Power Plants
In the recent years, the use of combined cycle power plant has been increased, and MACTRO team is working in some of them from the beginning and during the installation until the start-up, and by providing the required parts, standard and equivalent, it makes supplying parts our daily Business.
Our team looks forward to provide you with a professional consulting in the following products:
Control valves are used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "set point" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
High and Low pressure valves are designed to open and relieve excess pressure, then immediately close, preventing any loss of flow of fluid after normal conditions have been restored, Pressure Relief Valves are designed and made to act as a safety measure in the pressurized gas or liquid system.
Corten A and Corten B a chemical compositions of steel, when utilized unprotected, exhibits increased resistance to atmospheric corrosion compared to unalloyed steels, this is because it forms a protective layer on its surface under the influence of the weather.

Oil Sparator: An Oil-Water Separator is a unit designed to separate large volumes of oil from water within wastewater effluents like chemical plants, oil refineries, and other industrial sources.
Burner Heads and Burner in special design, Bearing.
Power Substation
A substation is a part of an electrical generation, transmission, and distribution system, Substations transform voltage from high to low, or the reverse, or perform any of several other important functions between the generating station and consumer, electric power may flow through several substations at different voltage levels.
Our team will guide you with your project from the planning phase until the start up. For spare parts, we have our special Lists and we are pleased to assist you in finding the suitable parts for you from our list.
We deliver spare parts during the maintenance period and beyond, such as:
Medium and High Voltage Circuit Breaker: A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit, its basic function is to detect a fault condition and interrupt current flow.
Protection Relay: A relay is automatic device which senses an abnormal condition of electrical circuit and closes its contacts. These contacts in turns close and complete the circuit breaker trip coil circuit hence make the circuit breaker tripped for disconnecting the faulty portion of the electrical circuit from rest of the healthy circuit.
Capacitor Banks: A Capacitor Bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy, the resulting bank is then used to counteract or correct a power factor lag or phase shift in an alternative current (AC) power supply, they can also be used in a direct current (DC) power supply to increase the ripple current capacity of the power supply or to increase the overall amount of stored energy.
Control Systems: Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer, generally substations are unattended, relying on SCADA (Supervisory Control and Data Acquisition) for remote supervision and control.A control system is a device, or set of devices, that manages, commands, directs or regulates the behavior of other devices or systems, industrial control systems are used in industrial production for controlling equipment or machines. There are two common classes of control systems, open loop control systems and closed loop control systems, in open loop control systems output is generated based on inputs,in closed loop control systems current output is taken into consideration and corrections are made based on feedback, a closed loop system is also called a feedback control system.
The planning, implementation and construction of substations is our specialty, we also supply spare parts for steel and cement factories.
We design and deliver modern Substations (20 kV, 66 kV, 230 kV and 400 kV) according to the International Standards.
Steel & Pipes
We supply pipes in all standards and non-standard material grades, sizes and forms. We supply U-pipes, Pipe bends, Finned tubes, Fittings, for a special orders or not mentioned standards, please contact us and we will gladly assist you in finding the best suitable Pipes for you.
Heat Exchanger
A Heat Exchanger is a piece of equipment built for efficient heat transfer from one medium to another. A Heat Exchanger is relatively straightforward product in almost all industries, however, it requires maintenance and checkup on a regular basis, and with our know how to, and years of experience, we are able to improve the Effectiveness and the Efficiency of each type of any Heat Exchanger dramatically, and when it comes to advice, then you are at the right place with us,whether you are an engineering consultant or an end user, we are specialized in the reconstruction of the Heat Exchanger, and also we can deliver a complete new Heat Exchanger, all necessary tests are carried out (such as Hydro Test), and the certificate is according to EN 10204/3.1.
Motors and Cables
Electrical Motor is an electrical machine that converts electrical energy into mechanical energy, the reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator. In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor, in certain applications, such as in the transportation industry with traction motors, electric motors can operate in both motoring and generating or braking modes to also produce electrical energy from mechanical energy. Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators, small motors may be found in electric watches, general-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use, the largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts, electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.
High Voltage Cable (HV cable) is a cable used for electric power transmission at high voltage, the cable includes a conductor and insulation, and is suitable for being run underground or underwater, this is in contrast to a conductor, which does not have insulation, high-voltage cables of differing types have a variety of applications in instruments, ignition systems, and AC and DC power transmission, in all applications, the insulation of the cable must not deteriorate due to the high-voltage stress, ozone produced by electric discharges in air, or tracking, the cable system must prevent contact of the high-voltage conductor with other objects or persons, and must contain and control leakage current, cable joints and terminals must be designed to control the high-voltage stress to prevent breakdown of the insulation. Often a high-voltage cable will have a metallic shield layer over the insulation, connected to the ground and designed to equalize the dielectric stress on the insulation layer. High-voltage cables may be any length, with relatively short cables used in apparatus, longer cables run within buildings or as buried cables in an industrial plant or for power distribution, and the longest cables often run as submarine cables under the ocean for power transmission. Medium-voltage cables are commonly used in mobile substation equipment, for distribution of power in industrial settings and in mining to supply power to drills, shovels, haulers, etc., These cables often come in standard voltages, including 5,000; 8,000; 15,000; 25,000; and 35,000 Volts. A common application for medium-voltage cables is in maintenance and repairs, utilities personnel use mobile workstations to provide scheduled downtime maintenance for substations or to conduct repairs due to damage caused by a storm, for example.
