The excellent electrical performance of XLPE is the reason it is now used almost exclusively for insulating low voltage, distribution and transmission cables. While XLPE has far better resistance to moisture than paper insulation or PVC, moisture can affect long term performance of XLPE under the influence of high electrical stress. All low voltage and […]
Cable manufacturers must evaluate a range of properties when selecting a product as an insulating or cable sheathing material; properties such as electrical performance, mechanical properties including tensile and flexural behavior and, of course, the overall system cost. Another key parameter in the selection process is the fire safety of the cable – particularly the […]
Have you ever wondered how cables are tested to ensure safety? What sort of test are required by the standards and what properties do they quantify? We found the following article, which describes the testing of PVC cables very well.
