Inter pole coupling transformer inter stage coupling transformer is used between two-stage sound integrated inductors, Rao line inductors, inductor manufacturers, Shenzhen inductors and electronic news frequency amplification circuits. As a coupling element, it transmits the output signal of the previous amplification circuit to the next stage and makes appropriate impedance transformation. Input transformer in the early semiconductor radio, the transformer used between the audio integrated inductor, Rao line inductor, inductor manufacturer, Ningbo inductor, electronic news promotion stage and power amplification stage is the input transformer, which plays the role of signal coupling and transmission, also known as the push transformer. The input transformer has single ended input type and push-pull input type. If the push circuit is a single ended circuit, the input transformer is also a single ended input transformer; If the push-pull circuit is a push-pull circuit, the input transformer is also a push-pull input transformer. 3. The output transformer is connected between the output circuit of the power amplifier and the loudspeaker, which mainly plays the role of signal transmission and impedance matching.

Disadvantages of fully sealed transformers

The price of expansion and contraction components for fully sealed transformer oil volume changes (corrugated sheets or expansion radiators) is relatively high, especially for their production equipment such as corrugated oil tank production lines Make the cost of fully sealed transformers higher and the product price more expensive. The corrugated fins of the corrugated fuel tank and the expansion fins of the expansion radiator cannot be made very thick due to their elasticity. In case of oil leakage, welding repair will be more difficult.

Fully sealed transformers some have oil level indicators; Some do not have an oil level indicator and require a probe to measure the oil level, which makes it difficult to monitor the oil level and color.

For commercial applications where airborne contaminants are present, HPS general-purpose encapsulated transformers offer a cost-effective solution that prioritizes safety, quality and ease of installation and maintenance.

The core and coil are completely encapsulated in epoxy and silica, providing excellent protection against airborne particles and moisture build-up inside the transformer enclosure.

Encapsulated transformers include transformers that are enclosed in a casing or coating. Transformers are encapsulated to protect components from contaminants present in the working environment, such as moisture, gases, dust, or dirt. They may also be encapsulated to meet spark-resistance requirements (for use near potentially explosive gases for example).

In addition to environmental protection, encapsulation can also dissipate heat from the core and windings, reducing temperature differentials around the windings and enabling the transformer to perform reliably in higher-temperature environments.
