other metal components from corrosive agents.
Hydrochem EIO provides a fluid transfer medium for chlorine gas that is produced during the cathodic protection process. Chlorine byproducts travel from the anode site, through the wiring/insulation, and into the junction boxes. Without the insulating property of Hydrochem EIO, the chlorine gas reacts with oxygen and severely corrodes the wirings and connections, often leading to mechanical failure after only 6 months.
Hydrochem EIO will provide protection for 2-3 years.
Hydrochem EIO is designed to be used with CPT’s Cathodic Protection Junction Box Model RE-1.
