HV Overhead Line Works

High Voltage Overhead line Installation- 11 to 400KV

 Our well qualified and experienced engineers have a thorough knowledge of protection schemes, commissioning procedures and equipment options in the Utilities, Construction and Engineering industries. This includes testing protection & control schemes, switchgear and SCADA in the UAE. They are fully conversant with most modern electrical practices and Standards for in-stallation and testing regimes.
EMC provides design, procurement, survey, construction and logistics man-agement services for overhead lines from 11kV up to 400 kV for transmission and distribution networks.
At EMC we fully understand the requirements and demands of the power industry, hence we offer our cli-ents unmatched innovative solutions delivered safely and to their precise specification. The experience and depth of projects undertaken by us leaves us well experienced to deliver complex and large scale projects.

We offer:

• Wooden & Tower pole design
• Refurbishment and maintenance of existing overhead lines
• Condition assessment and route survey.
• Make temporary or permanent access for new line construction.
• Foundation design, construction and management
• Conductor tension stringing.
