The Fenhar Manufacturer provides engineered insulation materials and custom fabrication solutions for a wide range of power generation equipment, including steam, hydro, and wind generators. With decades of experience, we specialize in high-performance insulation components for generator systems, ensuring reliability, efficiency, and extended service life. Our offerings include rotor and stator insulation, exciter components, and auxiliary parts, all tailored to meet the specific demands of the power generation industry. Whether for turbine, hydro, or wind generators, our solutions are designed to optimize performance and minimize downtime.

Turbine generators are vital components in power generation, particularly for steam, gas, and hydropower stations. The rotor, spinning at high speeds, creates substantial centrifugal forces, placing extreme demands on insulation materials. To withstand these forces and maintain operational efficiency, specialized insulation is crucial.
Key Insulation Components:

• Rotor Insulation Kits: These kits include a variety of components designed to protect the rotor during high-speed operations. Components include turn-to-turn insulation, vented and non-vented insulation, and compound ventilated creepage blocks.
• Stator Insulation: The stator is critical for power generation. Insulating the stator helps to maintain power output and prevents electrical failures. Key components include wedges, slot fillers, and top/bottom packing.
• Radial & Axial Blocking: These are used to provide structural integrity, minimizing vibration and wear during rotor operation. Materials such as glass epoxy and polyester are used for these critical blocking components.
• Exciter Insulation: This component ensures the efficient generation of direct current (DC) to power the rotor's magnetic field.

Material Options:
Glass Epoxy (NEMA G-10 & G-11): Offers high thermal resistance and mechanical strength for rotor and stator insulation.
Polyester (NEMA GPO-1): Ideal for rotor blocking and insulating components.
RotoGuard: A specialized material for turn-to-turn insulation and rotor slot liners.

• Rotor Pole Collars and V-Blocks: These are essential for maintaining rotor stability and insulation. Materials such as glass epoxy and enhanced polyester are used to prevent degradation from moisture exposure.
• Stator Insulation: Hydro stators need high-quality insulation for wedges, fillers, and ripple springs to ensure consistent electrical performance.
• Side Filler & Ripple Springs: These components support the structural alignment and help prevent short circuits by insulating between different parts of the stator.

Wind generators require insulation materials that can withstand variable environmental conditions, from high winds to temperature fluctuations. The materials must be flexible, durable, and capable of withstanding both electrical and mechanical stresses.
Key Insulation Components:

• Magnetic & Non-Magnetic Wedges: These are used to insulate and secure the wind generator’s stator. Magnetic wedges are vital for the electrical components, while non-magnetic wedges are used in areas where magnetic fields are not necessary.
• Topsticks and Barriers: These components provide additional insulation for the wind generator’s stator and rotor, protecting the internal electrical parts.
• Slit Coil Insulation: This flexible material is used to protect coil windings in the generator’s stator from environmental damage and electrical breakdown.
• Formed Slot Liners: Custom-fabricated slot liners are used to insulate the wind generator’s rotor and stator slots, preventing electrical short circuits and enhancing performance.

Material Options:
Glass Epoxy (NEMA G-10, G-11): Ideal for ensuring long-term stability and resistance to environmental stresses in wind power generation systems.
Flexible Papers & Films: Used for insulation in areas requiring high flexibility and environmental resistance.
Magnetic & Non-Magnetic Materials: Tailored to suit the unique electrical and mechanical needs of wind generators.

Gen sets, or generator sets, are used in a wide range of applications that require highly specialized insulation solutions. These systems often need components that can handle specific operational conditions, such as extreme temperatures or high vibration. Tailored insulation materials are used for parts like stator wedges, slot insulation, and other vital components. The need for precision fabrication ensures that these components fit perfectly within the gen set system, providing the necessary protection and insulation.

For specialty generators, key insulation components include stator wedges, slot insulation, and seals and gaskets. Stator wedges are custom-fabricated to prevent electrical leakage and maintain the stability of the stator. Slot insulation plays a vital role in optimizing electrical performance and preventing short circuits. Seals and gaskets, often made from elastomeric compounds, provide airtight and moisture-proof seals, ensuring the overall integrity and reliability of the generator.

The material selection for gen sets and specialty generators is based on the specific operational requirements. Materials like Glass Epoxy and Polyester are common choices for stator insulation, offering high thermal resistance and mechanical strength. Additionally, Elastomeric Materials are used for seals and gaskets, ensuring durability under high-pressure conditions and extreme temperatures. By offering tailored solutions, the Fenhar meets the unique needs of different industries, providing reliable and long-lasting performance for gen sets and specialty generators.
