Main features

1.Protective functions to overload, short circuit, creepage, leakage lockout, over voltage, under voltage, over temperature, Adopted RS485 computer communication interface etc.

2. Excellent explosion-proof performance and mechanical strength.

3. Vertically lifted structure adopted.

4. Adopted cylinder- type HV winding to strengthen resistance to over- voltage.

5. Integrated HV and LV winding, increase mechanical strength and short-circuit resistance by .

vacuum-pressed dipped technology.

6. Excellent over-load resistance and insulated performance by using Dupont Nomex paper.

7.Fire-proof, nonpoisonous air created, low-noise, environment protected, non-maintaining.

 HV and LV switches have three configuration options:

A) Mining Flameproof HV vacuum switch + Mining Flameproof LV protection box 

B) Mining Flameproof HV vacuum switch + Mining Flameproof LV feed switch

C) Mining Flameproof HV vacuum switch + Mining Flameproof LV multi-loop combined switch(LMCC)

Flame-Proof Mining Mobile Transformers

Mining Flame Proof Mobile Substation is commonly applied for underground environment including in methane mixture gas and coal dust with potential explosion hazard in coal mine, nonferrous metal mine, tunnel engineering, etc .
