Silane cross-linkable one-step insulation has two types, which are 4217 and 4216. It applies one step production technology by mixing different low density polyethylene base material and catalyst at a certain proportion. The product has good mechanical and electrical properties, excellent processability. And it is simple in processing and operation. It applies for low voltage up to 10kV.
| Type | Product Name | Colour | Usage |
| 4217 | XLPE Silane compound | Natural | Used for the cable insulation of low voltage up to 10kV |
| 4216 | XLPE Silane compound | Black | Used for the ABC cable insulation/sheath of low voltage up to 10kV |
