FAQS

1.What is an explosion-proof mining transformer and how does it differ from a regular transformer?

   Our explosion-proof mining transformer (KBSG/KSG series) is designed for hazardous underground coal mine environments with methane and coal dust. It features a flameproof enclosure that contains any internal explosion without propagating flames. Regular transformers lack this protection and are unsuitable for mines.

2.Which is better for mining: dry-type or oil-immersed transformers?

  Dry-type (KBSG series) is preferred for underground coal mines: no oil, non-flammable, zero leakage risk, and lower maintenance. It has become the industry standard over oil-immersed types.

3.How to select the right capacity for a mining transformer?

   Choose based on total load power. Common capacities: 315kVA, 500kVA, 800kVA, 1000kVA, etc. Recommend 20-30% headroom to prevent overload.

4.What are the installation requirements for mining transformers?

   Installation must be performed by certified electricians. Mount on level ground; use explosion-proof cable glands for connections. Post-installation explosion-proof inspection is required.

5.What are the typical applications for mining mobile substations (KBSGZY)?

   Ideal for fully mechanized coal mining faces. They integrate high/low-voltage switches, transformer, and feeder switches in a movable unit for quick relocation.

6.How to verify if a mining transformer is genuine?

   Check MA and explosion-proof certificate numbers on the official China Coal Safety website. Look for clear explosion-proof markings on the enclosure and complete manufacturer details on the nameplate.
