HV And EHV Electrical System

HV And EHV Electrical System

Began in year 1991, PESTECH started its core business in the provision of comprehensive power system engineering and technical solutions for the design, procurement and installation of high voltage (“HV”) and Extra HV (“EHV”) substations, for local and international markets.

Over the years, the segment had built track records in constructing Air Insulated (“AIS”) Substation and Gas Insulated (“GIS”) Substations up to 500kV locally and across the regions. We have excellent project references with both utilities and private owners in Malaysia, Cambodia, Philippines, Sri Lanka, Papua New Guinea, Kyrgyzstan, Iraq, Ghana and Ivory Coast.

Our project execution is steered by an in-house engineering, construction and commissioning team to ensure that our delivery meets customers’ requirements and expectations. Our team is fully equipped with competencies such as design optimisation, multidisciplinary engineering implementation and interfacing in compliance with relevant international standards and electrical safety requirements. The wealth of collective knowledge and skills of our employees is vital for PESTECH to continue expanding its footprints in the power industry at the home front and regionally.

Aligned with the global call for business sustainability, we are adopting the modular pre-cast method in our substation projects to improve the work efficiency and reduce wastage during construction. The deployment of pre-cast construction method helps to reduce material wastage, minimises environmental impact and reduces the construction time for better project delivery.
