Medelec has a philosophy to offer complete engineering solutions for electrical distribution substations. Our committed and experience team of engineers ensures optimal mechanical and electrical designs to meet the customer requirements through the use of the latest software and engineering techniques to prepare the necessary design documentation. Clients can thereby develop an idea from concept, design, prototype, testing and product validation prior to manufacturing with the shortest lead time and minimal costs. Factory manufactured products are built to meet high quality standards and tested to verify the original designs. Substation installation is monitored and supervised by experienced personnel to ensure professional work practices. Product training and after sales service are provided to support customers.

MECHANICAL DESIGN
• Custom sheet metal enclosure design.• Internal layout design to provide best fit of
components and equipment for intended purpose.• Assistance in the development of new products for
specific applications.• Retrofitting of steel parts in existing enclosures.• Use of sophisticated 3D modelling software to
facilitate visualisation before production while reducing prototype time.
• Preparation of the necessary documentation including part assembly and development drawings.
• Preparation of CAD/CAM programs for production.• Generation of a prototype unit for new designs.• Provide rendered views of the product
for presentations.
