Ksg 2.5-50kVA 24-1440V Low-Voltage Three-Phase Explosion-Proof Dry-Type Transformer for Mine Lighting

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 dimensions1.
