Have individual product weightlessness the quantity is unqualified, easy ageing of insulation and jacket is degenerative.

2, function of individual product machinery is unqualified. The mechanical function of the standard insulation to different product and jacket raises different requirement. There is individual product in selectiving examination machine
Instrument function is unqualified, jacket or insulation are in lay in waiting for process getting power pull easily cause discharge of short circuit, leakage.

3, individual product heats up outspread project unqualified. The percentage elongation below the hot outspread load that the standard sets to cable is isolated from does not exceed 175% , permanent percentage elongation not more than
15% . There is individual product heat to delay in selectiving examination extend showed fusing phenomenon, cause short circuit accident easily below high temperature circumstance.

Be aimed at the main quality problem that in selectiving examination, discovers, total bureau of national qualitative check already enjoined technology of each district quality supervises a branch to wait for the regulation of concerned law laws and regulations strictly according to product quality standard, right the enterprise of off quality of the product in selectiving examination undertakes handling lawfully, deadline is rectified and reform.
