Product DescriptionKSG type mine explosion-proof dry-type
transformer (hereinafter referred to as transformer) is suitable
for explosion-hazardous places with coal dust underground in coal
mines. In AC 50Hz/voltage to 660V power supply line/provide 127V
power supply for coal drill . Transformers are designed,
manufactured and inspected in accordance with GB3836.1-83 "General
Requirements for Explosion-Proof Electrical Equipment for Explosive
Atmospheres" GB3836.2-83 "Explosion-proof Electrical Equipment for
Explosive Atmospheres Flameproof Electrical Equipment "d"" and
other relevant standards.Mine transformers are divided into:
general and flameproof underground mine transformers. The general
type is used in places where there is coal dust and biogas without
explosion in mines, electric drive and lighting. This transformer
is oil-immersed. Explosion-proof transformers are used in places
where there is a danger of explosion in mines. This transformer is
dry type.Model DescriptionTechnical parameters and structure
