HEATSHRINKABLE
TUBING FOR MEDIUM
VOLTAGE BUS-BARS OF
HIGH THICKNESS

"SERIE STMT36KVAS"
SHRINK RATIO
> 2 ÷ 1

   Caratteristiche generali
 
Series STMT36KVMS heatshrinkable tubing has been created specifically for insulating medium voltage bus-bars of up to 36 KV. Because of the insulation properties of this tubing, the space between one bus-bar and the other can be reduced to one half or one third of the original space, and thus smaller electrical panels and conduits can be assembled.
