- Power Transformers
- Overview: Power transformers are critical components in primary distribution networks, designed to receive high-voltage electricity and step it down to lower voltages suitable for further distribution or direct customer use. These transformers play a key role in the efficient transmission of electrical power over long distances.
- Product Range & Specifications: Al-Ahleia manufactures robust power transformers with ratings ranging from 2500 KVA to 50,000 KVA, specifically engineered for up to and including 132 KV class systems. These transformers are designed to handle the demands of primary distribution networks, ensuring the safe and reliable transfer of electricity to secondary systems.
- Distribution Transformers (Single / Dual Ratio)
- Overview: Distribution transformers are essential for the secondary distribution of electrical power, ensuring reliable energy delivery to end-users. These transformers are designed to step down voltage for safe and efficient use in various industrial and residential applications.
- Product Range & Specifications: Al-Ahleia specializes in manufacturing high-quality distribution transformers ranging from 50 KVA to 2500 KVA. These transformers are equipped with cable boxes on both the high-voltage (HV) and low-voltage (LV) sides as per project requirements, ensuring ease of connection to secondary distribution networks.
- Pole-Mounted Transformers: In addition to conventional ground-mounted distribution transformers, Al-Ahleia offers pole-mounted transformers with HV and LV outdoor bushings / with cable boxes as per project requirements. These are particularly suitable for applications in remote areas such as oil well supply, supporting joint operations and providing critical power infrastructure in challenging environments.
- Unit distribution substation transformers: Our unit distribution substation transformers are engineered for durability, safety, and minimal maintenance. They undergo rigorous type testing to meet international standards, ensuring optimal performance in any environment. Customized to meet specific voltage and capacity requirements, Al-Ahleia transformers are the ideal solution for reliable power distribution across diverse networks.
- Hermetically Sealed Transformers
- Overview: Hermetically sealed transformers are engineered to provide maximum protection against external environmental factors, including moisture and dust, by fully sealing the transformer from the outside air. This makes them ideal for applications in harsh or remote environments.
- Design & Functionality: In smaller hermetically sealed transformers, a dry air cushion is used to accommodate the expansion of transformer oil caused by temperature fluctuations. For larger units, a rubber bag is incorporated in the conservator to absorb oil expansion and contraction, effectively isolating the oil from atmospheric contamination.
- Customization Options: Al-Ahleia offers hermetically sealed transformers with custom designs based on specific customer requirements, ensuring that each solution meets the operational and environmental needs of our clients.
- Earthing Transformers
- Overview: Earthing transformers, also known as zig-zag winding transformers, are specialized units designed to provide an earth reference point for ungrounded electrical systems. These transformers are also instrumental in controlling harmonic currents, making them crucial for the stability and safety of electrical grids.
- Design & Application: Typically, earthing transformers feature a primary winding but no secondary winding. However, some configurations may include an auxiliary winding, typically used for lighting loads. These transformers ensure the proper functioning of ungrounded electrical systems by maintaining a stable earth reference.
- Custom Specifications: Al-Ahleia manufactures earthing transformers with short-time current ratings of up to 10 and 30 seconds. Additionally, they can be supplied with auxiliary windings. We encourage customers to specify their requirements for short-time current ratings and zero-phase sequence impedance to ensure optimal performance.
- Regulating Transformers
- Overview: Regulating transformers are designed to provide precise voltage regulation in systems where the input voltage fluctuates, ensuring a stable and reliable output voltage. These transformers are vital for applications that require consistent power quality despite variations in the input supply.
- Functionality: These transformers either offer a broad, variable range of output voltage while maintaining a constant input voltage, or they can provide a constant output voltage from a variable input. This versatility makes them ideal for industries where voltage fluctuations are common.
- Customization: Al-Ahleia manufactures regulating transformers to meet specific customer needs, ensuring that the voltage regulation range aligns perfectly with operational requirements.
- Auto Transformers
- Overview: Auto transformers are unique in that they use a single winding for both the primary and secondary circuits. This design reduces the overall cost of the transformer while maintaining efficiency, as the primary and secondary windings share part of the same winding.
- Design & Advantages: The use of a single winding in auto transformers allows for a more compact and cost-effective solution, making them ideal for applications where cost reduction and space efficiency are key considerations.
- Customization Options: Al-Ahleia provides auto transformers with various ratings and specifications based on the specific needs of our international clients. Each transformer is customized to deliver optimal performance for the customer’s unique application.
- Converter Transformers
- Overview: Converter transformers are specialized transformers designed to work with thyristor-based converters, typically used in motor control centers or variable speed drives. These transformers are crucial for ensuring smooth power conversion and voltage regulation in sophisticated industrial applications.
- Functionality: Al-Ahleia manufactures converter transformers that are engineered to meet the exacting standards of modern power electronics, particularly in high-performance motor control and variable-speed drive systems.
- Customization: Our converter transformers are available in a wide range of ratings, tailored to customer specifications to meet the precise demands of industrial power conversion systems.
- Furnace Transformers
- Overview: Furnace transformers are specifically designed to support high-power applications such as arc furnaces and induction furnaces, where high currents and specific voltage levels are required for efficient operation.
- Design & Application: These transformers are built to withstand the demanding conditions of furnace operations, ensuring reliable and stable power supply. Customers can specify the incoming voltage, as well as the required outgoing voltages, ensuring that each transformer is perfectly suited to the unique needs of the furnace application.
- Customization Options: Al-Ahleia offers furnace transformers with various tapping options, including both constant and variable KVA ratings. We work closely with clients to determine the precise voltage and KVA specifications, ensuring optimal performance and energy efficiency.
