It is a type of warm water cross linking material applied to low voltage wires and cables. It possesses following advantage: good electrical properties and anti-aging ability; excellent tensilestrength and low-temperature brittleness properties. In addition, the highest continuous workingtemperature is 125℃. This grade is compliant to EN 50618 and passed all properties except the20,000 hours aging test.
Application:
it is used for the insulation of solar cables
Specifications
High temperature resistance XLPO Compound for wires and cables up to 3KV.
