POWER GENERATION, TRANSMISSION AND DISTRIBUTION EQUIPMENT

We have supplied power equipment for the oil and gas industries, chemical and petrochemical projects, mining and metallurgy processes and many more.

We are able to provide the equipment required for the full range of the energy business, from power generation using conventional and renewable energy sources, as well as for local transmission and distribution. We have experience in both start-up projects, new construction, and renewal of old networks, as well as providing what is required to continue the high-quality spare parts that must be available in all power plants and transmission networks.

As a company with good experience in the region, we are well aware of the requirements of the old and old power plants that depend on the vast hydrocarbon resources in the region, and we often use oil, gas and coal as the source of energy, but we are also well aware of the region’s move to start peaceful nuclear power generation, the important move extremely towards renewable energy sources, with solar energy leading the way in most of the Gulf region, and other energy sources such as wind, hydro-dynamics, and geo thermal mass and biomass play an increasingly important role as the world moves to a more sustainable future and decarbonized world.

We provide the equipment needed to build and maintain power generation, including turbines and generators of all types and capacities, that can operate in power plants using fossil fuels (including gas and oil), hydroelectric and nuclear power and increasingly with renewable energy sources played by solar energy.

We work with several transmission and distribution networks, providing their requirements for towers and shafts, through a wide range of needed transformers, as well as cables and substations, and other requirements such as lubricants and coolants.

We also provide power electronics devices including diodes, transistors, trios, hybrids and inverters (AC / DC, DC / DC, DC / AC, AC / AC)

Our supply also includes the range of electric motors needed by the industry, such as rotating magnetic field, rotating induction motor, linear induction motor, synchronous motor, direct current motor, stepper motor and single phase motor.

Looking to the future, we are ready to provide the needs of smart grids and smart network management, as well as the requirements of building smart homes. We are also working to support the increasing shift in the automotive industry away from hydrocarbons to electric cars and hybrid vehicles

2. TRANSMISSION

Transformer

Transformer’s function is to increase or decrease the voltage. Transmission starts from the power generation at a high level, and when the electric power is delivered to the load centers, the voltage is reduced for safe distribution over cities. Finally, the voltage is further reduced for household distribution at 100–240 V, depending on the various standards worldwide. The transformers’ capability allows the transmission and distribution of massive amounts of power in modern extensive power grids.

  • Transmission transformers are connected to both ends of the transmission line. At the generating power plants, the transformer steps up the voltage of the generators to very high levels (220 kV–1 MV) so that the current can be reduced substantially.
  • Distribution transformers are installed in distribution substations near the load centers. They reduce the output voltage of the transmission transformers to a lower level of 5–220 kV.
  • Service transformers are located near customers’ loads and lower the distribution voltage to the household level. They are normally mounted on power poles, placed inside vaults, or installed inside large buildings.

Circuit transformers are small transformers extensively used in power supplies and electronic circuits where the household voltage is stepped down to the circuit voltage level of a few volts. Other applications include impedance matching, filters and electrical isolation.

Transformer types

  • Multi-winding transformers which can have multiple secondary windings to provide different voltage levels to different loads.
  • Autotransformer which have its primary and secondary windings connected in series, and can be built to provide adjustable output voltage.

Autotransformer with adjustable voltage

  • Three-Phase Transformer can be constructed of a three-legged core when the primary and secondary windings of each phase are placed on the same leg of the core. Three-phase transformers can be connected wye–wye (Y–Y), or delta-delta (Δ–Δ), or wye-delta (Y–Δ).

A.2.2 Transformer bank

A transformer bank is two or three single-phase transformers connected as a three-phase transformer. These transformer banks are often used in distribution systems

Transformer banks: Single-phase transformer; Two transformer bank; Three transformer bank.

Power transformers require cooling for their core and coils, as the internal power loss is dissipated in ambient air to keep the temperature rise within the allowable limit set by the insulation material used in the construction.

The temperature rise can be as high as 180˚ in some dry-type transformers used indoors and as low as 55˚C in oil-immersed transformers widely used on land. In the increasing order of better cooling and compact size for the same kilovolt-ampere rating, the oil-filled transformer cooling classes are as follows:

  • OA oil–air self-cooled by natural convection and radiation
  • FA forced air cooled by fans
  • FOA forced oil–air cooled by oil pumps
  • OW oil–water cooled by water tubes or hollow conductors

Transmission lines, high-voltage tower

Distribution lines, low-voltage towers and poles

Most of the commercial and industrial plants have direct access to the distribution network, and they use their own transformers to step down the voltage to the levels needed by their various equipment.

In residential areas, utilities install transformers to reduce the distribution line voltage to any value between 100 and 240 V, depending on the standard of the country.

Power cables (conductors), fiber-optic cables and accessories

The power industry uses several types of cables; the most common ones are:

  • All aluminumconductors (AAC): This conductor has one or more strands of aluminum alloy without reinforcement strands. AAC is used when the span between towers is short (urban areas). In coastal areas, where corrosion is a problem, AAC conductors are used.
  • Aluminum conductors steel reinforced (ACSR): To increase the strength of the aluminum conductors, the ACSR has steel strands at its core surrounded by one or more layers of aluminum strands. The steel of the core is often galvanized steel (zinc coated). The ACSR are used when the span between towers is long. Even though the steel is galvanized, it can still be corroded over a period of time, especially in coastal areas.
  • All aluminum alloy conductors (AAAC): This is an alloy conductor made of aluminum, magnesium, and silicon.

We supply all kinds of cables – high voltage and low voltage, single and three phase, along with all accessories.

Bundled cable (conductor)

Very-high-voltage transmission lines have their cables split into sub-cables which are bonded together electrically, but are separated from each other by cable spacers which are repeated every few meters.

Static (shield) wire

Most transmission lines need protection from lightening and build-up of static electricity, which is done by one or two thin wires installed at the top of the towers, known as static, shield wire, or overhead ground wire (OHGW).

Picture caption: The two thin wires, suspended from the top of the tower, between the more visible bundled lines, are the static shield wires.

Substations

The substation is where the voltage is adjusted, circuits are switched, system is monitored, and equipment is protected. A typical substation includes

  • Transformers
  • Switching equipment
  • Protection equipment
  • Measuring devices
  • Control systems

A substation steps up or steps down the voltage of the incoming power. It includes:

  • Potential transformer – to measure the incoming current
  • Disconnecting switch – to isolate a section of the substation when needed
  • Circuit breaker – to open the circuit when faults occur
  • Current transformer – to measure the line current of the high-voltage side
  • Surge arrester – to dissipate any lightning or surge transients from damaging the transformer

Control center

  • System control Centre’s protect the entire network from being damaged due to the failure of any of its components or equipment. They also ensure that the network is operating effectively and economically to ensure the best rates to the customers. Besides the extensive monitoring, control engineers continuously evaluate the operation of the system, predict the future demand, and establish favorable energy trade conditions between utilities. These functions require the use of sophisticated algorithms that optimize the operation of the power system.
