Poly wrapped winding wire commonly known as “Submersible Copper Winding Wire”. The copper conductor is wrapped with thin polyester film and Biaxial oriented poly propylene (BOPP) films. These are are used in submersible pumps motors of all sizes for domestic and industrial application.
Corona Resistant Winding Wires are used in Inverter drives & Stator Windings. In inverter driven motors, excessive surges and voltage peaks during speed variation, creates corona discharge in the stator windings, which induce extra thermal stress on the insulation, causing excessive thermal ageing there by weakening and even decomposing of the insulation.
Fine and Ultrafine Enamelled Copper Wires are mainly used in Small Transformers, Relays, Ignition Coils, Transformers & Small Motors. The enamelled wire properties governing proper selection not only require consideration of the end use conditions but system compatibility and ease of use in production.
Glass fibre-lapped conductors (bare or enamelled) are very suitable for windings of electric motor stators, generators, special transformers and high voltage motors, heavy magnet coils etc. The glass in glass fibre conductor may be applied in woven tape form or as a continuous fibre.
Nylon top coat wires can be used in high speed windings for armature coils of home appliances, power tools, auto coiling machines for switch gears miniature coils in electronics etc. Nylon top coat exhibits a smooth and tough, slippery surface of top layer of insulation, thus, reducing chances of insulation damage and failures related to mechanical abuse of the thin insulation layer.
Crepe Kraft Paper Insulated Copper Cables are mainly used as an insulation in oil cooled transformers, current transformers of type IMB, CT, CVT as leads and shields. The plain kraft papers are wrapped in a number of layers around conductors, to acquire the needed insulation strength.
Self Bonding enamelled wires have an outer layer of bondable material which is usually thermoplastic and bonds the wires surfaces with each other once heated to the bonding temperature of the outer layer. Bondable wires can be used in power tools armature coils, electronics, miniature coils, TV yoke coils, continuous-transposed conductors etc.
Enamel film insulated rectangular copper conductors are known as enamelled copper strips. Super Enameled Copper Strips are used in various types of transformers.
Enamelled winding wire is a film insulated copper (or aluminium) electrical conductor used in form of coil windings in motors, transformers, generators and other electromagnetic equipments.
A unique product for small transformers with three layer extruded coatings of high performance polymer resins that gives excellent dielectric properties to this type of winding wires

RR Fan’s High-Volume Low Speed (HVLS) fan is an Air Circulating device which has a Large Diameter in comparison to a conventional Ceiling fan. It is available in varied sizes ranging from 8 to 24 feet. These fans are generally ceiling mounted although some are Pole mounted too. The key highlight of these fans is that they move slowly by distributing large amounts of air at low rotational speed, hence they are known as High Volume Low Speed (HVLS) Fans.
Permanent Magnet Synchronous Motorised HVLS Fan series from RR has been conceptualized and developed at our in-house R&D centre. It has a light and stylish design with the fan blades made from aviation grade aluminum that makes them stronger and more efficient. The winglets help in reducing air resistance and noise, reaching optimal silent performance at low speeds. Our PMSM HVLS Fan is certified with ISO 9001:2015 and made using only world class industrial grade components and spare parts of the highest quality. We ensure the most efficient and reliable fan for you to use.
