Silane crosslinkable EPR compound for low and medium voltage power cable insulation SX505 pre-grafted base is mixed with a crosslinking catalyst masterbatch CM493 or CM497, in the ratio 95:5. The SX505:CM493 or SX505:CM497 systems have passed type-tests for use up to and including 33 kV. This compound is typically used in conjunction with crosslinkable semi-conducting material for conductor and insulation shields. Crosslinking is obtained by exposure to moist or hot water immersion only.

Silane crosslinkable EPR compound for low and medium voltage power cable insulation SX505NT pre-grafted base is mixed with a crosslinking catalyst masterbatch CM493 or CM497, in the ratio 95:5. The SX505NT:CM493 or SX505NT:CM497 systems have passed type-tests for use up to and including 36 kV. The graft compound contains a non-staining stabilizer and an effective tree retarder, giving outstanding long term retention of dielectric strength. This compound is typically used in conjunction with crosslinkable semi-conducting material for conductor and insulation shields. Crosslinking is obtained by exposure to moist or hot water immersion only.

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.
