Insulation resistance testing (performed using an ohmmeter) is crucial for assessing the condition of transformers, but there is no universal "pass/fail" standard value. This is because the values can be affected by various factors.

The working principle of a transformer is based on Faraday's Law of Electromagnetic Induction and mutual induction.

power transformer on pole is a key equipment in the distribution network. If you need it, you can contact our company to obtain product information. It is mainly used to reduce the medium voltage power (such as 10kV) to low voltage power (220V/380V), which can be directly used by residents and commercial users.

What is the use of a power transformer?Power transformers are of vital importance in the power system. Their core function is to efficiently and safely transmit and distribute electrical energy. If you need power transformers, please contact our company.

The following is the table of prices for China's power transformers (calculated in US dollars). Our company produces various types of transformers. If you need them, please contact us. Please note that the prices can vary significantly depending on factors such as specifications, order quantity, raw material costs (especially copper and steel), and the manufacturer.

The core difference between oil-type (liquid-immersed) and dry-type transformers lies in their cooling/insulation medium and construction, leading to distinct advantages, limitations, and applications.

If you need dry-type transformers, please contact our company. China is a global leader in the manufacturing and export of dry-type transformers, providing a wide variety of transformer products at competitive prices.

Dry-type transformers are manufactured by using air and solid insulating materials. Our company produces various types of transformers. They possess safety, environmental friendliness, and flexibility for indoor installation. They are the preferred choice for most commercial, institutional, and many industrial applications, as these places do not allow the presence of fire risks or environmental pollution caused by liquid leakage.

The following are the recommendations of major transformer manufacturers in Malaysia, covering both local enterprises and international brands with their local branches or joint ventures. Our company produces various transformers suitable for power, industrial and infrastructure projects.
