We offer vapor phase drying plant. To optimize the dielectric properties of transfomers insulatios vapour phase process drying are used. Initially technologies such as hot air drying technologies were used for drying of insulation. Quality requirement triggered the need the need for careful treatment in vacuum, hence the new trend of evolution of vapour phase drying of insulaon of power transformers. Basis of of treatment were relation of pressure of vapour, temperature and water content in paper insulatio. With this advance technology we optimizes heat transfer, insulation stress and process time. Vapour phase drying plant is used for heating, vacuum & impregnation of transformer & coils or other active part in an autoclave by means of solvent vapour. The process is carried out in an autoclave with the evaporator using the advance vapour phase drying process sequence i.e heating up phase with intermedaite pressure lowering phase, pressure reduction phase, fine vacuum phase and aeration. Vapour phase drying plant shall be used for vacuum drying and impregnation of power transformer, c.ts & p.ts etc the autoclave is loadedunloaded by mechanized trolley. All side autoclaves are heated by heating manifolds located iutside either by thermic fluied or by steam heating. A skid mounted compact type vacuum pumping system consists of combination of roots and rotary pumps with main and intermediate condensors used to creat cvacuum in the autoclave. The plant is operated by dedictaed dcsplc (computerzed) for proess optimization to operate and control the operation. The complete plant is "state of the art" latest design and

Significant numbers or indeed have exceeded there 40 years design life. 1.power transformers may be slowly moistened over the years or be quickly moistened when repairing some faults. 2. As paper moisture content rises the rate of ageing increases and dialectic strength falls , ultimately paper become brittle and fails. 3.decomposition product in transformer like paper, pressboard and wood in the cellulose de-polymerization is water which is store in the insulation and also in transformer oil. 10% of the weight of power transformers reduces dielectric margin, decreases partial-discharge inception voltage, debases insulation performance and increases the probability of unexpected failures. 4.the condition of the paper is indicated by the degree of polymerization or ‘dp. The higher the dp, the longer the length of the cellulose hydrocarbon chain and the better the condition of the paper. New paper typically has a dp value of around 1800. As the cellulose ages, it breaks down into smaller lengths i.e. The dp value falls. Critical dp values are around 200-300, 5. If a transformer is to have extended service life then internally generated moisture and free fibres must be continuously removed. 6. The best method of removing water from a power transformer is to undertake a mobile vapour phase dry-out at the transformer manufacturer using hot kerosene at 150-180oc to remove oil and water from the insulating papers.

Enlisted amid one of the renowned business organizations, we are willingly betrothed in bringing forward an extensive spectrum of Vacuum Drying Autoclave. Developed making use of finest class basic material along with modern machinery, these are extensively checked on a number of grounds before final shipment. In addition to this, these are offered by us in finest quality packing material to retain their flawlessness. Atmospheric drying is carried out for transformers with a working voltage of 33kv. In higher voltage class transformers thicker and longer insulation parts are used. Ordinary air drying will not be able to remove moisture contained in this insulation within a reasonable time. Therefore vacuum drying is used for such transformers. Vacuum drying also accelerates the drying speed. at normal atmospheric pressure boiling point of water is 100 deg c. But in vacuum water boils at very low temperatures. Following details are given to get an idea of relation between pressure and boiling point of water. pressure boiling point 760mm/hg 100 deg c 4mm/hg 1. 24 deg c 1mm/hg -19 deg c   vacuum drying autoclave simply placing transformer in autoclave vessel under vacuum will not remove moisture form that. For evaporating water into steam latent heat of water is to be supplied. when transformer put in to the autoclave for drying heat energy is transferred to transformer via convection and radiation. Compared to convection energy transfer by radiation is very low. During vacuum drying as air is sucked out there will not be any transfer of heat by convection. This necessitates heating by hot air of sufficient duration, before vacuum drying in the autoclave vessel by externally either by thermic fluid heating system/electric heating system/steam heating by means of radiator coils inside autoclave or limpets welded outside the autoclave..
