Abstract
The present arrangement provides for an electric cable having at least one insulated conductor and a jacket surrounding the at least one insulated conductor. The polymer composition of the jacket includes at least a base polymer, a first lubricant and a second lubricant. The first lubricant is paraffin oil lubricant included in the polymer composition of the jacket in the range of 0.8%-2% by weight and the second lubricant is a siloxane lubricant included in the polymer composition of the jacket in the range of 0.25%-1.0% by weight.
