Paper covering complies with class 105°C insulation is known for its excellent behavior in moist environment. That is why paper covered conductors best suited for oil-filled transformers and switchgears. The thickness of covering & the number of paper layers can be varied to suit the specific requirement. The properties of conductor are determined by the thermal, chemical & mechanical properties of the various paper types. Temp. Class:105? Type of Insulation : Kraft Paper
N o m ex C o v e r e d Ro u n d & Re c t . Flat Copper & Aluminium Wire Nomex covering corresponds to class H insulation is mainly used in the construction of condensers and capacitors. Main application of it is in shielding of cables in high temp. environments (200°C) such as dry type transformers,military and aerospace cables. Nomex covered conductors are more effective in condition where temperature resistance and dielectric strength requirements are high. Temp. Class:200? Type of Insulation: Nomex Paper

Kapton (Brand Name of DuPont’s Polymide Film) is the condensation product of an aromatic tetra basic acid and an aromatic diamine. It has no melting point, is infusible and self-extinguishing (does not support combustion). Kapton (Polymide Film) Covered Wires offers a wide range of applications in the construction of motors (specially in traction motors), aerospace equipments and nuclear power stations. It provides insulation with high electrical, thermal and mechanical properties over a temperature range of -196°C to +250°C. It provides higher Break Down Voltage (more than 8 KV BDV) as well as Temperature Class (220 °C) as compare with other insulated conductors. Insulating materials in traction motors have to withstand high temperatures and frequent changes of load and temperature. Standard materials applied for conductor insulation in Traction Motor application is polyimide film. It has excellent chemical resistance; there are no known organic solvents for the film. Kapton does not melt or burn as it has the highest flammability rating. The outstanding properties of Kapton permit it to be used at both high and low temperature extremes where other organic polymeric materials would not be functional. Kapton gives conductors space saving, which ultimately yields more power without increasing motor size. Kapton provides exceptional overload protection and long motor life, even in the most demanding applications and environments. Temp. Class:220? Type of Insulation : Kapton / Apical(Polymide Film)(50%, 66% Overlapping)

Mica paper consists of tiny platelets of mica that are made into a paper. This paper is extremely fragile and requires a carrier to render it usable, hence the polyester film. With respect to corona & thermal resistance requirements, Mica has shown itself to be the most suitable insulating material. Its application is mainly in high voltage rotating machines due to its superior resistance to corona and it is therefore obvious to use it also as conductor insulation in inverter driven motors. Temp. Class:220? Type of Insulation: Epoxy /Glass Mica
F i b r e G l a s s C o v e r e d Ro u n d & Re c t . Flat Copper & Aluminium Wire The Glass in Fibre Glass Conductor may be applied in woven tape form or as a continuous fibre. It has proved to be an efficient insulation providing coil winders with higher thermal stability, adequate electrical properties and good resistance to abrasion after varnishing. The glass is bonded with a varnish for dielectric strength to improve mechanical properties. Fibre Glass lapped conductors (bare or enamelled) are very suitable for windings of electric motor stators, generators, special transformers and high voltage motors. In general this insulation can be applied where high mechanical strength and high insulation properties are required. It exhibits a very high degree of mechanical and thermal stability. Temp. Class:F 155? ，H 180? ，C 200? Type of Insulation : Single /Double Layer of Glass Fibre & Impregnated with Class F 155? ，H 180? ，C 200? Varnish

The Diamond dotted Paper is to be used in oil-immersed transformers for the insulation between of coils. On the insulation layer, there is a layer dotted epoxy resin that will be changed with high temperature change that is to be called as felt. It is a kind of material with inertia, dry and no conglutination at normal temperature (below 30? ), The Diamond Dotted Paper (DDP)will make the electric conductor forever felt up as a hard unit under the high temperature by its internal latency substance. When the temperature is rising up to 90? , The Diamond Pattern Paper (DDP)begins one-off thaw and then one-off solidification. When to keep the temperature at 90? for 90 minutes, the epoxy resin would paste on neighboring cable and paper safely. The felt intensity is as high as to 70psl at 100? .(The value at least is equal to 0.450Mpa) (IEC standard)
