Application:
SEJ90-1-KK (10) is one-step silane cross-linkable polyethylene overhead insulation compound for medium-low voltage cables. It is a kind of
insulations for medium-low voltage overhead cables through squeeze tube mold production process. Cables working voltage is 10KV and
below, the highest working temperature is 90℃.
Processing Indicator
Recommend to process with the PE extruder.
