Resin saving single or multiple insert vessels with individual filling and level monitoring. Resin saving bottom piece extension for armature shaft. Compressed air system to feed oil-free filtered and dried air during pressurization. Vacuum System Quality vacuum pumps and accessories. Filter Filter on return resin line. Introduction Good insulation as well as protection from ambient conditions is vital for electrical equipment. Impregnation under vacuum using various resins and varnishes is the best solution for this purpose. Typical applications are electromagnetic coils, small transformers, instrument transformers, chokes, sintered bushes and similar products. For applications such as large motors and generators, high voltage transformers, special transformers, etc., it is required to apply pressure after impregnation. Main Components IMPREGNATION CHAMBER A vacuum tight vessel with bolt-clamp or boltless quick clamping flanges can be provided. The mechanism can be manual or hydraulically actuated. This is possible can be offered with a heatingcooling jacket or a limpet coil. Safety pressure release valves are provided.

In order to obtain void-free epoxy castings with low partial discharge and good du-electric strength suitable for use at high voltage it is necessary, among other things, to mix the resin & pre-dried filler well, to de-aerate it by vacuum and finally to pour it, also in vacuum.

The mixing chamber with circular cone-shaped bottom is heated with an oil jacket, the temperature being measured and controlled continuously. The temperature of the wall is hence uniform. A stirrer with baffle rotating at the correct speed which gives shearing action causes thorough resin filler mixing. The agitation exposes all the mix to vacuum& thus degassing is thorough. The mixing paddle drive is with 3 phase motor & reduction gear. The shaft seal is robust rotary seal with tapered roller bearings. The pouring valve is made of P.T.F.E. (Teflon) & this makes cleaning easy. Trap is used to very effective stop abrasive filler particles from entering & ruining the vacuum pump.

Water-cooled trap is provided for preventing volatile hardeners from entering the vacuum pump. Pouring chamber can be heated or unheated as required. Rotary turntable with vacuum-tight rotary seal or chain & sprocket driven trolley or rails allows the moulds to be positioned below the pouring spout without breaking vacuum.

Epoxy mixing & de-aerating plant: Medium size epoxy vacuum mixing plant for use in the laboratories of a progressive Electrical Manufacturer can handle from 5 kg to 200 kg of Resin-filler gardner mix. It is very versatile being able to handle solid or liquid resins hot or cold processing. Temperatures fro 160oC to room temperature are possible. A vacuum of 1 torr is easily obtained. the use of the plant enables void-free castings to be obtained.
