What is difference between PVC cable & XLPE cable?
Answer Posted / k.sydulu babu
xlpe is known as cross linked poly ethelyene it can with
stand for higher temperature(90'c) as compared to pvc.It
has high mechanical strength.As compared to pvc it is
better for underground laying of cables for higher
temperature.
