3 Coil Innovation Air-Core Reactors 50Hz Solutions, through Coil Innovation, is able to supply the complete range of air-core reactor products. Coil Innovation specialises in the design and manufacture of air-core dry-type reactors for transmission and distribution networks. Air-Core Reactors Air-core reactors are essentially a wound inductance utilising one or more windings in parallel. Insulated aluminium solid conductors or stranded cables are used, with the final coil being impregnated with epoxy resin and painted to provide the finished reactor. Depending on the application, air-core reactors can be supplied in stacked, side-by-side or triangular arrangements. The finished coils are mounted on station post insulators and (where necessary) additional steel structures. Air-core dry type reactors do not utilise an oil insulation system or an iron core. They are environmentally friendly and do not provide any fire hazard. They are essentially maintenance free. Applications Air-core reactors have a number of key applications in transmission and distribution networks: n Fault current limiting reactors n Load flow control / line balancing reactors n Inrush current limiting for capacitor banks reactors n Neutral earthing reactors n Harmonic filters reactors n Shunt reactors n Static VAR compensation reactors n DC smoothing reactors n Electric arc furnaces reactors n Line traps for PLC Coil Manufacturing Air-core reactor windings are manufactured either with one single layer or several layers in parallel. Rectangular aluminium solid conductors or stranded cables are used; these are insulated with high performance film insulation and woven tape. The windings are arranged radially with fibre-glass spacers that provide vertical ducts for convection cooling of the windings. Windings are completed by impregnating with epoxy resin to provide superior electrical properties and high resistance to weathering. All surfaces are finished by painting if necessary with UV resistant paint. In areas of heavy pollution, an additional silicone coating can be applied to eliminate the risk of surface tracking. Innovation in Coil Winding Technology Unlike traditional reactor manufacturing, Coil Innovation uses a winding method whereby the length of each winding layer is continuously monitored to allow fine adjustment of conductor dimensions. This results in extremely fine tolerance of the inductance; hence optimum current and temperature distribution within the individual parallel winding layers. This manufacturing precision ensures the longest life and design performance of the reactor. Low Noise Reactor Innovation The ever growing demand for electrical equipment with extremely low sound levels has prompted the development of very low noise reactors. Coil Innovations patented sound mitigation technology allows ultra low noise designs to be manufactured. Its state of the art sound measurement test laboratory is able to simulate operation at various loads and harmonic frequencies. brochures on air-core reactors from Coil Innovation please visit the 50Hz Solutions website:

4 MGC Moser Glaser RIP Bushings and Duresca Busbar 50Hz Solutions, through the Swiss company MGC Moser Glaser, supplies a range of products utilising their DURESCA resin impregnated paper (RIP) technology. MGC s product range includes custom designed insulated busbar, wall bushings, transformer bushings and custom designed bushings for special application such as retrofits. Resin Impregnated Paper (RIP) Technology Moser Glaser (MGC) invented the resin impregnated paper (RIP) technology in 1958 a process that is designed to insulate electrical conductors for bushings and busbars for HV and MV applications. The insulation lies directly on the aluminium or copper conductor and consists of wrapped paper dried under vacuum and impregnated with epoxy resin. Conductive grading layers are embedded in the insulation during the wrapping process to provide field control. The RIP technology provides an oil free/dry type bushing that can be created in short lengths for transformer and wall bushing applications, or up to 10m lengths for busbar systems. Transformer Bushings MGC is growing rapidly as a manufacturer of RIP condenser transformer bushings using directly bonded silicon rubber insulators with no filler between the bushing body and insulator. Bushings are available from 24kV up to 300kV rated voltage and 3150A rated current (soon to 550kV). The transformer bushings use MGC s Travesca RIP technology, ensuring fine grading of the insulating body and silicone rubber insulator for the outdoor (air) portion of the bushing. MGC specialises in like-for-like (retrofit) replacement of transformer bushings to existing transformers; the flange and critical dimensions of the existing bushings can be matched to provide a very cost effective means of extending the life of the transformer. Wall Bushings and Special Purpose Bushings Our range of wall bushings includes indoor-indoor, indoor-outdoor and outdoor-outdoor models for applications from 12kV up to 245kV and 6300A. The wall bushings use MGC s Duresca RIP technology, and for outdoor application include polymer or porcelain insulator sheds. A standard range of wall bushings meeting IEC requirements provides a cost effective solution for most applications. Alternative and custom designed bushings can meet unique site requirements such as specific flange/bolt hole designs, wall thickness considerations, current transformer requirements and terminal palm/pin requirements. We can also supply the current transformers if required. In addition to transformer bushing replacements, MGC can design special and retrofit bushings based on customer supplied specifications and drawings for various applications; for example we have supplied many hundred bushings to replace the old oil-air bushings in bulk oil circuit breakers Duresca Insulated Busbar MGC s RIP technology is also used to manufacture their DURESCA insulated busbar system up to 170kV rated voltage and >10,000A rated current. It is a fully insulated high voltage/high current busbar system that is custom designed for the electrical and mechanical characteristics of the application. The busbar is effectively a long condenser bushing and incorporates a corrugated polyamide or aluminium tube for mechanical and weather protection. The DURESCA busbar fastens directly to wall, floors and ceilings with metallic support structures and can be manufactured in lengths of up to 10 meters. The lengths of each busbar section are defined by site design, transportation limits, site installation constraints and the manufacturing process. Lengths are then joined within connection sleeves which incorporate flexible joints for expansion/measurement tolerances. brochures on bushings and busbar from MGC please visit the 50Hz Solutions website: The key feature of the busbar is its very small bending radii compared to cable (eg. 400mm for 1250A 145kV) which make it perfect for space constrained environments and switchgear interconnections. A full range of terminal palms and switchgear connection types, including air-insulated, plugins, and GIS are available.
