The "five protections" in the electrical industry usually refer to the "five preventions" (five safety interlock functions for preventing electrical maloperation), which are the core mandatory requirements for ensuring the safety of personnel and equipment.I...

Reason: 1. There are no fuses on both the high-voltage and low-voltage sides of the distribution transformer. Some transformers, although equipped with drop-out fuses and fuse-links, use aluminum or copper instead of iron or copper for the fuse elements. As ...

The silicon steel of transformers generally uses oriented cold-rolled silicon steel sheets as the magnetic core material. Oriented cold-rolled silicon steel sheets include: traditional type, high magnetic conductivity type and laser-irradiated type. 1.Thick...

The main difference between the two is that they are adapted to different types of power supply and communication phases. The single-phase transformer is suitable for single-phase AC systems and supplies power to single-phase loads. 。 Three-phase transform...

Step 1: Conduct an initial visual inspection 1. Inspect the appearance of the insulation components: Check if the transformer's bushing has cracks, damage, or stains. 2. Inspect the transformer oil: Observe the color of the oil - whether it is clear, transpa...

From January 10th to 12th, 2026, the 11th Iraq Power and Energy Exhibition will be held at the Baghdad International Exhibition Center. As a professional manufacturer specializing in transformers, we will bring core products such as intelligent voltage stabi...

The transformer core is the magnetic circuit core component of the transformer. Its function is to conduct alternating magnetic flux, achieve electromagnetic induction between the primary and secondary windings, and determine the key performance indicators s...

The rectifier transformer is the power transformer of the rectification equipment. Its function is to convert alternating current into an alternating voltage suitable for the rectifier to work with, and then output a direct current through the rectifier. Wor...

ecently, the dry-type transformer equipped with an oil-loaded switch was completed with final tests at the production base and was successfully dispatched to Russia. These transformers were specially designed for the cold climate and complex power grid envir...

On December 7, 2025, a delegation from the Iranian Electricity Bureau's customers visited our factory for a site inspection. They focused on the technical performance, production capacity, and customized solutions of transformer products and had in-depth dis...
