Product description

Product Overview

YS type of OFWF cooler approaches to heat exchange by forcedly cycling the transformer oil and forcedly cycling water. The product is a type of tubular cooler which consists of a tubular cooler, an oil pump, a control box, a base, a pressure gauge, valves, pipes and etc. The expansion technology is applied to the connection between tubes and side plates which is able to eliminate leakage. There is a diversion chamber between outer pipe which contains oil and inner tube which contains water. The leaking alarm is set in this diversion chamber to prevent the mixing of oil and water due to the leakage on inner tube. This type of OFWF cooler is applied to hydroelectric power station, generator set of nuclear power plant, underground power substation, pumped storage power station and other special area.
