Core service

Construction of Transmission Lines

Transmission line construction is one of our core services. We build overhead lines from 33 kV to 765 kV and handle the complete scope of work:

  1. Complete engineering and design
  2. Route survey and profile preparation
  3. Soil investigation
  4. Design and construction of foundations
  5. Tower erection
  6. Stringing of conductor, earth wire & OPGW
  7. Testing and commissioning

Every project is led by experienced project managers and engineers, backed by our own design, fabrication and galvanising facilities.

Manufacturing

Fabrication

Our imported CNC machines (Ficep and Messer) are supported by hydraulic presses, machine tools, jigs and fixtures, so bent sections are formed without distortion. Ground and overhead cranes keep material handling fast and safe.

Galvanising

Galvanising is one of our key strengths. Our semi-automatic, gas-fired hot-dip galvanising plant by Protherm (UK) has a heat pumping unit, flame-proof flow heater, self-proportioning burner, centrifugal blowers and a heat-resistant cover, with pickling, rinsing, pre-fluxing and quenching tanks and a zinc kettle.

A pre-heating chamber dries and heats the steel evenly for a smooth finish and a uniform zinc coating, and an automatic digital controller keeps the furnace at the correct temperature.
