XLPE power cable is no Greek and Latin. These are “Cross-linked polyethylene” cables that have a typical linear molecular structure. The molecules in polyethylene are not bonded chemically and therefore when exposed to high temperature, they can be easily deformed. When these are bonded in a network that is three dimensional, then they gain immense resistance and cannot be deformed even when exposed to extreme temperature.
XLPE power cables due to their low level dielectric loss, they can be great insulators when it comes to medium or high voltage cables. With the favorable dielectric constant, XLPE cables have a low mutual capacitance and so they reduce charging currents in networks especially without star-point earthing attracting earth-leakage currents.
When it comes to the design, the XLPE power cable totally stand in par with the international quality standards and are almost the same as those cables that are best suit for medium and high voltage. The XLPE power cables are believed to be one of the most reliable cables as they are supplied with the intrinsic cross-linked semi-conducting screen that greatly protect the XLPE insulation.
With the semi-conducting screen, the interstices in between the wires are artistically filled facilitating a smooth and circular envelope all around the conductor diminishing the effect of flux lines around the single wires thereby safeguarding the conductor from any possible electrical stress.
The insulation screen is available as a strippable or as a bonded one for cables as per customer requirements and the bonded screen is specifically used for cables designed to handle high voltages.
With an intrinsic and careful designing, the XLPE power cables provide extraordinary performance and they also last long. Most customers prefer XLPE power cables, for they are exclusively designed to handle high voltages and are less likely to cause any distortions in the power supply.
