Shanghai Municipal Bureau of Quality Supervision randomly inspected 6 batches of plastic insulated control cable products, all qualified

On July 20, the official website of Shanghai Municipal Bureau of Quality and Technical Supervision announced the results
of the 2018 Shanghai plastic insulated control cable product quality supervision and random inspection.
This time, 6 batches of products were randomly inspected, and all of them were qualified
after inspection.

According to the requirements of GB/T 9330 "Plastic Insulated Control Cable" standard, the following items of the product were inspected: average insulation thickness, thickness at the thinnest point of insulation, sheath thickness, armored metal strip, conductor resistance, insulation resistance, finished cable voltage test, insulated core voltage test, tensile strength before insulation aging, elongation at break before insulation aging, tensile strength after insulation aging, elongation at break after insulation aging, tensile strength change rate before and after insulation aging, Elongation at break before and after insulation aging, loss on insulation, low temperature bending of insulation, low temperature impact of insulation, thermal shock of insulation, tensile strength of sheath before aging, elongation at break before sheath aging, tensile strength of sheath after aging, elongation at break after sheath aging, change rate of tensile strength before and after sheath aging, change rate of elongation at break before and after sheath aging, loss on sheath, thermal shock of sheath, low-temperature bending/stretching of sheath, low-temperature impact of sheath, combustion performance of a single cable of finished cable, printing
