H Class Insulation Single Phase Pad Transformer

H class insulation single phase pad transformer has an insulation class of H and can adapt to most environments. It can withstand high temperatures and be used for a long time, making it very suitable for some harsh environments.

class insulation single phase pad transformer is a relatively high-grade transformer with high requirements for the casing. The insulation class is H grade, which can withstand high temperatures and is very stable. Suitable for most power distribution systems, it converts voltage to ensure the normal operation of the power system.

Rated capacity: 25kVA, 50kVA, 100kVA

Primary voltage: 10kV

Secondary voltage: 220V/110V

Insulation class: H grade

Cooling method: ONAN

Efficiency: ≥98%

Insulation heat resistance grade

H-class insulating materials can operate stably at a long-term working temperature of 180℃ and can withstand a short-term temperature of up to 220℃.

Compared with the common A-class, B-class and F-class insulation, H-class has A higher heat resistance margin and is suitable for high-temperature or overload working conditions.

Insulation system composition:

Winding wire: H-class enameled wire is adopted.

Interlayer insulation: Nomex paper or mica tape.

Impregnation process: Vacuum impregnation with silicone resin or epoxy resin to enhance moisture resistance and thermal conductivity.

It can adapt to high-temperature environments and still operate safely under an ambient temperature of 50℃ or short-term overload.

It has a very long lifespan. Due to the high-quality material of the shell, the aging speed is greatly slowed down, and it can generally be used for up to 30 years.

It can meet environmental protection requirements and is also very energy-efficient. Low loss, in compliance with the corresponding energy efficiency standards.

This transformer can be placed directly indoors or outdoors. Due to its excellent insulation, no additional casing is required for protection. It is best to place it in a well-ventilated and dry area, which can greatly increase the service life of the transformer. The fully sealed structure design makes maintenance very simple and convenient. You only need to regularly check whether the connection is normal and whether the appearance of the sleeve is worn.
