Cable Ladders

Cable ladders are designed to support high linear loads and to permit a higher ventilation in order to mantain a constant cable temperature inside, even with cable tray covers. For this reason, cable ladders are mainly suitable for energy cables installations.

Thermal Expansion of cable ladder parts: Our joints with crossed slots allow an even greater deviation between the elements, recovering any possible expansion without damages.

Electrical Continuity: The electrical continuity of ladder cable trays is guaranteed by the correct assembly of joints and/or the copper bonding jumper; for this purpose, properly marked grounding holes are made on the cable trays and related accessories.

Our Successful Projects

Energy

Taweelah RO Independent Water Project

The world’s largest sea water reverse osmosis desalination plant (RO), boasting a capacity of 200 MIGD (909,200 cubic meters of water per day). This plant surpasses the world’s current largest RO facility by 44% in terms of capacity. The Taweelah plant is poised to establish new benchmarks for water production efficiency and cost, thanks to its utilization of RO technology instead of thermal desalination.

New Hydrogen Production Unit – Porto Marghera

The project aims at implementing two hydrogen production lines for the Venice biorefinery in Porto Marghera. Its primary objective is to increase the availability of hydrogen at the biorefinery to fulfill the requirements of the EcofiningTM unit in terms of quality, quantity, and availability, all while optimizing energy efficiency. As part of a phased transition to producing decarbonized hydrogen, these units are designed to significantly reduce the emission of fossil CO2 into the atmosphere by utilizing biogenic charges recirculated by the EcofiningTM unit.

Luanda Refinery

The expansion and modernization initiative aims to significantly increase the refinery’s petrol production capacity, quadrupling it to 450 thousand tonnes per year. As a part of this project, the Combined Cycle has been revamped to utilize hydrogen generated by the new Platforming unit. Additionally, energy production has been optimized by recycling gas, resulting in a notable reduction in polluting emissions.
