HJ0302-semi-conductive Insulation and Conductor shielding compound for MV Power cables

Application：

HJ0302 is a cross-linkable semi-conductive shielding compound, specially designed for both semi-conductive conductor and insulation shielding of the extrusion insulation power cables rated voltage up to 36KV.
It is suitable for dry vulcanization processing method at high temperature. It provides fine surface smoothness, nice extrusion flowability, good performance to prevent scorch and stable volume resistivity.

Specifications：

HJ0302 meets the applicable requirements as below when processed using sound extrusion practices and testing procedures.
-AEIC CS 7 and CS 8
-ICEA S-66-524/NEMA WC 7
-IEC 60502

Process Technology：

1、Temperature Setting of Extruder：

Zone	1#	2#	3#	4#	Tube	Head	Feeding、Water Cooling、Screw
Temp.	75℃	85℃	105℃	115℃	115℃	115℃	65℃

2、It’ s recommended to use stainless steel wire filter (20×40×20).

3、The above temperature setting are the most typical ones. With different extruder devices, it can be adjusted in terms of the practical situation after extrusion in use, combining with melting pressure and current, in order to achieve the best extrusion result.
