Kabel Material-Peroxid-Vernetzung PE Kabel Insu

Peroxide Crosslinking PE Cable Insulating Material Peroxide crosslinking PE cable insulating material which uses LDPE resin as tis basic material is formed through the process of politicizing,granulating by mixing with anti-oxidant,crosslinking agents etc.Our company produces three grades products:YJ-3,YJ-10andYJ-35.The property and uses of these products are listed as following table. Use Sequence number Model number Name Max allowable working temperature of conductor core Use 1YJ-3 3KV crosslinked PE Cable insulating material 90°C Insulating layer for crosslinked PE Cable under 3Kv 2YJ-10 10Kv crosslinked PE Cable insulating material 90°C Insulating layer for crosslinked PE Cable under 10Kv 3YJ-35 35KV crosslinked PE Cable insulating material for aerial cable 90°C Insulating layer for cross linked PE aerial cable under 35Kv Specifications Item Model numb Unit YJ-3 YJ-10 YJ-35 Tensile strength≥ MPa 13.5 13.5 13.5 Tensile elongation at break≥ % 350 350 350 Brittleness temperature≤ °C -76 -76 -76 135°C 168h oven ageing Variation of tenstle strength % ±20 ±20 ±20 Variation of elongation at break % ±20 ±20 ±20 200°C,0.2Mpa,15min heat extend Loaded elongation % 80 80 80 Permanent deformation after coding % 5 5 5 50Hz,20°C Dielectnc constant≤ - 2.35 2.35 Dielectnc Loss fangent≤ - 1*10-3 5*10-4 Volume Resistivity 20°C≥ Ω.m 1*1014 1*1014 1*1014 Dielectric strength≥ MV/m 25 25 25 Gel Conetent≥ % 80 80 80
