Silane crosslinkable EPR compound for low and medium voltage power cable insulation

SX554 pre-grafted base is mixed with a crosslinking catalyst masterbatch CM493, in the ratio 95:5, or CM497, in the ratio between 90:10 and 93:7.CM493 is a stronger catalyst suitable for wall thicknesses > 1.5mm and CM497 is a weaker catalyst suitable for small conductor sizes, such as 1 to 4 mm².

The system SX554:CM493 or SX554:CM497, has been approved for use at 1kV and has found uses up to 10kV, it is highly flexible and enables the production of soft rubber cables without the use of continuous vulcanization equipment. Crosslinking is obtained by exposure to moist or hot water immersion only.
