FACILITY
We take pride in our reputation for excellent customer service, quality products, and innovative solutions.
Design
A highly innovative and experienced design team makes sure the international standards are adhered to throughout the process.
Design Capabilities & Facilities
Our team have the capability to implement customer requirements over the entire range of a project, from basic design to detailed engineering. The team has proven that through various product design development to cater for the requirement and specifications of Oman authorities. All designed products has been tested inhouse and subjected to complete type tests to meet international standards and local specifications.
Advanced Design Activities
Our design team is working with 2D/3D drawings with latest version of Autodesk Inventor software, which generates error free accurate drawings, Pictorial view of each part before manufacturing the products, presentations show the way to assemble the components and automation of drawing preparations.
Short Circuit Design Capabilities
Short circuit proven designs to verify Electrical and Thermal Test and to prove that transformers meet customer requirements as per Latest International Standards.
Manufacturing
The core employs a mitred step-lap design ensuring minimum noise and loss level
The Core
Each transformer core is produced by using interleaved laminations of cold rolled, grain orientated, low loss electrical sheet steel conforming to BSEN 10107 and other international standards. The core employs a mitred step-lap design ensuring minimum noise and loss levels with uniform flux distribution throughout the magnetic circuit.
Windings & Insulation
All windings are manufactured to exacting standards in order to maintain strict dimensional tolerances. Clamping to a pre-determined load pressure during manufacture ensures that each winding is able to withstand the excessive axial forces which may result from external and short-circuit events.
All principal components of insulation are prefabricated from electrical grade insulating board and are pre-shrunk to ensure electrical and mechanical stability throughout the temperatures found in operational service.
The completed core-coil assembly is dried in a PLC controlled vacuum drying chamber
Each core-coil assembly is rigidly braced using steel frames, distributing the axial clamping forces around the entire circumference of the windings. Optimum dielectric strength is achieved via processing in accordance with rigorous in-house quality procedures.
Tanking
The completed core-coil assembly is dried in a PLC controlled vacuum drying oven. The dried active parts are fitted into the transformer tank and oil is filled under vacuum through a filtration machine.
Final Assembly
When the tanking process is completed all accessories are fitted.
- Bushings (Oil to Oil, Oil to SF6, Oil to Air Condenser, Porcelain, Plug-in type, Monoblock)
- Conservator with hydro compensator (Air bag)
- Maintenance free breathers
- Hydran/Callisto online gas monitoring devices
- Other customer specific fittings/instruments
After the final assembly process is completed the oil is filtered again and allowed to settle before the transformer is moved to the test bay.
