Overview

MYP cable for low smoke halogen-free cables used in coal mines is the abbreviation for mobile rubber sheathed flexible cables used in coal mines. M represents coal mines, Y represents mobile flexible cables, and P represents copper wire shielding.

Product Details

The cables are neatly wound on the cable delivery reel. The cable end is tightly sealed, and the length exposed outside the cable reel meets the requirements of the AC withstand voltage test, Only cables of the same model and specification are allowed to be wound on each cable reel. Prevent severe bending and other mechanical damage. coal mineUse low smoke halogen-free cablesLow smoke halogen-free cables for coal mines
