national cable quality inspection center: strictly control the quality of conductive layer

release date:

core tip: "the cable industry must strictly control the quality of semi conductive layer of cable outer sheath." On August 24, Wu Changshun, director of the national wire and cable quality supervision and inspection center and professor level senior engineer, said in a report with the theme of "paying attention to the quality control of high voltage cable products under the situation of overcapacity" at the "new technology exchange meeting of ultra high voltage cables and energy-saving conductors". The wire and cable industry must strictly control the quality problem that the appearance of the semi guide screw of the cable outer sheath should be 1 directly coated with a new grease electric layer.

he said that for a long time, in view of the fact that the graphite coating is easy to fall off in actual use, material researchers and cable manufacturers have carried out some research work, including the modification of conductive coating materials and the improvement of coating process, and successively put forward methods such as wear-resistant conductive coating and extruding the conductive layer. Although great progress has been made in the materials and processes of the conductive layer at present, the phenomenon that the graphite coating is easy to fall off and the graphite coating and extruded conductive layer are non-conductive still exists from many tests

this conference was held in Guangzhou, hosted by Far East Cable Co., Ltd. and undertaken by Southern Media Co., Ltd. More than 80 leaders and power planning professionals from Nanfang power and national HP proposed to enter the $12 trillion manufacturing field, including the 3D printing strategy, the wire and cable quality supervision and inspection center, and the power cable Standardization Technical Committee of the power industry
