24KV Dry Type Transformer

SARAH Electric not only produces durable 24KV Dry Type Transformers, but also designs and manufactures lightning arresters, drop out fuses (fuses), surge protection devices (SPDs) for composite insulators, isolating switches, fuses and fuse devices, metal enclosures, and a full range of medium and high voltage electrical equipment.

Our product has been recognized by the Quality Supervision and Inspection Center for Insulators, Fuses, Lightning Arresters, and Overhead Line Equipment of the General Administration of Quality Supervision, Inspection and Quarantine of China, and has been tested by the National High Voltage Apparatus Quality Supervision and Inspection Center of China.

feature

1. The 1.24KV Dry Type Transformer strictly follows international/domestic standards such as ANSI, IEC, GB, SANS, etc., and has been tested by a national quality supervision and inspection center, meeting both performance and safety standards.

2. The lifting structure is stable, the wiring terminals are protected against electric shock, and the nameplate parameters of the transformer are clear, reducing the risk of manual errors. The design is humanized from transportation, installation to daily operation.

3. Cylindrical shell design, uniform heat dissipation and visually simple; The internal winding and iron core layout are compact, reducing electromagnetic interference and improving power supply stability.

4. The dry-type epoxy resin cast transformer adopts a fully sealed structure to isolate air, moisture, and dust, avoiding the insulation oil (or dry-type structure) from getting damp and aging, greatly extending the service life of the equipment, especially suitable for humid and dusty outdoor environments.

5. Optimization of winding process and iron core material to reduce no-load and load losses, and improve the overall energy efficiency of the power grid; Strong impact resistance during short circuit and overload, ensuring stable operation of the 'end power grid'.

6. The overload capacity design is reasonable, and stable power supply can still be achieved during short-term overloads (such as peak electricity consumption in rural areas during summer and winter); Under normal operating conditions, the energy efficiency ratio is high, and long-term operation saves electricity costs.

7. The winding is made of high-strength insulation material, and the iron core fixing structure is stable. The 24KV Dry Type Transformer has excellent short-circuit withstand capability; Thermal design adapts to power grid fluctuations and can operate reliably even in high temperature environments.

Product series and parameters

Advantage

1. Compared to its predecessor, the 13 series has further reduced no-load and load losses, higher energy efficiency levels, and lower long-term operating electricity costs.

2. Optimize winding design and insulation process, increase overload capacity by 10% -15% compared to conventional dry transformers, and handle sudden loads more calmly.

3. Epoxy resin casting insulation is oil-free, fireproof and explosion-proof, with a long maintenance free period (up to 10 years or more), suitable for commercial buildings, hospitals, schools and other places with high fire safety requirements.

4. The iron core of medium and high voltage electrical equipment is made of stacked high permeability silicon steel sheets, combined with optimized winding structure, and the sound level is controlled between 46-53dB to reduce noise interference to the surrounding environment.

Application Scenarios

1. Indoor Power Distribution: High-rise buildings, commercial complexes, hospitals, data centers, subway stations, and airport terminals.

2. Industrial Facilities: Workshops with strict fire safety requirements, cleanrooms, and chemical plant areas (including explosion-proof zones).

3. New Energy:

Wind Farms: Nacelle-mounted step-up transformers (e.g., 24kV/0.69kV) requiring resistance to vibration and extreme temperatures.

Photovoltaic (PV) Power Plants: Indoor step-up substations or outdoor installations with strict fire safety requirements.

4. Special Environments: Humid or dusty locations with good ventilation (requiring high ingress protection ratings such as IP54/IP65).

What are the installation requirements for 24kV dry-type transformers?

1. Ventilation and Heat Dissipation

Adequate clearance for heat dissipation must be maintained around and above the 24kV dry-type transformer; a minimum of 800mm is recommended.

Air inlets and outlets must not be obstructed, and a minimum distance of 40cm must be maintained between heat dissipation vents and surrounding objects.

For indoor installations, ensure the ventilation system is effective; install exhaust fans if necessary.

2. Moisture and Condensation Prevention

When installing in humid environments (such as basements), heaters or dehumidifiers must be provided.

If moisture ingress is suspected after a prolonged period of inactivity, the transformer must undergo a drying process; energization is permitted only after insulation resistance measurements meet the required standards.

3. Mechanical Securing

The transformer base must be secured in a level position to prevent fasteners from loosening due to operational vibration. Cooling fans must be securely installed, ensuring fan blades rotate freely without obstruction.

4. Electrical Connections

Busbar or cable connections must be tightened to standard torque specifications using a torque wrench and re-tightened periodically to prevent overheating caused by excessive contact resistance.

Cable entry is preferred for the high-voltage side rather than direct overhead connection, and zinc oxide surge arresters should be installed.
