Windings. 10.1 The windings of the reactors shall be aluminum, without joints.
10.2 The clearance between adjacent turns shall be not less than 1/4 inch, unless approved by The Xxx Xxxx Co.
Windings. All cables, rods or conductors used for windings shall be of high quality and pure electrolytic copper. Conductor insulation will be made of high thermal stability paper resistant to aging, a varnish bath can be applied to improve mechanical resistance. The fully assembled winding and core assembly shall be vacuum dried to ensure moisture extraction and then impregnated and immersed in dielectric oil. h3. Tank The tank will be built with high-strength structural steel plates, reinforced with steel profiles. All openings that are necessary in the walls of the tank and in the cover, will be provided with flanges welded to the tank, prepared for the use elastic gaskets that do not deteriorate under the effect of the hot oil. Oil-resistant synthetic rubber gaskets will not be accepted. The tank shall be provided with two grounding plugs with their respective connectors located at the opposite ends of the bottom of the tank. It will also be provided with valves and accessories (the list is not limited). h4. Bushing insulators and terminal boxes Bushing insulators will be of the capacitor type. The porcelain used in the bushings must be homogeneous, free of cavities, protrusions, peels or cracks and must be impermeable to moisture. All parts of the bushings exposed to atmospheric action must be made of non-hygroscopic material. h5. Insulating oil The reactor will be supplied with its full insulation oil supply plus a reserve of at least 5% of the net volume. These supplies will be shipped separately in airtight steel containers. The reactor will be shipped without oil, instead it will be filled with nitrogen gas for transportation. The dielectric oil to be supplied will be refined mineral oil, with no inhibitory substances in its chemical composition and which must comply with the IEC 60354 and IEC 60296. h6. Current transformers Reactors will be supplied with current transformers built in the bushings, two cores, both for protection, in all windings and in the three phases. In addition, they will have current transformers for thermal image protection.
i) Serial Compensation System
Windings. All cables, busbars, or conductors used for the windings shall be made from high- quality, high-purity electrolytic copper. The conductor insulation shall be made from high thermal stability, age-resistant paper. The conductors may be lacquer-coated for better mechanical strength. The core and windings set, fully assembled, shall be vacuum-dried to guarantee moisture extraction, and then impregnated and immersed in dielectric oil.
Windings. All wires, busbars or conductors used for winding shall be made of high quality and purity electrolytic copper. The conductors shall be insulated with paper of high thermal stability and resistant to aging; however, a lacquer bath could be applied to improve the mechanical strength. The winding and core assembly, fully mounted, shall be vacuum dried to ensure extraction of moisture so it can be later impregnated and submersed in dielectric oil.

The conductor insulation will be made of highly thermally stable and resistant to aging paper. A coat of varnish may be applied to improve the mechanical strength. The windings and core set, completely assembled must be vacuum-dried to ensure extraction of moisture and after at it must be impregnated and immersed in dielectric oil. The power transformer should be provided with a gas analyzer built with remote monitoring equipment.

Windings a) All rotor windings, especially main lead to the first coil, end-windings, cross connections between coils, and leads to slip-rings or rotating rectifier assemblies are to be supported and protected to prevent displacement or damage by centrifugal force and be capable of 5000 stop/start operations for the remaining life of the power station.
b) The rotor windings are designed to withstand, without damage, the effects of a sudden interruption of full excitation current.
c) Rotor windings are to be constructed of silver-bearing copper so as to prevent harmful plastic distortion under operating conditions involving cyclic heating and cooling.
d) The rotor winding must be able of operating on barring gear for extended periods without adversely affecting the copper, slot insulation, interturn insulation or result in copper dusting.
