Single Phase XLPE Insulation Cable Copper Copper Tape Shield Electric Cable
XLPE is suitable for voltage ranges from low to extra high voltage, surpassing other insulation materials such as PVC, Ethylene Propylene Rubber (EPR) and silicone rubbers. Cross-linking the polyethylene also enhances the chemical and oil resistance at elevated temperatures and makes it suitable for use as a Low Smoke Zero Halogen material.
What’s the difference between XLPE insulation and PVC insulation?
XLPE is cross linked polyethylene material. PVC stands for polyvinyl chloride insulation.
The main difference between the two is that XLPE can be used for both high and low tension applications. Its structure provides great resistance to abrasion, stress, and other wear and tear. PVC insulation cannot withstand as much pressure, meaning it is only suitable for low tension applications.
Other differences:
XLPE insulation tends to last longer than PVC insulation
Since XLPE doesn’t contain chloride, it is more environmentally friendly
XLPE insulation can withstand higher temperatures
Cross linked polyethylene features more moisture resistance
