    СММur-1L mobile oil plant


    The СММur-1L continues the excellent functionality of this series of equipment, but is designed to be more compact and economical.

    The СММur-1L purifies electrical insulation oil1Insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. with viscosity2The viscosity of a fluid is a measure of its resistance to deformation at a given rate. below 70 cSt at 50o, removing water and particulate matter.

    This device can heat oil-filled electrical equipment with hot transformer oil and evacuate air from vacuum3Vacuum is space devoid of matter. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. systems.

    The unit ensures oil purification4Oil purification removes oil contaminants in order to prolong oil service life. according to class -/14/12 from initial class -/18/16 (contaminant content by weight less than 0.004%) after multiple passes of the product through the filters5Filter is a device which separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass..

    The СММur-1L is used in the course of commissioning, repairs and operation of oil-filled high voltage systems (power transformers6A transformer is a static electrical device that transfers electrical energy between two or more circuits., high voltage switches7Switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. etc).
