Taishan® resin casting dry-type transformer is designed for exceptional performance and reliability. With a capacity of 25 MVA, a voltage level of 35 kV, and a BIL level of 170 kV, it meets China’s national standards as well as ANSI and British standards. Known for its reliable operation and near-zero maintenance, it stands out as a high-quality, efficient solution.
The resin casting dry-type transformer is divided into two main winding types:
The HV winding adopts a sectional cylindrical structure, where copper wire, resin, and fiberglass combine for optimized heat dissipation and insulation. During the casting process:
This advanced design ensures the transformer delivers stable, safe, and efficient performance, even under demanding operating conditions.
The LV winding has the same structure with the above HV winding except for the Spiral winding structure. It has high mechanical strength, good moisture resistance. Wire insulation immersed in the resin, axial mechanical force is unlikely to reach the fastening structure.
The LV winding are wound by copper foils. Putting strip into winding and formed airway cooling. The LV winding layer is low voltage and low leakage at terminals.
Winding leading-out terminal use copper bar leads out. When winding finishing, both ends sealed by resin, the whole body become very strong. The insulation and the copper foil are bond together and damp-proof. Besides, the processing property is nice, the efficiency is high, the additional consumption is low and the short-circuit resistance is high.
The iron core adopts five-stage stepping joint so as to lower the no load loss. And the no load loss and noise level can be reduced as well by using the well-qualified cold-rolled grain-oriented silicon sheet steel, which is fastened or shaped by clamps and the black elastic resin paint and no punching on the surface of the iron core.
The clamp is formed into an entirety by steel cutting once so the structure is simple but beautiful. As the lifting lugs and clamp have become an integrated entirety so lifting the transformer will be safer.
Winding casting, no painting process.
Air Cooling System
The low noise cross flow fan has the characteristics of low noise, uniform cooling, and easy installation. After the air-cooled system is started, the transformer capacity can be increased to 150%.

Temperature Indicator of Dry-type Transformer
The safe operation and service life of the power transformer largely depend on the safety and reliability of the transformer winding. The insulation damage is caused by the winding temperature exceeding the insulation withstand temperature, which is one of the important reasons that the transformer cannot work properly.
The dry-type transformer temperature indicator (referred to as temperature indicator) is a kind of intelligent controller specially designed for the safe operation of dry-type transformer.
The temperature indicator based on SCM technology, using three platinum thermal resistance embedded in the three-phase winding of dry-type transformer to detect and display the transformer winding temperature rise, can automatically start and stop the cooling fan for forced air cooling of winding, avoid or reduce the fault caused by the transformer due to high temperature, and can control the over temperature alarm and over temperature tripping output, in order to ensure the operation of transformer in a safe state, so as to prolong the working life of transformer.
Dry-type OLTC
The voltage regulation can be realized under the condition of no power interruption, and the output voltage of the secondary side can be kept stable under the condition of voltage fluctuation of the grid. Improve power supply quality.
Live Locking
This series of products are suitable for indoor HV electrical equipment with rated voltage 3.6~40.5kV and frequency of 50 and 60HZ. According to its performance, mainly can be divided into two major categories:
The first kind is used separately and only has unlock functions, cannot be forced locking of electromagnetic locks. This kind of electromagnetic lock must be used in conjunction with the indoor HV live display device, and the locking contact can be locked in order to achieve the function of forced locking. It is an electric control mechanism interlocking device for preventing electric misoperation of a high-voltage switch device. The main use of electrical interlock between the indoor isolating switch and circuit breaker operating mechanism of the human in the switch cabinet door and other places of mandatory safety interlock to prevent misoperation and into live space, can effectively improve the anti-error performance of power supply equipment.
Another kind is to use separately to achieve the mandatory locking function. The utility model integrates the live display and the forced locking function, and can be used in conjunction with the sensor to reflect the electrified condition of the HV circuit, and can realize the forced shutting function. The utility model is mainly assembled in front of the switch cabinet, the back door and other parts which need to be locked. The utility model can reliably prevent the electric misoperation, prevent the mistake from entering the electrified interval, and improve the error proofing performance of the matched products.
As mentioned before, due to the good performance of the resin casting dry transformer, the applicable range is very wide.
The power supply of the fast transient system will cause the transformer to suffer short-time burst overload, which can be several times of the rated continuous load. This happens when the electric locomotive accelerates the closing of feed connections. The greater the overload is, the greater the impact of short-term overload on the transformer. The thermal time constant of cast resin transformer winding is 40 minutes, the time constant of the corresponding oil-immersed transformer is not more than 10 minutes, the difference is great, that is to say, pouring type transformer can design smaller than the oil-immersed transformer, but the short-term overload capacity is high.
Other uses of the resin structure, such as motor starting device, core or coreless current limiting reactor, are also widely applied.
In fact, the transformer used in many occasions has higher reliability and economy by adopting the structure of pouring resin. Resin insulated transformer because of its low loss, low noise, low partial discharge, flame self-extinguishing, without maintenance, it can be widely used in high-rise residential, office buildings, business center, underground railway, etc. In any case where an oil-immersed transformer can not be used, the resin transformer can be used and has high reliability. It is comparable to an oil-immersed transformer in terms of electrical performance, but is a leader in mechanical properties.
In the design of distribution system, considering the application of cast resin transformer is a foresighted view. In most cases, the start-up cost of the resin transformer is higher, but the protection is low cost, low loss and almost no maintenance. As far as the total cost of installation is concerned, it is more economical.
Glass fiber resin pouring structure can achieve the same power frequency and impulse level as oil-immersed transformers, and some design structures have impulse levels exceeding 200kV.
The cast type transformer has already withstood the test voltage (HV to HV, HV to LV to ground) and operating voltage in the atmospheric environment. Wire winding inter-turn and inter-layer only have a tiny differential pressure, are absorbed by the resin itself, and reached a very safe level. The inter-layer voltage of the foil winding is only the minimum voltage of each turn, the end of the winding has no helical angle, the magnetic leakage area is small, and the axial short-circuit resistance is strong. As the air-based insulation, this part of the insulation system will not deteriorate, will not age.
The wire winding adopts vacuum casting to obtain a uniform insulation structure, eliminates bubbles and voids, and avoids partial discharge in the winding. The inter-layer voltage of the foil winding is low and no partial discharge.
According to the IEC60076 standard, partial discharge tests shall be carried out on fully assembled transformers. In order to confirm the high quality of the design and production, the partial discharge test of each HV winding is carried out before the assembly.
In this way, the insulation in the HV winding can be checked to meet the quality requirements. The partial discharge termination voltage is at least 1.2 times than the rated voltage, and in most cases, even 2 times than the rated voltage. It is proved by this test that the winding is qualified.
Glass fiber reinforced winding will not crack due to sudden fluctuations in temperature or thermal impulse.
Wire winding has been heated to the rated temperature, and then placed in ice water to cool for temperature change resistance test. All winding can pass such destructive tests.
Due to insulation and copper foil adhesive curing as a whole throughout the winding and the Foil winding is not cracking due to temperature fluctuations or sudden thermal shock.
According to Table III of the IEC 60076-5 standard, the maximum allowable average temperature of conductors after a short circuit for B, F, and H-class insulated copper wires is 350°C. For F-class copper winding transformers, the time “t” is determined, and after this duration, the final temperature will be:
T1 = T0 + a.Sk2.10–3[℃]
Among this:
The following is calculated by the upper figure:
As all protection devices can cut off the transformer power within 10 seconds, the margin shown in this example is very large.
When the transformer is short-circuited, the conductor is heated rapidly in a matter of seconds. The resin around it is better than the conductor, can only be slowly heated, the conductor and resin surface temperature gradient will be great, and the greater the thickness of resin wrapped, and its gradient is too large. Even when the expansion coefficient is well matched, the mechanical strength of the winding must be taken into account, but the elastic glass fiber resin structure can be used to prevent cracking under the above conditions.
The wire wound products are very well protected against moisture due to the copper conductor complete encapsulation in resin insulation. The transformer can be networked after long-term storage, and can be input into the power grid no-load.
The foil winding shall be stored in damp proof, and when the insulation resistance is lowered, it should be heated and dried before it can be put into use. When using, only compressed air can be used to remove sediment or dust.
The main concern of resin casting dry-type transformer is environmental protection. This question is actually a justification for the development of a cast type transformer:
The main feature of the resin casting transformer is flame retardant and self-extinguishing. Tests have shown that once a fault occurs inside the transformer and the protection device cuts off the transformer within the specified time, the winding itself will self-extinguish, thereby stopping the fire. If the external environment catches fire and all equipment and buildings are on fire, the epoxy resin may also burn, but the burning of the resin will not promote the spread of the fire.
The toxic components of combustion products are a major concern. Simulated tests were conducted in laboratories. Depending on the conditions and analysis methods, the results vary. According to OSHA requirements, if toxic substances are present, their concentrations are very low, allowing for prolonged exposure without harm.
In the wire wound transformer, the winding is not mechanically connected with the core, but the support structure is used to prevent the core ferromagnetic vibration from transmitting to the winding.
The winding and the core are supported by special materials in the foil winding transformer structure, which effectively reduces the ferromagnetic vibration and reduces the superposition of noise.
The outer surface of the core is covered with elastic resin, which can prevent further noise transmission, and its noise level is better than the national standard.
Wire wound and foil wound transformers are completely dry structures with no liquid or gas insulation, so there is no leakage. There is no need to take additional measures to prevent leakage, so there is no pollution to the environment.
