HG Fuse is useful in protecting insulators where there are high voltage electric power transmission system so that there would be no damage during an unintended electric discharge. The range between the fuses is 33KV to 100A. The company manufactures these devices so that the operation runs without any hinges. The switches are made of pressurized electroplating of metal, so that the fuse may have a long life. There are several tests an HG Fuse need to go through in order to meet the high standards of the company, and only then they are allowed to be used by the consumer.
